Accessory Devices
In addition to the devices that are included with the PowerBook Duo 280 and 280c computers, the following accessory devices are available:
n The PowerBook Duo 8 MB Memory Expansion Kit expands the RAM in the computers to 12 MB.
n The PowerBook Duo Battery Type III is available separately as an additional or replacement battery.
n The Power Adapter II, the AC adapter that comes with the computers, is also available separately.
All the other accessories for the PowerBook Duo family will work with the PowerBook Duo 280 and 280c computers, including memory expansion, docking units, and modems.
Compatibility Issues
The PowerBook Duo 280 and 280c computers have several new features that distinguish them from the first models in the PowerBook Duo family. This section highlights key areas you should investigate in order to ensure that your hardware and software work properly with these new computers.
Number of Colors
The controller circuitry for the flat panel display includes a 256-entry color lookup table (CLUT) and is compatible with software that uses QuickDraw and the Palette Manager. The controller supports a palette of 32,768 colors. However, due to the nature of color LCD technology, some colors are dithered or exhibit noticeable flicker. Apple has developed a new gamma table for the color displays that minimizes flicker and optimizes the available colors. For the active matrix color display, the effective range
of the CLUT is about 4,000 colors.
Note
The color display on the PowerBook Duo 280c is similar
to the one on the PowerBook Duo 270c.u
See the section “Displays” beginning on page 11 for more information about the internal display hardware and LCD screen.
Power Manager Interface
Starting with the PowerBook Duo 250 and 270c models and continuing with the PowerBook Duo 280 and 280c, the system software includes interface routines for program access to the functions of the Power Manager. Henceforth, developers should not depend on the Power Manager’s internal data structures being the same on different PowerBook models. In particular, developers should beware of making any of the following assumptions regarding different PowerBook models:
n assuming that timeout values such as the hard disk spindown time reside at the same locations in parameter RAM
n assuming that the power cycling process works the same way or uses the same parameters
n assuming that direct commands to the Power Manager microcontroller are supported on all models
For more information, see Chapter 4, “Power Manager Interface.”
RAM Expansion
In the PowerBook Duo 280 and 280c computers, the RAM expansion connector has
an additional signal, RAS(7) on pin 24, that provides addressing for up to 36 MB of expansion RAM. A RAM expansion card for the newer machines also works in the older machines, except that any RAM over 32 MB is ignored.
MacsBug Version 6.2.2
MacsBug version 6.2.2 does work on the PowerBook Duo 280 and 280c computers because it assumes that all MC68040 microprocessors have built-in FPUs. That problem is corrected in newer versions of MacsBug.
The PDS and the MC68030 Bus
Even though the PowerBook Duo 280 and 280c computers have MC68LC040 micro-
processors, they support processor-direct slot (PDS) cards designed for the MC68030 bus. The MBT custom IC provides the bus interface, as described in the section “Bus Translator IC” on page 10. The MBT was designed to support the MC68030 bus, but some subtle features are not supported. Here is a summary of the differences.
n Late retry or late bus error operations are not supported. If a device asserts the /BERR signal or /BERR and /HALT without other termination, those signals must conform to the /DSACK timing. If a device asserts /BERR or /BERR and /HALT along with
/STERM, those signals must be valid on the same rising edge as /STERM.
n A device should not assert the /HALT signal by itself; doing so does not halt the processor.
n When a device asserts the cache burst acknowledge signal, the device must perform a burst of four longwords, wrapping addresses when necessary, unless it asserts the bus error signal along with the /STERM signal.
n A device must not assert retry after the initial cycle of a burst; the MBT and the MC68LC040 interpret that condition as a bus error and abort the burst.
n The MBT does not support burst cycles of one clock width. The fastest burst cycle allowed consists of 2-2-2-2 clocks.
n The MC68LC040 microprocessor and the MBT do not support the coprocessor interface of the MC68030 microprocessor.
n When the processor has the bus, the MBT drives the function code 0 signal high and the function code 1 signal low, which designates all cycles as data space cycles.
n The cache inhibit out signal on the PDS is low, preventing external caches.
n Signals ECS, OCS, FC2, and DBEN are not provided; they have never been provided on the PDS.
n Interrupt acknowledge cycles are not present on the PDS.
n Breakpoint acknowledge cycles are not present on the PDS.
Future models of the PowerBook Duo will continue to support the 152-pin PDS, but their architecture may change such that some MC68030 modes may not be supported. The following microprocessor modes may not be supported in future models.
n The bus grant signal may not always be asserted within 3.5 clocks of the assertion of the bus request signal even if /RMC is not asserted.
n Ownership of the MC68030 bus extends to all other buses. Relinquish and retry opera-
tions will not be supported during dynamic bus sizing or while /RMC is asserted.
n Burst mode from PDS space will not be possible; the computer will never assert the cache burst request signal to the PDS.
n Alternative bus masters will not receive a cache burst acknowledge when they read or write to ROM or DRAM address space.
Hardware Features
This chapter describes hardware features of the PowerBook Duo 280 and 280c computers that make them different from the original Macintosh PowerBook Duo computers described in Macintosh Developer Note Number 2. The new features include several changes to the main logic board as well as changes to the display, the internal hard disk, the inverter/speaker board, and the clamshell housing.
Changes on the Main Logic Board
The outline of the main logic board in the PowerBook Duo 280 and 280c computers is identical to the outline of the main logic board in the original PowerBook Duo models. However, there are several component changes, as described in the following section. Figure 2-1 is a diagram of the main logic board, with the new components shaded.
The changes to the main logic board board are
n replacement of the MC68030 microprocessor with the MC68LC040
n addition of the MBT (microprocessor bus translator)
n replacement of the GSC (grayscale controller) with the CSC (color screen controller)
Figure 2-1 Main logic board
n rearrangement of the on-board DRAM
n rearrangement of the on-board VRAM and ROM
Figure 2-2 is a block diagram showing the relationship of the microprocessor and the MBT to the other ICs on the logic board.
Figure 2-2 Block diagram
MC68LC040 Microprocessor
The microprocessor used in the PowerBook Duo 280 and 280c computers is the MC68LC040. The MC68LC040 includes a built-in MMU (memory management unit) that performs the memory-mapping functions.
IMPORTANT
The MC68LC040 does not contain an FPU (floating-point unit).
There is no FPU upgrade for the PowerBook Duo 280 and 280c computers and those computers cannot use the external FPU in
the Duo Dock and Duo Dock II.s
The MC68LC040 microprocessor runs at an internal clock rate that is double its external clock rate. The MC68LC040 in the PowerBook Duo 280 and 280c computers has an external clock rate of 33 MHz and an internal clock rate of 66 MHz.
The PowerBook Duo 280 and Duo 280c do not support external direct-mapped caches and will not make use of the 32KB SRAM cache in the Duo Dock II.
Bus Translator IC
A custom IC called the MBT (microprocessor bus translator) provides the translation necessary for the MC68LC040 to work with devices designed for the MC68030. The MBT translates all MC68040 cycles except acknowledge cycles to MC68030 cycles.
Because the MC68LC040 does not support dynamic bus sizing as the MC68030 did, the MBT generates the multiple MC68030 cycles needed to obtain longword data from byte and word devices. For byte and word reads, the MC68LC040 obtains the data in the appropriate byte lanes based on the low-order address lines. The MBT maps the MC68030 read data from the high byte lanes to the correct byte lanes. For write operations, the MBT performs the byte smearing needed for byte and word operations.
The MBT handles retry requests without involving the MC68LC040. It also performs relinquish and retry operations to prevent stalemate conditions that might arise with alternate bus masters.
The MC68LC040 supports burst mode on both read and write operations. The MBT supports burst-mode write operations to the first 64 MB of RAM because the MSC acknowledges that address space and supports burst-mode writes. On the other hand, the MC68030 did not support burst-mode writes, so devices designed for the MC68030 bus may not handle the /CBREQ signal on write operations. To avoid potential problems with such devices, the MBT blocks burst writes to locations other than RAM.
Burst cycles must wrap to address four longwords. The MC68LC040 has one valid bit per cache line and each cache line contains four longwords. The MC68LC040 looks at the transfer burst inhibit signal at the first assertion of the transfer acknowledge signal to determine whether the device indicates its ability to support a burst. If the transfer burst inhibit signal is negated (high), the MC68LC040 requires the responding device either to wrap the addresses around so that the entire four longwords in the cache line are filled by the single operation or else to terminate early with a bus error.
On the MC68LC040, both the transfer acknowledge signal and the transfer error acknowledge signal must be valid 10 ns before a rising clock edge. To avoid having the MBT add an extra clock to every cycle, the corresponding signals on the MC68030 bus must be valid on the previous rising edge. That means the MBT does not support late retry or bus errors. If a device asserts the /BERR signal with /STERM, or /BERR and
/HALT with /STERM, those signals must meet the timing specification for /STERM with respect to the rising clock edge. If a device asserts /BERR or /BERR and /HALT
by themselves or in combination with /DSACK, the signals must meet the timing specification for /DSACK with respect to the falling clock edge. A device should not assert the /HALT signal by itself; doing so does not terminate the cycle or halt
the MC68LC040.
Color Screen Controller IC
A custom IC called the color screen controller (CSC) replaces the grayscale controller (GSC) used in the original PowerBook Duo. Figure 2-1 shows the location of the CSC on the main logic board. The CSC can support either supertwist or active matrix displays, in color or grayscale. The CSC operates in either of two display configurations: 640 by 480 and 640 by 400. It supports the following pixel depths:
n 1 bit per pixel (black-and-white only)
n 2 bits per pixel (4 colors or gray levels)
n 4 bits per pixel (16 colors or gray levels)
n 8 bits per pixel (256 colors or gray levels)
n 16 bits per pixel (32K colors), with 640-by-400-pixel display
DRAM Locations
The main logic board in the PowerBook Duo 280 and 280c computers contains 8 DRAM chips, which make up the 4 MB of onboard DRAM. Four of the DRAM chips are located on the front of the main logic board, and four are located on the back of the board. This is the same arrangement used in the PowerBook Duo 250 and 270 models.
The expansion RAM connector has one additional signal, RAS(7) on pin 24, that allows the PowerBook Duo 280 and Duo 280c computers to address up to 36 MB of expansion memory and gives them a total RAM capability of 40 MB. For information about the expansion RAM connector, see pages 65–72 of Macintosh Developer Note Number 2.
VRAM Locations
The 512KB display buffer on the main logic board consists of 2 VRAM chips. One of the VRAM chips is located on the front of the main logic board and one is located on the back of the board.
Displays
The PowerBook Duo 280 computer has a grayscale display and the PowerBook Duo 280c has a color display. Both are liquid-crystal flat panel displays using active-matrix TFT (thin-film transistor) technology, and both have a built-in backlight using a CCFL (cold cathode fluorescent) lamp.
The active matrix technology used in both displays provides a high contrast ratio (60:1) and response time of approximately 60 milliseconds, for performance similar to a CRT video display and with no cursor smearing or cursor submarining.
Both displays normally display black characters on a white background, simulating the appearance of a printed page. The next two sections describe the features of the two types of displays.
Note
The grayscale display in the PowerBook Duo 280 computer is exactly like the display in the PowerBook Duo 250; the color display in the PowerBook Duo 280c computer is exactly like the display in the PowerBook Duo 270c.u
Grayscale Display
The grayscale display in the PowerBook Duo 280 is an active matrix liquid crystal display. It meets the same form factors as the basic PowerBook Duo display, so no modifications are required to the computer housing. Each pixel in the grayscale display’s 640-by-400-pixel array is controlled by its corresponding transistor, for a total of 256,000 transistors.
Color Display
The color display in the PowerBook Duo 280c computer is an active matrix TFT color display. It is 3.8 millimeters thicker than the grayscale display used in the original PowerBook Duo, requiring the PowerBook Duo 280c computer’s case to be thicker than that of the original PowerBook Duo. (See the section “Clamshell Case” on page 21.)
The color display can operate in either of two modes. In 8-bit mode the display has a 640-by-480-pixel area and can display up to 256 different colors at a time. In 16-bit mode the display has a 640-by-400-pixel area and can display thousands of colors.
Note
The number of colors available in 16-bit mode is less than the theoretical maximum due to the limitations in the color LCD technology. Many color values exhibit noticeable flicker. The computer’s CLUT omits the unsatisfactory colors, making about 4,000 available. See the Appendix, “Color Lookup Table,” for more information.u
The user can select either color display mode by means of the Monitors control panel. Because the VRAM is a fixed size, 256K by 16 bits, it can handle only a certain amount of data. When the user selects 16-bit mode, the system software resizes the display area down to 400 lines instead of 480 and centers the display area on the screen, leaving black bands of 40 lines each at the top and bottom of the screen.

The drive may be installed by means of holes in either the side or the bottom of the disk drive housing. A bracket, shown in Figure 2-4, is attached to the side of the hard disk and holds it in place in the PowerBook Duo 280 and 280c computers.
Figure 2-3 Hard disk drive installation
Figure 2-4 Bracket for the hard disk drive
Hard Disk Interface
This section describes the interface requirements for the 240 MB hard disk drive and provides specifications and signal assignments for the SCSI connector.
The interface to the hard disk is an ANSC X3T9.2 SCSI interface. It implements the Apple SCSI command protocol and diagnostic command set. Buffer size supports a 1:1 interleave. The drive supports the SCSI asynchronous information transfer. The transfer rate is 1.5 MB per second (minimum). An embedded controller provides error recovery algorithms, which include error check and correction (ECC), seek retry, head offset (for open-loop systems), and defect management. The SCSI interface provides a SCSI ID that can be detected by the hardware.
SCSI Connector
The disk drive connector comprises two segments, as shown in Figure 2-5. The first segment has 40 pins, arranged in two rows. It transfers SCSI signals between the CPU and the hard disk drive, and it also supplies power to the drive. The second segment of the connector has 8 pins and provides the SCSI ID encoding.
Figure 2-5 Connector for the hard disk drive
Table 2-2 lists the interface signals for the 40-pin segment of the connector.

Terminator
The hard disk has 1000-ohm termination resistors for all I/O signal lines. The lines are pulled up through the resistors to the terminator power signal.
Power Requirements
Power drawn by the hard disk signals in each operating mode must be less than or equal to the values shown in Table 2-5. All measurements are under nominal environmental and voltage conditions. The limits include 1000-ohm pull-up resistors on all signal lines.

* Startup values are peak values during response time of power on to power ready. † Random operation values are RMS values with a
40 percent random seek, 40 percent write/read (1 write in 10 reads), and 20 percent idle mode.
Inverter/Speaker Board
The inverter/speaker board is located in the clamshell housing, directly under the display. It is the interface between the main logic board and the display and performs
the following basic functions:
n It converts the DC power supplied by the computer’s battery to the AC power required to drive the cold cathode fluorescent lamp (CCFL) that provides the backlighting for the active-matrix LCD display. Typical CCFL drive power is 400 VRMS (volts root mean square) at 3 mA, with maximum output of 2000 V peak
to peak at 6 mA.
n It provides pass-through circuitry, both for the data and timing signals from the CSC to the LCD display, and for the +5 V from the power supply.
n It converts the DC voltage supplied by the computer’s battery to the voltage level required for the LCD bias, which is typically +5 V at 200 mA.
sWARNING
You should not open or modify any of the circuitry associated with the inverter/speaker board. The flat-panel display is assembled into the clamshell housing in a clean room environment. Opening up the equipment in any other environment could cause damage to the unit. The high voltage on the inverter/speaker board may pose a risk to someone handling the board. The display is also susceptible to damage from electrostatic discharge.s
Clamshell Case
The PowerBook Duo 280 and 280c computers are housed in a clamshell case. Because the display in those computers is 3.8 millimeters (0.149 inches) thicker than the one in the original PowerBook Duo, the case is also thicker than the original PowerBook Duo case. When the case is closed, it measures 203.2 millimeters by 274.32 millimeters (8 inches by 10.8 inches) and is 36.8 millimeters (1.449 inches) deep. Figure 2-6 shows a view of an open clamshell case.
Figure 2-6 The computer in open position
IMPORTANT
IMPORTANT
Because the clamshell case is slightly deeper than the case of the original PowerBook Duo, you cannot use a standard Duo Dock with the PowerBook Duo 280 and 280c computers. The slot in the Duo Dock is not deep enough to accommodate the computer’s case. There are two solutions. You may upgrade the top shell of an existing Duo Dock to enlarge the slot, or you may purchase the new Duo Dock II, which can accommodate the deeper case without modification. s
Software Features
This chapter describes the new ROM and system software features of the PowerBook Duo 280 and 280c computers. It also tells how to add modules to the control strip.
ROM Software
The ROM software in the PowerBook Duo 280 and 280c computers is based on the ROM used in previous PowerBook computers, with enhancements to support the many new features of this computer. Some of the features this ROM was designed to support include the following:
n MC68LC040 microprocessor
n built-in color and grayscale displays
n refresh operation for up to 40 MB of DRAM
n extended power management capabilities
n improved support for the AppleTalk network
The ROM also supports several docking station features, such as an external cache, and enhancements to the docking process.
The ROM version number in the PowerBook Duo 280 and 280c computers is $67C and the CPU ID bits are $A55A 1000. The box flag for the PowerBook Duo 280 is 96; for the PowerBook Duo 280c it is 97. The corresponding gestaltMachineID values are 102 and 103 respectively. Notice that the CPU ID bits are the same for both models; the box flag and gestaltMachineID values are determined by the display types.
MC68LC040 Microprocessor
The MC68LC040 microprocessor used in the PowerBook Duo 280 and 280c computers differs from the MC68030 used in earlier PowerBook Duo models in several important ways. For example, there are differences in the sizes of its caches and in the configura-
tions of its control registers. The differences make it necessary to use a different power cycling scheme with the MC68LC040. The MC68LC040 also requires new versions of the MMU tables that control the way the system addresses memory and I/O space in 24-bit and 32-bit addressing modes.
Display Driver
Support for both color and grayscale displays is provided by a display driver for the CSC (color screen controller). The display driver resides in the slot 0 declaration ROM, which is part of the system ROM on the main logic board. The driver supports grayscale, 8-bit color, and 16-bit color.
Grayscale Display
The grayscale display in the PowerBook Duo 280 and 280c computers has the
same features as the display in the PowerBook Duo 250, but the driver is different because the PowerBook Duo 280 and 280c computers use the CSC instead of the
GSC (grayscale controller).
8-Bit Color
The 8-bit-per-pixel configuration produces 256 colors. Figure 3-1 shows the color lookup table with values for sample indexes (pixels). You are advised to select colors from the first 215 entries in the color table. The values of the entries are based upon combinations of $00, $33, $66, $99, $CC, and $FF.
The last 40 entries in the table are assigned to shades of pure red, green, blue, and gray, and are based upon combinations of $00, $11, $22, $44, $55, $77, $88, $AA, $BB, and $EE. These entries are ramped and dithered to produce the various shades. Dithering, which may be implemented spatially or temporally, mixes primary colors to produce the effect of a range of different shades.
Figure 3-1 Color lookup table
The Appendix, “Color Lookup Table,” includes a table showing the color values that correspond to each of the 256 index numbers.
16-Bit Color
When the user selects 16-bit color (“Thousands”) from the Monitors control panel, the image area on the LCD display shrinks slightly, to 640 by 400 pixels, and narrow black bands appear at the top and bottom of the screen. In 16-bit color mode, the color values are stored as 5-bit R, G, and B components (only 15 bits are used). The CLUT is used as a gamma table to optimize the color values for best appearance on the color LCD.
Support for Extended DRAM
The main system controller (MSC) installed on the PowerBook Duo 280 and 280c computers’ main logic board supports up to 40 MB of self-refreshing DRAM. The computer’s hardware provides decoding for up to 32 MB of DRAM.
Note
The PowerBook Duo 280 and 280c computers support both 24-bit addressing and 32-bit addressing, but the ROM software defaults to 32-bit addressing mode. Whenever the system detects invalid PRAM, it initializes the PRAM byte to select 32-bit addressing. Making 32-bit addressing the default avoids possible confusion about memory size in a 12 MB configuration.u
Extended Power Management Capabilities
The Power Manager code, which resides in the ROM, allows you to modify the system time without affecting the battery-charging algorithm. Firmware features added for the PowerBook Duo 280 and 280c computers also support a sleep LED, version dependent code, support for a 4 A or 5 A battery, and battery conditioning.
The Power Manager section of the ROM provides a standard set of routines that developers may use (see Chapter 4, “Power Manager Interface”). All other routines
are private.
Network Support
With the PowerBook Duo 280 and 280c computers, the latest version of AppleTalk is included in both the computer’s ROM and on the System disk. The new version of AppleTalk is more efficient in remembering network settings when the computer is being docked or undocked. AppleTalk resources have been removed from the System Enabler file. The Installer application installs AppleTalk files directly into the System file when needed.
System Software
The PowerBook Duo 280 and 280c computers are shipped with system software
version 7.1.1. The system software includes a new System Enabler file, which is
required for the PowerBook Duo 280 and 280c computers.
Identifying the PowerBook Duo 280 and 280c Computers
To identify the Macintosh model it is running on, your application should use the Gestalt Manager routines described in Inside Macintosh: Overview.
The Gestalt Manager returns a gestaltMachineType value of 102 for the PowerBook Duo 280 and a value of 103 for the PowerBook Duo 280c. Those values can be used to obtain the machine name strings as described in Inside Macintosh: Overview.
Control Strip
The desktop on the PowerBook Duo 280 and 280c computers has a new status and control element called the control strip. It is a strip of graphics with small button controls and indicators in the form of various icons. Figure 3-2 shows the control strip.
Figure 3-2 Control strip
The control strip is a system extension (INIT) that provides the operating environment for control strip modules. It runs on any Macintosh computer with System 7.0 or later.
The control strip is implemented in a private layer that appears in front of the windows in all the application layers so that the windows will not obscure it. The user can move the window for the control strip to any location on the display as long as the right or left edge of the strip is attached to the right or left edge of the display.
The control strip has a tab on its unattached end. The user can drag the tab to adjust the length of the strip or hold down the Option key and drag the tab to move the strip to a new position. The user can hide the control strip, except for the tab, by clicking the tab. Clicking the tab when the control strip is hidden makes the control strip visible again. To make the control strip disappear completely, the user can click the Hide button in the control strip control panel, described on page 31.
The different parts of the control strip either display status information or act as buttons. When the user clicks a button, it is highlighted; some buttons also display additional elements such as pop-up menus.
By holding down the Option key and clicking a display area, the user can drag the display area to another position in the control strip. After the user rearranges the parts of the control strip, the new arrangment is saved when the computer is shut down and restarted.
The control strip software provides a standard screen location for a collection of individual modules that provide status and control functions. The control strip
functions include
n AppleTalk Switch: shows whether AppleTalk is on or off and lets the user
turn AppleTalk on or off without having to open the Chooser.
n Battery Monitor: displays the status of the battery or batteries.
n File Sharing: displays the state of file sharing (on, off, or users connected), lets the user turn file sharing on or off, and lets the user open the Sharing Setup control panel.
n HD Spin Down: shows whether the internal hard disk is on or off; lets the user turn off the hard disk.
n Power Settings: lets the user select between maximum conservation or maximum performance without opening the PowerBook control panel; also lets the user open the PowerBook control panel.
n Sleep Now: puts the computer into sleep mode.
n Sound Volume: lets the user select the sound volume.
n Video Mirroring: lets the user turn video mirroring on or off if an external monitor
is connected.
Note
Several of the functions of the control strip were implemented in separate control panels on earlier PowerBook models.u
Developers can add modules to the control strip. For information, see the section “Adding Control Strip Modules” beginning on page 31.
Control Panels
Several control panels are new or revised for the PowerBook Duo 280 and 280c computers. The following sections describe the new control panels.
PowerBook Setup Control Panel
The PowerBook Setup control panel controls the setup functions for the modem port configuration, SCSI disk mode, and automatic wakeup.
The PowerBook Setup control panel in the PowerBook Duo 280 and 280c computers is a modified version of the PowerBook control panel that shipped with System 7.1. It is essentially the same control panel, but with all power conservation features removed.
The PowerBook Setup control panel has been further modified to accommodate different modem configurations. The modem controls in the PowerBook Setup control panel distinguish between the Express Modem and other modems. Figure 3-3 shows the PowerBook Setup control panel with modem controls.
Figure 3-3 PowerBook Setup control panel
The PowerBook Setup control panel determines what type of modem is installed and chooses the appropriate control titles. If a modem other than the Express Modem is present, “Compatible” is changed to “Internal Modem” and “Normal” to “External Modem.” The functions associated with the radio buttons have not changed. However, the titles are different to remove the confusion generated by the incorrect use of internal/external modem when an Express Modem is installed.
If you have a third-party internal modem installed, the control titles will be Internal Modem and External Modem, and they will behave as expected, with Internal Modem selecting the modem installed in the system. These titles are the same as those used in System 7.1.
IMPORTANT
If you select Compatible, port A (Printer/Modem) is not available for serial connections. However, AppleTalk is still available.s
PowerBook Control Panel
The PowerBook control panel includes several controls that allow the user to balance performance against battery conservation. The PowerBook control panel contains the battery conservation controls, including sleep and processor cycling. It controls backlight dimming, and it can also automatically change the Power Manager configuration based on the machine’s power source.
Note
The PowerBook Duo 280 and 280c computers do not provide
the Economode reduced speed feature found on earlier
PowerBook Duo models.u
Information about power management is stored in the Preferences file in the System Folder. When the system is booted, the file is read and the contents are stored permanently in memory.
Custom and Easy Controls for Battery Conservation
The PowerBook control panel has two modes of operation. The first time you open the PowerBook control panel, you see one simple slider switch, as shown in Figure 3-5. The user may adjust the slider, as required, to improve battery conservation or system performance, or leave it in the default position.
Figure 3-4 PowerBook control panel in easy mode
When you click the Easy/Custom box in the control panel, you gain access to three additional sliders, as shown in Figure 3-5. They are System Sleeps, Hard Disk Spins Down, and Backlight Dims. If you move any of those sliders, the change will be reflected in the Better Conservation/Better Performance slider, alerting you as to whether the change improves performance or provides better conservation. The controls revert to the single slider when you toggle the Easy/Custom control again. The PowerBook control panel preserves the state in which the controls were left the last time it was used.
Figure 3-5 PowerBook control panel in custom mode
Power Conservation
There are two modes of battery conservation. One is used when the computer is plugged into AC main power, and the other is used when the computer is running on its battery. A Time Manager task installed by system extension in the PowerBook Duo file can automatically change the power management settings based on the machine environment.
When the PowerBook Duo 280 and 280c computers are shipped, the Power Conservation part of the PowerBook control panel is set with the default settings for Battery and Auto enabled, as shown in Figure 3-5. While the control panel is in easy mode, the user cannot edit those settings. When the PowerBook control panel is in custom mode, the user can enable or disable automatic conservation (Auto), select either Battery or Power Adapter as the power source, or revert to the default settings. The changes the user makes in the PowerBook panel are stored in the Preferences file.
At certain times, the PowerBook control panel compares the current Power Manager settings with both sets of parameters. It does this during open and activate events, when you switch from Manual to Auto power conservation, and when you switch to custom mode. If a match is found, the name of the matching set is displayed in the pop-up menu, and both the menu and the default button are active. If no match is found, No Set Selected is shown in the pop-up menu, and both menu and default buttons are inactive. Once a valid set is selected, No Set Selected is removed from the pop-up menu.
Control Strip Control Panel
Figure 3-6 shows the Control Strip control panel. The user can hide or show the control strip by clicking the corresponding button in the control panel.
Figure 3-6 Control Strip control panel
Adding Control Strip Modules
The control strip is implemented in software as a shell with individual control and status modules added. The control strip software draws the strip that acts as the background for the individual modules. Each module is responsible for drawing the icons and other objects that make up its user interface.
Contents of Module Files
The only required resource in a module file is a resource containing the code necessary for the module to interact with the control strip. A module file may contain more than one code resource if it is to provide multifunctional support. In that case, each module in the file is loaded and initialized separately and treated as an independent entity.
If a file contains only a single code resource, the resource may be unnamed, and the module will be referenced by its filename. If more than one module is contained within a module file, each module is required to have a unique name describing its functionality.
All other resources in a module file are optional, but there are several that are recommended in order to support a custom icon and version information. The recommended resources are
n 'BNDL'
n 'FREF'
n 'ICN#', 'icl4', 'icl8', 'ics#', 'ics4', 'ics8'
n signature resource (same type as file’s creator)
n 'vers', ID=1
Developers should confine their resources to the range 256–32767.
Module Interface
Each module’s interface to the control strip consists of a code resource of type 'sdev'. This code is responsible for performing all the functions required by the control strip as well as any functions that are custom to the module itself. The module’s entry point is at the beginning of the resource and is defined as
pascal long ControlStripModule(long message,
long params,
Rect *statusRect,
GrafPtr statusPort);
Interactions between a module and the control strip are managed by passing messages to the module to tell it what to do or to obtain information about the module and its capabilities. Each module is required to observe Pascal register saving conventions. A module may trash registers D0, D1, D2, A0, and A1, but must preserve all other registers across its call.
Field descriptions
Field descriptions
message A message number, from the list in the section “Control Strip Module Messages”, that tells the module what action to perform.
params This is the result returned by the initialize call to the module. This would typically be the handle to the module’s private variables since modules can’t have global variables. It will be passed to the module on all subsequent calls.
statusRect A pointer to a rectangle defining the area that a module may
draw within.
statusPort A pointer to the control strip’s graphics port. This will be either a color or black-and-white graphics port depending on which PowerBook model the control strip is running on.
The result value returned by the module will vary depending on the message sent to it. Results for each message are described in the sections on the individual messages.
Module Reentrancy
Any module that makes calls to routines such as GetNextEvent, ModalDialog or pop-upMenuSelect should assume that it could be called reentrantly; that is, the module could be called again while the initial call is still in progress. Situations to avoid are such things as reusing a single parameter block for multiple calls, or indiscriminately locking and unlocking your global variables around the module’s invocation.
Instead of using a single parameter block, it’s better, if possible, to allocate the parameter block on the stack. In the case of asynchronous calls, using the stack could cause problems; in that case, preventing the block’s reuse should be sufficient.
If you need to lock and unlock your global variables, it’s better to use HGetState and HLock at the beginning of the call, and HSetState at the end, so that the state is restored to what it was on entry.
Control Strip Module Reference
Control strip modules interact with the control strip software in three ways: by accepting messages, by calling utility routines, and by calling Gestalt seletors. The next three sections describe each of those interactions.
Control Strip Module Messages
All control strip modules must respond to messages from the control strip. The following messages have been defined:
Message name Message number Description
sdevInitModule 0 Initialize the module
sdevCloseModule 1 Clean up before being closed
sdevFeatures 2 Return the feature bits
sdevGetDisplayWidth 3 Return the width of the module’s display
sdevPeriodicTickle 4 Periodic tickle when nothing else
is happening
sdevDrawStatus 5 Update the interface in the control strip
sdevMouseClick 6 User has clicked on the module’s
display area
sdevSaveSettings 7 Save any changed settings in thee
module’s preferences file
sdevShowBalloonHelp 8 Display a help balloon, if the module
has one
sdevInitModule
The sdevInitModule message is the first message sent to a module after the module has been loaded from its file. Initialization allows the module to initialize its variables and to determine whether it can run on a particular machine: for example, if the module’s function is to display battery information it can run only on a PowerBook.
The module needs to load and detach any resources in the module’s resource file that will be used, because the resource file will not be kept permanently open. What that means is that your code can't use GetResource() or the like to retrieve the handle to one of the module's resources on a subsequent call. Typically you would allocate space in your global variables for handles to those detached resources.
The sdevInitModule message returns a result depending on its success at installing itself. A positive result (≥0) indicates successful installation. This result value will be passed to the module on all subsequent calls. A negative result indicates an error condition, and installation of the module is aborted by the control strip software. The module will not receive a close message when installation has been aborted.
sdevCloseModule
The sDevCloseModule message is sent to a module when it should be closed. Typically the module itself will decide when this ought to happen. When the module receives this message, it should dispose of all the detached resources it loaded as well as its global storage. No result is expected.
sdevFeatures
The sdevFeatures message queries the module for the features it supports. It returns as its result a bitmap consisting of 1 bits for supported features and 0 bits for unsupported features. All undefined bits are reserved by Apple for future features, and must be set to 0. The bits are defined as
sdevWantMouseClicks 0 If this bit is set, the control strip will notify the module of mouse down events. If this bit is not set, the control strip assumes that the module only displays status information with no user interaction.
sdevDontAutoTrack 1 If this bit is set, the control strip highlights the module’s display and then calls the module to perform mouse tracking; this bit is usually set when, for example, a module has a pop-up menu associated with it. If this bit is cleared, the control strip tracks the cursor until the mouse button is released, then sends an sdevMouseClick message to the module to notify it that there was a mouse-down event.
sdevHasCustomHelp 2 If this bit is set, the module is responsible for displaying its own help messages, which can be customized depending on its current state. If the bit is cleared, the control strip will display a generic help message when the cursor passes over the module’s display area and Balloon Help is on.
sdevKeepModuleLocked 3 If this bit is set, the module’s code will be kept locked in the heap. This bit should be set only if the module is passing the address of one of its routines to the outside world (for example, installing itself in a queue).
sdevGetDisplayWidth
The sdevGetDisplayWidth message is sent to a module to determine how much horizontal space (in pixels) its display currently requires on the control strip. The module should return the number of pixels as its result. The returned width should not be the maximum width it requires for any configuration, but should reflect how much space it currently requires, because it’s possible for a module to request that its display be resized.
IMPORTANT
You should be conservative in your use of control strip display space, which is limited. Because several modules could be requesting space, it’s possible that your module could be shoved off the end.s
sdevPeriodicTickle
The sdevPeriodicTickle message is passed to the module periodically to allow the module to update its display due to changes in its state. You should not assume any minimum or maximum interval between tickles. The module should return, as its result, some bits that signal requests for actions from the control strip software. All undefined bits in the result are reserved for future use by Apple and must be set to 0. The bits are defined as
sdevResizeDisplay 0 If this bit is set, the module needs to resize its display. The control strip sends a sdevGetDisplayWidth message to the module and then update the control strip on the display.
sdevNeedToSave 1 If this bit is set, the module needs to save changed settings to disk. The control strip software will mark the request but may defer the actual save operation to a better time (for example, when the hard disk is spinning).
sdevHelpStateChange 2 If this bit is set, the module’s state has changed so it needs to update its help message. If a help balloon is being displayed for this module, the control strip software will remove it and put up a new help balloon for the current state.
sdevCloseNow 3 If this bit is set, the module is requesting to be closed. The control strip software will call the module to save its settings, then call it again to close itself.
sdevDrawStatus
The sdevDrawStatus message indicates that the module has to redraw its display to reflect the most recent state. This message is typically sent when the user clicks on the module's display area, when any of the module’s displays is resized, or when the control strip itself needs to be updated, perhaps in response to a screen saver deactivation.
The statusRect parameter points to a rectangle bounding the module's display area, in local coordinates. All drawing done by a module within the bounds of the control strip must be limited to the module's display rectangle. The graphics port's clipRgn will be set to the visible portion of this rectangle so you can draw all the elements in the display. If you need to change the clipRgn, you should observe the initial clipRgn to avoid drawing over other items in the control strip.
sdevMouseClick
When the user clicks in a module’s display area, the control strip software calls the module with the sdevMouseClick message if the sdevWantMouseClicks bit is set in the module’s features.
If the sdevDontAutoTrack bit is also set, the control strip draws the module’s display in its highlighted state and then sends the sdevMouseClick message to the module. If the sdevDontAutoTrack bit is not set, the control strip software tracks the cursor until the mouse button is released. If the cursor is still within the module’s display area, the control strip software sends the sdevMouseClick message to notify the module that a click occurred. In either case, the module can then perform the appropriate function in response to a mouse-down event.
This message returns the same result as the sdevPeriodicTickle message.
sdevSaveSettings
The sdevSaveSettings message is passed to the module when the control strip software has determined that it’s a good time to save configuration information
to the disk. This message will be sent only if the module had previously set the sdevNeedToSave bit in the result of a sdevPeriodicTickle or sdevMouseClick message. The call returns an error code (File Manager, Resource Manager, or the like) indicating the success of the save operation. The control strip software will continue to send this message to the module until the module returns a result of 0, indicating a successful save.
sdevShowBalloonHelp
The control strip software calls the module with the sdevShowBalloonHelp message if Balloon Help is turned on, the module has previously set the sdevHasCustomHelp bit in its features, and the cursor is over the module’s display area. The module should then call the Help Manager to display a help balloon describing the current state of the module. The module should return a value of 0 if it’s successful or an appropriate error result if not.
Utility Routines
The control strip software provides a set of utility routines that are available to control strip modules. The utility routines are provided to promote a consistent user interface within the control strip and to reduce the amount of duplicated code that each module would have to include to support common functions.
The utility routines are called through a selector-based trap, _ControlStripDispatch ($AAF2). If an unimplemented routine is called, it will return paramErr as the result.
IMPORTANT
These routines should not be called at interrupt time
because they all move memory.s
SBIsControlStripVisible
You can use the SBIsControlStripVisible routine to find out whether the control strip is visible.
pascal Boolean SBIsControlStripVisible();
The SBIsControlStripVisible routine returns a Boolean value indicating whether or not the control strip is currently visible. It returns a value of true if the control strip is visible, or a value of false if it’s hidden.
It is possible for this call to return a value of true even when the control strip is not visible. That happens whenever the control strip is not accessible in the current environment. As soon as that situation changes, the control strip becomes visible again and the returned value correctly reflects the actual state.
SBShowHideControlStrip
You can use the SBShowHideControlStrip routine to show or hide the control strip.
The SBShowHideControlStrip routine determines the visibility state for the control strip based on the value of the showIt parameter. Passing a value of true makes the control strip visible, and passing a value of false hides it. Modules shouldn’t typically need to call this routine, but it’s provided as a means for other software to hide the control strip when it might get in the way.
Calling SBShowHideControlStrip with a showIt value of true may or may not show the control strip, depending on the current environment: if the control strip is not accessible, it does not become visible. If a showIt value of true is passed to this routine, then when the environment changes, the control strip will become visible.
SBSafeToAccessStartupDisk
You can use the SBSafeToAccessStartupDisk routine to find out whether the internal hard disk is spinning so that your software can determine whether to make a disk access or postpone it until a time when the disk is already spinnings.
pascal Boolean SBSafeToAccessStartupDisk();
The SBSafeToAccessStartupDisk routine returns a Boolean value of true if the disk is spinning and false if it is not.
SBOpenModuleResourceFile
You can use the SBOpenModuleResourceFile routine to open a module resource file.
pascal short SBOpenModuleResourceFile(OSType fileCreator);
The SBOpenModuleResourceFile routine opens the resource fork of the module
file whose creator is fileCreator, and return the file’s reference number as its result. If the file cannot be found or opened, SBOpenModuleResourceFile returns a result
of –1.
SBOpenModuleResourceFile provides a means for a module to load in large or infrequently used resources that it doesn’t usually need, but that it requires for a particular operation.
SBLoadPreferences
You can use the SBLoadPreferences routine to load a resource from a preferences file.
The SBLoadPreferences routine loads a resource containing a module’s configuration information from the control strip’s preferences file. The PrefsResourceName parameter points to a Pascal string containing the name of the resource. The Preferences parameter points to a variable that will hold a handle to the resource
read from the file. The handle does not need to be preallocated.
If either prefsResourceName or preferences contains a nil pointer, SBLoadPreferences does nothing and returns a result of paramErr. If the resource
is successfully loaded, it returns a result of 0. SBLoadPreferences can also return other Memory Manager and Resource Manager errors if it fails during some part of
the process.
SBSavePreferences
You can use the SBSavePreferences routine to save a resource to a preferences file.
The SBSavePreferences routine saves a resource containing a module’s configuration information to the control strip’s preferences file. The PrefsResourceName parameter points to a Pascal string containing the name of the resource. The preferences parameter contains a handle to a block of data which will be written to the file.
If either prefsResourceName or preferences has a nil value, SBSavePreferences does nothing and returns a result of paramErr. If the resource is successfully saved, SBSavePreferences returns a result of 0. SBSavePreferences can also return other Memory Manager and Resource Manager errors if it fails during some part of the process.
SBGetDetachedIndString
You can use the SBGetDetachedIndString routine to get a string from a detached resource.
The SBGetDetachedIndString routine is the detached resource version of GetIndString. The parameter theString points to a Pascal string; stringList is a handle to a detached 'STR#' resource; and whichString is the index (1–n) into the array of Pascal strings contained in the detached resource. SBGetDetachedIndString will copy the string whose index is whichString into the space pointed to by theString. If whichString is out of range, SBGetDetachedIndString will return a zero-length string.
SBGetDetachIconSuite
You can use the SBGetDetachIconSuite routine to set up a detached icon suite.
The SBGetDetachIconSuite routine creates a new icon suite, loads all of the requested icons, and then detaches the icons. The parameter theIconSuite points to the location where the handle to the icon suite will be stored; the parameter theResID is the resource ID of the icons that make up the icon suite; and the parameter selector tells which icons should be loaded into the suite. The selector parameter should typically contain one (or a combination of) the following values:
svAllLargeData 0x000000FF load large 32-by-32-pixel icons ('ICN#',
'icl4', 'icl8')
svAllSmallData 0x0000FF00 load small 16-by-16-pixel icons ('ics#',
'ics4', 'ics8')
svAllMiniData 0x00FF0000 load mini 12-by-12-pixel icons ('icm#',
'icm4', 'icm8')
These values may be OR-ed together to load combinations of icon sizes. SBGetDetachIconSuite returns an appropriate error code if it’s unsuccessful, or 0 if if was able to load the icon suite. Note that if none of the icons comprising the icon suite could be found, the call returns the error resNotFound.
IMPORTANT
You should call SBGetDetachIconSuite only when the module’s resource file is open, which is typically the case during a module’s initialization call.s
SBTrackpopupMenu
You can use the SBTrackpopupMenu routine to manage a pop-up menu.
pascal short SBTrackpopupMenu(const Rect *moduleRect,
MenuHandle theMenu);
The SBTrackpopupMenu routine handles setting up and displaying a pop-up menu associated with a module. The module should pass a pointer to its display rectangle and a handle to the menu to use. The menu will be displayed just above the module’s display rectangle, allowing the user to view the current configuration or to change the settings. SBTrackpopupMenu returns which menu item was selected, or 0 if no item was selected because the user moved the cursor outside the menu’s bounds.
IMPORTANT
Menus are displayed in the control strip’s font, so don’t use the CheckItem() routine to mark menu items, because a checkmark is supported only in the system font. Use the SetItemMark() routine instead and pass it a bullet (•).s
SBTrackSlider
You can use the SBTrackSlider routine to display and set an arbitrary parameter.
pascal short SBTrackSlider(const Rect *moduleRect,
short ticksOnSlider,
short initialValue);
The SBTrackSlider routine displays an unlabeled slider above the module’s display rectangle. You can use the slider for displaying and setting the state of an arbitrary parameter. The parameter ModuleRect contains a pointer to the module’s display rectangle; ticksOnSlider is the upper bounds of the value returned by the slider; and initialValue is the starting position (0 to ticksOnSlider–1). When the user releases the mouse button, SBTrackSlider returns the final position.
SBShowHelpString
You can use the SBShowHelpString routine to display a help balloon.
pascal OSErr SBShowHelpString(const Rect *moduleRect,
StringPtr helpString);
The SBShowHelpString routine displays a module’s help balloon. The module passes a pointer to its display rectangle and a pointer to a Pascal string, and the routine displays the balloon if possible. If the help string has a length of 0 or the Help Manager is unable to display a balloon, an error result is returned. If SBShowHelpString successfully displays the help balloon, it returns a result of 0.
SBGetBarGraphWidth
You can use the SBGetBarGraphWidth routine to find out the how wide a bar graph drawn by SBDrawBarGraph (described next) will be so that a module can calculate its display width.
pascal short SBGetBarGraphWidth(short barCount);
The SBGetBarGraphWidth routine returns the width of a bar graph containing barCount segments. If barCount has a value less than 0, the SBGetBarGraphWidth routine returns a width of 0.
SBDrawBarGraph
You can use the SBDrawBarGraph routine to draw a bar graph.
pascal void SBDrawBarGraph(short level, short barCount,
short direction,
Point barGraphTopLeft);
The SBDrawBarGraph routine draws a bar graph containing the number of segments specified by the barCount parameter in a module’s display area. If the value of barCount is less than or equal to 0, SBDrawBarGraph does nothing.
The bar graph is drawn relative to the location specified by barGraphTopLeft.
Figure 3-7 shows the way the point barGraphTopLeft determines the position of
the bar graph.
Figure 3-7 Positioning a bar graph
The level parameter determines how many segments are highlighted. The value of level should be in the range of 0 to barCount–1. If the value of level is less than 0, no segments in the bar graph are highlighted; if level is greater than or equal to barCount, all segments in the bar graph are highlighted.
The direction parameter specifies which way the bar graph will be drawn to show a larger level. It should be one of the following values:
#define BarGraphSlopeLeft -1 // max end of sloping graph is on the left
#define BarGraphFlatRight 0 // max end of flat graph is on the right
#define BarGraphSlopeRight 1 // max end of sloping graph is on the right
Figure 3-8 shows the resulting bar graph for each direction value. The arrows indicate which way an increasing level value is displayed. For sloped versions of the bar graph, the number of segments specified by the barCount value may not be larger than 8. If a larger barCount value is passed, SBDrawBarGraph draws nothing.
Figure 3-8 Direction of a bar graph
SBModalDialogInContext
You can use the SBModalDialogInContext in place of ModalDialog routine to keep background applications from getting run while your modal dialog window is visible.
The SBModalDialogInContext routine is a special version of ModalDialog that doesn’t allow background applications to get time while a modal dialog window is visible. You should use SBModalDialogInContext when you don’t want any context switching to occur.
Gestalt Selectors
The control strip software installs two Gestalt selectors to return information to the outside world. One selector returns software attributes, and the other returns the software version.
gestaltControlStripAttr
The selector gestaltControlStripAttr ('sdev') returns 32 bits describing the software attributes of this version of the control strip. Currently only the following bit
is defined:
gestaltControlStripExists 0 1=control strip is installed
gestaltControlStripVersion
The selector gestaltControlStripVersion ('sdvr') returns the version of control strip software that is installed. The format of the returned version is the same as that of the numeric part of a 'vers' resource, that is:
Bits 31-24 Major part of the version, in BCD
Bits 23-20 Minor part of the version, in BCD
Bits 19-16 Bug release version, in BCD
Bits 15- 8 Release stage:
80=final
60=beta
40=alpha
20=development
Bits 7- 0 Revision level of nonreleased version, in binary
Thus, if the software version were 1.5.3b25, the gestaltControlStripVersion selector would return $01536019.
Power Manager Interface
This chapter describes the new application programming interface (API) to the Power Manager control software. Developers who provide expanded control panel software for the PowerBook Duo 280 and 280c computers will no longer need access to the Power Manager’s internal data structures.
About the Power Manager Interface
Developers have written control panel software for previous PowerBook models that gives the user more control over the power management settings than is provided in the PowerBook control panel. Because that software reads and writes directly to the Power Manager’s private data structure and parameter RAM, the software needs to be updated any time Apple Computer makes a change to the internal operation of the Power Manager.
System software for the PowerBook 520 and 540 computers and for future PowerBook models includes interface routines for program access to the Power Manager functions, so it is no longer necessary for applications to deal directly with the Power Manager’s data structures. The new routines provide access to most of the Power Manager’s parameters. Some functions will be reserved because of their overall effect on the system. The interface is extensible; it will probably grow over time to acccommodate new kinds of functions.
Things That May Change
By using the Power Manager interface, developers can isolate themselves from future changes to the internal operation of the Power Manager software.
IMPORTANT
Apple Computer reserves the right to change the internal operation of the Power Manager software. Developers should not make their applications depend on the Power Manager’s internal data structures or parameter RAM.s
Starting with the PowerBook 520 and 540 models, developers should not depend on the Power Manager’s internal data structures staying the same. In particular, developers should beware of the following assumptions regarding different PowerBook models:
n assuming that timeout values such as the hard disk spindown time reside at the same locations in parameter RAM
n assuming that the power cycling process works the same way or uses the same parameters
n assuming that direct commands to the Power Manager microcontroller are supported on all models
Checking for Routines
Before calling any of the Power Manager interface routines, it’s always a good idea to call the Gestalt Manager to see if it they’re present on the computer. The Gestalt Manager is described in Inside Macintosh: Overview.
A new bit has been added to the gestaltPowerMgrAttr selector:
#define gestaltPMgrDispatchExists 4
If that bit is set to 1, then the routines are present.
Because more routines may be added in the future, one of the new routines simply returns the number of routines that are implemented. The following code fragment determines both that the routines in general exist and that at least the hard disk spindown routine exists.
long pmgrAttributes;
Boolean routinesExist;
routinesExist = false;
if (! Gestalt(gestaltPowerMgrAttr, &pmgrAttributes))
if (pmgrAttributes & (1<<gestaltPMgrDispatchExists))
if (PMSelectorCount() >= 7)
routinesExist = true;
sWARNING
If you call a routine that does not exist, the call to the public Power Manager trap (if the trap exists) will return an error code, which your program could misinterpret as data.s
Power Manager Interface Routines
This section tells you how to call the interface routines for the Power Manager software. The interface routines are listed here in the order of their routine selector values, as shown in Table 4-1 on page 48.
Assembly-language note:
All the routines share a single trap, _PowerMgrDispatch ($A09E). The trap is register based: parameters are passed in register D0 and sometimes also in A0. A routine selector value passed in the low word of register D0 determines which routine is executed.u

The SetSleepTimeout routine sets the amount of time the computer will wait after the last user activity before going to sleep. The value of SetSleepTimeout is expressed as the number of 15-second intervals making up the desired time. If a value of 0 is passed in, the routine sets the timeout value to the default value (currently equivalent to
8 minutes).
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for SetSleepTimeout is 3 ($03) in the low word of register D0. The sleep timeout value to set is passed in the high word of register D0.
GetHardDiskTimeout
You can use the GetHardDiskTimeout routine to find out how long the computer will wait before turning off power to the internal hard disk.
unsigned char GetHardDiskTimeout();
DESCRIPTION
The GetHardDiskTimeout routine returns the amount of time the computer will wait after the last use of a SCSI device before turning off power to the internal hard disk. The value of GetHardDiskTimeout is expressed as the number of 15-second intervals the computer will wait before turning off power to the internal hard disk.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for GetHardDiskTimeout is 4 ($04) in the low word of register D0. The hard
disk timeout value is returned in the low word of register D0.
SetHardDiskTimeout
You can use the SetHardDiskTimeout routine to set how long the computer will wait before turning off power to the internal hard disk.
void SetHardDiskTimeout(unsigned char timeout);
DESCRIPTION
The SetHardDiskTimeout routine sets how long the computer will wait after the last use of a SCSI device before turning off power to the internal hard disk. The value of SetHardDiskTimeout is expressed as the number of 15-second intervals the computer will wait before turning off power to the internal hard disk. If a value of 0 is passed in, the routine sets the timeout value to the default value (currently equivalent to 4 minutes).
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for SetHardDiskTimeout is 5 ($05) in the low word of register D0. The hard
disk timeout value to set is passed in the high word of register D0.
HardDiskPowered
You can use the HardDiskPowered routine to find out whether the internal hard disk
is on.
Boolean HardDiskPowered();
DESCRIPTION
The HardDiskPowered routine returns a Boolean value indicating whether or not the internal hard disk is powered up. A value of true means that the hard disk is on, and a value of false means that the hard disk is off.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for HardDiskPowered is 6 ($06) in the low word of register D0. The Boolean result is returned in the low word of register D0.
SpinDownHardDisk
You can use the SpinDownHardDisk routine to force the hard disk to spin down.
void SpinDownHardDisk();
DESCRIPTION
The SpinDownHardDisk routine immediately forces the hard disk to spin down and power off if it was previously spinning. Calling SpinDownHardDisk will not spin down the hard disk if spindown is disabled by calling SetSpindownDisable (defined later in this section).
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for SpinDownHardDisk is 7 ($07) in the low word of register D0.
IsSpindownDisabled
You can use the IsSpindownDisabled routine to find out whether hard disk spindown is enabled.
Boolean IsSpindownDisabled();
DESCRIPTION
The IsSpindownDisabled routine returns a Boolean true if hard disk spindown is disabled, or false if spindown is enabled.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for IsSpindownDisabled is 8 ($08) in the low word of register D0. The Boolean result is passed in the low byte of register D0.
SetSpindownDisable
You can use the SetSpindownDisable routine to disable hard disk spindown.
void SetSpindownDisable(Boolean setDisable);
DESCRIPTION
The SetSpindownDisable routine enables or disables hard disk spindown, depending on the value of setDisable. If the value of setDisable is true, hard disk spindown will be disabled; if the value is false, spindown will be enabled.
Disabling hard disk spindown affects the SpinDownHardDisk routine, defined earlier, as well as the normal spindown that occurs after a period of hard disk inactivity.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for SetSpindownDisable is 9 ($09) in the low word of register D0. The Boolean
value to set is passed in the high word of register D0.
HardDiskQInstall
You can use the HardDiskQInstall routine to notify your software when power to the internal hard disk is about to be turned off.
The HardDiskQInstall routine installs an element into the hard disk power down queue to provide notification to your software when the internal hard disk is about to
be powered off. For example, this feature might be used by the driver for an external battery-powered hard disk. When power to the internal hard disk is turned off, the external hard disk could be turned off as well.
short hdQType; /* queue element type (must be HDQType) */
short hdFlags; /* miscellaneous flags (reserved) */
HDSpindownProc hdProc; /* pointer to routine to call */
long hdUser; /* user-defined (variable storage, etc.) */
} HDQueueElement;
When power to the internal hard disk is about to be turned off, the software calls the routine pointed to by the hdProc field so that it can do any special processing. The routine will be passed a pointer to its queue element so that, for example, the routine can reference its variables.
Before calling HardDiskQInstall, the calling program must set the hdQType field to
#define HDPwrQType 'HD' /* queue element type */
or the queue element won’t be added to the queue and HardDiskQInstall will return an error.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for HardDiskQInstall is 10 ($0A) in the low word of register D0. The pointer to the HDQueue element is passed in register A0. The result code is returned in the low word of register D0.
HardDiskQRemove
You can use the HardDiskQRemove routine to discontinue notification of your software when power to the internal hard disk is about to be turned off.
The HardDiskQRemove routine removes a queue element installed by HardDiskQInstall. If the hdQType field of the queue element is not set to HDPwrQType, HardDiskQRemove simply returns an error.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for HardDiskQRemove is 11 ($0B) in the low word of register D0. The pointer to the HDQueue element is passed in register A0. The result code is returned in the low word of register D0.
GetScaledBatteryInfo
You can use the GetScaledBatteryInfo routine to find out the condition of the battery or batteries .
The GetScaledBatteryInfo routine provides a generic means of returning information about the battery or batteries in the system. Instead of returning a voltage value, the routine returns the battery level as a fraction of the total possible voltage.
Note
New battery technologies such as NiCad (nickel cadmium) and nickel metal hydride (NiMH) have replaced the sealed lead acid batteries of the original Macintosh Portable. The algorithm for determining the battery voltage that is documented in the Power Manager chapter of Inside Macintosh, Volume VI, is no longer correct for all PowerBook models.u
The value of whichBattery determines whether GetScaledBatteryInfo returns information about a particular battery or about the total battery level. The value of GetScaledBatteryInfo should be in the range of 0 to BatteryCount(). If the value of whichBattery is 0, GetScaledBatteryInfo returns a summation of all the batteries, that is, the effective battery level of the whole system. If the value of whichBattery is out of range, or the selected battery is not installed, GetScaledBatteryInfo will return a result of 0 in all fields. Here is a summary of the effects of the whichBattery parameter:
Value of whichBattery Information returned
0 Total battery level for all batteries
From 1 to BatteryCount() Battery level for the selected battery
Less than 0 or greater than BatteryCount 0 in all fields of theInfo
The GetScaledBatteryInfo routine returns information about the battery in the following data structure:
The flags character contains several bits that describe the battery and charger state. If a bit value is 1, that feature is available or is operating; if the bit value is 0, that feature is not operating. Unused bits are reserved by Apple for future expansion.
Field descriptions
Bit
Bit name number Description
batteryInstalled 7 A battery is installed.
batteryCharging 6 The battery is charging.
chargerConnected 5 The charger is connected.
The value of warningLevel is the battery level at which the first low battery warning message will appear. The routine returns a value of 0 in some cases when it’s not appropriate to return the warning level.
The value of batteryLevel is the current level of the battery. A value of 0 represents the voltage at which the Power Manager will force the computer into sleep mode; a value of 255 represents the highest possible voltage.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for GetScaledBatteryInfo is 12 ($0C) in the low word of register D0. The BatteryInfo data are returned in the low word of register D0 as follows:Bits 31–24 Flags
Bits 23–16 Warning level
Bits 15–8 Reserved
Bits 7–0 Battery level
AutoSleepControl
You can use the AutoSleepControl routine to turn the automatic sleep feature on
and off.
void AutoSleepControl(Boolean enableSleep);
DESCRIPTION
The AutoSleepControl routine enables or disables the automatic sleep feature that causes the computer to go into sleep mode after a preset period of time. When enableSleep is set to true, the automatic sleep feature is enabled (this is the normal state). When enableSleep is set to false, the computer will not go into the sleep mode unless it is forced to either by some user action—for example, by the user’s selecting Sleep from the Special menu of the Finder—or in a low battery situation.
IMPORTANT
Calling AutoSleepControl with enableSleep set to false multiple times increments the auto sleep disable level so that it requires the same number of calls to AutoSleepControl with enableSleep set to true to reenable the auto sleep feature. If more than one piece of software makes this call, auto sleep may not be reenabled when you think it should be.s
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for AutoSleepControl is 13 ($0D) in the low word of register D0. The Boolean value is passed in the high word of register D0.
GetIntModemInfo
You can use the GetIntModemInfo routine to find out information about the
internal modem.
unsigned long GetIntModemInfo();
DESCRIPTION
The GetIntModemInfo routine returns a 32-bit field containing information that describes the features and state of the internal modem. It can be called whether or not
a modem is installed and will return the correct information.
If a bit is set, that feature or state is supported or selected; if the bit is cleared, that feature is not supported or selected. Undefined bits are reserved by Apple for future expansion.
Field descriptions
Bit
Bit name number Description
hasInternalModem 0 An internal modem is installed.
intModemRingDetect 1 The modem has detected a ring on the telephone line.
intModemOffHook 2 The internal modem has taken the telephone line
off hook (that is, you can hear the dial tone or
modem carrier).
intModemRingWakeEnb 3 The computer will come out of sleep mode if the modem detects a ring on the telephone line and
the computer supports this feature (see the canWakeupOnRing bit in PMFeatures).
extModemSelected 4 The external modem is selected (if this bit is set, then the modem port will be connected to port A of the SCC; if the modem port is not shared by the internal modem and the SCC, then this bit can be ignored).
Bits 15–31 contain the modem type, which will take on one of the following values: –1 Modem is installed but type not recognized.
0 No modem is installed.
1 Modem is a serial modem.
2 Modem is a PowerBook Duo–style Express Modem.
3 Modem is a PowerBook 160/180–style Express Modem.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for GetIntModemInfo is 14 ($0E) in the low word of register D0. The bit field to set is passed in the high word of register D0.
SetIntModemState
You can use the SetIntModemState routine to set some parts of the state of the internal modem.
void SetIntModemState(short theState);
DESCRIPTION
The SetIntModemState routine configures some of the internal modem’s state information. Currently the only items that can be changed are the internal/external modem selection and the wakeup-on-ring feature.
To change an item of state information, the calling program sets the corresponding bit in theState. In other words, to change the internal/external modem setting, set bit 4 of theState to 1. To select the internal modem, bit 15 should be set to 0; to select the external modem, bit 15 should be set to 1.Using this method, the bits may be set or cleared independently, but they may not be set to different states at the same time.
Note
In some PowerBook computers, there is a hardware switch to connect either port A of the SCC or the internal modem to the modem port. The two are physically separated, but software emulates the serial port interface for those applications that don’t use the Communications Toolbox. You can check the hasSharedModemPort bit returned by PMFeatures to determine which way the computer is set up.u
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for SetIntModemState is 15 ($0F) in the low word of register D0. The bit field is returned in register D0.
MaximumProcessorSpeed
You can use the MaximumProcessorSpeed routine to find out the maximum speed of the computer’s microprocessor.

CurrentProcessorSpeed
You can use the CurrentProcessorSpeed routine to find out the current clock speed of the microprocessor.
short CurrentProcessorSpeed();
DESCRIPTION
The CurrentProcessorSpeed routine returns the current clock speed of the computer’s microprocessor, in MHz. The value returned will be different from
the maximum processor speed if the computer has been configured to run with a reduced processor speed to conserve power.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for CurrentProcessorSpeed is 17 ($11) in the low word of register D0. The
processor speed value is returned in the low word of register D0.
FullProcessorSpeed
You can use the FullProcessorSpeed routine to find out whether the computer will run at full speed the next time it restarts.
Boolean FullProcessorSpeed();
DESCRIPTION
The FullProcessorSpeed routine returns a Boolean value of true if, on the next restart, the computer will start up at its maximum processor speed; it returns false if the computer will start up at its reduced processor speed.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for FullProcessorSpeed is 18 ($12) in the low word of register D0. The Boolean
result is returned in the low byte of register D0.
SetProcessorSpeed
You can use the SetProcessorSpeed routine to set the clock speed the microprocessor will use the next time it is restarted.
Boolean SetProcessorSpeed(Boolean fullSpeed);
DESCRIPTION
The SetProcessorSpeed routine sets the processor speed that the computer will use the next time it is restarted. If the value of fullSpeed is set to true, the processor will start up at its full speed (the speed returned by MaximumProcessorSpeed, described on page 59). If the value of fullSpeed is set to false, the processor will start up at its reduced speed.
For PowerBook models that support changing the processor speed dynamically, the processor speed will also be changed. If the speed is actually changed, SetProcessorSpeed will return true; if the speed isn’t changed, it will return false.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for SetProcessorSpeed is 19 ($13) in the low word of register D0. The Boolean value to set is passed in the high word of register D0. The Boolean result is returned in register D0.

is 22 ($16) in the low word of register D0. The pointer to WakeupTime is passed in register A0.
SetWakeupTimer
You can use the SetWakeupTimer routine to set the time when the computer will wake up from sleep mode.
void SetWakeupTimer(WakeupTime *theTime);
DESCRIPTION
The SetWakeupTimer routine sets the time when the computer will wake up from sleep mode and enables or disables the timer. On a PowerBook model that doesn’t support the wakeup timer, SetWakeupTimer does nothing.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for SetWakeupTimer
is 23 ($17) in the low word of register D0. The pointer to WakeupTime is passed in register A0.
IsProcessorCyclingEnabled
You can use the IsProcessorCyclingEnabled routine to find out whether processor cycling is enabled.
Boolean IsProcessorCyclingEnabled();
DESCRIPTION
The IsProcessorCyclingEnabled routine returns a Boolean value of true if processor cycling is currently enabled, or false if it is disabled.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for IsProcessorCyclingEnabled is 24 ($18) in the low word of register D0.
The Boolean result is returned in register D0.
EnableProcessorCycling
You can use the EnableProcessorCycling routine to turn the processor cycling feature on and off.
void EnableProcessorCycling(Boolean enable);
DESCRIPTION
The EnableProcessorCycling routine enables processor cycling if a value of true is passed in, and disables it if false is passed.
sWARNING
You should follow the advice of the mustProcessorCycle bit in the feature flags when turning processor cycling off. Turning processor cycling off when it’s not recommended can result in hardware failures due to overheating.s
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for EnableProcessorCycling is 25 ($19) in the low word of register D0.
The Boolean value to set is passed in the high word of register D0.
BatteryCount
You can use the BatteryCount routine to find out how many batteries the
computer supports.
short BatteryCount();
DESCRIPTION
The BatteryCount routine returns the number of batteries that are supported internally by the computer. The value of BatteryCount returned may not be the
same as the number of batteries currently installed.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for BatteryCount is 26 ($1A) in the low word of register D0. The number of batteries supported is returned in the low word of register D0.
GetBatteryVoltage

Fixed GetBatteryVoltage(short whichBattery);
DESCRIPTION
The GetBatteryVoltage routine returns the battery voltage as a fixed-point number.
The value of whichBattery should be in the range 0 to BatteryCount()–1. If the value of whichBattery is out of range, or the selected battery is not installed, GetBatteryVoltage will return a result of 0.0 volts.
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for GetBatteryVoltage is 27 ($1B) in the low word of register D0. The battery
number is passed in the high word of register D0. The 32-bit value of the battery
voltage is returned in register D0.
GetBatteryTimes
You can use the GetBatteryTimes routine to find out about how much battery
The GetBatteryTimes routine returns information about the time remaining on
the computer’s battery or batteries. The information returned has the following
data structure:
typedef struct BatteryTimeRec {
unsigned long expectedBatteryTime; /* estimated time remaining */
unsigned long minimumBatteryTime; /* minimum time remaining */
unsigned long maximumBatteryTime; /* maximum time remaining */
unsigned long timeUntilCharged; /* time until full charge */
} BatteryTimeRec;
The time values are in seconds. The value of expectedBatteryTime is the estimated time remaining based on current usage patterns. The values of minimumBatteryTime and maximumBatteryTime are worst-case and best-case estimates, respectively. The value of timeUntilCharged is the time that remains until the battery or batteries are fully charged.
The value of whichBattery determines whether GetBatteryTimes returns the time information about a particular battery or the total time for all batteries. The value of GetScaledBatteryInfo should be in the range of 0 to BatteryCount(). If the value of whichBattery is 0, GetBatteryTimes returns a total time for all the batteries, that is, the effective battery time for the whole system. If the value of whichBattery is out of range, or the selected battery is not installed, GetBatteryTimes will return a result of 0 in all fields. Here is a summary of the effects of the whichBattery parameter:
Value of whichBattery Information returned
0 Total battery time for all batteries
From 1 to BatteryCount( ) Battery time for the selected battery
Less than 0 or greater than BatteryCount 0 in all fields of theTimes
ASSEMBLY-LANGUAGE INFORMATION
The trap is _PowerMgrDispatch ($A09E). The selector value for GetBatteryTimes is 28 ($1C) in the low word of register D0. The pointer to BatteryTimeRec is passed in register A0.
Header File for Power Manager Dispatch
Here is a sample header file for access to the Power Manager.
This appendix contains more information about the color lookup table used in the PowerBook Duo 280 and 280c computers. Table A-1 shows the color values for each index. Index numbers are shown in hexadecimal ($0000) and decimal (0). Red (R), green (G), and blue (B) color values are shown in hexadecimal ($0000).
The first 215 entries are combinations, made up of R, G, and B values of $0000, $3333, $6666, $9999, $CCCC, and $FFFF. You should generally select colors from those 215 entries of the CLUT.
The last 40 entries are assigned to red ramp, green ramp, blue ramp, and gray scale. The values of those last 40 entries can be dithered, either spatially or temporally, to simluate the appearance of intermediate colors. Each colored ramp consists of a single color with values of $0000, $1111, $2222, $4444, $5555, $7777, $8888, $AAAA, $BBBB, $DDDD, and $EEEE. The gray ramp has those same values in all three color channels
