- Configuring installation hardware
-
- UnixWare 7 automatically determines the correct hardware settings for
- EISA, MCA, and PCI hardware devices needed to install the system. If you
- have an ISA device, or the devices in your system have hardware conflicts
- such as duplicate interrupt vectors, you need to enter the Device
- Configuration Utility (DCU) by selecting Run the DCU interactively during
- the installation.
-
- You can also enter the DCU after installing your system, to add
- additional hardware devices not needed by the installation. See Chapter
- 7, ``Adding or removing hard disks, tapes, and other devices'' for more
- information.
- _________________________________________________________________________
-
- NOTE UnixWare 7 provides several other hardware configuration
- managers to configure network, modem, print, audio, and video
- devices after you install the system. See ``Configuring additional
- hardware'' for a complete list.
- _________________________________________________________________________
-
- Navigating the DCU is comparable to navigating the installation windows,
- with similar cursor movement, text entry, and help keys active.
-
- From within the DCU, you can:
-
- + View hardware device configuration, to view all detected and
- configured hardware on your system.
-
- + Modify hardware device configuration, to resolve interrupt, I/O, and
- memory conflicts between devices.
-
- + Activate a software device driver needed by your hardware device.
-
- + Configure a software device driver to support the hardware.
- _________________________________________________________________________
-
- NOTE You can only make changes with the DCU once during the
- installation. If you apply changes and exit the DCU, then realize
- you need to make more changes, you must re-start the installation.
- _________________________________________________________________________
-
- Viewing hardware device configuration
-
- To view the currently detected hardware on your system, select Hardware
- Device Configuration from the DCU main menu. The Hardware Device
- Configuration window appears. This window displays hardware parameters
- for each device configured on your system. If a value is not needed, a
- dash appears in its place.
-
- The fields shown are:
-
- ``Configuration Status'' Indicates whether or not the hardware
- controller will (Y) or will not (N) be
- configured into the kernel.
-
- ``Device Name'' Displays the name of the device. If a driver is
- assigned to an entry, the entry will be either
- the device name such as COM Port, or a driver
- name such as asyc, the driver for the COM port.
-
- If the device name is UNKNOWN on an EISA, MCA
- or PCI system, this is an entry from NVRAM
- (Non-Volatile Random Access Memory) indicating
- that the DCU cannot assign a driver name. For
- example, if you have installed a network
- adapter, but have not installed the
- corresponding software for the adapter, it will
- be listed as UNKNOWN.
-
- If the device name is unused, this indicates
- that an ISA driver is disabled, but the device
- parameters are retained.
-
- ``IRQ'' Specifies the interrupt request vector (IRQ)
- value for the hardware controller.
-
- ``IOStart, IOend'' Lists the start and end addresses, in
- hexadecimal notation, for the controller's I/O
- address range.
-
- ``Memstart, MemEnd'' Lists the start and end addresses, in
- hexadecimal notation, for the hardware
- controller's memory address range.
-
- For an HBA controller, these are the start and
- end addresses of the BIOS for the controller.
-
- ``DMA'' Lists the DMA channel for the controller.
-
- To view additional information about any of the entries, use the arrow
- keys to highlight the desired controller and press <F6>. When you do, you
- see configuration information for the following advanced parameters:
-
- ``Unit'' The unit number for a controller which supports
- multiple devices.
-
- ``IPL'' The interrupt priority level, for those devices
- which have priority handling capability.
-
- ``ITYPE'' The IRQ sharing type.
-
- ``BindCPU'' The CPU to which the device binds.
-
- Additional information about these parameters is described in the
- ``Installation hardware checklist''.
-
-
- Modifying hardware device configuration
-
- To change a device driver parameter for a device:
-
- 1. Select Hardware Device Configuration from the DCU main menu. The
- Hardware Device Configuration window appears.
-
- 2. Move the cursor to the field for the parameter you want to change.
-
- To change an advanced parameter, first bring up the advanced window
- by highlighting the desired driver and pressing <F6>.
-
- 3. Change the parameter in one of these ways:
-
- + Directly entering text.
-
- + Pressing <F2> to toggle between available choices. When the
- desired choice is visible, press <Enter>.
-
- + Pressing <F2> to bring up a selection list and highlighting the
- desired choice. When the desired choice is visible, press
- <Enter>.
-
- Continue changing values until you have removed any duplicate or
- overlapping IRQ, I/O, or memory addresses.
- _______________________________________________________________________
-
- NOTE Exceptions to this rule are those devices that can share
- interrupt vectors. These devices must be configured to have the
- appropriate ITYPE and IPL values, or the system may not boot
- correctly.
- _______________________________________________________________________
- _______________________________________________________________________
-
- NOTE Do not change entries for the keyboard. Doing so may
- impair the operation of your system.

-
-
- 4. To return to the DCU main menu, press <F10>.
-
- 5. If necessary, view and activate software device drivers and add a new
- controller.
-
- 6. When you have finished making all changes with the DCU, select Apply
- Changes & Exit DCU to save your changes.
-
-
- Viewing and activating software device drivers
-
- The following procedures allow you to view or activate the device drivers
- currently installed on your system.
-
- 1. From the DCU main menu, select Software Device Drivers.
-
- 2. Select a device driver category. If you are unsure which category the
- desired device driver is in, select All Software Device Drivers.
-
- The Software Device Drivers window for the selected class of device
- drivers is displayed. The window contains three fields:
-
- ``Active/Inactive'' If an asterisk (*) appears in this
- field, the driver is available for
- use assuming the hardware it supports
- is installed and enabled. If the
- field is empty, the device driver is
- inactive and supports no devices.
-
- ``Driver'' Lists the device driver name.
-
- ``Names of Supported Devices'' Lists the hardware controllers the
- device driver supports (if
- available).
-
- Many device drivers support multiple controllers. The Software Device
- Drivers window lists the controllers supported by each device driver.
- If a device driver is inactive, the UnixWare system cannot access any
- of the controllers that the device driver supports.
-
- 3. To view a specific device driver, move the cursor to it and press
- <F6>. Information about the driver appears. For a description of the
- fields, see ``Modifying hardware device configuration''.
-
- Press <Enter> to return to the Software Device Drivers window.

- that supports this controller must be active.
- _______________________________________________________________________
-
- 5. If you are an experienced administrator who is installing the
- UnixWare 7 system, and if there are device drivers on your HBA
- diskettes that you are sure will not be needed on your system, you
- can instruct the installation software not to install these device
- drivers. To do so, remove the asterisk next to each of these device
- drivers.
-
- 6. To apply the changes and return to the Software Device Drivers
- window, press <F10>, then press <Enter>.

- Configuring PC Card (PCMCIA) modems
-
- The Network Configuration Manager configures most networking hardware
- devices. However, one special type of modem -- the PC Card (PCMCIA) modem
- used on some laptop computers -- is configured within the DCU.
-
- PC Card modems are enabled by the pcic driver when the system boots up,
- and are controlled by the asyc driver while in use. To configure a PC
- Card modem you should first enable the pcic driver, and then create a new
- asyc entry.
-
- Enabling the pcic driver
-
-
- 1. Enter the Device Configuration Utility.
-
- 2. Select Software Device Drivers from the DCU main menu.
-
- 3. Select Miscellaneous from the Software Device Drivers Selection menu.
-
- 4. Enable the pcic entry if it is not already selected. If an asterisk
- does not appear next to the pcic entry, move the cursor to the pcic
- entry and press <Space>.
-
- 5. Press <F5> to create an instance of the pcic driver.
-
- 6. If necessary, modify the default memory range (MemStart and MemEnd).
-
- The pcic driver requires an 8KB memory window. The D0000-D1FFF memory
- range is often available on laptop computers.
-
- 7. Press <F10> to enable the pcic driver and return to the Software
- Device Drivers window.
-
- 8. Press <Enter> to return to the Software Device Driver Selections
- menu.

- it is not already enabled.
-
- 11. Press <F5> to create a new instance of the asyc driver.
-
- 12. Specify this as a PC Card entry by entering 20 in the ``Unit'' field.
-
- 13. Change the default IRQ value to an available IRQ.
-
- You can use IRQ 3 on most laptops.
-
- 14. Change the I/O address range (IOStart and IOend) to an unused I/O
- address range.
-
- On most laptops, the I/O address range 2f8-2ff is available. Set
- IOStart to 2f8 and IOend to 2ff.
-
- 15. Press <F10> to create the new asyc entry and return to the "Software
- Device Drivers" screen.
