OS/2 2.1 Power 9100 Display Drivers
Version 1.10.10 BETA
11/11/94
Driver Features:
----------------
This driver supports the following features:
1) PCI/VL-Bus Auto Detection.
2) 8, 16 and 32 Bits Per Pixel.
3) IBM 525 RAMDAC support.
4) Brooktree 485 RAMDAC support.
5) Auto-Resolution correction based on display mode being requested and
amount of VRAM available.
6) Auto Display Refresh Rate correction based on the capabilities of the
RAMDAC on the installed adapter. For example, if 1600x1200 8 Bpp mode
is selected on an adapter which uses a Bt485 RAMDAC 135MHz, the driver will
not allow this mode to be set since the DAC does not support this mode.
Instead, it will display a warning message.
DO NOT try to install for this mode. It may damage your adapter.
7) OS/2 Windowed Sessions.
8) DOS Windowed Sessions.
9) Full screen OS/2 sessions.
10) Full screen Dos sessions.
11) Power 9100 Full screen Windows sessions.
12) Power 9100 Seamless Windows sessions.
13) Resolution and color depth switching without having to reinstall the
drivers.
14) Configurable display refresh rates.
15) After the drivers have been installed and enabled by restarting the
system, the configuration utility will display only the color depths
and resolution modes supported by the installed adapter.
16) 1, 2 and 4 Megabyte VRAM support.
Mode Support
------------
The following display resolution modes are supported by this driver:
NOTE: Take into consideration the amount of memory on your
video card. Some of the modes supplied are NOT
supported if the card has only 2MB of video memory.

1280x1024 2/4MB 4MB ONLY 4MB ONLY
*1600x1200 2/4MB 4MB ONLY
* - IBM DAC ONLY
Driver Installation Procedures:
------------------------------
The diskette must have the correct volume label in order for the install
program to function correctly. The correct volume label is:
P91DRV 1
The space is required. You can apply the volume label to the disk by
typing the following from an OS/2 command prompt:
label x: [Enter]
P91DRV 1 [Enter]
Where x is the drive letter of the floppy drive containing the Power
9100 driver disk. For example, if the floppy drive with the Power
9100 driver disk was drive A, you would type:
label a: [Enter]
P91DRV 1 [Enter]
Driver installation is initiated by running the INSTALL.CMD batch file
from the installation diskette. This batch file copies installation files
to the OS/2 installation directory and executes the OS/2 DSPINSTL program
from the hard drive.
The OS/2 driver installation program installs both the OS/2 drivers and the
Windows drivers. Do not perform a separate installation of the Windows
drivers as described in the Windows drivers release notes. To do so can
cause problems; for example, Seamless Windows support may no longer work,
and the version of Full Screen Windows drivers may not be compatible with
Full Screen WIN-OS2.
1) Bring up OS/2 as you would normally. (VGA driver should be installed.)
2) Make sure you have closed any Windows Full Screen and Seamless Windows
sessions.
3) Insert the Power 9100 OS/2 distribution diskette into either drive A:
or drive B:.
4) Select either an OS/2 Window or OS/2 Full Screen session from the
"Command Prompts" folder.
5) Select the diskette drive you are using by typing either A: or B: and
[Enter].
6) To start the installation, type
install <bootdrive>:
Where <bootdrive> is the letter of the drive where OS/2 is installed
and started from. For example, if you have installed OS/2 on drive
C: then you would issue the command
install c:
7) In the "Display Driver Install" dialog box, select
Primary Display
and click on the OK button.
8) In the "Display Adapter Type" dialog box, select
Power 9100 Display Driver
and click on the OK button.
9) In the "Source Directory" dialog box, ensure that the drive indicated
is the drive the installation diskette is in. Change it if necessary.
Click on the Install button.
The installation utility copies files into the appropriate directories
and modifies the CONFIG.SYS, SYSTEM.INI, and OS2.INI files.
10) When the file have been copied, the Power 9100 Configuration Utility
dialog box will be displayed. You may now select the specific driver
configuration that you would like to run. You do this by making
selections in the Monitor, Color Depth, Resolution, Refresh Rate and
Resource Size list boxes. After you have specified the desired
configuration, click on the Save button.
The Power 9100 Configuration Utility saves the configuration information
in the OS2.INI file. It also creates a "Weitek Display Driver Utilities"
folder on the OS/2 desktop. This folder contains utilities for
configuring the Power 9100 OS/2 display driver as well as the Power 9100
Full Screen Windows display driver.
The Full Screen Windows drivers are installed using the default
configuration of 640x480 8 bits per pixel configuration. Upon restarting
OS/2 you may change this configuration by running the Power 9100 Full
Screen Windows display driver configuration utility from the "Weitek
Display Driver Utilities" folder.
Note: Your hardware may not support all of the displayed color depths
and resolutions. If you are unsure of whether a specific
configuration is supported by your hardware, select cancel
and the proceed to step 11. This will install the default
configuration of 640x480 8 bits per pixel. Upon restarting
OS/2, follow the procedures in the "Changing Power 9100 OS/2 Driver
Configuration" section.
11) The "Display Driver Install" dialog box informs you that changes have
been made to your system configuration and you must shut down your
system. Click on the OK button.
12) Remove the distribution diskette from the diskette drive.
13) Shut down the system by selecting Shut Down from the OS/2 desktop
menu.
14) Press Ctrl/Alt/Delete.
15) Restart OS/2. The selected driver configuration is now installed
and running.
Changing Power 9100 OS/2 Driver Configuration:
---------------------------------------------
1) Run the Power 9100 OS/2 Driver Configuration Utility from the "Weitek
Display Driver Utilities" folder.
2) Select the appropriate monitor from the "Monitor Type" list box.
3) Select the desired color depth from the "Color Depth" list box.
4) Select the desired resolution from the "Resolution" list box.
5) Select the desired refresh rate from the "Refresh Rate" list box.
6) Select the desired icon resource size from the "Resource Size" list box.
7) After making all the desired changes to the driver configuration, click
the Save button. The driver configuration information will be updated and
the utility will close. In order for the changes to take effect you will
have to shut down your system and restart OS/2.
8) Clicking on the Reset button will reset the configuration parameters to
the current driver configuration.
9) Clicking on the Cancel button will close the configuration utility
without making any changes to the current driver configuration.
Removing the Power 9100 Drivers
-------------------------------
1) Make sure you have closed any Windows Full Screen and Seamless Windows
sessions.
2) Insert the Power 9100 OS/2 distribution diskette into either drive A:
or drive B:.
3) Select either an OS/2 Window or OS/2 Full Screen session from the
"Command Prompts" folder.

Known Limitations
-----------------
There are issues with OS/2 2.11 (OS/2 2.1 with OS/2 Corrective Services
Diskettes XR06200), and 32-bits-per-pixel (32 bpp) modes. These issues will
appear in OS/2 applications that display bitmaps, such as OS/2 Chess. In
32 bpp mode, the chess pieces will appear clear. You may also see black
icons on the OS/2 desktop. These are issues with OS/2 2.11, as the problems
do not appear with the retail copy of OS/2 2.1. Any issues in 32 bpp mode
with OS/2 2.11 should be verified on OS/2 2.1 to determine if the problem
is caused by OS/2 2.11 or the Power 9100 drivers.
Multimedia Presentation Manager/2 (MMPM/2) has issues with 16 bpp modes that
are corrected in the OS/2 Corrective Services Diskettes XR06200. It is
recommended that the Corrective Services Diskettes for MMPM/2 be applied to
resolve this problem.
Multimedia Presentation Manager/2 (MMPM/2) currently does not support 32 bpp
modes.
During program load from the desktop, the colors of the icons on the desktop
may change colors, or the entire screen may change colors. Some programs
supply their own color palette which overrides OS/2's color palette. The
desktop should return to normal when the application is closed, or by
performing an action (such as opening or closing a folder) that refreshes the
screen.
Special Note to VL-Bus Users
----------------------------
The Power 9100 chip requires a 4MB address space to function correctly.
The start location of this 4MB range is controlled by the wBase= line in
the P9X00RES.DAT file, which is normally located in the \OS2\POWER_9K (for OS/2
support) and \OS2\MDOS\WINOS2 (for WinOS2 support) directories, and by the
MemAddr= line in the P9X00RES.INI file in \OS2\MDOS\WINOS2 directory.
The default memory base address is 80000000h. Not all VL-Bus motherboards
support this default memory base address. If you get a black screen after
installing these drivers and rebooting, follow the instructions on page 338
of the "Using the Operating System" manual for "Recovering from an Incorrect
Display Type Selection" to return to VGA. Remove the Power 9100 drivers as
outlined in the section above. Shut down OS/2, restart, then reinstall the
Power 9100 drivers. However, before shutting down after the install, edit the
P9X00RES.DAT files in the \OS2\POWER_9K and \OS2\MDOS\WINOS2 directories.
Look for the line that reads:
wBase = 80
Change this to one of the following options:
wBase = 20
wBase = 40
wBase = 60
wBase = 90
wBase = A0
wBase = B0
wBase = C0
wBase = D0
Try each until you find one that brings up OS/2. Then, look for the following
line in the P9X00RES.INI file in \OS2\MDOS\WINOS2:
MemAddr=8000
If you selected wBase = 20 in P9X00RES.DAT, change the line to read:
MemAddr=2000
If you selected wBase = 40 in P9X00RES.DAT, change the line to read:
MemAddr=4000
If you selected wBase = 60 in P9X00RES.DAT, change the line to read:
MemAddr=6000
If you selected wBase = 90 in P9X00RES.DAT, change the line to read:
MemAddr=9000
If you selected wBase = A0 in P9X00RES.DAT, change the line to read:
MemAddr=A000
If you selected wBase = B0 in P9X00RES.DAT, change the line to read:
MemAddr=B000
If you selected wBase = C0 in P9X00RES.DAT, change the line to read:
MemAddr=C000
If you selected wBase = D0 in P9X00RES.DAT, change the line to read:
MemAddr=D000
