Descriptions:
-------------
( The following descriptions assume that OS/2 2.0 is installed on
the target system, drive C:. )
The file W800.DLL is a customized PM display driver which supports
the 800x600-16 color mode PM Desktop session. This file (if 800x600 16
color mode is chosen as the desired display mode) will replace the default
DISPLAY.DLL (640x480-16 color standard VGA mode) file in directory
C:\OS2\DLL. This driver is fully compatible with 2.0 display driver spec
and is capable of running seamless Windows applications. To run seamless
Windows apps on 800x600-16 workplace shell, you need also install
W800SL.DRV.
The file W1024.DLL is a customized PM display driver which supports
the 1024x768-16 color mode PM workplace shell. This file will replace the
default DISPLAY.DLL file in directory C:\OS2\DLL.
The file T640.DLL is a customized PM display driver which supports
the 640x480-256 color mode PM workplace shell. This file will replace the
default DISPLAY.DLL file in directory C:\OS2\DLL.
The file T768.DLL is a customized PM display driver which supports
the 768x1024-256 (portrait mode) color mode PM workplace shell. This file
will replace the default DISPLAY.DLL file in directory C:\OS2\DLL.
The file T800.DLL is a customized PM display driver which supports
the 800x600-256 color mode PM workplace shell. This file will replace the
default DISPLAY.DLL file in directory C:\OS2\DLL.
The file T1024.DLL is a customized PM display driver which supports
the 1024x768-256 color mode PM workplace shell. This file will replace the
default DISPLAY.DLL file in directory C:\OS2\DLL.
The file W800SL.DRV is a customized WINOS2 display driver which
supports Windows applications running on PM workpalce shell seamlessly.
The PM workplace shell should run in 800x600-16 mode (using W800.DLL as
DISPLAY.DLL). This file will replace the default SWINVGA.DRV in
directory C:\OS2\DLL.
BVH driver support, which is a nice feature with our 1.x drivers,
are no longer included in this package since OS/2 2.0 has build-in Trident
SuperVGA support.
PMFIX for 1.x should not be executed under 2.0.
Installation:
-------------
1. Make a backup copy of the following OS/2 drivers:
C:\OS2\DLL\DISPLAY.DLL
C:\OS2\MDOS\WINOS2\VGA.DRV
C:\OS2\MDOS\WINOS2\SWINVGA.DRV
2. Unzip the drivers to be installed
3. Go to a DOS session, run system command SVGA ON
A file called SVGADATA.PMI will be generated in C:\OS2
4. Switch to OS/2 protected mode session and start
DDINSTAL
5. Follow the instructions to finish the rest of the procedures
6. You need to shut down and re-boot the system before the
driver takes into effect

Fail to comply with the above requirements may cause
system hangup during OS/2 boot. In case this happens,
use a DOS diskette to boot from drive A, restore OS/2
default DISPLAY.DLL driver, then boot OS/2 again.
3. Some useful tips for trouble shooting
. Use TVGA 8900C/9000 chips or newer
. Use OS/2 PM 2.0 only
. Do not forget to run SVGA ON system command
. Alt-F1 on system boot time will erase SVGADATA.PMI
Back up the .PMI files before trying Alt-F1
. Make sure your TVGA board has enough memory
. You may choose to manually copy the driver files to C:
Do not forget to backup old drivers
