Instructions on how to manually install display drivers. Downloaded
from the OS/2 Shareware BBS, tel. 703-385-0931.
---------------
I beat the guys up and got the MANUAL way to change display type WITHOUT
needing to install, here tis....
----------------------------
In all cases below, you must have diskettes 6-15 (diskettes installed
under PM - may be different depending on driver level). When the
instructions say: 'UNPACK A:filename targetdrive:', this implies that
this command is run against each of the diskettes as the file may reside
on any or all of the diskettes.
For CGA:
1. UNPACK A:CGA targetdrive:
2. copy (or rename) the file \OS2\DLL\CGA.DLL to \OS2\DLL\DISPLAY.DLL
3. change the CONFIG.SYS
SET VIDEO_DEVICES=VIO_CGA
SET VIO_CGA=DEVICE(BVHCGA)
remove any reference to DEVINFO=KDB,xxx,xxxxx
For EGA:
1. UNPACK A:EGA targetdrive:
2. copy (or rename) the file \OS2\DLL\EGA.DLL to \OS2\DLL\DISPLAY.DLL
3. change the CONFIG.SYS
SET VIDEO_DEVICES=VIO_EGA
SET VIO_EGA=DEVICE(BVHEGA)
DEVINFO=KDB,EGA,xxxxx
For VGA:
1. UNPACK A:VGA targetdrive:
2. copy (or rename) the file \OS2\DLL\VGA.DLL to \OS2\DLL\DISPLAY.DLL
3. change the CONFIG.SYS
SET VIDEO_DEVICES=VIO_VGA
SET VIO_VGA=DEVICE(BVHVGA)
DEVINFO=KDB,VGA,xxxxx
For 8514:
1. UNPACK A:8514 targetdrive:
2. copy (or rename) the file \OS2\DLL\8514.DLL to \OS2\DLL\DISPLAY.DLL
3. change the CONFIG.SYS
SET VIDEO_DEVICES=VIO_8514
SET VIO_8514=DEVICE(BVHVGA,BVH8514)
DEVINFO=KDB,BGA,xxxxx
For XGA:
1. UNPACK A:XGA targetdrive:
2. copy (or rename) the file \OS2\DLL\XGA.DLL to \OS2\DLL\DISPLAY.DLL
3. change the CONFIG.SYS
SET VIDEO_DEVICES=VIO_XGA
SET VIO_XGA=DEVICE(BVHVGA,BVHXGA)
DEVICE=targetdrive:\OS2\XGARING0.SYS
DEVINFO=KDB,VGA,xxxxx
Where xxxxx = targetdrive:\OS2\VIOTBL.DCP
This does not cover dual display systems, those get somewhat more involved.
This also does not cover changing the OS2.INI file, but since these are
changes to colors and must be done programmatically, it is not usually
worth the effort.
