- Video 7 Adapter
- High resolution Video 7 based boards, other than ones using the ht209/d chipset
- are not supported by our video drivers in high resolution. The desktop and OS/2
- full screen may have synch problems. This is because the installation recognizes
- the board as a high resolution board and loads BVHSVGA and VSVGA drivers,
- rather than BVHVGA, VVGA for VGA (640x480x16) support. This however should
- not cause installation problems. After the installation is complete, edit the
- CONFIG.SYS and change the video support statements from:
-
- SET VIO_VGA=DEVICE(BVHVGA, BVHSVGA)
- DEVICE=x:\OS2\MDOS\VSVGA.SYS
-
- (Where x is your OS/2 system drive letter.)
-
- to indicate VGA support as follows:
-
- SET VIO_VGA=DEVICE(BVHVGA)
- DEVICE=x:\OS2\MDOS\VVGA.SYS where x is your OS/2 system drive letter.
-
- If you get SYS3176 when trying to open a DOS or WIN-OS2 session or you
- have intermittent video problems using those sessions, set the following
- DOS settings for that session as follows:
-
- HW_ROM_TO_RAM to ON,
- DOS_RMSIZE to 624.
-
- The settings screen can be reached by clicking with the right mouse button
- over the icon, selecting "Open settings" and going to the "Session" page
- in the notebook.
-
- General considerations
- Our PM desktop device driver supports only 640x480x16 mode (pure VGA).
- OS/2 shipped SVGA support is intended to provide higher resolution modes
- for DOS and VIO subsystem applications only! IBM is interested in helping
- video manufacturers provide high resolution video support. Please
- contact Video 7 in regards to the high resolution video driver
- availability for OS/2. You can obtain more information on SVGA support
- from the README file ( in INFORMATION folder).
-
- If your desktop video is corrupted intermittently, run CHKDSK from an OS/2
- command prompt to determine if any hard disk problems exist. If so, boot
- OS/2 from the installation disk and press ESC when the first instruction
- screen is displayed (you'll see this screen shortly after disk 1 has been
- inserted). This will return you to an OS/2 command prompt. Run CHKDSK C:
- /F to repair any inconsistencies on your drive. Replace C: with your
- boot drive letter if yours is different.
-
- You should also check your BIOS date to determine if you will need an
- update. AMI BIOS should be dated no earlier than 4/9/90 although we
- recommend using AMI BIOS dated 5/9/91 or later. Phoenix BIOS should be
- dated no earlier than 5/11/92 (they recently corrected a bug that was
- causing problems with OS/2).
