- GENERAL VIDEO PROBLEMS
- ----------------------
-
- 1) Video goes out of synch when switching from DOS full screen
- or WINOS/2 full screen to desktop.
- This is usually caused by Tseng ET4000 chips in the video
- controller (batch TC6059AF or higher only!). If the customer
- has these chips in his video board, send the fix for APAR
- PJ03677.
- 2) SYS3176 error when starting a DOS session.
- Try setting HW_ROM_TO_RAM to ON for each session that is
- having the problem. Also try changing DOS_RMSIZE to 624
- instead of 640. If this does not work, the VSVGA.SYS fix
- from IBM might resolve the problem.
- 3) ATI 8514 Ultra or Graphics Ultra locks with white screen on
- bootup.
- The older ATI ROM chips return an incorrect monitor ID when
- queried by OS/2. Have customer call ATI at 416-756-0711 to
- obtain an update. Remember, these boards MUST be set up as
- an 8514 PRIMARY display and the statement
- DEVICE= OS2 MDOS VVGA.SYS
- MUST be changed to
- DEVICE= OS2 MDOS VSVGA.SYS
- 4) C0000005 error on bootup.
- If the customer has Western Digital chips (C30 or C31), with
- 1MB memory, send the fix for APAR PJ03721.
- If not, remove the SVGA info from the CONFIG.SYS file. Note
- that this will limit the user to VGA only. Change
- SET VIO_VGA=DEVICE(BVHVGA, BVHSVGA)
- DEVICE=C: OS2 MDOS VSVGA.SYS
- to
- SET VIO_VGA=DEVICE(BVHVGA)
- DEVICE=C: OS2 MDOS VVGA.SYS
- 5) Trident video problems: If the user is experiencing
- problems with super VGA on Trident based video boards,
- they will need to call Trident (not IBM) for the proper
- SVGA driver. If they have problems with the driver that
- Trident sends them, they need to call Trident, not IBM.
- IBM only supports VGA mode on Trident boards with 8900 or
- 9000 chipsets. The 8800 chipset is not currently supported
- nor do I believe that it will be.
- 6) Dell computer Video problems. Dell's 486/50 uses a
- Western Digital 90C30 chip. Our standard BVCHSVGA.DLL
- fix should help. Other models (325SX, 325, NL25, etc.)
- do NOT use this chip and this fix DOES NOT apply.
- Dell uses a customized Phoenix BIOS. Here are a few
- CMOS settings that have been known to help. Use
- CTRL-ALT-ENTER to access CMOS setup:
- FAST_VIDEO OFF if sync problems
- FAST_VIDEO_BIOS (shadowing) OFF if problems
- BIOS_CACHING OFFif problems
- COMPATIBILITY_SPEED ON for faster Mhz machines
- 7) Errors loading video drivers on bootup. The selective
- install utility sometimes will add the same device driver
- statement more than once to the CONFIG.SYS file. This will
- result in an error message every time the user boots up.
- The system will function properly and upon investigation
- you will find that driver file DOES exist in the proper
- directory. It is simply trying to load the driver twice
- during bootup, the second attempt will fail. Remove the
- duplicate DEVICE= statement from the CONFIG.SYS.
