- Hi.
-
- I've got a problem with my OS/2 system and was wondering if anyone
- else has experienced this problem.
-
- When OS/2 boots, the OS/2 logo appears. This clears with a cursor in
- the upper left for about 30 seconds then the WPS desktop appears.
- This is a normal boot.
-
- If any device driver (loaded in CONFIG.SYS) displays a message on the screen at the stage of the cursor being in the upper left I lose Super VGA
- ability in my DOS/WINOS2 sessions. It doesn't even have to be a
- device driver displaying the message. If the HPFS system does an
- autocheck of the disks and displays the results this causes the
- problem too. Any access of the screen at this point appears to be
- the problem.
-
- Luckily, no original OS/2 device drivers write to the screen. Some
- third party drivers I want to use do and this results in no SVGA.
-
- I still get SVGA on the WPS desktop with no problem (ie. at
- 800x600x16 resolution). It's only DOS & WINOS2 where I lose it. Any
- SVGA program (CSHOW, WINOS2 at 640x480x256) displays strangely. I
- also get sync problems swapping between DOS and OS/2 desktop.
-
- If I remove any drivers that display to the screen, all is ok again.
- Weird. Anyone else experiencing these problems? I would appreciate
- any ideas as to how to fix this!!!
-
- For the record, my system is:
-
- 386DX/40Mhz 8MB Ram
- 200MB hard drive
- Trident TVGA D3.01 9000 card with 512K
- Soundblaster Pro at IRQ5, DMA1, ADDR220
- Internal 14.4K Modem/Fax at COM1
- COM1 disabled on motherboard leaving only COM2.
- LPT1 at IRQ7
-
- I've tried disabling caching on the AMI Bios setup, enabling caching
- but no change.
-
- If you have any ideas I'd love to hear from you!
-
- Thanks,
-
- Chris Double.
