- Hi.
-
- I have a strange problem thats occurring with my system. I'm running
- OS/2 2.0 (GA+SP) with Trident 16 bit 800x600x16 video drivers.
-
- Super VGA currently works fine. I have seamless windows and Full
- screen windows at 640x480x256. SVGA DOS programs work great.
-
- Now if I load some device drivers in my CONFIG.SYS (OS/2 drivers)
- the system still works but DOS SVGA no longer works. Also, Windows
- at 640x480x256 full screen acts as if SVGA was disabled.
-
- The device drivers in particular are:
-
- 1. SBOS2.SYS - Sound blaster beta driver
- 2. FMD.SYS - BitFax for OS/2 device driver
- 3. SIO.SYS - Beta comms drivers.
-
- I think I've tracked down what's different with these drivers to the
- normal OS/2 drivers. They display a message on the screen when
- booting up to confirm they installed correctly.
-
- It would appear that any device driver that accesses the screen on
- boot disables my SVGA!
-
- Has anyone encountered this? Got any theories as to how I could
- confirm/deny the above? Better yet, anyone know how I can fix it!!
-
- My system is:
-
- 386DX/40Mhz
- 8MB Ram
- Trident 9000 512K SVGA card
- Soundblaster Pro (IRQ5 DMA1 ADDR220)
- April Fax/Modem internal card (COM1 - COM1 disabled on motherboard).
-
- I'd appreciate any help with this.
-
- Thanks,
-
- Chris Double.
