I'm trying to complete a 386 build and am having a heck of time trying to get the system to boot correctly in colour.
Half the time you boot from cold with a Trident ISA 1mb 8900 card, the trident bios logo/msg comes up in colour and then the system is good to go. But if reboot or are on a unlucky chance that from cold boot that the logo comes up in black and white, then everything stays in black and white. Bios, dos editor, windows. Everything in black and white.
I have tried another Trident video card with the same mixed bag results.
Also bought a speedstar 24x video card to try and get rid of this problem. It always shows up in colour when it boots, but after a few reboots you get 8 fast beeps and no matter what you do (change the wait state, irq or go from 16 to 8 bit bios) you cant get out of that 8 beep error code until I switch back to a trident card.
I've disabled video bios being cachable in the bios. Fooled with the video rom being cachable, disabled it all. Still can't figure this one out.
Mobo is a 386 Dx40, 256kb cache, IIT mathco@40mhz. 32mb ram and a 1992 Ami bos w/ opti495 chipset. It's a really good board.
I have another 386 board that I swapped off the ram and video cards to and I get the same colour / black and white results upon booting.
Have also tried just booting with the video card alone and nothing else plugged in - STILL same thing.
Any ideas?
