This motherboard was found without a BIOS chip and with swollen caps.
After recapping it, I couldn't determine what's the board version, where can that be found?
I noticed that there are 6 pairs of pins in JP30, which should make this board the v2.0, I think.
Nevertheless, only 128K bioses worked. The 256K bioses (with a 256K EEPROM, of course) boot, but they produce lots of colorful artifacts on each side of the screen and you can't get past the POST screen.
5bt-1b7.bin from theretroweb seems to be the best performing BIOS memory-wise. However this one and all the other 128K ones I tried have a serious, strange problem with the DVI output.
Using a Radeon 9250 PCI:
When I use the VGA/DSUB output everything works perfectly.
When I use the DVI output, certain software (PCPlayer), especially software that uses DOS4GW (DOOM, DOOM2, WARCRAFT 2) doesn't even try to load. There's no output after running the executable. The system completely freezes.
I tried modifying some BIOS settings to no avail. I used a Pentium 133 and a Pentium MMX CPU.
Is this a known issue? What could be the cause?
The same video card worked fine on an M919 with a DX66 so the card should not be the problem.
