I got this board a few months ago and it's honestly driving me crazy.
I wanted to build a nice Windows 95 machine with this and put an overkill graphics card into it.
There are three PCI cards at my disposal and only the worst one of them all even POSTs.
- ATI Rage 128 - black screen, board hangs
- ATI Radeon 9250SE - black screen, board hangs
- Matrox Mystique 220 - boots fine
Since this is a really early Socket 7 board with AT power connectors and 5V PCI only, I immediately thought about the great adapter project from here and converted one of the PCI slots to 3.3V. Still, no dice, even though I did the mod properly and have 3.3V everywhere it should be.
Since I don't really like giving up on old and obsolete hardware I then got a postcode analyzer card.
The board at least tries to boot, which is nice - but with both ATI cards, it stops at 0dbf:
Almost at my wits' end I tried one last thing: Update the BIOS. I noticed that my board had such an early BIOS version, it wasn't even on the web anywhere.
So I submitted that to theretroweb (at least something I was able to contribute) and updated my board to the latest BIOS 0312.1.
Apart from the board now properly detecting my K5 90MHz correctly, it still didn't change anything. I'm out of ideas.
Do I really have to give up here? Is the SIS chipset really such a piece of absolute garbage that it can't even drive a Rage 128? 😒
(I also hate that it can't even boot from an IDE CDROM drive, but let's not get started on that...)
