Hi all. I’ve got a bit of a problem that I don’t recall ever experiencing before. My DFI G7S620 refuses to display from my ATI Graphics Ultra Pro (Mach32 chipset) during boot-up. The board defaults to the integrated graphics instead. This is a known-good PCI card that works in other motherboards (a Socket 478 board and another LGA 775 board, specifically). I haven’t found a BIOS setting on the G7S620 that seems to affect the PCI bus timings or voltages that might cause this problem. I’m really at a loss.
This motherboard boots fine with other vintage PCI graphics cards such as my Matrox Impression Plus and Cirrus Logic GD5446. I haven’t tested all of my PCI cards for compatibility, but the ATI card is one I’d really like to use with this board (it’s an awesome card for early versions of OS/2).
Has anyone here ever had a random PCI card fail to work with a mid-2000s motherboard at boot time? If so, how did you resolve the issue?
