bought this Soyo DSP32805B Ver 1.0 VLB video card with missing bios chip, any chance where I can find the bios dump for it? pcb near bios says 27256 so apparently it's 256kbit or less in size

So I flashed it on W27C257-12 and it didn't work or a card might be dead, also apparently I got vendor incorrectly, it's ExperColor DSP
32805B Ver 1.0, also it's layout and everything looks exactly as Soyo DSP32805B

do you have any bios dump for this variant or it's same bios?

I doubt it is the ROM provided as the card appears fully functional here

Did you try other S3 805# BIOSes?
