The BIOS was unsoldered and read without any problems, the chip was erased and the same dump was written again.
On the postcard, it sometimes stumbles on the d0 code, sometimes it gets to the a2 code. There's 3.36V on the RST# pin of the AGP.

Award or AMI ? Anyway, post d0 and a2 are weird errors.
I hope you tried to run the Radeon in different PCs or the PC is working with similar AGP cards for sure.
I don't have much experience about graphic cards but I would think the GPU chip is cooked (I really don't like the color of thermal grease) or has loose contacts underneath

It's AMI BIOS... Sure, I tried another platform to check and yeah, I also don't like the color of the compound - it's too brown:

Most likely it had the same cooler as this board:

Along with this it has a frequency from the Pro version — 378 MHz. Perhaps the chip itself is finished... So, I guess this board is going to the back shelf until I understand things a little better...
