Yes it's easy, first check for continuity since it can be the case only the lacquer is scratched. They find the 2 points that trace connects together and use some kynar wire to re-connect them.

For a moment I thought that somebody brought up my post with similar name 😢. If those traces are actually cut, test it in that condition and report results, it won't damage the card, worst case scenario would be hanging games on start up or weird texturing problems.

The current state: system boots, but nothing can detect the card. Latest Glide drivers all say the same thing.

At first I thought that those traces lead to memory, but they actually connect FBI with TMU0, must be a part of address/data bus for main ICs. Card with such damage should still be detected by PC, check if there are no bent and shorting pins on FBI. Also, use reference drivers when you are not sure if card is working as they are stable and easy to install/uninstall.

The card is currently being used in a pure DOS context. What's the best way to test?

It should still be detected as PnP Multimedia device in BIOS.

DOS is not ideal environment for testing, you need to be absolutely sure that card is being detected by OS and is properly installed, only then you will know whether glide/d3d applications doesn't work because of software or hardware issues, on a GUI based OS is much simpler to see that. I'd suggest you to put card in PC with Win9x or WinNT based OS and run "Donut" tech demo, it allows to tinker with many hardware features of the card, + you will also be able to easily change environment variables in registry or batch file on the run, if needed.

I'm not sure what to look for. BIOS allows me to configure which resources are allowed for PnP allocation, but I don't see a list anywhere.

Thanks for the suggestion. I'll throw this card into a machine I can do that with.
