So I downloaded Zeus and installed Natit from there. Same result: chime, whirring hard drives, and blank screen forever.
What to do, what to do...
Same as my xfx4890 ZDFC. But works fine in XP.

You are lucky.
Download GPU-Z and dump a copy of your ROM. There have been MANY people who were sorry when they didn't do this and we hadn't already written the EXACT ROM their card needed.
You can then use HexEdit to look at the ROM and compare to whichever one you were going to flash with. Opening for first 60,000 bytes or so should be identical, you'll be able to see right away if not as Version Number appears in top of page.
I think there is even a Windows flashing utility for ATI cards but I have never used it myself. DOS is my preferred flashing zone, easy to use once you know how.
I was able to boot into windows (I guess with default drivers--I didn't install anything). I Dl'd GPU-Z, but when I started it up, it gave an "unknown architecture" dialog box, and the app didn't populate with any information.
Any suggestions?
Have you tried to go through the flash process using Zeus from within OSX yet like you tried last night?
I don't think that GPU-Z is going to work without bios support (none on Mac Pro)
I can't. Using either Natit contained in ATI Flash tool, or the more specific kext files I found in another thread dealing with my exact card, I am still unable to get past a blank screen on boot with the 4890 installed.
I think I misunderstood Rominator: I thought I could boot into XP via boot camp and use GPU-Z to dump my ROM. Do I actually need a non-mac PC for this?
I think, however, that I have located my exact original ROM in a file Cindori posted to the main thread. (Of course, for safety, it would always be better to make a backup direct from the card.)
So am I looking at the BootCD method? Perhaps DOS? I was pretty proficient at the DOS command prompt about 100 years ago, so I would not balk at the idea. But can I do it all from the mac? That's all I've got to work with.
Thanks.
a mac pro booting windows is a PC. ofc you can dump rom. need ati drivers installed though ofc.
look in my signature for how to wire molex properly
