Jim,

I'm not sure why the BIOS files on the Mac Elite website do not work.
I've taken a few weeks off to work on other problem, but since I now own four of these cards (and I've promised three of them to other people) I'll resume work on this soon.
Once I've found a good solution, I'll be sure to post notice and I'll send you the file attached to a PM).
I already had an ATI FireGL X3 and I decided to flash it for mac.
I flashed it but my screen was always black. I had to edit the rom so that the ID on the rom was 4a48. It is now working but I think the memory timings on the rom are wrong because setting the Memory frequency above 280MHz will give me artifacts (the stock frequency is 450MHz and it worked just fine on windows). The gpu frequency can take the stock 492MHz just fine. The memories on my FireGl X3 are made by infineon and after looking on their datasheet they work between 250-500MHz and have a WR latency of 2.0ns. The Mac X800 XT has memories that can work above 500MHz and they have a latency of 1.6ns.
Have you managed to get your card to work on the stock memory frequency of 450Mhz ?
If so, could you PM me the rom you are using? I have already tried help on other places but I have nothing so far :(
Thank you!
