Problems getting X800 to work..

[Project Alice]

I purchased an ATI Radeon X800 from eBay, confirmed working. Once it arrived, I taped off pins 3 & 11, and stuck it in my MDD for flashing with graphics accelerator (via screen sharing).
I used the gotoh X800XT reduced rom from the macelite. The flash seemed successful, but upon reboot the card was still not recognized. I tried again, same thing. I then tried the FireGL rom, and that one just fails to flash. I'm thinking my card is an X800 SE or Pro being as it has 1 DVI, 1 VGA, and S-Video instead of 2x DVI ports. But it's 256MB GDDR3 so it should work, right?
Anyone else have more experience with these? I could try flashing it in a PC (assuming the only AGP PC I have will fit an 8X card, haven't actually checked) or just flash it back to the original ROM and stick it in said PC if this isn't compatible. The card was only $35USD which is a good half of what they and FireGL X3's seem to be going for lately so if it has to go in a PC I won't be too upset I guess.

I've attached pictures of the card.

In case you don't know, PC X800 will be VGA only after flashing to Mac, no digital signal output.

No I didn't. I actually thought it would be the other way around. However I can't get it to work at all. I might just end up ordering a Radeon 9600 from a G5 and throw it in there. I can use the X800 in a PC.

There were X800 Pro cards available for the G5 (I used to own one) and they come up on eBay from time to time. That might be a more plug and play solution for you.

The X850 also exists for Mac, but these were rare cards and are hard to find.
