The mac rom is from the FX5200 cards which were supplied or came as an
extra with some macs - I think the early iMac G5 had 5200 graphics as well
as an FX5200 Ultra with some tower systems. Roms vary from model to model
and manufacturer to manufacturer - bootstraps, device id etc as well as
memory addressing as some are 64 bit and others 128 bit. The mac elite wiki
downloads section has a mac FX5200 rom as well as five modified roms to
flash pc versions of the 5200 card. It's not an easy card to tackle given
the variables and 100% working performance may be difficult to achieve.
Certain parts of the mac rom like device id may need replacing with code
from the original pc rom.
I have a cheap agp FX5200 with 256MB of memory which I flashed for fun a
couple of years ago - works in a mac but only on safe boot or it rustles up
a KP - and there's no signal from the dvi port so it's twin vga only -
always meant to edit the rom but it's fairly slow with TSOP ram and
practically obsolete so it ended up in the spares stash - for agp a Radeon
9800 Pro or XT with 256MB is so much easier to flash and so superior in
terms of performance - and cheap too....
