It was fairly common among the old flashing brigade - much less common
now due to the death of the original pci and agp - and is usually achieved
by running Panther through chicken of the vnc - or any vnc controller.
Panther because it will boot with a non mac card installed. The flashing
software is Graphiccelerator but be aware that it will flash all the ATI
cards installed - both pci and agp - a cautionary note if you do have an ATI
pci card to boot and flash the ATI agp.
There never was a 128MB ATI 8500 for the mac so no standard rom - just
the 64MB version - so you may end up with half the vram. Also the 128MB
version for the pc was known as the 8500LE and as far as I can remember a
cut down version with vga and a strange dvi port that has no vga and will
not take an adapter.
Aquamac details the how on his site with an X800...

Hello David!

I suppose what you're proposing could work. I don't know if the
software exists for Macintosh to flash graphics cards, though. I
recently flashed a Geforce FX5500 to a FX5200, but had to use a PC to
get it done, as the software required an x86-compatible system.


Greetings,

Eelco.

re-flashing video cards for use in Mac computers

[David W. Morris]

Does anyone have any experience in flashing a PC video card with the  
AGP slot connection for use in a G4 PowerMac (or G5 PowerMac), by  
installing it into the Mac and using a remote desktop program to  
display the screen on a different computer, so the re-flashing process  
can be run on the Mac while it has no working video card display?


Sounds like a crazy idea, I know.  But if a person doesn't have a  
Windows PC with an AGP slot any longer, and doesn't have a PCI video  
card that works on a Mac, what are the other options available?


I have a 128mb VRAM Windows version of the ATI Radeon 8500, that I  
want to use in my dual 1.25GHz G4 PowerMac MDD, which I have upgraded  
to stock Apple dual 1.42GHz  G4 CPU module.

dual booting MorphOS2.7 & MacOSX10.5.8 on my 1.5GHz G4 MacMini and my  
dual 1.42GHz G4 PowerMac MDD, and MorphOS3.0 beta & MacOSX10.5.8 of  
15" & 17" 1.67GHz  G4 PowerBooks.
