X800 XT for Powermac G5 rom flash

Hi all,

I have a PM G5 Dual 2Ghz. It has a stock 9600 and I want to change it with a Asus x800 xt Premium Edition.

What I did was:

1: Read the mac elite wiki
2: downloaded Atiflash 3.60
3: downloaded reduced size rom of 64Kb for the X800 from the mac elite wiki
4: Found out what the original device ID was for the videocard (4a50)
5: Changed lines 3 and 8 in the rom to match the device id.
6: Backuped the original rom using atiflash -s 0 backup.rom.
6: Flashed the new rom using atiflash -p 0 newrom.rom
7: Flash is succesfull....

but... the device ID has not changed. And that is where my problem is I do not know how to continue. Asked the same question on the strangedog forum, but it seems very slow.

Any ideas?

still stuck. Anyone please?

OP, did you try to flash with ROM's default DID (4A48) and/or flash the card in Mac? Card was tested in Win before flash?

1: I did flash with the 4a48, the card has no display in the mac, but it boots
2: Flashed the card in a normal PC
3: Card works fine in windows

As for flashing the card in the mac, I have no PCI card that fits the PCI-X slots.

Then try to flash it via VNC with screen sharing.
And stupid question : have you tested both outputs of the card? X800 after flash is VGA only.

I ill try VNC, what is the difference between flasing in a PC and PM? I know only vga works

thanks for you help!
