thats one possibility.. but im starting to think its because of the motherboard that hes using to flash with...
like ive said a few times now.. i had problems with one board. the flash would work but the card didnt work.. then i flashed in another pc motherboard.. and it just worked.. and i thought the same as him.. that the card couldnt be flashed and i almost threw it out... but it wasnt the card or the rom but the motherboard that i tried to flash it with..
it may have been because this board i originally tried with was only an AGP 1x or 2x motherboard... maybe u need a pc motherboard that is 4x/8x agp maybe for it to flash correctly
the first board i tried to flash with: Abit BE6 (agp 2x i thnk) <- flash was successful, but card did not work
production date of mb: 1999
the 2nd board i flashed it with: Asus P5PE-VM (agp 8x) <-- flash was successfull first try worked in the powermac g5
production date of mb: 2006
take note of the notch location in the agp slot on the boards
according to the notch is the power supplied to the graphics card..
either 3.3v or 1.5v
perhaps this is the "key"??
mactron - which voltage is the slot on the pc board u are trying to flash it with?
apparently i had success with the 1.5v slot and not the 3.3v
