Ok, now it makes more sense. I bought the card because it had ADC on
it. I wrongly assumed that I could just tape the pins and go. Im
using a 23" Apple Cinema display on my G4 QS 933 and needed the ADC
for now. SO - a G5 ADC card will not fit in a G4 because the card
and AGP slot was redesigned, but a G5 NON ADC card will fit in a G4?
That explains why the flashed pc cards work.
The slot issues only concern adc cards and even then the agp
pro slot in
the G5 will perhaps take any agp card without adc. It's just that
the adc
cards designed for the agp pro slot were not usable in earlier macs
due to
the shifting of the adc power pins out of the main slot and onto a
stub. The
presence of the adc power pins in the main slot effectively meant
that no
adc equipped G4 will boot with an 8x card installed - thus the tape.
The 7800GS is troublesome due to the bios change - the mac
version and
the early pc version had the G70 bios - the pc version quickly
changed to
the later G71 bios. G71 cards will not flash to mac - only the
earlier cards
with the G70 bios are compatible with mac flashing. And the mac
card only
had 256MB AFAIK so the 512MB may present problems too - possibly
all the
512MB cards are later cards and G71. G70's are occasionally
available -
usually involves mailing the seller to get the bios from the back
of the
card - begins 5.70 (G70) rather than the later 5.71(G71). The BFG
card was
favourite as I remember though several other brands made a G70
card. The
Radeon X800 is also a very good card - problems again though. Have
a look at
aquamacs site and forums for info.....
