Another oddity with this GeForce 5200 FX. It was advertised as 128
MB, and shows up in System Profiler with 256 MB VRAM. There are two
labels on the card itself. One says:
FX 5200 128MB/128bit DDR
The other:
ZO52-CAGP
5200 128 MB AGP
The nefarious underworld of video cards. Who knew they were so
weird? I didn't.
There are likely some issues here. This card is made by Zogis, so it's
a flashed PC card for certain. As far as I can tell, all the 128MB
cards were 64bit cards. It appears the 128bit cards were all 256MB.
It doesn't appear you'll need to tape pins 3 & 11 for this card to
work in your Sawtooth. If you ever plan to transfer this card to any
of the ADC Macs which are the Cube, DA, Gigabit, QS, and MDD you'll
need to fix pins 3 & 11. See:<http://themacelite.wikidot.com/pins-3-and-11

There's a good chance your ROM may be wrong for this card. The ROM
revision doesn't really help because there was only one Mac ROM,
version 2060, and every card will have v.2060, but there are several
versions of 2060 ROMs, and they vary for different speed VRAM & GPU,
and also for 64bit or 128bit.
If the card has a 256MB 128bit ROM and it's really a 128MB 64bit card,
this could cause the panics you're seeing because the Mac would be
trying to address VRAM that doesn't physically exist.
My advice is to first figure out exactly what card you have. Next,
you'll want to be sure the ROM you select has the correct bit, MB, and
speed to match your card. I think the real Mac card uses Device ID
0x0322 rather than 0x0321 so you may want to have that changed also,
but I'm not sure if it matters or not?
It may take some experimentation to get the correct ROM so that this
card doesn't panic. I sent a link to the ROMs repository. I think it's
likely you have the wrong ROM for the physical hardware on the card,
and that getting a matching ROM will stop the panics. I might able to
assist off-list if you need further assistance.
Here's some reading on the FX5200:
