Flashed FX5200 Ultra Issues in Power Mac G4

The nitty gritty:
QS 800Mhz DP
1.5 GB RAM
10.5.8

PNY GeForce FX5200 Ultra 256MB (flashed with the modded ROM for 256MB FX5200 cards from TheMacElite)

It'll boot with the happy chime, but when the screen finally kicks in it's just a mass of multicolor pixels with the word "Apple" appearing in random locations. Network shares are accessible and I can ssh, but I can't screen share with it.

Did I botch the flashing process, are pins 3 and 11 not fully taped off, should I take the PCI Radeon 7000 out, or is something else wrong here?

Everything works peachy with the GeForce2MX TwinView in place, but I was hoping to get a bit more out of this old workhorse when I stumbled upon that NVIDIA card in the depths of my desk drawers.

Any help or pointing to other resources would be appreciated!

5200s don't do 1920x1200 via DVI...they try, and some may work, but most fail...so if you are doing dvi....a no go.

Using it with VGA, but that's good to know if I ever decide to upgrade the monitors hooked up to it.

you need to match ROM to the card.

There never was a 256 Meg Ultra, they all had BGA RAM of 128 Megs. The Non-Ultra cards used TSOP RAM in 256 Meg versions.

I think that's the problem then, for some reason I was assuming it was a 256MB card. I'll reflash it next week and try again. Thanks!!

Got the right firmware on there and it works perfectly. Thanks!
