Video Card Troubles ?!?

[Dnal]

I have a 450Mz PMG4 Sawtooth that seems to be very picky on the video cards it likes.  I have an ATI R128 PCI card and ATI R128Pro that I can get it to boot with.  I purchased a PC 9700Pro to flash.  That didn't go well (using Graphicellerator).  At one point I thought I got it to take the flash, but every time I boot with that card, I get nothing.  It will boot with my PCI card, but doesn't show anything for the AGP card in ASP.

Then I found 3 Mac AGP cards for $25 on Craigslist and ended up with a card labeled MAC RADEON 9000, another card that appears identical, but is not identified and a long GeForce 4 marked card.

Installed the GeForce first (Ge4 Ti 4600!) and it booted right up.  I found some 3.5.2 drivers for OS9 (which also work under 8.6).  So, no problems here.  (But are there OS X 10.4 drivers for it?)

Then I installed the MAC 9000 card.  NOTHING.  Wouldn't show any signs of lighting up the monitor.  Pushed the CUDS, no dice.  So, figured it might be bad and went to the next one.

The non-marked ATI card had the same result.

So, I put my ATI PCI card in next to one of the AGPs, like I had when I was messing with the 9700 and IT won't light the monitor either. 

I tried zapping the PRAM, but it will not give me the second chime.  So it seems to freeze.  

Am I doing something wrong?  Is the R9000 a 4x only card (I don't thing they are)?  

Any suggestions on the R9000 or R9700 would be greatly appreciated

I've used the R9000 in all AGP G4 Macs. Maybe you have the PC versions. The  Mac R9000 should have an ADC connector

Have you taped the pins on the PC flashed Radeon 9700 to get it to work @ AGP 4X?

I've just flashed over a PC Radeon 9800 Pro for my MDD - taped pins but notice there is also a resistor removal mod to permanently force it to AGP 4X, which I'm considering.

The Radeon 9000 would have come from an MDD, it should work fine in a lesser G4 tower.  I'd clean the AGP slot out using electrical contact cleaner spray.

On the 9700 card, I did not tape the pins, since I have a Sawtooth (non-ADC) it does not use pins 3 and 11 for whatever purpose the ADC Macs use them for, so I was told it was not necessary.  I also believe mine is AGP 2x, but could be wrong.

On the 9000 cards, they are definitely Mac cards.  One is labeled as such and both have the extra spade connector and ADC outputs.

I will try to clean the slot, but can't figure out why the GeForce and R128Pro work.  Unless these cards don't like to step down to 2x.  (there is a post in the forums of one guy saying he did this.)
