Has anyone tried a stock "PC" nVidia GeeForce 2 mx in an AGP G4 or does it have a special chip to make it Mac-compatible? Just curious!

you can't as of yet put a PC version of the GeForce into a macintosh. I don't remember the exact terminology but they aren't compatible with something yada yada. Eventually hopefully...

Would be nice if they made flash update like 3DFX did for Vodoo 3 if it´s possible that is.

Festoons, you're thinking of the endian crap.
Its just not compatible.

Rumor has it that it actually IS possible to flash a PC MX card for use in a Mac, but no Mac ROM image (or flash utility, for that matter) has been released yet. One of the features of the MX chips is that both endian schemes are supported in silicon. Which one gets used is a function of the ROM instructions. What happens if you stick a PC MX video card into a Mac is just that the Mac will not recognize the card at all. Video cards must have Mac drivers, probably at the ROM level since the video card has to be recognized before any drivers are loaded from the startup volume. Where the MX card would have a big advantage over the 3dfx Voodoo 3 cards (which were flashable) is that true native Mac endian support is in the GPU already and there would be no translation overhead like the V3 suffered from with Macs. For native Mac endian support all that is required is for the ROM to set the switch within the GPU.

What about the fact that the bus speeds are different?

I know for a fact a GeForce2 Ultra will not work. There's problems nVidia needs to work out. We tried it on my Gigabit Ethernet G4.

Right, the standard GF-2 and GF-2 Ultra chips are not compatible with the Mac. The MX archetecture is a more recent design (even though it is a slower one) and was the first to have the Mac endian thing enabled. So far only the GF2-MX and the portable version of it (GF-2-Go) can be used at all in Macs. All future nVidia chips will have Mac support in silicon, acording to the nVidia press releases.

Could one drop it into a pc agp machine, and use a flash extractor on it? Even if we have to stick it in a pc to do the upgrade, then at least we have the option
