So I know boot camp doesn't support windows xp 64, however I have the C2D 20" iMac and I'd like to match the 64 bit OS with the 64 processor.

When installing, it works fine. When trying to install boot camp drivers, it doesn't let you, hence the no support for 64 bit.

I've gotten around the driver disc so far, manually finding all the drivers.

The last one I'm having a problem with is the video card, I've tried finding a standard VGA driver, the catalyst drivers, and the omega drivers.

The drivers I've found either don't work for 64 bit, or cannot find compatible drivers to update from.

I have a Radeon HD 2600.

Thoughts?

I've got the x64 bit Bootcamp here. Will upload.

Is that a joke? If not, what's your website..?

Yu can find the driver son torrents.
