And I don't have a PCIX card. What I was actually trying to install were the correct drivers for the onboard chip, as it was using the default VGASave adapter. It didn't let me change the driver, so I disabled it to install the drivers from the manufacturer. Now there's no way in, I can't see the desktop.
Perhaps enabling VGA mode would work, but now I'm stuck with an unfinished install. Every time I restart with the CD in, the installation tries to resume, and the screen goes black, and if I restart without CD, the installation tries to resume but stucks at the beginning.
