Disabled VGA Driver

Specs: Wndows XP Pro SP2, Core2Duo 2.00/1024

I was trying to install a new graphics adapter, but the current one wouldn't let me, so I disabled it and restarted. Now there's no graphics adapter. I can see the Windows logo at the loading screen, but then it is just black. Same on safe mode. I tried repairing the installation, but even that appears black. And worse, I can't cancel installation to try to "guess" how to enable it again, as I think the installation is waiting for register key, and every time I reset the comp the installation restarts where it stayed.
Anybody knows where in the registry is the key to re-enable your graphics adapter?

when you were in safe mode did you try removing the display adaptor and monitor in the Device Manager and then restarting the computer

Go into the BIOS & disable the onboard video. Also, change the "initial display" setting from onboard to PCI-e. Safe the settings, exit & shutdown. Install the new card, connect the monitor to it, then reboot & install the drivers.

It's the same in safe mode, the screen appears black after the windows logo at startup.
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.

You said "graphics adapter" in the OP, not "graphics driver"...I thought you were trying to disable the onboard so that you could install a new card.

What happens if you hit the F8 key during bootup & then select "last known good configuration"?

If I chose Last Known Config. it still tries to resume the installation.
I guess I've figured out the driver problem, I changed the BIOS from PCI to IGD... it must work... now it is how to cancel installation. I can't cancel the repair installation, it is stuck at "resuming", and if I try to start over, now it won't let me chose "Repair", it goes directly to a new install. I just *can't* do a clean install and lose all my previous programs. So what files should I delete or change to skip the unfinished installation and return to the previous install?
I bought a PCIX card... it should be arriving today, so that will fix the display problem. Now the thing is the unfinished install.
