Anyone here own an HP PC and upgraded the videocard?

[Full Surface]

This is a big dilemma. I got my Radeon 9200 today and when I tried installing it in my HP Pavilion computer (about 2-3 years old, got it in May 2001), my PC wouldn't boot up.

Here's the step-by-step guide I did.

1. Opened the PC, plugged in the PCI videocard, put the VGA monitor cord into the PCI port instead of the motherboard port.
2. Closed it, turned on the PC.
3. The PC had screwed up graphics (wrong colors, 640x480 resolution) but it showed "Detected new hardware, looking for drivers". I insert the ATI catalyst drivers CD I got the videocard with. It prompted me to restart the computer after it finished. I said "NO" and opened up D:\ATIsetup.exe on Start > Run (as it said in the manual). The drivers were again re-installed.
4. I restart the computer and after the Windows ME loading screen, the PC goes into a black background with an underscore in gray blinking on and off.
5. I try restarting again and go into the BIOS. When I go to ADVANCED, it says something about the video display. It has these options:

512KB
1MB
Disable onboard graphics

The bad part is that I can't find a way to disable it. I keep toggling only between 512KB/1MB. No disable onboard graphics.

If you have upgraded a videocard in an HP system before, how do you do it properly?

9100 > 9200...

but... just don't use the original driver disc... i've heard some stories from friends that they tend to fuck things up... go download the catalyst drivers from ati instead...

Thats what you get for buying a pile of crap. Run a search on google(HP upgrades) and you find that your not alone!

Edit

To disable the onboards you need to be in the BIOS settings.
