VIA AGP and ATI Radeon driver installation on Windows XP.

I had a hard time upgrading a Windows XP box;
I was upgrading to Windows XP SP2. The box has a VIA chipset and a Radeon AGP 8X model 9500 display adapter.

It upgraded fine, but the display driver wasn't installed.

When I went to install the ATI Radeon driver I got this idiot bother box from the ATI installer that said:

Setup was unable to complete the installation.
Try to setup your display adapter with a standard VGA driver before running setup.

I beat my head against this for a while, and finally figured out that I needed. The Windows XP SP2 disk had an old bad version of the VIA AGP driver (VIAAGP1.SYS).

So, I went to the web site viaarena.com, and downloaded the latest and greatest Hyperion driver kit, and installed the AGP driver, and rebooted.

Upon the reboot, the Windows box knew it had to have a display driver installed. The Find Driver wizard got stuck looking for the driver, so I just ran the ATI install, killed the Find Driver wizard, and rebooted.

Hopefully someone else who reads this can avoid the same hassles.
