AGP Texture Acceleration in DirectX8.2(final release)

[Hanyawk]

Is there anyway to fix this without a complete fresh OS reinstall.
A long time ago... I installed WIN2K, Asus P5A ALI Chipset 1541, AMD K62-500, 384MB PC100, 20GB and a Diamond Stealth III S540. All went well, finally found a good driver for S3/Diamond Video.
Now I am installing a GeForce4 MX420 and it installs fine with 30.82 Driver, have obtained the latest AGP miniport 1.90, IDE, USB etc and installed them, running SP3, have DirextX 8.2 Final release(was using 8.1).
I can not run an Open GL Screensaver (it generates errors and says to restart application)
in DXDiag, I have found that AGP Texture Acceleration is disabled? GeForce supports this? COme to find out, when I installed WIN2k with S3 Video (same with Voodoo series) AGP Texture is disabled. I understand that for Video Cards with 32MB> will often disable this, as there is not a need to utilize Memory other than what is on Video card to process Textures. My 2nd PC was installed with GeForce Video, AGP Texture is enabled and Screen Savers work games ROCK. But very sluggish with 2nd PC, any ides? Trying to avoid the Reinstall of WIN2K.

The problem is related to the ali chipset and not the size of the video memory.
A friend of mine has a viatech chipset and a GF 2 MX400 64M. His AGP texture acceleration is enabled. But I have the ali 1647 chipset and mine isn't enabled. Two things you can try: Play with your AGP aperture size in the bios, ie. make it bigger.
Check on the ali website. They have a topic under support somewhere dealing with this. It is a value in the registry that you have to add. If this is too risky for you, leave it. But I doubt re-installing the OS will help.
