3dfx's recommended BIOS settings

My recommended BIOS settings are to ensure that your card goes as fast as possible. These may be somewhat different than what 3dfx recommends: to ensure compatibility. Therefore, I recommend you at least try 3dfx's recommended settings, especially if you have any problems with your video card. Here is what 3dfx recommends:

Assign IRQ to VGA (or video) - Must be enabled or set to "auto".

Video BIOS cacheable - Should be disabled.

Video BIOS shadow - Should be disabled.

VGA Palette Snoop - Should be disabled.

PCI Palette Snoop - Should be disabled.

AGP Turbo Mode - Should be disabled.

Write Cache Pipeline - Should be disabled.

Read Around Write Back - Should be disabled.

AGP Aperture size - Set to 256 MB or default.

Level 2 Cache - Should be disabled (Socket 7 boards). [I personally recommend that you leave this enabled unless you have severe problems]

Resources Controlled by - Set to Auto.

PNP OS - Set to Yes.

I strongly recommend that you try my settings AND 3dfx's settings to make sure that you're taking full advantage of your video card. If one is better than the other for your system, please let me know so I can make a note.
