What BIOs settings should my Video card have?

[Debo420]

What should i enable and disable under the AGP portion of my BIOS? I have fast writes enabled and AGP aperture size set to 128MB... My Video card is a Radeon 9100 128MB, any responses will be appreciated.

Most say to disable fastwrites because it can sometimes hinder your overclock and cause instability. Seems to work fine on my system, but tests in 3Dmark2003 indicated absolutely no performance gain when enabled.
