I have the following problem with my ASUS A7A266 rev 1.10 motherboard and NVIDIA GeForce FX5600: I can't get AGP FAST WRITE to work in Windows 98SE. I've enabled AGP FAST WRITE in the BIOS. I've tried the ALi AGP Driver versions 1.91 and 2.01 with NVIDIA driver 55.64, but Aida and Riva Tuner keep showing it as disabled, and I can't enable it in Riva Tuner either.

Can anyone tell me what else I can do to get AGP FAST WRITE working in Windows 98SE?

I have the following PC.
A7A266 rev 1.10
AMD Athlon 900
Geforce FX 5600 128mb
512mb ddr
Sound blaster live 5.1 SB0060
