I have a AIW9700Pro AGP card running on a Gigabyte GA8-INXP MB which when I set the bios to auto(8xagp) crashes WinXP to black screen reboot after a while. I've waited for drivers to fix this for about a year but no help. When I run it in 4xAGP, the system is completely stable. The other day I disabled "fast write" in Smartgart and now the system doesn't crash even in 8xagp mode. My question is what is "fast write" and why doesn't it work? FYI, I only have one DDR400 512MB ram chip in the system currently.
