AGP Sideband addressing and fast writes

hey all!

I'd like to enable sideband addresssing and fastwrites(geforce3ti200)...my bios says that I have fast write enabled and there's no spot for enabling sideband addressing (mobo=kt3 ultra-aru). Powerstrip says that fast write is still disabled and i can't figure out how to enable sideband...here's the report:

Is there a way to enable sideband addressing on the kt3???

Thanks!
