GA-BX2000+ WIN2K problem

I have a giga-byte GA-BX2000+ board which i have updated the bios to latest from website.
The probloem is the built in promises ata controller, win2k pro doesn't liek it,keeps reporting paging errors and fatal controller errors,also says controller drivers are out of date (over a year old) does anyone know where I can get latest drivers from or what the problem is?? Promise say they don't support that conroller, and to get drivers from gig-byte. Giga-byte don't have any controller drivers that I can find and say I should get them from promise

Did you go to the windows update page and scroll down to the bottom after it examines your computer. At the bottom is a list of device driver updates for you machine.
