I built a computer with the Gigabyte GA-8PE667 Ultra mobo and set up two hard drives in a RAID 1 array running XP. The array turned out to be drive F: (drive C: is a zip disk on IDE 1). Everything works fine (except for my wife's stupid realtor software that insists on installing to C, but I was wondering if this is normal for the Promise "Lite" controller, or did I miss a step somewhere?
