my win2k doesn’t recognize my HD array 1

when i was attempting to install win2k with two 6G hard disks that form a HD arry 1, win2k said it can’t find any hard disk on my computer, i think it didn’t load the HD array driver at the beginning og the installion. What shall i do to make win2k recognize my HD array?
my HD array is formed by promise fast track ATA-100 controller which is integrated on my mother board.(giga AMD 761+via 686B chipsets)
