heres a question for you BE6 owners

as you know the be6 has the 2 regular ata 33 ports and the 2 udma 66 ports.i have a 40gb maxtor only on this board and im sure its 66 but i cant get it to boot when i put it on the udma 66 port.i would like to run it on one of the 66 ports and the cdr on one and the dvd on one of the 33 ports.i have installed the xp driver for the udma 66 mass storage in XP but i dont think that matters for booting into windows.i just want to run this single harddrive udma 66 can i do it on this board,thanx for any help
