For test purposes, use it as intended: Master of Secondary IDE channel, alone on a high quality 80 wire ribbon cable.
Have your computer's BIOS (standard section, usually) set to auto detect and auto type the master of secondary IDE channel.
UDMA 2 is good news.
P.S. Either switch it to BenQ retail firmware, or use G7P9 (very easy, works very well).
That will give you a good starting point.
