Nope i dont think its a promise issue,
Before i enable the onboard SATA I tried to put in an extra ULTRA 133 and also tested with a SIS 0680 based IDE controller,
Got the same result with both of thoose controllers..
I think it has something with the motherboard..
Gonna mail both the support of promise and ASUS and see what they say.
I´m not happy to have an SATA 250 gig disked which i cant utilize
