So I just build a new pc around Asus p5k Premium and has been reading through this thread. Disturbing info. I still have 7 days to return my motherboard if it's really important.

Have been testing the ICH9 controller. I only have one SATA 2 drive:WD7500AAKS. I installed it as AHCI succesfully in winxp 32bit and Vista 64bit. No eventviewer warnings. Runs perfect.

So I wanted to test the raid config. Borrowed 2 wd800jd Sata 2 drives and enabled RAID in bios. Booted and configured stripe Raid0 and tried installing winxp 32bit.

However the problem is that my sytem refuses to boot of any winxp installation CD (I have several). The CD spins up but it doesn't start booting. The cursor in upper left corner just sits there blinking and nothing happens ?
What could be causing this. I would really like test if raid works on my p5k.

If I change setting in bios to ACHI it boots just fine on winxp installation CD..

Anything I missed ?

Any helpful comments will be much appreciated....

Thanx in advance
