I just got this XPC a couple of days ago, and am having a heck of a time with this controller. As I'm trying to setup a WD Raptor drive with the AHCI on Vista to no avail. I was able to install XP using this drive in IDE mode, I feel that the machine works well. Another problem, is that it won't recognize my USB floppy drive. This is what's preventing me from using AHCI with XP.

I have updated to the latest firmware, to no avail. What am I missing?

Thanks In Advance
