Remember, if it is allready loaded on one HDD in RAID/AHCI mode, you should be able to easily migrate to RAID "0" via the Matrix Mannager in Vista. It works this way for XP x64
I’m not sure what you mean when you say “RAID/AHCI mode”. In the BIOS I can only choice RAID or AHCI, not both.

What I can’t figure out is that when I load Windows XP/32 Bit, I have no problems at all with the RAID drivers so it can’t be a BIOS setting.
