Fernando, I want to report in with success using your AMD SBxxx v3.3.1540.26 pack to enable AHCI on my HP DV2 notebook with SB600. I slipstreamed it into XP Pro SP3. This notebook actually ships locked into Legacy IDE mode (no BIOS option) but I've discovered that installing AMD AHCI/RAID driver bypasses the BIOS settings. Linux does this too. Also as you can see RAIDXpert util allows configuration and displays information. BTW I am also grateful for your nForce efforts.
