Same problem. Unable to create a AHCI enabled XP 64 Setup CD. I created various enhanced Windows XP CDs before, but as soon as it comes to Windows XP 64bit and AHCI I completely fail. Mainboard: ASUS P5Q-E (ICH10R) There's a F6 driver disk on Intel's site for download (64bit) - slipstreaming it doesn't help at all. This is what happens: On the setup page where you have to select the target medium, it says: 141816 MB Disk 0 at Id 0 on bus 0 on ioStor. First of all.. it's a WD Raptor ADFD (74GB).. I used to have it in raid 0 mode - still I wonder why it says 141816 MB here. The harddisk currently is the only drive in the whole system and SATA torage mode is set to AHCI (not RAID, not IDE). Anyway.. it sees a disk. Unfortunately the next line says: ("Setup cannot access this disk.)" Great. So it sees the disk but cannot handle it? why? Installing on a RAID 0 (SATA mode: Raid) works fine. So this is an AHCI specific issue. Any suggestions (apart from installing in IDE mode and switching to AHCI afterwards)?
