I need to enable AHCI on my PC. It's running Windows 7 Pro on an ASUS IPIBL "Benicia" mainboard. I folled the instructions to modify the registry at computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci & iastorv. Nada. When I change the BIOS from RAID to AHCI, Windows goes into endless reboot.The windows logo graphic doesn't even finish drawing one pane. It's a pain in the kiester to have to reset BIOS everytime I need to use the second drive. What gives? The main drive is WD 160GB HDD. I basically trying to make a hackintosh using a second bare drive, which is a story unto itself.

If you have any RAID 0 array, you must set SATA=RAID or you're going to ruin your array.
Did you tried to set SATA=AHCI on BIOS then boot in safe mode (F8)? As it boots without drivers, you can look at device manager to check if there is something missing. Then try to reboot normally.
