After updating to latest bios there is a new option in Bios setup menu called the “SATA AHCI mode”, does this mean Intel ICH8 supports AHCI function?
Only Intel Southbridge chipset model names that include a R/DO/DH will support AHCI and RAID functions. The function ICH8AHCI can only be enabled under Vista. If you are using Windows XP/2000 please disable the function “SATAAHCI mode” in bios.
