Intel ICH7 datasheet? AFAIR it was described there. Some other vendors allow enabling AHCI just via one of standard AHCI registers, but Intel doesn't. If SATA is not configured as AHCI or RAID by BIOS via custom register, standard AHCI registers are not available. -- Alexander MotinReceived on Sun Nov 15 2009 - 21:40:17 UTC
