Anyone have any ideas?
I know this is late after 2 years lol but i think i know what you're looking for
AHCI setting you will find under Chipset tab, from there I went to first choice (which is SouthBridge Configuration for me) and then you need to find OnChip SATA Type, under that setting there are choices as Native IDE, RAID, AHCI, Legacy IDE, IDE->AHCI. There, hope i helped
