Quite handy, Gigabyte issued a small utility that allows you to change the mode of the chipset SATA controller between IDE, AHCI, and RAID (if available), from within Windows itself.
Once you apply changed you will need to reboot obviously as the new interface needs to be detected
Gigabyte's Disk Mode Switch utility works on Gigabyte motherboards based on Intel 6-series chipset (H61, H67, P67, and Z68).
Personally I'd just switch from the BIOS, but if interested you can download the tool right here.
