GA-EP31-DS3L (rev. 1.0) Storage drivers

Hello.The motherboard GA-EP31-DS3L (rev. 1.0) does not have AHCI in BIOS. Do I need to install any driver and which one?

OS: win 7 pro 64-bit
Drive ssd adata SU800

G31 Chipset generally uses the base ICH7 (82801GB) which is NOT AHCI compliant.
Other variations like ICH7R/DH/ will have it.

Just install the Intel Chipset drivers v9 from here:
