Request Unlock AHCI for Gigabyte GA-G31M-ES2L (Rev.2.3)

Guys, could you tell me - has this motherboard (GA-G31M-ES2L (Rev.2.3)) possibility to change HDD mode from IDE to AHCI??

If it's posibly - could you modified the lastest BIOS so that the BIOS supports ACHI mode.

for Administrator: I have started the same theme in another forum by mistake (_http://www.bios-mods.com/forum/Thread-Gigabyte-GA-G31M-ES2L-Rev-2-3-AHCI-Request). Could you delete that theme.

Thank you for your attention to the problem.
