Using a sata 3 port 0 I believe but would need to double check and yes ACHI is set in BIOS.
Will try using a sata 2 to do the update and see what happens.
Still a lot of jumping through hoops for these OCZ drives!! Seems like this is something that should have been ironed out a while ago or at the very least leassons leanrt form the first gen drives?
That's why it won't update. Change it to IDE... NOT AHCI. Once in IDE mode it will update properly. Make sure to switch back to AHCI and make sure to clear your CMOS after. I strongly advise you follow the steps listed on the OCZ forum for updating firmware.
