Ross its a o6 LBZ with 128 os and the 6 speed alli os is 766. I am using the brand new software that was just released 7.5 i think for vista and the firmware is 2.45. I cant seem to update my firmware because there in not a fsprog when i go to update it anywhere on my computer under the EFI live program folder. I am sure it is something stupid ross and i hate to waste your time but your help is appreciated.
