epu6 engine is a power saving program and turbov is an overclocking program. both safe to uninstall if you dont want to use them
latest BIOS version for the P6T is 1004.ROM
download it from the asus website and put it on a usb flash drive

in the bios go to tools and and theres an option in there to run ez flash, run it and select the flash drive you have the new bios on and run. simple as that
Much appreciated, thanks. I'm starting to feel like a bit of an idiot now, is a flash drive different from a usb memory stick? Also, could I do this using a portable usb hard drive.
