howdy
, first off let me just say im not a usual member here, i actually use overclockers.co.uk forums, i built them a util to make it easy to flash the GTO2 because the techpowerup guide and others are terrible lol,
anyway, this is a simple procedure for X800GTO2 ONLY. And yes it works under all microsoft operating systems and i believe uner linux as well but im not 100% on that being as i havent tested it on that platform.
download this ISO Unzip it and burn to CD / DVD (if you have nero, open it, close the wizard and from the record menu select burn image then select the ISO, if you have easy CD creator, i dont have a clue )
CLICK FOR GTO2 MOD!!
GTO2 Mod File Mirror
step 1 boot from CD\DVD by changing the bios boot order to boot the optical drive of your choice.
step 2 Select the menu option of your choice, it will confirm a succesful flash once done.
step 3 Enjoy!
Recovering from a bad flash....
step 1, install a pci graphics card,
step 2, boot from DVD\CD
step 3, select option 2 from the boot menu
Step 4 Reboot and Retry the flash.

All i ask is that you post how you get on and if you use this anywhere else, please give me credit for it as it wasnt easy!! i havent seen an autoexec.bat for about 6 years let alone wrote one
p.s. let me know how you get on

Edit: Important. The Initial Flashrom Had An Error When Flashing Back To 12 Pipes, This Has Been Fixed But You Will Need To Redownload The Iso And Make A New Boot Cd. Sorry For The Trouble.
