Where do you see the results of the "ACC" setting? CPU-Z?

It needs the support in the BIOS. Jetway made that board and mine unlocked months ago. I was the early adapters of the X2 550 and I had the Jetway Ultra 07 6 months before that so everything came together well. Look for the latest BIOS from Sapphire or even write to them. Be forewarned, the support is close to zero and flashing those boards can be very tricky. It could kill your board.

I use two floppies to flash - first contains the DOS boot files and the second contains the BAT, flash EXE and then the BIN file.
