the filename of the "bin" is not importent, but not longer as 8 and no symbols.
i try the asus XT PE bios and i cant unlock the 4 pipelines, but at my first run i use the wrong flashrom version, i think both are nearly the same?
use the ati.x800xt.256.sam..... it works by me with no problems!
i play farcry, doom, cod,.... never have any problems or errors!
i read the ASUS AX800PRO/TVD is 100% similar to the AX800XT/TVD
only the bios and the packing are different
and wenn you have problems flash the backup of your original bios back
