Skooma, here you are modede to 16 pipes BIOS. Flash it with atiflash using the following command line: atiflash -f -p -newbios 0 bios16.bin
Or you can use my automated bootable flash utility on CD image:

Download also the flashing instructions. You have to use the main utility because it contains your BIOS (not ver.1 or ver.2)
Success
