Did you Flash from DOS with the included AFUDOS 2.32 ??? Direct Quote from ASUS Site: "Must use new Afudos(2.21) or later revision to flash BIOS." That BIOS is the EXACT same size as the Unmodified ver. 2002 BIOS.
I used the flash tool included in the pack, I don't know what the problem might be... I have a relatively old BIOS version (2006 or thereabouts), and am going to try flashing an intermediate BIOS revision, maybe that will solve the problem.
