Hmm.. I think I had same problem, one of the universal bios packages don't have checksum (zero byte in place of checksum value), I had to load it in xtide configuration program (under virtual machine because it is 16-bit dos program which won't work in 64-bit systems) and then save it to fix the checksum..
