These bios updates are untested as I was looking for a RevA1 bios and found these on a Japnanese web site.
Rev A2,A3,B5,B6,B7,C2,C3,D1 and D4 BIN files are included, as well as AWDFLASH bios flasher and english instructions in DOC format.
The following files are found inside the driver download file.
