Recovering the BIOS password from a Panasonic CF-U1 mk2 (AMI Aptio UEFI)

A mess of my own making

While messing with a CF-U1 handheld PC that I bought off ebay I managed to mess up the BIOS and it seems it reverted to previous settings which included an unknown BIOS password, it would however still boot into windows. Since I could still boot windows I was able to dump the bios flash using AFUWINGUI.EXE the version I used was 3.09.03.1462 which is available here:
