After executing the bios update file, Windows 10 displays the following messages during the reboot:
1. Bios update failed!
2.Embedded Microcontroller Firmware Update Successful
3. Could not find the firmware image in memory.
I have the exact same issue.
I have replaced the CMOS battery.
Cleared the CMOS.
Removed PCI cards except video.
Still no Luck!
I am able to flash the BIOS all the way back to A12 and back to A16.
But after that, no luck.
I get a bad checksum error!
