Im thinking that only bios B can be updated. Latest is ver 1.B with improved VGA compatibility improvements.Ħ. Note that current ver 1.7 in Bios A is no longer supported.

I then reset and it booted up still in the A bios and system is operating normally.ġ.Why is it giving me the message of failed bios? this is the first update ever since I assembled the pc and it always booted up with bios A.Ģ. It then started to update and got stuck at 18% and nothing happened for 5mins. I ignored this message and pressed enter since the A bios was the target bios to update. It then shut down after 5 seconds and rebooted like it said it would and the message popped up "Switch to the failed bios rom B and then press any key to continue". Note there was no option to back up bios A.

Then selected the flash bios and ME option and followed all the instructions on the screen. Bios position was left in A as before and then went into M-Flash option. I then proceeded to restart with the flash drive plugged in and enter the UEFI. So I reformatted the flash drive to FAT 32, downloaded latest version 1.B and unzipped and saved the files on the root of the flash drive then I deleted the zip file.
