My machine is running the latest BIOS, well, the very latest image
from Gigabyte was a Beta version that required a univeral programmer
to recover the motherboard.  I don't have access to a universal
programmer any more, so I'm a bit reluctant to try this image again.

Is there anything else that can be done to fix this (appart from
downgrading to 4.9).
