First, save this backup somewhere. If you want to be really
paranoid/safe also save it on external media.

You'll need to get the bios out of the exe. Try all of these:
Then find the file with an appropriate size. It will be the exact
number of bytes as the backup you have made.
Then, recent versions of flashrom automatically verify after writing so
you do not need a little v. A big V would be nice for debugging any
issues that occur.
Now, make sure that you have time (at least a day, maybe more) to leave
the machine running in case the flash fails. If it does fail, it is
likely some software protection that can be disabled with some
investigation (some reverse engineering by a developer, a patch being
written, applied by you and a new flashrom being compiled by you).
Also keep in mind that all flash updates have some amount of risk.
So the command you'll want to run is:
# flashrom -Vw $newfile
where $newfile is the image you find after uncompressing/extracting the
.exe provided by the bios vendor.
Good luck (and please send success/failure reports to this list),
