Facilitation of BIOS flash upgrades. [update-grub]

[Karl Hegbloom]

The System Rescue CD at http://www.sysresccd.org/ has a way to boot a
little FreeDOS system.  I think it could be set up on the hard drive so
that either Grub would offer a menu, or a simple command could be typed
at the grub prompt to start it, hiding it from the default menu.
Perhaps the option should be password protected?

Then, a simple way to copy some files to that little FreeDOS system
could be provided, so that one could download the BIOS flash utility and
new BIOS image, then copy them to that DOS file system, then reboot to
it and upgrade their computer's firmware.

What do you folks think of this idea?  Is it worth doing?  If so, then
how do you think it should be implemented?

I suppose that support for it would need to go into 'update-grub', if it
is to present a menu item.  Even if no menu is to be offered, the
menu.lst template would probably need something for it.

It would be good to have it as an optional package that "Provides" a
virtual package name ("bios-update" ?) so that vendors (VAR) can easily
place a BIOS upgrade on an apt archive server for use by their
customers.  Should that package attempt to edit the DOS file system of a
separate FreeDOS image package, or simply provide the whole thing?

Hmmm... it could install a grub menu item when it's present, and then
you'd simply 'dpkg --purge' it when you have completed a successful BIOS
update.  I think this implies support in 'update-grub'.
