[BALUG-Talk] Options for booting windows to update BIOS?

[Matt Harrington]

I have some Intel and Supermicro motherboards which need upgraded
BIOSes, and the BIOS update utility for at least one motherboard is
Windows-only.  I believe I went down this path a few years ago by
burning a FreeDOS CD, but I seem to remember it being a hassle.  Maybe
I wanted to run the executable from a USB stick, and the bootdisk I
used didn't support USB.  I forget.

Anyhow, what's the current state of affairs when it comes to upgrading
BIOSes on systems which don't have Windows?  Something like a LiveCD
of XP would be great.  Lots of options turn up in Google, but it's not
clear which way to go.
