It does. See http://www.freiburg.linux.de/~stepan/bios/

It's not too difficult to work it out. You know where the BIOS is mapped in memory because it's always at the same place (0xe0000 or 0xf0000?), you know what kind of flash chip they use because it's written on the top of the chip, and you know how to erase and write the flash because the manufacturer of the _flash_ publishes docs.
What you might _not_ know is the format in which your BIOS vendor distributes their upgrades. But I doubt it's hard to work that one out, either.
