Just for the record: we've upgraded CD burner firmware, and it works by running some silly little program on DOS. No media involved. We've updated/modified harddisk drive firmware. Same procedure: vendor specific commands, and voila! (We're currently banging the hardware to do this, possibly we might port to some passtrhough thingy later on) I have vendor confirmation that turning on some consumer electronics while holding a specific key combo will make the device boot (some stage-2 boot) from the inserted CD instead of the firmware inside. They use this to boot the "diagnostics" CD, but an "update firmware" CD could obviously be made.
