If the motherboard doesn't have a good recovery mechanism, a flashed BIOS will effectively invalidate the motherboard as the BIOSes are soldered-on Flash theses days.
The key is a separate jumper/etc for a recovery bios, as this will prevent the "Flash the bios" attack from doing perminant damage, as one can flip the jumper, boot the machine, and reflash the main BIOS back into a known good state. Some motherboards have this, others don't.
The other problem with Bios flashing is that it is fairly Bios and motherboard specific. But as there are generic "flash the BIOS" tools for updating large classes of motherboards, much of the information could be extracted for an "attack the BIOS" tool.
Yet Bios-flashing does look like a more-than-plausible mechanism to cause lots of damage. Someone sholud maliciously flash Orin's computer and see how HE likes it.
