It should be noted that best case here is you end up with two working
motherboards + BIOS chips. Worst case is one dead motherboard + two
dead BIOS chips. Where you will land on the continuuum is hard to
predict in advance. This was (reasonably) SOP on Sun machines, where
the NVRAM chip, which also held the RTC + a battery, used die after a
few years, if you didn't have a spare handy. But the Sun NVRAM chip was
of a physically different format, and was easier to hot swap than a
current PC ROM BIOS chip.
