eli5: Why is it bad to unplug a computer when it’s updating it’s BIOS?
In: Technology
BIOS (loaded into the RAM) is doing the BIOS update. It wipes the little flash memory chip that stores it and starts rewriting it with the new. If the computer is shut off, the RAM is emptied and the old BIOS is lost, leaving only the nonfunctional half-written one on the flash chip.
