eli5: Why is it bad to unplug a computer when it’s updating it’s BIOS?
In: Technology
The BIOS is the first thing the motherboard accesses in order to start up and eventually access some storage device to load the operating system from.
When overwriting this firmware, if something happened that leaves the firmware in an unusable state, such as a power loss while the firmware is still being overwritten, it’s possible to end up with a firmware that is incapable of functioning
This will lead to a useless motherboard, except in some cases where the chip holding the firmware can be replaced physically.
