It can also reimage your computer’s firmware even if it’s powered off, so if it’s still plugged in, MINIX can still potentially mess with your computer’s settings.

The lower the number your program runs at, the more access they have to the hardware. Operating systems run on ring zero, but MINIX runs on ring -3.
