The BIOS settings are stored in CMOS memory powered by a small battery on the motherboard.

  1. True
  2. False

Answer: True

CMOS (Complementary Metal-Oxide-Semiconductor) memory stores BIOS/UEFI settings (boot order, system time, hardware config) and is powered by a coin-cell battery (CR2032). If battery dies, settings reset to defaults and system clock loses time. Replacing battery restores persistent storage.
