BIOS or EFI

• BIOS (Basic I/O System) or EFI (Extensible Firmware Interface)
  • A program that is written in ROM
  • Provides the lowest level interface to peripheral devices and controls the first step of the boot procedure
  • BIOS tests the system, looks for and checks peripherals and then looks for a device (floppy, hard disk, or CDROM) to use to boot the system
  • Master Boot Record (MBR) is the sector that the BIOS reads in and starts when a hard disk is used to boot.
