== Overview ==
Basic Input/Output System (BIOS) standard defines firmware interface. The fundamental purposes of BIOS is to initialize and , test system hardware components, and load a bootloader or operating system from mass memory. BIOS also provides an abstraction layer for hardware, a consistent way for application programs and operating systems to interact with the keyboard, display, and other input/output devices.
* BIOS code is stored in non-volatile SNOR flash memory onboard and accessed by a platform during power up phase.
