ABSTRACT:
A system and method for automatic booting based on a single flash ROM includes a flash ROM (130) and an address map circuit (120). The flash ROM is stored with a main boot code (1301) in a first address section (1303) and with a backup boot code (1302) in a second address section (1304). The address map circuit connects to a CPU (100) and the flash ROM, and includes a counter (1202) and an address decoder (1201). A related method includes the steps of: (a) a computer being powered on; (b) a CPU of the computer retrieving the main boot code and checking whether the main boot code is corrupted; and (c) the CPU retrieving the backup boot code if the main boot code is checked as corrupted.
