PROBLEM TO BE SOLVED: To reduces cost of a mother board, and at the same time, to provide advantages of a conventional dual BIOS system. SOLUTION: The external basic input/output system (BIOS) device for a computer includes an external memory module and a mother board pin interface. A backup BIOS is stored in the external memory module. When a main BIOS is damaged, the external backup BIOS can replace the main BIOS to execute power-on procedures of the computer. The backup BIOS can also recover correct data to the damaged main BIOS. The external backup device needs to be installed only when a severe error occurs in the main BIOS. COPYRIGHT: (C)2008,JPO&INPIT
