Abstract
THe storage device of an electric equipment (such as notebook computer) is divided into the system program area, which possesses the basic input/output system (BIOS) stored and the area of the bootstrap program area, which possesses the bootstrap program stored. The microprocessor of the electric equipment reads the bootstrap program to start up the system. When the system program area suffers the breakage losing BIOS, the user can change the switch to ON state, making the microproceesor connect to the bootstrap area. Thus, with the bootstrap being read, a storage device connected to the electric equipment is started up. The BIOS stored in the storage device is read out and written to the system program area. Thus, the electric equipment having been lost the BIOS can be still started up.
