Abstract
The invention is to provide a basic input/output system updating method that divides a memory in an electronic device into a system program area and a boot program area, wherein a basic input/out system (BIOS) program is stored in the said system program area and an initialization sequence is stored in the boot program area. When the initialization sequence in the said system program area is destroyed and the BIOS program is lost, the invention enables a user to toggle a switch to a closed position to connect the said microprocessor to the said boot program area to read the initialization sequence stored therein.
