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.
Claims8
A basic input/output system updating method comprising the steps of:
- dividing a memory in an electronic device into a system program area and a boot program area;
- storing a basic input/out system (BIOS) program in the said system program area such that when a microprocessor of the said electronic device reads the said program, the said microprocessor executes a system initialization sequence of the said electronic device;
- storing an initialization sequence into said boot program area, while the said system program area be destroyed and the BIOS program is lost, a switch is able to be switched to an ON position to connect the said microprocessor to the said boot program area and thereby enables the reading of the said initialization sequence in the said boot program area.
3 As mentioned in claim 1 of the basic input/output system updating method, wherein the said microprocessor, during the said initialization sequence, activates an integrated drive electronics (IDE) interface of the said electronic device, reads a BIOS program stored in the said IDE-interface connected to the said hard disk drive, and records the said BIOS read from the said IDE-interface into the said system program area.
