Patent ID: 7000103

Claim:
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/output system (BIOS) program in said system program area such that when a microprocessor of said electronic device reads said program, said microprocessor executes a system initialization sequence of said electronic device; storing an initialization sequence into said boot program area, wherein when said system program area is destroyed and the BIOS program is lost, said microprocessor, connectable to said boot program area via a switch, enables reading of said initialization sequence in said boot program area; and wherein said microprocessor during said initialization sequence, activates an integrated drive electronics (IDE) interface of said electronic device, reads a BIOS program stored in said IDE-interface connected to a hard disk drive, and records said BIOS read from said IDE-interface into said system program area.
