Abstract:
A dual BIOS program protecting method is provided for protecting a first BIOS program and a second BIOS program of a computer system. Firstly, a flag is switched from a first status to a second status during the refreshing of the first BIOS program. If the first BIOS program is successfully refreshed, the flag is switched from the second status to the first status. If the flag is in the second status when the computer system is booted, a first control signal is generated and the second BIOS program enters a write protection mode according to the first control signal.
