ABSTRACT:
A method and system for updating a boot block of a Basic Input/Output System (BIOS) program in an electronic device to prohibit write processes to the boot block while realizing update of contents stored therein. First, at least one content segment that requires update is recorded in an initialization content stored in the boot block of the BIOS program. The content segment defines a data storage address for storing update data associated with the content segment. Then, at least one update block of the BIOS program is established for storing at least an update data, the update data being stored according to the data storage address defined by the content segment in the boot block of the BIOS program. When the electronic device is turned on, initialization is performed using the update data obtained from the update block of the BIOS program based on the data storage address defined by the content segment.
