[0038] The present invention provides a second embodiment as follows.

[0039] Figure 8 Shown is a structural block diagram of a computer system according to the second embodiment of the present invention. Please refer to Figure 8 , since the space required by the state register 310 is not large, in the computer system 800 provided in this embodiment, the state register 310 can be configured in the chipset 304 . Even in some other embodiments, the state register 310 can be realized by utilizing the space in the south bridge chip 314 . Therefore, the computer system 800 provided in this embodiment does not increase additional hardware costs.

[0040] To sum up, since the boot block in the BIOS of the present invention is divided into a fixed data segment and an updateable data segment. Therefore, even if the BIOS update fails, the computer system can still be powered on by the data in the fixed data section for remedial measures. In addition, since the status register ca...

Abstract

The invention relates to a BIOS structure which can be suitable for a computer system and is provided with a turn-on block, wherein the turn-on block can be at least divided into a fixed data section and an updatable data section. When the BIOS requires updating, a program code of the BIOS can be updated from the updatable data section. In addition, the computer system can determine to execute the program code of the BIOS from the fixed data section or the updatable data section according to a state value when requiring executing the program code of the BIOS.

Description

technical field [0001] The present invention relates to a structure of a basic input and output system, and in particular to a structure of a basic input and output system which divides a boot block. Background technique [0002] figure 1 Shown is a structural block diagram of a known computer system. Please refer to figure 1 , a known computer system 100 includes a central processing unit 102 , a chipset 104 , a memory 106 and a basic input output system (BIOS) unit 108 . The CPU 102 is coupled to a chipset 104 and is coupled to a memory 106 and a BIOS unit 108 through the chipset 104 . [0003] Chipset 104 includes north bridge chip 112 and south bridge chip 114 . Wherein, the north bridge chip 112 is coupled to the CPU 102 , and the CPU 102 is coupled to the memory 106 and the south bridge chip 114 through the north bridge chip 112 . In addition, the south bridge chip 114 is coupled to the BIOS unit 108 . When the computer system 100 is turned on, the CPU 102 can lo...
