鍵盤20，而目前市面上較新型的主機板，南橋晶片（SB) 上更連結有一序列式高等連接技術介面（Serial Advaneed Technology Attachment ’ SATA) 21，是故，該中央處理單 元（CPU) 11必須和該北橋晶片（NB) 121與該南橋晶 7 200818014 片（SB) 122所構成的晶片組（chipset) 之間相互的 配合才能使整個電腦系統正常的運作。

See the first figure, It is a block diagram of each component on a motherboard. As shown in the block diagram, we can clearly see that the motherboard 1 is a system with a central processing unit (CPU) n as the system. The signal is connected to a chipset 12 composed of a north bridge chip (N〇rthBridge Chip 'abbreviation: NB) 121 and a south bridge chip (s〇uthBridgeChip, SB) 122, wherein the north bridge chip (NB) The 121 is interconnected with the central processing unit (CPU) n by a front busbar (FSB) 101; a memory busbar 102 and a main memory (Main Memory) 13 are mutually connected. Connected with an AGP bus 1 〇3 communicates with an Accelerated Graphics Port (AGP) 14 which is connected to a peripheral component (Pcipheral Component Interconnect, pci) by a PCI bus 1 . 15 Interconnected' Also connected to the South Bridge (SB) is an isa (Industry Standard Architecture) interface 16. A Universal Serial Bus (USB) interface π, Π) (Integrated Drive Electronics) The interface 18, a mouse 19 and a keyboard 20, and the newer motherboard on the market, the South Bridge chip (SB) is further connected with a Serial Advaneed Technology Attachment 'SATA 21, The central processing unit (CPU) 11 must cooperate with the chipset formed by the north bridge wafer (NB) 121 and the south bridge crystal 7 200818014 chip (SB) 122 to enable the entire computer system to operate normally. . When the user uses the computer, he or she will use the operating system (Opereating System, 简称s) installed in the computer system, for example: wind〇ws XP, Lmux or Mae, etc. The e(10) body (4) is issued, and then the computer system is controlled to execute the command issued by the user, and finally the result of the computer system execution is displayed on the display by the Jewish system. Therefore, the operating system is the user and the computer line. Communication - a very important interface, by (4) all applications (Applications) such as Word, Ecxel or browser, etc., must be executed on the operating system platform, so when the computer system When booting, it will enter the environment of the operating system first, and the user can execute each (4) program (AppUeati_) on the line. As shown in the first figure, when the computer system starts to operate, usually the operating system The program data and related data are first loaded into a specific address in the main memory 13, and at this time, the central processing unit U sends a certain signal (Ad) Dress signal) through the north bridge chip 121 value recalling body, the main memory 13 transmits a data signal (DataSignal) to the central processing unit u, and the central processing unit 11 can read the system (4) The program data and related data, so that the computer system starts to execute the operating system. However, 'usually only one operating system can be executed in the same computer system', if it is necessary to execute another operating system in the same system, it must be After the computer system is turned back on, you can select another operating system to be executed. For example, the user uses the Microsoft Windows operating system for paper processing, and when the user f wants to use the Macintosh operating system for drawing operations. At the time, the user has to restart the computer to replace the Microsoft Windows operating system with the Macintosh system. This has caused considerable inconvenience and time-consuming costs. In addition, the test host For the manufacturers of the board, it is also necessary for the non-operating system to do it separately, so that it is necessary to increase the main The complexity of the program during the test and the addition of time = therefore 'how to improve this - the lack of improvement, is the main purpose of the development of this case.
