Description of the invention (2)

Dr lve Electronics (abbreviation: iDE), Small Computer System Interface (abbreviation: SCSI), Network Interface Card (...) The basic input-output system is the part we want to explain, because the computer startup process is performed under the control of the system's basic input-output system. The booting process of the system's basic input-output system is generally stored in the ROM of the motherboard. Therefore, the booting process will not disappear even after the computer is turned off or power is lost. The first basic concept is the storage address of the memory. Usually, a memory with a certain memory capacity is installed in the computer. In order to facilitate the central processing of the computer to access it, each byte of these memories is I have an address. For example, the address range of 32 megabytes (32MB) is expressed in hexadecimal numbers, that is, its storage address is from 0 to 1FFFFFFH, and the low-end 1MB memory of 0 to FFFFFH is very special because For a 32-bit processor, the maximum amount of memory that can be directly accessed is only 1MB '. Therefore, the 1MB low-end 64 kilobytes (KB) is called basic memory, and the storage address is A0. 0 0 0H ~ BFFFFii is reserved for the use of the graphics card. In addition, the storage address is reserved by C0 0 0 0 H ~ FFFFFH is reserved for the basic round-in-output system of all hardware of the computer. The basic input-output system of the system generally occupies the last 64KB or more, and the basic input and output system of the graphics card is generally stored at the addresses of C000000H ~ C7FFFH, and the basic input / output system integrated with the electronic drive interface is stored at the addresses of C8000H ~ CBFFFH Office.

In this process, the big card usually displays some 31b hearts on the display screen, such as: the manufacturer, the type of graphics chip, and the capacity check is the first daytime surface we usually see when we turn on the machine. Once the screen is almost flashed, some of the basic input and output of the graphics card all use the delay function so that the user can clearly see the displayed information. The basic I / O system of the system will look for the basic I / O system programs of other hardware. After finding the same, the initialization code inside the basic I / O system of these hardware will be called to initialize the hardware. "/ Step 4 ·· After finding all the basic hardware I / O systems of other hardware, the 'System Basic I / O System will display its own startup screen, which includes the type, serial number and version number of the system's basic I / O system. At the same time, at the bottom left of the display, the motherboard information code will appear, including the version date of the system ’s basic input and output system, the motherboard ’s control chipset model, the motherboard ’s identification code, and the manufacturer ’s code.
