Description

BIOS setting method

technical field

The present invention relates to a data processing technology, and more specifically, to a basic input and output system setting method.

Background technique

BIOS (Basic Input Output System) represents the basic input and output system, which belongs to embedded software. The product features are stored in the form of firmware (Firmware) in hardware devices or systems such as information, communication, and consumer electronics products. , control processing, man-machine interface, application program and other functions, use software to increase the additional functions and value of hardware, and produce the cost saving effect of hardware softwareization. Compared with operating system or application software, it has a closer relationship with hardware Closely, it is in charge of the settings of the central processing unit, memory, boot sequence, etc., and is the key to determining whether the hardware functions can be fully utilized. In addition, BIOS also provides the most reliable security protection mechanism to prevent unauthorized use of the computer.

When the computer is turned on, the BIOS is executed from the flash memory on the circuit board, and will sequentially initialize the chipset and memory subsystem, and then the BIOS itself is decompressed from the flash memory to the system's main memory. memory, and execute from there. The BIOS program code of the PC also includes diagnostic functions to ensure that certain important hardware components, such as keyboards, disk drives, I/O interfaces, etc., are functioning properly and initialized properly. Almost all BIOSes can optionally perform a setup routine for the CMOS memory; that is, store user-defined setup data (time, date, hard disk details, etc.) that the BIOS will access.

In today's practical application of BIOS, after entering the BIOS setting mode, the user can choose to set the fan speed, energy saving control, overclocking setting, and choose which device to boot first, such as optical drive, hard disk, floppy drive, flash and etc., this feature is especially useful for installing an operating system. However, after the above-mentioned BIOS sets the boot sequence or other configuration settings of related items, the system will restart regardless of whether the above-mentioned BIOS settings are saved, and the POST (Power On Self Test) will be performed again. ), execute related startup programs such as initializing Option ROM, and finally enter the operating system loading operation. And in fact, although some settings in the BIOS have been modified, after exiting the configuration setting mode, the POST program can still be executed without rebooting. However, in the existing BIOS setting mechanism, no matter which setting in the BIOS is modified and stored, it must be restarted after jumping out of the BIOS setting mode. In the case of the aforementioned BIOS setting modification that does not affect the POST program , obviously a waste of reboot time.

To sum up, how to provide a basic input and output system setting method, so as to solve the problem that no matter modifying any BIOS setting content, the system needs to be restarted, which will lead to time-consuming booting process, and has become an extremely important issue at present. .
