Embodiment Construction

[0021] During the startup process of the operating system of the computer device, the CPU first needs to run a boot program, such as the BIOS program, to initialize the specified hardware set. When the CPU runs the BIOS program, it needs to obtain the hardware of the computer device from the CMOS. configuration parameters. Wherein, the specified hardware set refers to a set of hardware that needs to be initialized during the process of starting the operating system, for example, it may include memory, power supply, and so on. In the case of replacing some hardware of the computer equipment (for example, the memory module is replaced, the CPU is replaced), or the BIOS program is upgraded, the CPU restarts, and the configuration information stored in the CMOS will be different from the actual configuration information because it has not been updated in time. Inconsistent, at this time, the CPU will not start normally, so it is necessary to modify the hardware configuration param...

Abstract

The invention provides a CMOS emptying method and computer equipment. The method comprises the following steps: in the starting process of an operating system of the computer equipment, sending a signal to a control device under the condition that a CPU normally initializes a specified hardware set; and under the condition that the control device does not receive the signal sent by the CPU within a period of time, sending a signal to the reset interface of the CMOS, so that the CMOS empties data. By means of the method, the CMOS is automatically emptied under the condition that hardware of the computer equipment is not successfully initialized, and the defect that in the related technology, CMOS emptying is not convenient enough is overcome.

Description

technical field [0001] This description relates to the field of computer application technology, in particular to a method and computer equipment for clearing CMOS. Background technique [0002] In the process of starting the operating system of the computer equipment, the central processing unit (Central Processing Unit, CPU) first needs to run the boot program, such as the basic input output system (Basic Input Output System, BIOS) program, to complete the initialization of the specified hardware set. Wherein, the specified hardware set refers to a set of hardware that needs to be initialized during the process of starting the operating system, for example, it may include memory, power supply, and so on. The hardware configuration parameters required to complete the initialization of a specified hardware set are usually stored in a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS). [0003] In practical applications, some situations m...
