Abstract

The invention provides a method and device for clearing a CMOS of a server mainboard, and the method comprises the steps: obtaining an instruction for clearing the CMOS of the mainboard, and judging the state of a current server system based on the instruction; if the state is a working state, ignoring a clearing instruction; if the state is that the south bridge is powered on and the starting action is not carried out, outputting a low level to a reset pin of the south bridge, and outputting a high level after keeping for a set time period; and after the system is started, completing the CMOS clearing operation. By controlling the GPIO output level of the CPLD in the server case, the mainboard CMOS is cleared, and before clearing operation is carried out, judgment on the state of the server is added, so that the risk of data loss in the normal running state of the server is avoided.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a method and a device for clearing the CMOS of a main board of a server. Background technique [0002] With the rapid development of computer technology, the trend of informatization and intelligence in the current society is getting faster and faster. As the core equipment of the information system, the server has high reliability and stability, and the application scenarios and market demand are increasing. [0003] BIOS (Basic Input Output System, Basic Input Output System) is the bottom program of the computer. It is solidified in a read-only memory chip. Users can perform some basic settings on the server through BIOS, and CMOS is used to save the hardware configuration of the current system. And the user's setting parameters for the BIOS. [0004] In the process of production, testing, debugging and after-sales maintenance of the server, it is often necessary to clear the ...
