Abstract

Embodiments of the present invention provide a BIOS chip switching method and a baseboard management controller, which are used to quickly solve the problem that a server cannot be started due to a BIOS chip failure. The method includes: a baseboard management controller BMC receives an operation instruction, the operation instruction is a start instruction to a server, and the server includes a first BIOS chip and a second BIOS chip; the BMC monitors whether the operation instruction is received within a first time period The first signal sent by the first BIOS chip, and whether the second signal sent by the first BIOS chip is received within the second duration, the first duration and the second duration are different durations, and the The second duration is the duration after the first duration; if the BMC does not receive the first signal within the first duration, or the BMC does not receive the first signal within the second duration two signals, the BMC switches the first BIOS chip to the second BIOS chip to restart the service.

Description

technical field

[0001] The invention relates to the communication field, in particular to a BIOS chip switching method and a base board management controller. Background technique

[0002] With the continuous development of IT technology, the security, reliability and availability of servers are becoming more and more important. The startup of the server mainly depends on the driver program in the BIOS (Basic Input / ouput system) chip on the server, which stores the most important basic input and output programs of the computer, the self-test program after power-on and the system self-starting program, providing the computer with the most Low-level, most direct hardware setup and control. If the BIOS chip is physically damaged or the BIOS chip program is damaged, the server will not start normally.

[0003] When the BIOS chip is damaged or the BIOS chip program is damaged, it is necessary to replace the chip or reprogram the BIOS program to ensure that the system starts nor...
