Problems solved by technology

[0005] The present invention aims at the dual BIOS design in the prior art. Although the problem of system startup is solved, in most cases, the initial version of the BIOS is too old, contains major loopholes or has a serious impact on system performance, and is still unfavorable

Example Embodiment

[0019] The present invention will be further explained in conjunction with the accompanying drawings of the specification.

[0020] An intelligent redundant backup method for BIOS in a server system, the specific steps are as follows:

[0021] ①The server is set with dual BIOS, South Bridge is connected to BIOS 1, and BMC is connected to BIOS 2. The server is set with dual BIOS, where BIOS 1 and BIOS 2 are connected to the same input port of 2:1 MUX / DEMUX at the same time, South Bridge and BMC are respectively Connected to the output port of 2:1 MUX / DEMUX, BMC directly controls one of the 2:1 MUX / DEMUX through the SEL signal, and the other 2:1 MUX / DEMUX after the SEL signal passes through the inverter. It can be guaranteed that both South and BMC can access the two BIOS chips without access conflicts; among them, MUX / DEMUX are multiplexers.

[0022] BMC and South Bridge are connected through LPC to realize the information exchange between the two;

[0023] ②After the system starts no...

Abstract

The invention discloses an intelligent redundancy backup method for a BIOS in a server system and belongs to the field of server storage. The intelligent redundancy backup method comprises the specific steps that 1, double BIOSs are arranged in a server, a South Bridge is connected with the first BIOS, and a BMC is connected with the second BIOS; 2, after the system is normally started, the BMC detects the version of the first BIOS through an LPC detection system and checks whether the version of the second BIOS is identical with that of the first BIOS, if yes, starting operation continues, and if not, a user is informed by the BMC of the fact whether the version of the second BIOS is updated synchronously; 3, when the version of the second BIOS is updated, the BMC reads the content of the first BIOS under the condition that the system is in the standby state, the BMC synchronously updates the content to the second BIOS, the content is used as the redundancy of the first BIOS, and it is guaranteed that the version of the second BIOS is synchronous with that of the first BIOS. By the adoption of the intelligent redundancy backup method, the version can be intelligent switched to the current BIOS version instead of an initial version, and the reliability of the system is guaranteed to the maximum extent.

Description

technical field [0001] The invention discloses an intelligent redundant backup method, which belongs to the field of server storage, in particular to an intelligent redundant backup method for BIOS in a server system. Background technique [0002] BIOS is an essential and important part of the server system. Once there is a problem with the BIOS, the system will not be able to start normally, and the performance of the system is largely inseparable from the BIOS. In general, server manufacturers will regularly release new versions of the BIOS program to correct bugs in the original system or optimize the performance of the original system. At this time, the user only needs to upgrade the BIOS program. However, the traditional upgrade method is implemented by replacing the BIOS chip, that is, offline upgrade or online upgrade under the shell. However, the offline upgrade method needs to disassemble and install the hardware again, which is very troublesome and inconvenient. I...
