Problems solved by technology

But this method can not realize the distribution of BIOS file, can only be updated computer when BIOS needs updating, starts network connection and obtains BIOS update upgrade file from server, and server can not send BIOS update upgrade file actively to it, simultaneously, This BIOS update and upgrade method also inevitably interrupts existing applications. In addition, due to the use of TFTP transmission mode, it is also difficult to realize file transfer in a firewall or restricted network

Embodiment Construction

[0036] A BIOS refresh upgrade system and method of the present invention will be further described below in conjunction with accompanying drawings 1 and 2 .

[0037] The present invention mainly uses the existing mainstream out-of-band management architecture standard IPMI2.0 to realize the update of the terminal computer BIOS, and its main work needs to establish a data link between the base board management controller and the BIOS, and execute corresponding instructions in the BIOS. Enables reliable out-of-band BIOS update upgrades.

[0038] The core of the Intelligent Platform Management Interface (IPMI) is a dedicated chip / controller, also called a server processor or a Baseboard Management Controller (BMC). This controller is typically installed on the system motherboard or blade. Together with the BMC, the IPMI firmware forms the basis of the Platform Independent Management Subsystem. This subsystem works regardless of the type or state of the processor, BIOS, or opera...

Abstract

The system comprises: a remote control server end and a terminal computer both comprising IPMI, BMC, and outband NIC. The IPMI of terminal computer comprises: a BIOS update controlling module used to read the fresh flag bit and to decide if the BIOS update file needs to be read and the BIOS needs to be updated. The terminal computer also comprises a update file storing module used to save the BIOS update file and to set the fresh flag bit as ' updating the BIOS'; the BIOS update controlling module deletes the flag bit after updating the BIOS. The remote control server end also comprises a BIOS file transmitting module used for transmitting the BIOS update file to the computer through network.

Description

technical field [0001] The invention relates to the field of computers, in particular to a system and method for refreshing and upgrading BIOS. Background technique [0002] At present, computers are very popular, and due to the rapid replacement of computers, relatively short research and development time, and frequent hardware updates, it is inevitable that hardware or software incompatibility will occur during the use of computers. Hardware or software upgrades. If the hardware or software that needs to be updated is related to system compatibility and stability, most of them are related to the Basic Input Output System (BIOS). Therefore, in order to solve the problem of updating hardware and software, it is necessary to update Upgrade the BIOS. [0003] However, in some large-scale distributed network systems, such as metropolitan area networks, servers, especially rack-mounted In the network system, there are problems related to BIOS upgrades. How to update and maint...
