Background technology
Server is usually made of two parts, and the components of system as directed in addition to being responsible for business processing, further includes BMC
(Baseboard Management Controller, baseboard management controller) part, administrative units of the BMC as server,
Realize the management and monitoring to server system part.Components of system as directed need to be based on BIOS (Basic Input Output
System, basic input output system) operation could be started, BIOS is one group of program being cured in storage chip, it is preserved
The program of the most important basic input and output of server, major function is for the server system part realization bottom, most
Direct hardware setting and control operate.
In the design of existing server master board, system passes through PCH (Platform Controller Hub, platform courses collection
At chip) SPI (Serial Peripheral Interface, Serial Peripheral Interface (SPI)) interface access BIOS.In server
During use, the update of BIOS is a kind of operation often used, such as when BIOS failures or bios version have
When update, it is required for update BIOS.There are mainly three types of the methods of tradition update BIOS, one is being updated by recording device, needs
BIOS storage chips are first removed from plate, then pass through dedicated recording device more new procedures；Second is in operating system
Update realizes that the update to BIOS storage chips operates by running a program on an operating system；The third is that BMC is blocked
