Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in detail below in conjunction with the embodiments. It should be noted that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] The server dual BIOS Flash control system and method are composed of a CPLD chip, a BMC chip, a PCH chip, an IOExpander chip, a Switch chip and a dual BIOS Flash chip; the CPLD chip and the PCH chip are respectively connected to the BMC chip through a GPIO bus, and the The IO Expander chip is connected to the BMC chip through the IIC bus. At the same time, the PCH chip and the IO Expander chip are also connected to the Switch chip, and are connected to the dual BIOS Flash chips through the Switch chip.

[0025] The CPLD chip is used to control the power-on sequence of the hardware circuit of the ...

Abstract

The invention particularly relates to a dual-BIOS Flash control system and method of a server. The dual-BIOS Flash control system and method of the server involve a CPLD chip, a BMC chip, a PCH chip,an IO Expander chip, a Switch chip and a dual-BIOS Flash chip; the CPLD chip and the PCH chip are each connected to the BMC chip through a GPIO bus, the IO Expander chip is connected to the BMC chip through an IIC bus, and meanwhile the PCH chip and the IO Expander chip are further connected to the Switch chip and connected to the dual-BIOS Flash chip though the Switch chip. By means of the dual-BIOS Flash control system and method of the server, not only can redundancy BIOS Flash switching be provided when the BIOS Flash function is not normal, it is ensured that the server is started normally, and the overall reliability is improved, but also the selection of BIOS Flash during last-time starting can be remembered, therefore the overall switching speed can be improved, and the time of starting up is shortened.

Description

technical field [0001] The invention relates to the technical field of management boards, in particular to a server dual BIOS Flash control system and method. Background technique [0002] In the server system, Firmware programs such as BIOS image, ME image, and LAN image are burnt into a Flash chip, which is called BIOS Flash. After the mainboard is powered on, the firmware in the BIOS Flash provides the most basic hardware initialization of the server and the necessary procedures for peripheral device control. In addition to providing the server with the lowest and most direct hardware settings and controls, the BIOS also provides some system parameters and device information to the operating system. [0003] To sum up, BIOS is a bridge between the underlying hardware and the upper operating system, and is a key part of the normal operation of the server. If the BIOS Flash fails, it will directly cause the service to fail to run normally. [0004] In the prior art, the ...
