Abstract

The invention provides a circuit system based on the standby function of a BIOS chip and a design method thereof. The circuit system comprises a PCH, a main BIOS, a standby BIOS, a Mux chip and a CPLD. that PCH and the main BIOS chip is connected through the SPI signal line, One end of the Mux chip is connected with a standby BIOS chip through a SPI signal line, the other end is respectively connected with a PCH chip and a CPLD end, and the other end of the CPLD is connected with the PCH chip for LPC signal transmission. The Mux chip is connected with the standby BIOS chip through a SPI signalline, and the other end is respectively connected with a PCH chip and a CPLD end. As that standby BIOS is arrange in the embodiment of the invention, When the primary BIOS fails to work, The system can be switched to the standby BIOS so as to enable the system to continue to work normally, thereby increasing the utilization rate of the system and reducing the labor cost caused by dispatching maintenance personnel to replace the defective BIOS on the spot, so as to avoid the system from being delayed and unable to continue operation when the BIOS chip is in trouble, and reduce the maintenancecost.

Description

technical field [0001] The invention relates to the technical field of server circuit design, in particular to a circuit system based on a backup function of a BIOS chip and a design method thereof. Background technique [0002] In today's computer industry, BIOS is an indispensable piece. It is a set of programs solidified on a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, system setting information, and self-test after startup. Programs and system self-starting programs. Its main function is to provide the computer with the lowest and most direct hardware setting and control. [0003] The BIOS program is generally stored in the motherboard ROM (read-only memory chip), and the program will not be lost even after the computer is turned off or powered off. It is stored in the BIOS chip, which is a rectangular or square chip on the motherboard, and can only be set when the computer is turned on. ...
