Abstract

The invention discloses a server BIOS flash memory chip protection circuit and a server. The circuit comprises a chip slot, the chip slot is provided with a power supply pin position and a grounding pin position, and the grounding pin position is grounded; a BIOS (Basic Input / Output System) flash memory chip, wherein the BIOS flash memory chip is inserted into the chip slot; a positive temperature coefficient thermistor, the first end of the positive temperature coefficient thermistor is connected with a power supply, and the second end of the positive temperature coefficient thermistor is connected with the power supply pin so as to supply power to the BIOS flash memory chip through the positive temperature coefficient thermistor. According to the scheme, the positive temperature coefficient thermistor is connected in series between the power supply pin of the chip slot and the power supply, so that overcurrent protection is realized when the BIOS flash memory chip is short-circuited, the BIOS flash memory chip is protected, the positive temperature coefficient thermistor does not need to be replaced repeatedly, the structure is simple, and excessive layout space is not occupied.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a server BIOS flash memory chip protection circuit and a server. Background technique [0002] The built-in BIOS program in the BIOS flash memory core (a set of fixed programs burned into the motherboard's flash), includes the most basic input and output programs for server work, self-test programs after power-on, and system self-start programs. The main function of the BIOS flash core is to provide the computer with the lowest and most direct hardware setting and control. Therefore, the initial start-up of the server is inseparable from the self-test of the BIOS code. On the server, the code of the BIOS and BMC is burned in the flash. The first step of starting the server is to load the BIOS to perform a self-test of the system hardware. This is a normal server. The first step to start. [0003] In the process of server design and production, it is necessary to continuously up...
