Abstract

The invention provides a device and control chip for protecting contents stored in a BIOS chip. The device includes a control chip and one or more access chips, wherein each access chip is connected with the control chip, and the control chip is connected with the BIOS chip; each access chip is used for sending access requests to the control chip, and the control chip is used for receiving the access requests sent by a current access chip; according to the access requests, whether or not the current access chip is allowed to access the BIOS chip is judged; if yes, the current access chip is communicated with the BIOS chip, and if no, disconnecting between the current access chip and the BIOS chip is kept. The device and control chip for protecting the contents stored in the BIOS chip can improve the reliability of files stored in the BIOS chip.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a device for protecting content stored in a BIOS chip and a control chip. Background technique [0002] BIOS (Basic Input Output System) is a set of programs solidified on the ROM (Read-Only Memory) chip on the motherboard of the computer, which stores the most important basic input and output programs of the computer. , Self-test program and system self-start program after booting, so BIOS is the basic guarantee for the normal operation of the server. [0003] Currently, the BIOS chip is directly connected to a Chipset (chipset) chip and a BMC (Baseboard Management Controller, baseboard management controller) chip through an SPI (Serial Peripheral Interface, Serial Peripheral Interface) interface. The Chipset chip and BMC chip can modify the content of the BIOS chip at any time. [0004] It can be seen from the above description that the BIOS chip in the prior art is relativ...
