Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] A method for auditing the BIOS provided by the present invention is mainly used in the technical field of server products, and utilizes the particularity that the server BMC never powers off and is powered on preferentially. When the BMC is powered on, the system powers on the TPM module to help Before the BIOS starts, audit the BIOS.

[0019] like figure 1 As shown, after the server is powered on, the BMC is powered on first, and the TPM module is also powered on at the same time. At this time, the CPU is not powered on. After the BMC is started, the BMC enables the TPM module, and after ...

Abstract

A method for auditing a BIOS, comprising the following steps: (1) after a server is powered on, power on a BMC and a TPM module synchronously and leave a CPU not powered on; (2) after being started, the BMC enables the TPM module and sends, after waiting for a time period for initialization of the TPM module, to the TPM module an audit request instruction for requesting the TPM module to audit a BIOS FW; (3) the TPM module receives the audit request instruction, audits the BIOS FW and sends the audit result to the BMC after completing the audit; (4) when the BIOS FW fails the audit, the BMC does not power on the CPU; when the BIOS FW passes the audit, the BMC first turns off a data channel between the BMC and the TPM module and then powers on the CPU; and (5) after the CPU is started, use the TPM module as a PCIe peripheral. By taking advantages of the particularity that a BMC of a server is never powered off and is always powered on first, a system powers on a TPM module while powering on the BMC, thus helping to audit a BIOS before the BIOS is started.

Description

technical field [0001] The invention belongs to the technical field of server products, and more specifically relates to a method for auditing BIOS. Background technique [0002] In the prior art, the TPM (Trusted Platform Module, Trusted Platform Module) module is inserted in the PCIe slot as a peripheral of the server, and the TPM module can be powered on and the audit function of the TPM module can be used only after the BIOS is started. [0003] The disadvantage of the prior art is that the TPM module can only be used after the BIOS is started, and the TPM module cannot be used before the BIOS is started, and thus the audit of the BIOS cannot be realized before the BIOS is started. Contents of the invention [0004] Aiming at the defects of the prior art, the purpose of the present invention is to provide a method for auditing the BIOS, which aims to solve the problem in the prior art that the BIOS cannot be audited before the BIOS starts because the TPM module can onl...
