Problems solved by technology

[0002] At present, in server management, because the server needs to use the latest hardware, the hardware that can be recognized by the BIOS (Basic Input Output System) at the factory cannot perform the latest hardware after a period of time. Identification and application, so it is necessary to update the BIOS of the server to the latest version of BIOS to support the identification and use of new hardware. Refreshing the BIOS is very dangerous. Once the wrong BIOS file is refreshed, the machine will not start. In severe cases, it may cause damage to the BIOS chip on the server
At the same time, due to the long release process of the BIOS file, it is very likely that the file is damaged and the BIOS file cannot be started.

Embodiment Construction

[0021] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0022] Please refer to figure 1 , the figure shows the BIOS startup principle in a method for verifying a BIOS refresh content of the present invention, such as figure 1 As shown, in a preferred embodiment of the method of the present invention, the computer host (such as a server) first copies the BIOS file to the address space of the specified range in the memory after starting up (referring to turning on the power), and then the computer will jump to The first execution address in the specified range of this memory (usually at 0xFFFF0) starts to execute the code, this address is the start execution address of the BIOS, and the content in the BIOS file updated to the machine is consistent with it, so the method of the present invention is Copy the content of the new BIOS file into the address space of the specified range in the aforementioned ...

Abstract

The invention discloses a verification method of BIOS refresh content, which comprises the following steps: a virtual machine is built in a computer which awaits to update system BIOS through using half virtualization technology, the virtual machine is started, and the content of a new BIOS file is copied to address space of a designated range of a memory of a computer host. The computer host is started through using the content in the new BIOS file, and a half virtualization operation system is operated based on a hardware platform which is same to the computer host, thereby further obtaining whether the content of the new BIOS file is correct and safe through verifying whether a virtualization operation system which uses the content of the new BIOS file normally operates.

Description

technical field [0001] The invention relates to a security verification method for file content update in a computer system, in particular to a BIOS refresh content verification method for performing security verification on the update of BIOS file content in a computer system. Background technique [0002] At present, in server management, because the server needs to use the latest hardware, the hardware that can be recognized by the BIOS (Basic Input Output System) at the factory can no longer be used for the latest hardware after a period of time. Therefore, it is necessary to update the BIOS of the server to the latest version to support the identification and use of new hardware, and the operation of refreshing the BIOS is very dangerous. Once the wrong BIOS file is refreshed, the machine cannot be started. In severe cases, the BIOS chip on the server may be damaged. At the same time, because the release process of the BIOS file is long, it is very likely that the file...
