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...
