Abstract

The invention discloses a personal computer capable of backing up startup data, which is used for backing up an authentication password and a desktop management interface program of a basic input/output system. The personal computer comprises a flash memory, a south bridge chip set and a processing unit, wherein the flash memory is provided with the basic input/output system, the authentication password, the desktop management interface program and a check program; the south bridge chip set comprises a data backup unit; the data backup unit records a restoration program, the authentication password and the desktop management interface program; during the startup of the personal computer, the processing unit operates the check program; if the authentication password or the desktop management interface program in the flash memory is not consistent with that in the data backup unit, the processing unit operates the restoration program; and the authentication password and the desktop management interface program stored by the data backup unit are over-written to the flash memory.

Description

technical field [0001] The invention relates to a data backup device, in particular to a personal computer capable of backing up boot data. Background technique [0002] With the rapid development of personal computers, more and more people will use personal computers to assist their work. In order to ensure the security of data in the personal computer, the personal computer provides multiple confidentiality methods. [0003] The most commonly used one is the verification password function in the Basic Input / Output System (BIOS for short) of a personal computer. The basic input / output system is the first program executed during the operation of a personal computer. Once the authentication password function of the BIOS is enabled, the personal computer will ask the user what the password is when the BIOS is running. If the user enters a wrong password, the basic input / output system will not continue to operate until the user enters the correct password. This will reliabl...
