Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] Referring to the figure, one embodiment of the present invention includes the following operations:

[0026] When starting the computer, first perform step 1; detect whether there is a BIOS file for backup in the HPA, if there is no backup BIOS file in the HPA; then perform step 2, otherwise perform step 3; the specific operations include:

[0027] Open the HPA, and back up the information stored in the BIOS module on the motherboard to the HPA in the form of a BIOS file, and close the HPA (not shown in the figure);

[0028] The above-mentioned conditions for updating and backing up the BIOS include:

[0029] a. Bootblock detects that: BIOS is not backed up;

[0030] b. Bootblock finds that there is a BIOS upgrade flag.

[0031] When starting the computer, first check whether there is a BIOS file in the BIOS backup, if there is no back...

Abstract

The invention is a BIOS automatic recovering method based on harddisc protection space, as the computer starts, firstly detecting if there are BIOS files backuped in HPA: if no, backup the BIOS files in the HPA; further booting the BIOS: if the boot fails or the BIOS has been upgraded, use the backup BIOS files in the HPA to recover the BIOS modules. It implements BIOS safety protection; provides more reliable BIOS upgrading means; the BIOS data is stored in the HPA, uneasy to be destroyed; because it only needs the harddisc, it can in time and reliably recover the BIOS; it need not display in the automatic repairing course, needs no input device and also reduce the trouble in user interference and operation.

Description

technical field [0001] The invention relates to a method for automatically restoring a computer's Basic Input / Output System (BIOS for short), in particular to a method based on a BIOS file backed up in a hard disk protected area (Host Protected Area, HPA for short), by starting the computer The method for detecting BIOS and automatically repairing or upgrading BIOS belongs to the technical field of computer security. Background technique [0002] With the popularity of computers, the competition in the computer industry is becoming increasingly fierce. Computer hardware is constantly upgraded, and the accompanying software modules are also upgraded. As far as computer motherboards are concerned, the BIOS module is the core software module that controls the work of the motherboard. However, due to the frequent replacement of motherboards, the development and testing cycle of motherboard BIOS is shortened, and the potential defects of BIOS modules are also increasing. In add...
