When the boot data of the master boot record (MBR) is different from the backup boot data, the basic input/output system overwrites the backup data into the master boot record (MBR), and if the boot data of the master boot record (MBR) is the same as the backup data the basic input/output system turns on one of the operating systems of the host device through the boot sector.

Description

Booting method and booting system with automatically repairing booting magnetic area

The present invention relates to a method for repairing a booting program of a host device, in particular to a booting method with automatically repairing a booting sector and a booting system thereof.

Generally speaking, the first action to be executed when the host device is turned on is to start the Basic Input Output System (hereinafter referred to as BIOS); among them, when the BIOS starts to execute, the computer device is first booted and self-tested To ensure that the hardware equipment of the computer device can operate normally, after the boot self-test is over, the BIOS will notify the computer device and load the first sector of the hard disk (ie, the main boot sector), and its main boot sector The data inside will be loaded to the location of memory 0x7C00 for execution, and then loaded into the boot sector provided by an operating system to enter the operating system.

At present, many boot-type computer viruses mainly damage the main boot sector, so that after the data in the main boot sector is damaged by the computer virus, the computer device cannot start normally. In order to repair the computer device to boot normally, a recovery disc can be used to boot, after entering the BIOS of the computer device, select the recovery disc to boot, and then use the backup recovery data of the recovery disc to restore the boot data of the computer device.

However, in the existing host device, the recovery disc is no longer a basic equipment. Therefore, if you want to back up and restore data, you need to prepare another disc to back up the boot data, and if the user does not back up the boot data after a period of use, Therefore, the host device cannot be restored, and the operating system of the host device must be reinstalled, which not only causes trouble for the user, but is also time-consuming and labor-intensive.

Therefore, in view of the fact that the boot data in the boot sector needs to be restored by a recovery disc, the inventor of this case tried his best to research and create, and finally developed a boot method with automatic repair of the boot sector and boot of the present invention. system.

The present invention provides a boot system with automatic repair of the boot sector, which is mainly composed of a flash read-only memory and a control unit; wherein the flash read-only memory system is provided with a basic input and output system, and the flash The flash read-only memory system has a storage area. In this way, the boot data of a boot sector is automatically backed up in the storage area through the basic input output system. At the same time, the present invention also proposes a boot method with automatic repair of the boot sector. When the boot data of the boot sector is different from the backup boot data, the basic input output system overwrites the backup data into the boot sector. If the boot data of the boot sector is the same as the backup data, the The basic input output system starts an operating system of the host device through the boot sector.

Therefore, in order to achieve the above-mentioned object of the invention, the inventor of this case proposes a boot system with automatic boot sector repair, which is set on a motherboard of a host device, and the motherboard is provided with a storage device; wherein, The storage device has an operating system and a boot sector, and includes: A flash read-only memory is a storage device installed on the motherboard and coupled to the motherboard, and stores a basic input output system; wherein the flash read-only memory system has a storage area, Used to store a boot data; and A control unit is installed on the main board to enable the basic input output system to store the boot data of the boot sector in the storage area; Wherein, the boot data of the boot sector is backed up to the storage area through the basic input output system, so that the storage area stores a backup data; Among them, the boot data of the boot sector is compared with the backup data of the storage area through the basic input output system; Wherein, when the boot data is different from the backup data, the basic input output system updates the backup data to the boot sector; Wherein, when the boot data of the boot sector is the same as the backup data, the basic input output system starts the operating system of the host device through the boot sector.

In order to achieve the above-mentioned purpose of the invention, the inventor of this case proposes a boot method with automatic repair of the boot sector, which includes the following steps: (1) Install a control unit in a host device with a boot sector, and use the control unit to control whether to access the basic input and output of a flash read-only memory installed on a motherboard of the host device System, if you need to enter the basic input output system, perform step (2), if you do not need to enter the basic input output system, perform step (4); (2) Use a setting unit of the control unit to set whether a backup boot data of the basic input output system needs to be updated, if the backup boot data needs to be updated, go to step (3), if not, go to step (6) ； (3) Update the backup boot data of the basic input output system through the control unit, so that the new backup boot data of the basic input output system is updated to the boot data of the current boot sector, and the new backup boot data is stored in the Perform step (1) after flashing a storage area of the read-only memory; (4) Through a comparison unit of the flash read-only memory, whether the 512 bytes of the boot data of the boot sector is consistent with the 512 bytes of the backup boot data of the basic input output system. If the 512 bytes of the data are consistent with the 512 bytes of the backup boot data, perform step (6), if the 512 bytes of the boot data are not consistent with the 512 bytes of the backup boot data, perform step (5); (5) Overwrite the backup boot data stored in the storage area to the boot data of the boot sector of the host device through an update unit of the flash read-only memory; and (6) The basic input output system starts an operating system of the host device through the boot sector.
