Problems solved by technology

Due to the update of the BIOS version, the size of the code area often changes, and the agreed address range and check value need to be changed frequently. Therefore, the generality of the detection program is not good, and it needs to adapt to the change of the BIOS version frequently. Moreover, this detection algorithm cannot cover the configuration data. exception in the zone

Abstract

The embodiment of the invention provides a method and equipment for checking a BIOS (basic input output system). The method comprises the steps as follows: reading preset check heuristic information; storing a start address and a first check value of each code region and a start address and a first check value of each data region; comparing the first check value with a second check value of each code region and the first check value with a second check value of each data region; and when the first check value is not equal to the second check value, returning information that the BIOS content is damaged. According to the method, the data regions and the code regions in the BIOS content can be fully detected, the general flexible BIOS detection algorithm can be realized, and the method can automatically adapt to the BIOS specification upgrading and is suitable for both the traditional BIOS and a BIOS with an EFI (Extensible Firmware Interface); and the blank region in the BIOS content can be skipped in the checking process, so that the efficient online BIOS content detection algorithm is realized and the performance consumption is reduced to the hilt.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and equipment for checking the basic input and output system BIOS. Background technique [0002] Before starting, the Basic Input Output System (BIOS) will conduct a self-test on its own content to ensure that it can be started correctly. The mainstream BIOS of current computer systems uses electrically erasable programmable read-only memory EEPROM, flash memory FLASH, etc. as its firmware storage devices. Due to the low reliability of these devices, bit jumps and content corruption may occur, causing the BIOS to fail self-test during startup, and the computer system cannot be started. In the next startup, an efficient online detection method is needed to detect such faults in time for repairing. [0003] In the prior art, when the system is started, the contents of the BIOS firmware are read immediately and a full copy is saved. During online operation, the entire content of...
