Problems solved by technology

When PFR fails to verify the BIOS active, it only adopts a complete coverage strategy, which lacks pertinence and causes the undamaged parts to be cleared and restored. The recovery time is too long, which causes a waste of resources and a waste of time.

Abstract

The invention provides a BIOS firmware recovery method and system based on PFR, a terminal and a storage medium, and the method comprises the steps: dividing a business region stored by a BIOS into a plurality of sub-regions, and storing different firmware files in the plurality of sub-regions respectively; performing firmware file integrity verification on the plurality of sub-regions based on a platform firmware recovery function; and if an abnormal sub-region in which the stored firmware file is damaged exists in the verification result, reading a backup firmware file of the abnormal sub-region from a backup region stored in the BIOS, and writing the backup firmware file into the abnormal sub-region. Existing configuration can be stored to the maximum extent, previous configuration information loss is avoided, and file recovery time is shortened.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a PFR-based BIOS firmware recovery method, system, terminal and storage medium. Background technique [0002] Platform firmware recovery function PFR is a new security technology designed by Intel. The purpose of PFR is to protect platform assets, detect malicious or wrong behaviors such as damaged firmware, and restore platform firmware to a good state. [0003] In the security framework of PFR, BIOS FLASH is divided into three parts, divided into active, recovery, and staging. The uncompressed, directly executed firmware is stored in active, the compressed backup file is stored in recovery, and the staging is a temporary buffer for upgrading. When the device is started, PFR will verify the active, and the device will start from the active after the verification is passed. When the verification fails, PFR will restore the image in recovery to active, and then restart. When th...
