ABSTRACT:
The disclosed embodiments relate generally to providing increased data integrity in computer systems and, more particularly, to using a system management processor to maintain the integrity of stored information. A system management processor detects an attempt to reboot the computer system and holds the system processor or processors in a reset state. While the system processor or processors are held in the reset state, the system management processor checks data such as the system BIOS to identify corruption. If the data checked by the system management processor is not corrupted, the system processor or processors are removed from the reset state and allowed to continue normal operation. If the data checked by the system management processor is corrupted, the system management processor repairs the corrupted data before removing the system processor or processors from the reset state.
