Abstract:
1. A method for recovering a Basic Input Output System (BIOS) image in a computer system, comprising the steps of: executing recovery code stored in a nonvolatile memory in response to a recover BIOS command; rewriting a first BIOS image in said nonvolatile memory with a second BIOS image stored in a protected portion of a nonvolatile storage unit in response to said recovery code; and updating said system using said rewritten second BIOS image in said nonvolatile memory, wherein said first BIOS image is rewritten with said second BIOS image if said first BIOS image is determined to be corrupted and wherein said first BIOS image is determined to be corrupted by comparing a signature of said first BIOS image to a signature received in a secure data packet.
