Abstract:
A computer system comprising:a first section of non-volatile memory configured to store a BIOS program, the first section of non-volatile memory being reprogrammable; a second section of non-volatile memory operatively coupled to the first section of non-volatile memory, the second section of non-volatile memory being configured to store a boot-block program; and non-volatile random access memory (NVRAM) operatively coupled to at least one of the first section of non-volatile memory and the second section of non-volatile memory; the boot-block program having a validation routine configured to validate the NVRAM and to validate the BIOS program stored in the first section of non-volatile memory, and the boot-block program using an encrypted code to validate the NVRAM and to validate the BIOS program.
