Abstract
A Basic Input/Output System (BIOS) device is designed to control access to a portion of BIOS code loaded in its internal memory. For example, during a boot process, an internal state machine permits access to the portion of the BIOS code in response to authentication of a portable token in communication with the BIOS device. Otherwise, the BIOS device precludes access to the portion of the BIOS code until the portable token is authenticated.
