Systems are provided for the enhancement of the system BIOS for microprocessor-based devices (34). Before the end of the BIOS start-up procedure, the BIOS operation is diverted to a BIOS authentication system (10) which may be a portion of an enhanced system BIOS (14). The BIOS security authentication system (10) establishes communication with an information module (26), if the information module (26) is present. The information module (26) is typically a removable or installable card, which may be unique to one or more users. Based upon an information exchange between the security authentication module (10) and the information module (26), the security module (10) allows or prevents the system BIOS start-up procedure to resume and finish.
