Abstract
A secure Basic Input/Output System (BIOS)-enabled passthrough system includes a computing device having a computing device component, and a BIOS subsystem in the computing device that is coupled to the computing device component. The BIOS subsystem enables primary access to the computing device component to BIOS drivers. The BIOS subsystem may receive a secondary access session start request from a first BIOS driver to start a secondary access session to use secondary access to the computing device component, it retrieves a first BIOS driver identifier for the first BIOS driver based on the secondary access session start request, determines that the first BIOS driver identifier is a secondary-access-authorized BIOS driver identifier and, in response, begins the first secondary access session and may performs secondary access operation(s) on the computing device component in response to receiving secondary access command(s) from the first BIOS driver during the secondary access session.
