Configure BIOS/UEFI Flashcards
Lesson 3B
PC or system firmware provides low-level code to allow PC components installed on a particular motherboard to be initialized so that they can load the main operating system software.
BIOS/UEFI
firmware only supports 32-bit operation and limited
functionality. Systems Setup can be accessed during PC booting by pressing Esc, Del, F1, F2, F10, or F12.
Basic Input/Output System (BIOS)
Firmware provides support for 64-bit CPU operation at boot, a full GUI and mouse operation at boot, networking functionality at boot, and better boot security and legacy boot.
Unified Extensible Firmware Interface (UEFI)
defines the order in which the system firmware searches devices for a boot manager

Trusted platform module (TPM)
A secure USB key or thumb drive used to store cryptographic material can be referred to as a
hardware security module (HSM).
