BIOS/UEFI Firmware

Category: infrastructure

The low-level firmware that initializes hardware and boots the operating system.

UEFI is the modern successor to BIOS. It is the interface where you configure system clocks, boot orders, and hardware voltages. It serves as the "master controller" that bridges the gap between raw hardware and the operating system software.

Common Examples

• You must access the UEFI setup menu to enable XMP profiles, which allow your high-speed RAM to run at its rated factory frequency.
• Always download the latest BIOS firmware directly from the motherboard manufacturer to ensure compatibility with newer processor generations.
