What is used to change motherboard settings?

To change motherboard settings, users typically enter the BiOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware during the computer's boot-up process. This is usually done by pressing a specific key, such as F2, Del, or Esc, right after powering on the system. Within the BiOS/UEFI interface, users can adjust various settings related to hardware configuration, boot order, and system performance.
