5 Computer Setup (BIOS) and
Advanced System Diagnostics
Windows 8
Using Computer Setup
Computer Setup, or Basic Input/Output System (BIOS), controls communication between all the input
and output devices on the system (such as disk drives, display, keyboard, mouse, and printer).
Computer Setup includes settings for the types of devices installed, the startup sequence of the
computer, and the amount of system and extended memory.
NOTE: Use extreme care when making changes in Computer Setup. Errors can prevent the computer
from operating properly.

NOTE: An external keyboard or mouse connected to a USB port can be used with Computer
Setup only if USB legacy support is enabled.
To start Computer Setup, follow these steps:
1. Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu”
message is displayed at the bottom of the screen.
2. Press f10 to enter Computer Setup.
