Using Setup Utility (BIOS) in Windows 8.1

Setup Utility, 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). Setup Utility (BIOS)
includes settings for the types of devices installed, the startup sequence of the computer, and the amount of
system and extended memory.

Starting Setup Utility (BIOS)

CAUTION:
Use extreme care when making changes in Setup Utility (BIOS). Errors can prevent the computer
from operating properly.
Turn on or restart the computer, quickly press esc, and then press f10.

Updating the BIOS

Updated versions of the BIOS may be available on the HP website.
Most BIOS updates on the HP website are packaged in compressed files called SoftPaqs.
Some download packages contain a file named Readme.txt, which contains information regarding installing
and troubleshooting the file.

Determining the BIOS version

the computer, you need to know the version of the system BIOS that is installed.
BIOS version information (also known as ROM date and System BIOS) can be revealed from the Start screen by
typing support, selecting the HP Support Assistant app, selecting My computer, and then selecting
System Information, or by using Setup Utility (BIOS).
