9 Using Setup Utility (BIOS) and HP PC
Hardware Diagnostics (UEFI)
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.

NOTE: Use extreme care when making changes in Setup Utility (BIOS). Errors can prevent the
computer from operating properly.
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
To determine whether available BIOS updates contain later BIOS versions than those currently
installed on the computer, you need to know the version of the system BIOS currently installed.
BIOS version information (also known as
ROM date and System BIOS) can be revealed by pressing
fn + esc (if you are already in Windows) or by using Setup Utility (BIOS).
1. Start Setup Utility (BIOS) (see Starting Setup Utility (BIOS) on page 69 ).
