HX401 BIOS Manual

BIOS Version 1.51

1- Getting Started

1.1 - Introduction

The UEFI BIOS is a small program which runs when your computer starts and configures its basic functions. That configuration is automatic, and most users will be satisfied with the default configuration. If the default configuration is not sufficient, the BIOS has setup menus which can be used to reconfigure the computer.

The purpose of this manual is to document the function of the BIOS and its available configuration options. The text of this document lists the BIOS menus and options exactly as they appear in the BIOS menus: in the correct order, with the correct default values for this BIOS version. Some options are hidden based on how other options are set and which hardware is detected in the system, so some options may not appear on all systems. Informative screenshots are also provided throughout, but their contents may not exactly match this BIOS version.

To access the BIOS setup menu, hold the Delete key on the keyboard while turning on the system. After a few seconds, the BIOS front page menu is shown:

On each menu, the selected option is shown in white, other options are shown in blue, and read-only options are shown in gray. Some menus have multiple screens, which are shown at the top of the screen. The active screen is shown with a gray background and inactive screens are shown with blue backgrounds.

BIOS menus are navigated by pressing keys on the keyboard:

F1 shows help on available keyboard shortcuts
↑/↓ arrow keys select the option above or below the currently-selected option
→/← arrow keys activate the screen to the right or left of the currently-activated screen
Enter activates the selected option. If that option is a menu, it is opened. If it is a configuration option, a dialog is opened to select a new value.
F5/F6 change the selected option to its previous or next value
Esc returns to the previous menu
F9 restores all options to their factory default values
F10 saves all options and restarts the system

1.3 - The Front Page

Several options are available on the front page:

Continue: continues the boot process normally, booting the installed operating system
Boot Manager: opens a menu to select which device should be booted
Device Management: opens a menu which shows the status of the system hardware
Boot From File: opens a menu to select a UEFI executable to boot
Administer Secure Boot: opens a menu which manages the Secure Boot configuration of the system
Setup Utility: opens the BIOS setup utility
MEBx: opens the Intel AMT configuration utility

1.4 - Boot Manager

The boot manager menu shows the devices available to be booted. The installed operating system and any attached USB drives will be listed. If enabled in the setup utility, the UEFI shell is also listed. Selecting an option boots it.

1.5 - Setup Utility

The setup utility shows the status of the system and allows many configuration options to be changed. These options affect the functionality, stability and security of the system, and should not be changed without an understanding of their meaning.

The setup utility has many screens. Press the →/← arrow keys to select between them.

1.6 - Commonly-used Configuration Options

Several configuration options are frequently used.

Advanced > PCH-IO Configuration > State After G3

Default value: S0 State; possible values: S0 State, S5 State

Controls the state the system enters after G3 (power loss). If set to S5, the system remains off when initially connected to power. If set to S0, the system boots when connected to power.

Advanced > PCH-IO Configuration > Wake on LAN Enable

Default value: Enabled; possible values: Enabled, Disabled

Enables or disables Wake-on-LAN functionality on the onboard network interfaces.
