8/ BIOS
8.1. Starting the uEFI BIOS
The 3.5"-SBC-WLU is provided with a Kontron-customized, pre-installed and configured version of AMI Aptio® V uEFI
BIOS. AMI BIOS firmware is based on the Unified Extensible Firmware Interface (UEFI) specification and the Intel®
Platform Innovation Framework for EFI. This uEFI BIOS provides a variety of new and enhanced functions specifically
tailored to the hardware features of the 3.5"-SBC-WLU.
The uEFI BIOS comes with a setup program that provides quick and easy access to the individual function settings for
control or modification of the uEFI BIOS configuration. The setup program allows the accessing of various menus that
provide functions or access to sub-menus with more specific functions of their own.
To start the uEFI BIOS setup program, follow the steps below:
1. Power on the board.
2. Wait until the first characters appear on the screen (POST messages or splash screen).
3. Press the <DEL> key.
4. If the uEFI BIOS is password-protected, a request for password will appear. Enter either the User Password or the
Supervisor Password (see Security menu), press <RETURN>, and proceed with step 5.
5. A setup menu will appear.
The 3.5"-SBC-WLU uEFI BIOS setup program uses a hot key-based navigation system. A hot key legend bar is located
on the bottom of the setup screens.
The following table provides information concerning the usage of these hot keys.
