6 Overview of BIOS Features
6.1 Introduction
The board uses an Intel AMI BIOS core that is stored in the Serial Peripheral Interface
Flash Memory (SPI Flash) and can be updated through multiple methods (see Section
6.2). The SPI Flash contains the BIOS Setup program, POST, the PCI auto-configuration
utility, LAN EEPROM information, and Plug and Play support. The SPI Flash includes a
256 MB flash memory device.
The BIOS Setup program can be used to view and change the identification information
and the BIOS settings for the system. The BIOS Setup program is accessed by pressing
<F2> after the POST memory test beings and before the operating ssystem boots.
6.2 BIOS Updates
The BIOS can be updated using one of the following methods:
1. Express BIOS (Windows-based) Update
2. F7 Update
3. Power Button Menu Update
4. UEFI Shell Update
More information and instructions on how to use each of these methods can be found
at BIOS Update and Recovery Instructions
. All BIOS update files for Intel NUCs are
available on Download Center.
6.2.1 BIOS Recovery
It is unlikely that anything will interrupt a BIOS update; however, if an interruption
occurs the BIOS could be unstable. Table 20 lists the drives and media types that can
be used for BIOS recovery. The BIOS recovery media does not need to be made
bootable. More information about BIOS recovery methods and instructions can be
found at BIOS Update and Recovery Instructions
.
