Note: The operating temperature of the board may be determined by measuring the air temperature from the junction of
the heatsink fins and fan, next to the attachment screw, in a closed chassis, while the system is in operation.
Note: Before attempting to operate this board, the overall temperature of the board must be above the minimum
operating temperature specified. It is recommended that the board temperature be at least room temperature
before attempting to power on the board. The operating and non-operating environment must avoid condensing
humidity.
4 Overview of BIOS Features
4.1 Introduction
The board uses an ASUS AMI BIOS core that is stored in the Serial Peripheral Interface Flash
Memory (SPI Flash) and can be updated through multiple methods (see Section 4.2). 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 32 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 system boots.
4.2 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 ASUS NUCs are available on Download
Center.
