Identifying Your Intel NUC BIOS Version and Model on Linux

Discovering the BIOS version and model of your Intel NUC on a Linux system might seem daunting, but it’s actually a straightforward process. Many users often need this information for various reasons, such as troubleshooting, updating drivers, or ensuring compatibility with specific operating systems. The ability to quickly identify your NUC’s BIOS details allows for efficient system management and maintenance. This guide will equip you with the necessary knowledge and commands to effortlessly retrieve this crucial information directly from your Linux terminal, empowering you to better understand and optimize your Intel NUC.

Methods for Identifying Your Intel NUC BIOS

There are several ways to determine the BIOS version and model of your Intel NUC using Linux. We’ll explore two common and reliable methods: using the `dmidecode` command and inspecting the `/sys` filesystem.

Using `dmidecode`

The `dmidecode` utility is a powerful tool that extracts information about your system’s hardware from the SMBIOS/DMI table. This table contains details about the BIOS, motherboard, chassis, and other components.

To use `dmidecode`, open your terminal and execute the following command:

sudo dmidecode | less

This command requires `sudo` privileges because it accesses system-level information. The `| less` part pipes the output to the `less` program, allowing you to scroll through the results easily. Look for sections labeled “BIOS Information” and “System Information”. The BIOS version will be listed under “BIOS Information”, and the model (often referred to as “Product Name”) will be found under “System Information”.

To filter the output and directly find the BIOS version, use the following command:

sudo dmidecode -t bios | grep Version:

Similarly, to find the model:

sudo dmidecode -t system | grep “Product Name:”

Inspecting the `/sys` Filesystem

The `/sys` filesystem provides a structured view of the kernel’s internal data structures, including hardware information. While less direct than `dmidecode`, it can sometimes offer an alternative method.

Navigate to the following directory:

cd /sys/devices/virtual/dmi/id

Within this directory, you’ll find several files containing system information. The `product_name` file typically holds the model of your NUC. You can view its contents using the `cat` command:

cat product_name

The BIOS version might not be directly available in this directory. However, you can sometimes find it in the `bios_version` file, although this is less common.

Troubleshooting

• `dmidecode` not found: If you encounter an error indicating that `dmidecode` is not found, you’ll need to install it. Use your distribution’s package manager. For example, on Debian/Ubuntu, use: `sudo apt-get install dmidecode`. On Fedora/CentOS/RHEL, use: `sudo yum install dmidecode` or `sudo dnf install dmidecode`.
• No Output: If `dmidecode` returns no relevant output, it might indicate a problem with the SMBIOS/DMI table. Ensure your BIOS is properly configured and updated.
