Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating system's USB
drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and
to install an operating system that supports USB. However, this requires the addition of USB 3.1
drivers to the operating system image prior to beginning installation. By default, Legacy USB
support is set to Enabled.
Legacy USB support operates as follows:
1. When you apply power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and
configure the BIOS Setup program.
4. POST completes.
5. The operating system loads. While the operating system is loading, USB keyboards and mice
are recognized and may be used to configure the operating system. (Keyboards and mice are
not recognized during this period if Legacy USB support was set to Disabled in the BIOS
Setup program.)
6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are
recognized by the operating system, and Legacy USB support from the BIOS is no longer
used. This requires the operating system to have USB 3.1 driver support in order to recognize
devices attached to any of the Intel NUC's external USB ports.
To install an operating system that supports USB, verify that Legacy USB support in the BIOS
Setup program is set to Enabled and follow the operating system's installation instructions.

BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel
World Wide Web site:
 Intel® Firmware Update Utility for Windows with a single .exe, which enables automated
updating while in the Windows environment. Using this utility, the BIOS can be updated from
a file on a hard disk, a USB drive (a flash drive or a USB hard drive), or from the file location on
the Web.
 Intel® Firmware Update Utility, which support working on Windows, EFI shell and Linux
operating systems. Using this utility, the BIOS can be updated from a file on a hard disk, or a
USB drive (a flash drive or a USB hard drive).
 Intel F7 switch during POST allows a user to select where the BIOS .CAP file is located and
perform the update from that location/device. Similar to performing a BIOS Recovery without
removing the BIOS configuration jumper.
All utilities verify that the updated BIOS matches the target system to prevent accidentally
installing an incompatible BIOS.
NOTE
Review the instructions distributed with the upgrade utility before attempting a BIOS update.
