Intel NUC Board DN2820FY Technical Product Specification systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. Additional board information can be found in the BIOS under the Additional Information header under the Main BIOS page. 3.4 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. 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 and the maintenance menu. 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. 7. Additional USB legacy feature options can be access by using Intel® Integrator Toolkit. 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. 3.5 BIOS Updates The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: • Intel® Express BIOS Update utility, which enables automated updating while in the Windows environment.
