Memory Configurations
The processor supports the following types of memory configurations:
• Dual Channel (Interleaved) mode. This mode offers the highest throughput for real world applications. Dual
channel mode is enabled when the installed memory capacities of both SO-DIMM channels are equal. Technology
and device width can vary from one channel to the other but the installed memory capacity for each channel must be
equal. If different speed SO-DIMMs are used between channel, the slowest memory timing will be used.
• Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world
applications. This mode is used when only a single SO-DIMM is installed or the memory capacities are unequal.
Technology and device width can vary from one channel to the other. If different speed SO-DIMMs are used
between channels, the slowest memory timing will be used.

• DirectX Video Acceleration (DXVA) support for accelerating video processing
• Full AVC/VC1/MPEG2 HW Decode
• Intel® HD Graphics with Advanced Hardware video Transcoding (Intel® Quick Sync Video)
Video Memory Allocation
Intel® Dynamic Memory Technology (DVMT) is a method for dynamically allocating system memory for use as graphics
memory to balance 2D/3D graphics and system performance. If your computer is configured to use DVMT, graphics
memory is allocated based on system requirements and application demands (up to the configured maximum amount).
When memory is no longer needed by an application, the dynamically allocated portion of memory is returned ot the
operating system for other uses.

Restarting Your Xi3 NUC
You can restart your Xi3 NUC by briefly depressing the Power Button on the top of the computer.

The board uses an Intel® Visual BIOS that is stored in the serial Peripheral Interface Flash Memory (SPI Flash) and can be updated using
a disk-based program. The SPI Flash contains the Visual BIOS Setup program, PST, the PCI auto-configuration utility, LAN EEPROM
information, and Plug and Play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs
are identified as WYLPT10H.86A.
When the BIOS setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares
the CPU version and the microcode version in the BIOS and reports if the two match.
The Visual BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup
program is accessed by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins and before the
operating system boot begins. {Note, the maintenance menu is displayed only when the board is in configure mode.}
The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64Mb (8192 Kb) flash memory device.
System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network.
The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about
the computing system and its components. Using SMBIOS, a system administrator can obtain the system types,
capabilities, operational status, and installation dates for system components. The MIF database defines the data and
provides the method for accessing this information. The BIOS enables applications such as third-party management
software to use SMBIOS. The BIOS stores and reports the following SMBIOS information:
• BIOS data, such as the BIOS revision level
• Fixed-system data, such as peripherals, serial numbers, and asset tags
• Resource data, such as memory size, cache size, and processor speed
• Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS information. The BIOS
supports an SMBIOS table interface for such operating 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.
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 accessed 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.
BIOS Updates
The BIOS can be updated using either of the following utilities, which are available on the Intel® World Wide Web site:
Chapter 3 – BIOS Settings

• Intel® Express BIOS Update utility, 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 a
CD-ROM, or from the file location on the Web.
• Intel® Flash Memory Update Utility, which requires booting from DOS. 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 a CD-ROM.
• Intel® F7 switch during POST allows a user to select where the BIOS .bio file is located and perform the update
from that location/device. Similar to performing a BIOS Recovery without removing the BIOS configuration jumper.
Both utilities verify that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS.
BIOS Recovery
It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged.
Table 27 lists the drives and media types that can and cannot be used for BIOS recovery. The BOS recovery media does
not need to be made bootable.
Acceptable Drives / Media Types for BIOS Recovery
Media Type
Can be used for BIOS recovery?
Hard disk drive (connected to SATA or USB)
Yes
CD/DVD drive (connected to SATA or USB)
Yes
USB flash drive
Yes
USB diskette drive (with a 1.4 MB diskette)
No (BIOS update file is bigger than 1.4MB size limit)
Note: Support file systems for BIOS recovery: NTFS (sparse, compressed, or encrypted files are not supported), FAT32, FAT16, FAT12,
ISO 9660
Boot Options
In the BIOS Setup program, you can choose to boot from a hard drive, optical drive, removable drive, or the network. The
default setting is for the optical drive to be the first boot device, the hard drive second, removable drive third, and the
network fourth.
The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card
with a remote boot ROM installed.
Pressing the <F12> key during POST automatically forces booting from the LAN. To use this key during POST, the User
Access Level in the BIOS Setup program’s Security menu must be set to Full.
For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system
loader is invoked even if the following devices are not present:
• Video adapter
• Keyboard
• Mouse
Pressing the <F10> Key during POST causes a boot device menu to be displayed. This menu displays the list of available
boot devices.
Boot Device Menu Options
Boot Device Menu Function Keys
Description
<↑> or <↓>
Selects a default boot device
<Enter>
Exits the menu, and boots from the selected device
<Esc>
Exits the menu and boots according to the boot priority
defined through BIOS setup
Power Button Menu
As an alternative to Back-to-BIOS Mode or normal POST Hotkeys, you can use the power button to access a menu. The
Power Button Menu is accessible via the following sequence:
1. System is in S4/S5 (Not G3)
2. User pushed the power button and holds it down
3. The system will emit three short beeps from the PC speaker, then stop to signal the user to release the power button
4. User releases the power button before the 4-second shutdown override
If this boot path is taken, the BIOS will use default settings, ignoring settings in VPD where possible.

At the point where Setup Entry/Boot would be in the normal boot path, the BIOS will display the following prompt and wait for
a keystroke:
[ESC] Normal Boot
[F2] Intel® visual BIOS
[F3] Disable Fast Boot
[F4] BIOS Recovery
[F7] Update BIOS
[F9] Remote Assistance
[F10] Enter Boot Menu
[F12] Network Boot
[F2] Enter Setup is displayed instead if Visual BIOS is not supported.
[F3] Disable Fast Boot is only displayed if at least one Fast Boot optimization is enabled.
[F9] Remote Assistance is only displayed if Remote Assistance is supported
If an unrecognized key is hit, then the BIOS will beep and wait for another keystroke. If one of the listed hotkeys is hit, the
BIOS will follow the indicated boot path. Password requirements must still be honored.
If Disable Fast Boot is selected, the BIOS will disable all Fast Boot optimizations and reset the systems.
BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A
supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup
program. This is the supervisor mode.
• The user password gives restricted access to view and change Setup options in the BIOS Setup program. This is
the user mode.
• If only the supervisor password is set, pressing the <Enter> key at the password prompt of the BIOS Setup program
allows the user restricted access to Setup.
• If both the supervisor and user passwords are set, users can enter either the supervisor password of the user
password to access Setup. Users have access to Setup respective to which password is entered.
• Setting the user password restricts who can boot the computer. The password prompt will be displayed before the
computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If
other passwords are set, the user can enter wither password to boot the computer.
• For enhanced security, use different passwords for the supervisor and user passwords.
• Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 16 characters in length.
• To clear a set password, enter a blank password after entering the existing password.
