NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with SO-DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the SO-DIMMs may not function under the determined frequency.
NOTE
Intel NUC Boards NUC8i3BEB, NUC8i5BEB and NUC8i7BEB support only 4 Gb and 8 Gb memory technologies (also referred to as “SDRAM density”). Table 4 lists the supported SO-DIMM configurations. Table 5

1.9 Real-Time Clock Subsystem

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied via the power supply 5 V STBY rail.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be notified during the POST.
When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 1 on page 3 shows the location of the battery.

1.13.1.1 System States and Power States
Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state.
Table 11 lists the power states supported by the board along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.

NOTE
The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events.

1.13.2 Hardware Support

The boards provide several power management hardware features, including:
Wake from Power Button signal
Instantly Available PC technology
LAN wake capabilities
Wake from USB (not after G3)
WAKE# signal wake-up support
Wake from S5
Wake from CIR
+5 V Standby Power Indicator LED
NOTE
The use of Wake from USB from an ACPI state requires an operating system that provides full ACPI support.

1.13.2.1 Power Input
When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu.
1.13.2.2 Instantly Available PC Technology
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is only supplying Standby power, and the front panel LED will be amber or secondary color if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 12 on page 23 lists the devices and events that can wake the computer from the S3 state.
The use of Instantly Available PC technology requires operating system support and drivers for any installed M.2 add-in card.
1.13.2.3 LAN Wake Capabilities
LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer.
1.13.2.4 Wake from USB
USB bus activity wakes the computer from an ACPI S3 state (not after G3).
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.13.2.5 WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S3 or S4 state.
1.13.2.6 Wake from S5
When the RTC Date and Time is set in the BIOS, the computer will automatically wake from an ACPI S5 state.
1.13.2.7 Wake from Consumer IR
CIR activity wakes the computer from an ACPI S3, S4, or S5 state.
1.13.2.8 +5 V Standby Power Indicator LED
The standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 8 shows the location of the standby power LED.

1.13.3 Microsoft Modern Standby Support

Intel NUC Products NUC8i3BE/NUC8i5BE/NUC8i7BE support Windows* 10 Modern Standby, Microsoft’s implementation of ACPI low power S0 idle. This allows the system to reduce power consumption and only wake when necessary, as for system maintenance tasks or user intervention. Modern Standby is required for Wake-on-Voice capability.
NOTES
You cannot switch between ACPI S3 and Modern Standby. Standby power model switching is only supported with a complete operating system reinstallation. Switching from one standby power model to another will prevent the proper functioning of sleep states.
Updating BIOS or resetting BIOS to defaults will preserve the current standby power model.

2 Technical Reference

2.1 Memory Resources

2.1.1 Addressable Memory

The board utilizes a maximum of 32 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (SPI Flash device), and chipset overhead resides above the top of DRAM (total system memory). On a system that has 32 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions. These functions include the following:
BIOS/SPI Flash device (64 Mb)
Local APIC (19 MB)
Direct Media Interface (40 MB)
PCI Express configuration space (256 MB)
PCH base address registers PCI Express ports (up to 256 MB)
Memory-mapped I/O that is dynamically allocated for M.2 add-in cards (256 MB)
Integrated graphics shared memory (up to 512 MB; 64 MB by default)
The board provides the capability to reclaim the physical memory overlapped by the memory mapped I/O logical address space. The board remaps physical memory from the top of usable DRAM boundary to the 4 GB boundary to an equivalent sized logical address range located just above the 4 GB boundary. All installed system memory can be used when there is no overlap of system addresses.

2.2 Connectors and Headers

CAUTION
Only the following connectors and headers have overcurrent protection: back panel and front panel USB.
The other internal connectors and headers are not overcurrent protected and should connect only to devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these connectors or headers to power devices external to the computer’s chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves.
Furthermore, improper connection of USB header single wire connectors may eventually overload the overcurrent protection and cause damage to the board.

CAUTION
Intel NUC Kit Features
A chassis with a maximum temperature of 50 oC at the processor fan inlet is recommended. If the internal ambient temperature exceeds 50 components do not exceed their maximum case temperature.
o
C, further thermal testing is required to ensure
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board.
All responsibility for determining the adequacy of any thermal or system design remains solely with the system integrator. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance.
CAUTION
Ensure that the ambient temperature does not exceed the board’s maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section 2.8.
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in shorter than expected product lifetime.

Table 29 provides maximum case temperatures for the components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the board.
Table 29. Thermal Considerations for Components
specification updates
To ensure functionality and reliability, the component is specified for proper operation when Case Temperature is maintained at or below the maximum temperature listed in Table 30. This is a requirement for sustained power dissipation equal to Thermal Design Power (TDP is specified as the maximum sustainable power to be dissipated by the components). When the component is dissipating less than TDP, the case temperature should be below the Maximum Case Temperature. The surface temperature at the geometric center of the component corresponds to Case Temperature.
It is important to note that the temperature measurement in the system BIOS is a value reported by embedded thermal sensors in the components and does not directly correspond to the Maximum Case Temperature. The upper operating limit when monitoring this thermal sensor is Tcontrol.

3 Overview of BIOS Features

3.1 Introduction

The board uses 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, POST, the PCI auto-configuration utility, embedded controller (EC) firmware, 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 production BIOSes are identified as BECFL357.86A.
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.

3.2 BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64 Mb flash memory device.

3.3 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.

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 first 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.

3.5 BIOS Updates

The BIOS can be updated using one of the following methods:
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 or a USB drive (a flash drive or a USB hard drive).
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 or a USB drive (a flash drive or a USB hard drive).
Pressing <F7> key 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.
Intel® Visual BIOS has an option to update the BIOS from a valid .bio file located on a hard
disk or USB drive. Enter Intel Visual BIOS by pressing <F2> during POST.
Using Front Panel power button menu option
The update BIOS will be verified that it 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.

3.6 BIOS Recovery

It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged. Table 32 lists the drives and media types that can and cannot be used for BIOS recovery. The BIOS recovery media does not need to be made bootable.

3.7 Boot Options

In the BIOS Setup program, the user 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.
NOTE
Optical drives are not supported by the onboard SATA connectors. Optical drives are supported only via the USB interfaces. If the optical drive is not bootable, it will be ignored during the POST process.

3.7.1 Network Boot

The network can be selected as a boot device. This selection allows booting from the onboard LAN.
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.”
NOTE
When no bootable disk or USB device is found, the system will default to network boot.

3.7.2 Booting Without Attached Devices (Headless)

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 monitor
Keyboard
Mouse

3.7.3 Changing the Default Boot Device during POST

Pressing the <F10> key during POST causes a boot device menu to be displayed. This menu displays the list of available boot devices. Table 33 lists the boot device menu options.
Table 33. Boot Device Menu Options
Boot Device Menu Function Keys Description
<Esc> Exits the menu and boots according to the boot priority defined
through BIOS setup

3.7.4 Power Button Menu

As an alternative to normal POST Hotkeys, the user 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 (soft off); will not work if system is in G3 (after “no power” state)
2. User pushes the power button and holds it down for 3 seconds
3. The front panel power button LED will change from Blue to Amber then the user can release
the power button.
4. User releases the power button before the 4-second shutdown override can occur.
If this path is taken, the BIOS will use default settings, ignoring settings in VPD where possible.
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
[F10] Enter Boot Menu
[F12] Network Boot
[F3] Disable Fast Boot is only displayed if at least one Fast Boot optimization is enabled.
If an unrecognized key is hit, then the BIOS will 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 system.

3.8 Hard Disk Drive Password Security Feature

The Hard Disk Drive Password Security feature blocks read and write accesses to the hard disk drive until the correct password is given. Hard Disk Drive Passwords are set in BIOS SETUP and are prompted for during BIOS POST. For convenient support of S3 resume, the system BIOS will automatically unlock drives on resume from S3. Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 19 characters in length.
The User hard disk drive password, when installed, will be required upon each power-cycle until the Master Key or User hard disk drive password is submitted.
The Master Key hard disk drive password, when installed, will not lock the drive. The Master Key hard disk drive password exists as an unlock override in the event that the User hard disk drive password is forgotten. Only the installation of the User hard disk drive password will cause a hard disk to be locked upon a system power-cycle.
Table 34 shows the effects of setting the Hard Disk Drive Passwords.
Table 34. Master Key and User Hard Drive Password Functions
During every POST, if a User hard disk drive password is set, POST execution will pause with the following prompt to force the user to enter the Master Key or User hard disk drive password:
Enter Hard Disk Drive Password:
Upon successful entry of the Master Key or User hard disk drive password, the system will continue with normal POST.
If the hard disk drive password is not correctly entered, the system will go back to the above prompt. The user will have three attempts to correctly enter the hard disk drive password. After the third unsuccessful hard disk drive password attempt, the system will halt with the message:
Hard Disk Drive Password Entry Error
A manual power cycle will be required to resume system operation.
NOTE
As implemented on Intel NUC Board NUC8i3BEB, Intel NUC Board NUC8i5BEB and Intel NUC Board NUC8i7BEB, Hard Disk Drive Password Security is only supported on either SATA port 0 (M.2 ) or SATA Port 1 (onboard SATA connector). The passwords are stored on the hard disk drive so if the drive is relocated to another computer that does not support Hard Disk Drive Password Security feature, the drive will not be accessible.
Currently, there is no industry standard for implementing Hard Disk Drive Password Security on AHCI or NVME drives. Hard drive encryption can still be implemented and does not require Hard Disk Drive Password Security.

3.9 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 or 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 both passwords are set, the user can enter either 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 20 characters in
length.
To clear a set password, enter a blank password after entering the existing password.
Table 35 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen.
