4.5 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 2 on page 20 shows the location of the battery.

5.1 Connectors and Headers
CAUTION
Only the following connectors and headers have overcurrent protection: back panel USB
Type A and Type C, front panel USB, internal USB headers, internal power header, and
DC Vin jack.
All other 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.

5.3 Thermal Considerations
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 5.4.
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.

6 Overview of BIOS Features
6.1 Introduction
The board uses an Intel AMI BIOS core that is stored in the Serial Peripheral Interface
Flash Memory (SPI Flash) and can be updated through multiple methods (see Section
6.2). The SPI Flash contains the BIOS Setup program, POST, the PCI auto-configuration
utility, LAN EEPROM information, and Plug and Play support. The SPI Flash includes a
256 MB flash memory device.
The BIOS Setup program can be used to view and change the identification information
and the BIOS settings for the system. The BIOS Setup program is accessed by pressing
<F2> after the POST memory test beings and before the operating ssystem boots.
6.2 BIOS Updates
The BIOS can be updated using one of the following methods:
1. Express BIOS (Windows-based) Update
2. F7 Update
3. Power Button Menu Update
4. UEFI Shell Update
More information and instructions on how to use each of these methods can be found
at BIOS Update and Recovery Instructions
available on Download Center.

It is unlikely that anything will interrupt a BIOS update; however, if an interruption
occurs the BIOS could be unstable. Table 20 lists the drives and media types that can
be used for BIOS recovery. The BIOS recovery media does not need to be made
bootable. More information about BIOS recovery methods and instructions can be
found at BIOS Update and Recovery Instructions

6.3 Boot Options
In the BIOS Setup program, the user can choose to boot from a hard drive, removeable
driver, or the network. The default setting is for the hard drive to be the first boot
device, the removeable drive second, and the network third.
NOTE 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.
6.3.1 Boot Device Selection During Post
Pressing the <F10> key during POST causes a boot device menu to be displayed. The
menu displays the list of available boot devices.
6.3.2 Power Button Menu
As an alternative to Configuration Mode or normal POST hotkeys, the user can use the
power button to access a menu with BIOS and boot options. The Power Button Menu is
accessible via the following sequence:
1. System is in S4/S5 (not G3)
2. User pushes the power button and holds it down for 3 seconds
3. The Front Panel Power Button LED will be on for the first 3 seconds. After 3
seconds, the LED will begin to blink in the following pattern: 0.25 seconds off, 0.25
seconds on, 0.25 seconds off 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:
If an unrecognized key is hit, then the BIOS will do nothing 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.

6.4 Hard Disk Drive Password Security Feature
The Hard Disk Drive Password Security feature blocks ready and write access to the
hard disk drive until the correct password is given. Hard disk drive passwords are set in
BIOS Setup and are prompted for BIOS POST. For convenient support for resuming
from S3, 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 32 characters in
length.
The User hard disk drive password, when set, will be required on each power cycle until
the Master Key or User hard disk drive password is submitted.
The Master Key hard disk drive password, when set, will not lock the drive. The Master
Key hard disk drive password exists as an unlock override if the User hard disk drive
password is forgotten. Only the User hard disk drive password, when set, will cause a
hard disk to be locked on a system power cycle. Table 22 show the effects of setting
the hard disk drive passwords.

Master and User Set User
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 the 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

SATA connector).
6.5 BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program and
who can boot the computer. A Supervisor and User password can be set for the BIOS
Setup program and for botting 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 Supervisor Mode.
• The User password gives restricted access to view and change Setup options in
the BIOS Setup program. This is 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 or User password to access Setup. Users have access to Setup
regardless to which password is used.
• Setting the User password restricts who can boot the computer. The password
prompt will be displayed before the computer boots. 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, 0-9, and special characters. Passwords
may be up to 20 characters in length.
• To clear a set password, enter a blank password after entering the existing
password.
Table 23 shows the effects of setting the Supervisor password and User password. This
table is for reference only and is not displayed on the screen.
