 Desktop Board Features

USB 2.0 Support

The Desktop Board supports up to eight USB 2.0 ports (four ports routed to the back
panel and four ports routed to two front panel USB 2.0 headers). The USB 2.0 ports
are compatible with USB 1.1 devices. USB 1.1 devices will function normally at
USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support
USB 2.0 transfer rates. Disabling High-Speed USB in the BIOS reverts all USB 2.0
ports to USB 1.1 operation. This may be required to accommodate operating systems
that do not support USB 2.0.

NOTE
Computer systems that have an unshielded cable attached to a USB port might not
meet FCC Class B requirements, even if no device or a low-speed USB device is
attached to the cable. Use a shielded cable that meets the requirements for a
full-speed USB device.

SATA Interface
The Desktop Board supports two SATA channels (3.0 Gb/s) that support one device
per channel. The SATA controller supports IDE and ACHI configuration and can
operate in both legacy and native modes.

Expandability
For system expansion, the Desktop Board provides one PCI connector that can support
either a single PCI add-in card or a single- or dual-slot PCI riser card.

BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI
and SATA auto-configuration utilities, and the video BIOS.

PCI Auto Configuration

If you install a PCI add-in card in your computer, the PCI auto-configuration utility in
the BIOS automatically detects and configures the resources (IRQs, DMA channels,
and I/O space) for that add-in card. You do not need to run the BIOS Setup program
after you install a PCI add-in card.

 Intel Desktop Board D425KT Product Guide

Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the supervisor or user
password was entered.
• Setting a user password restricts who can boot the computer. The password
prompt is 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, you can enter either password to boot the computer.
For instructions on resetting the password, see Clearing Passwords on page 36.

Power Management Features

Power management is implemented at several levels, including:
• Software support through the Advanced Configuration and Power Interface (ACPI)
• Hardware support:
― Power connector
― Fan header
― +5 V standby power indicator LED
― LAN Wake capabilities
― Instantly Available PC technology
― Wake from USB
― Wake from PS/2 devices
― PME# wakeup support
― Wake from serial port

ACPI
ACPI gives the operating system direct control over the power management and Plug
and Play functions of a computer. The use of ACPI with the Desktop Board requires an
operating system that provides full ACPI support.

Hardware Support
Fan Header
The Desktop Board has a 3-pin chassis fan header. See Figure 10 on page 33 for the
location of the chassis fan header.

+5 V Standby Power Indicator

CAUTION
If the AC power has been switched off and the standby power indicator is still lit,
disconnect the power cord before installing or removing any devices connected to the
board. Failure to do so could damage the board and any attached devices.

The Desktop Board’s standby power indicator, shown in Figure 4, is lit when there is
standby power to the system. This includes the DIMM sockets and the PCI bus
connector, even though the computer appears to be off.

Figure 4. Location of the Standby Power Indicator

 Intel Desktop Board D425KT Product Guide

Instantly Available PC Technology

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-
RAM) sleep-state. While in the ACPI S3 sleep-state, the computer will appear to be off
(the hard drive(s) and fan will power off, the front panel power LED will blink). When
signaled by a wake-up device or event, the system quickly returns to its last known
state.
The board supports the PCI Bus Power Management Interface Specification. Add-in
boards that also support this specification can participate in power management and
can be used to wake the computer.
The use of Instantly Available PC technology requires operating system support and
PCI 2.3 compliant add-in cards and drivers.

LAN Wake Capabilities

The board’s LAN wake capabilities enable remote wake-up of the computer through a
network. The LAN subsystem network adapter monitors network traffic at the Media
Independent Interface. The board supports LAN wake capabilities with ACPI in the
following ways:
• By Ping
• By Magic Packet
Upon detecting the configured wake packet type, the LAN subsystem asserts a wake-
up signal that powers up the computer.

Wake from USB

USB bus activity wakes the computer from an ACPI S1 or S3 state.

NOTE
Wake from USB requires the use of a USB peripheral that supports wake from USB.

Wake from PS/2 Device

PS/2 keyboard activity wakes the computer from an ACPI S1, S3, S4, or S5 state.
However, when the computer is in an ACPI S4 or S5 state, the only PS/2 activity that
will wake the computer is the Alt + Print Screen key combination or the Power key
available only on some keyboards.

PME# Wakeup Support

When the PME# signal is asserted on the PCI bus, the computer wakes from an ACPI
S1, S3, S4, or S5 state.

Wake from Serial Port

Serial port activity wakes the computer from an ACPI S1 or S3 state.

Installing and Removing Memory

NOTE
To be fully compliant with all applicable Intel SDRAM memory specifications, the
boards require DIMMs that support the Serial Presence Detect (SPD) data structure.

The Desktop Board has two 204-pin DDR3 SO-DIMM sockets that support up to 4 GB
of system memory. To install system memory on the Desktop Board, see Figure 7 and
follow these steps:
1. Observe the precautions in "Before You Begin" on page 23.
2. Install the first DIMM (Figure 7, A) in the bottom (DIMM 0) socket. Align the notch
in the DIMM with the key in the socket (Figure 7, B), while holding the DIMM with
the back edge tilted slightly upwards, insert it in the socket, and gently push the
back edge down until it snaps into the retention arms (Figure 7, C).
3. If you are installing a second DIMM, repeat Step 2 using the top (DIMM 1) socket
(Figure 7, D).

Figure 7. Installing System Memory

To remove an SO-DIMM from a socket, gently spread the socket’s retention arms
(Figure 7, C) to disengage them from the SO-DIMM.

 3 Updating the BIOS
The BIOS Setup program can be used to view and change the BIOS settings for the
computer. You can access the BIOS Setup program by pressing the <F2> key after
the Power-On Self-Test (POST) memory test begins and before the operating system
boot begins.
This chapter tells you how to update the BIOS by either using the Intel Express BIOS
Update utility or the Iflash Memory Update utility, and how to recover the BIOS if an
update fails.

Updating the BIOS with the Intel® Express

BIOS Update Utility
With the Intel Express BIOS Update utility you can update the system BIOS while in
the Windows environment. The BIOS file is included in an automated update utility
that combines the functionality of the Intel® Flash Memory Update Utility and the ease
of use of Windows-based installation wizards.
To update the BIOS with the Intel Express BIOS Update utility:
1. Go to http://www.intel.com/p/en_US/support?iid=hdr+support.
2. Navigate to the Intel Desktop Board D425KT page, click “[view] Latest BIOS
updates,” and select the Express BIOS Update utility file.
3. Download the file to your hard drive. (You can also save this file to a removable
USB device. This is useful if you are updating the BIOS for multiple identical
systems.)
4. Close all other applications. This step is required. Your system will be rebooted at
the last Express BIOS Update window.
5. Double-click the executable file from the location on your hard drive where it was
saved. This runs the update program.
6. Follow the instructions provided in the dialog boxes to complete the BIOS update.

Update Utility
You can use the information in this section to update the BIOS using the Iflash
Memory Update Utility.

Obtaining the BIOS Update File

You can update to a new version of the BIOS by using the Iflash BIOS update file.
The Iflash BIOS update file is a compressed file that contains the files you need to
update the BIOS. The Iflash BIOS update file contains:
• New BIOS file
• Intel Flash Memory Update Utility
You can obtain either of these files through your computer supplier or by navigating to
the Intel Desktop Board D425KT page at
http://www.intel.com/p/en_US/support?iid=hdr+support .
Navigate to the Intel Desktop D425KT page, click “[view] Latest BIOS updates,” and
select the Iflash BIOS Update utility file.

CAUTION
Do not interrupt the process or the system may not function properly.

Using the Iflash Memory Update Utility

With the Iflash Memory update utility you can update the system BIOS from a
bootable USB flash drive or other bootable USB media. The Iflash BIOS update files
can be extracted locally to your hard drive and copied to a bootable USB flash drive or
other bootable USB media.

NOTE
Review the instructions distributed with the update utility before attempting a BIOS
update.

CAUTION
Do not interrupt the process or the system may not function properly.

1. Uncompress the BIOS update file and copy the .BIO file and IFLASH.EXE to a
bootable USB flash drive or other bootable USB media.
2. Configure the BIOS or use the F10 key option during POST to boot to the USB
device.
3. Manually run the IFLASH.EXE file from the USB device and manually update the
BIOS.

Recovering the BIOS

It is unlikely that anything will interrupt a BIOS update; however, if an interruption
occurs, the BIOS could be damaged. Table 11 lists the drives and media types that
can and cannot be used for BIOS recovery. The BIOS recovery media does not have
to be bootable.

Table 11. Acceptable Drives/Media Types for BIOS Recovery

Media Type Can be Used for BIOS Recovery?
CD-ROM drive connected to the SATA interface Yes
USB removable drive (a USB Flash Drive, for example) Yes
USB diskette drive (with a 1.44 MB diskette) No
USB hard disk drive No

 A Board Status and Error Messages
This appendix describes status and error messages generated by the Desktop Board’s
BIOS. The BIOS indicates these error messages with front-panel Power LED blink
codes, speaker beep codes, and by displaying text on the video monitor.

BIOS Beep Codes

The BIOS uses audible beep codes to signal status messages and error messages
indicating recoverable errors that occur during the POST. The beep codes are listed in
Table 12. These beep codes can be heard through a speaker attached to the board’s
line out audio jack (see Figure 2, B on page 15).

Table 12. BIOS Beep Codes

Type Pattern Frequency
F2 Setup/F10 Boot One 0.5-second beep when the BIOS is 932 Hz
Menu Prompt ready to accept keyboard input
Video error On-off (1.0 second each) two times, then a 932 Hz
2.5-second pause (off); the entire pattern When no VGA option ROM
repeats (beeps and pause) once and the is found.
BIOS will continue to boot.
Memory error On-off (1.0 second each) three times, then 932 Hz
a 2.5-second pause (off); the entire pattern
repeats (beeps and pause) until the system
is powered off.
Thermal trip warning Alternate high and low beeps (1.0 second High beep 2000 Hz
each) for eight beeps, followed by system Low beep 1500 Hz

is powered off.
Thermal trip warning Each beep will be accompanied by the
following blink pattern: 0.25 second on,
0.25 second off, 0.25 second on,
0.25 second off. This results in a total of
16 blinks followed by system shut down.

POST Error Messages

The BIOS also displays error messages on the video monitor when certain recoverable
errors occur during the POST. Table 14 lists the error messages with a brief
description of each.
