Quick Start
To begin operating your KP915GV motherboard, perform the
following:
• Read and save all instructions.
• Ensure that the jumper settings match your requirements.
• Attach all necessary peripheral devices to the appropriate
headers and connections on the board using the information
provided on the following pages.
• Power on the system.
• Run the BIOS setup utility (press <Delete> during POST) if you
need to change any settings to match your requirements.
Caution - There is a risk of explosion if
the battery is replaced with an incorrect type.
Dispose of used batteries according to the
manufacturer's instructions.
To avoid damage or injury, always
exercise the following precautions when
handling this product:
• Use a grounding wrist strap or other
static dissipating device.
• Power off the system.
• Disconnect all power cables
Power Supply Requirements
This board uses a 20-pin ATX power connector. In order to avoid damaging any devices, make sure that
they have been installed properly prior to connecting the power supply. It is recommended that the board
be used with a power supply that supports a minimum current load of 0.3A or less on the 5V supply
rail and 2A or less on the 3.3V supply rail (see note below).
 Support for ATX12V power supplies
 Supports hard- and soft-switched power supplies with jumper-less configuration
Note: This board with CPU and memory may draw as little as 400mA of 5V and 2A of 3.3V during
start-up (actual loads depend on installed devices). The power supply under consideration must be
verified as compatible with the projected total system start-up loads for these supply rails. If the
power supply minimum current level requirements are not at or below the level of current loads that
are actually drawn, unpredictable start-up operation may result, such as the power supply latching
off. If this occurs, the AC input to the power supply must be removed and re-attached or the power
supply switch cycled off and on, in order to turn the system back on.
Processor Support
The board supports both Intel®Celeron™ D 340/341 (2.93GHz 533MHz FSB 256K L2) and Pentium® 4
550/551 (3.4GHz 533/800MHz FSB 1MB L2) processors. Both the processor voltage and operating
frequency are automatically adjusted by the motherboard to suit the installed processor. A complete list of
tested processors is available from the RadiSys web page http://www.radisys.com.

System Memory
Four 240-pin DIMM sockets are provided that support DDR2 400/533 MHz, non-ECC, unbuffered memory
modules in 256MB, 512MB, 1GB, and 2GB sizes, which may be installed as single DIMMs if desired. The
two memory channels are interleaved: Addresses are ping-ponged between the channels after each cache
line (64-B boundary). For dual interleaved mode, DIMMs must be installed in matched pairs, installed in
sockets with identical color (e.g. locations DIMM1 and DIMM3, then DIMM2 and DIMM4). If a total of 4GB of
DIMMs is installed, the maximum available memory will be approximately 3.24GB, with the balance of the
address space being consumed by other resources in the system. A complete list of tested memory is
available from the RadiSys web page http://www.radisys.com.
Memory Installation:
This motherboard includes four 240-pin slots with 1.8V for DDR2. You must install at least one memory bank to ensure
normal operation.
Installation of DDR2 Memory
1. There is only one gap in the middle of the DIMM slot, and the memory module can be fixed in
one direction only. Unlock a DIMM slot by pressing the module clips outward.
2. Align the memory module to the DIMM slot, and insert the module vertically into the DIMM slot.
DDR2 Memory bank
128 Pins 112 Pins
3. The plastic clips at both sides of the DIMM slot will lock automatically.
CAUTION
Be sure to unplug the AC power supply before adding or removing expansion cards or other
system peripherals, especially the memory devices, otherwise the motherboard or the system
memory might be seriously damaged.

1. Graphics resolution up to 2048 x 1536 pixels with 32-bit color support at 75Hz
2. 15-pin D-sub connector
Network
A single Ethernet port is available, either 10/100 or 10/100/1000Mbit depending on the product version,
supporting remote boot, PXE and Wake-On-LAN capabilities. Connection to the network is achieved through
an RJ45 connector that has integral LED’s to provide link status information. If needed, a second
10/100/1000Mbit Ethernet port can be provided (with a second RJ45 connector).
Configuration
The majority of the configuration of the board is done through the setup utility built into the BIOS – discussed
later in this document. There are, however, a number of jumpers that control the operation of the board as
described below. Some jumpers are not fitted to certain products.
See the product manual for a depiction of the jumper positions and locations on the board.
Operation Mode Jumper (JP3)
This jumper selects one of the following operating modes for the motherboard (pins 1, 3, 5) and controls
write capability for the CPLD content (pins 2, 4, 6).
Normal Mode (Jumper between pins 1 & 3) This is the factory default position the jumper should be in for
normal operation of the motherboard.
Configure Mode (Jumper between pins 3 & 5) With the jumper in this position the motherboard automatically
runs the BIOS Setup utility regardless of the state of the Setup disable flag that can be set in
the BIOS defaults. In this mode, the CMOS RAM contents are ignored and the defaults are
used to configure the motherboard.
Recover Mode (No jumper) With no jumper installed on pins 1, 3, and 5 recovery mode is entered. The
motherboard does not boot and waits until a valid recovery diskette is detected and then
copies new BIOS into the ROM. The motherboard must be powered down and then re-
powered with the jumper in the normal position before normal operation can resume.
CPLD Write Enabled (Jumper between pins 2 & 4) In this position the contents of the CPLD can be
reprogrammed.
CPLD Write Protected (Jumper between pins 4 & 6) This is the factory default position. In this position, or
with no jumper on pins 2, 4, and 6, the contents of the CPLD are protected from
reprogramming.
BIOS Boot Block Write Protect Jumper (JP2)
(Jumper between pins 1 & 2) This is the factory default position. A jumper installed in this position. or no
jumper installed, enables changes to contents of BIOS ROM boot block (unlocked position). Some
motherboard applications may want to have boot block write-protected BIOS. This can be provided via the
BIOS boot block write protection jumper facility. If a jumper is installed between pins 2 & 3 (locked position),
the contents of BIOS ROM boot block cannot be changed in any way.
Clear CMOS Jumper (JP1)
(Jumper between pins 2 & 3) This is the factory default position. Either this position or no jumper installed, is
the normal operating configuration. Installing a jumper between pins 1 & 2 clears (resets) the CMOS.

BIOS
The BIOS is based on Phoenix Award BIOS. Configuration of the board is achieved, in the majority of cases,
through BIOS settings. These can be viewed and modified using the BIOS set-up utility, which is provided to
perform system configuration changes and to display current settings and environment information. The
BIOS setup utility stores configuration settings in system non-volatile storage. Changes affected by BIOS
setup will not take effect until the system is rebooted.
Setup Utility
During the boot, pressing the 'DEL' key on the keyboard requests the BIOS Setup utility be launched once
the self-test is complete and before searching for a boot device. The Setup utility is provided to perform
system configuration changes and to display current settings and environment information. The Setup utility
stores configuration settings in system non-volatile storage. Changes affected by BIOS Setup will not take
effect until the system is rebooted. See the Product Manual for detailed information on settings and options.
Configuration Reset
Activating the Clear CMOS jumper produces a "reset system configuration" request and the BIOS loads the
default system configuration values during the next POST.
After power-up or reset, the BIOS perform a self-test (POST) that attempts to determine if further operation is
possible and that the detected configuration is expected. This process can complete normally or result in a
warning or an error. The boot process does not stop after a warning but displays a message on the primary
display device. If an error is detected, the boot process is halted. If possible, a message is displayed but
failures early on in the test can only be indicated by POST codes.
Once the initial part of the self-test process is completed, the display device is initialized and boot messages
can then be sent to the display. By default, the display is in Quietboot mode in which the customizable logo is
visible on screen. If the Quietboot mode is disabled (BIOS Setup) then sign-on and test progress messages
are visible. Pressing the 'TAB' key on the keyboard during a Quietboot switches the display to text mode -
providing the progress messages.
The BIOS will then search for boot devices in the order configured by the BIOS Setup and load an operating
system from the first boot device found. Control is then passed to the operating system and the motherboard
BIOS plays no further part in the boot except to provide run-time services.
POST Logo Change (OEM)
See the Product Manual for information needed to change the logo screen in the BIOS bin file.
CMOS Default Change
See the Product Manual for information needed to customize default CMOS (BIOS setup) settings.
