Compatibility
Supported processors

The motherboard only supports Pentium® II processors that run internally at 233, 266, 300, and 333 MHz, and have a 512KB L2 cache supporting ECC or non-ECC operation.

While the Intel® Celeron® processor uses the same P6 microarchitecture as the Pentium II processor, there are some differences. No qualification or compatibility testing has been performed using the Intel Celeron processor and the BIOS does not contain support for this processor. While the Intel Celeron processor may appear to work in a Intel® DK440LX Motherboard, the reliability of operation is not known.

Warning: Processors not specifically listed by type and rated speed may have requirements that are not supported by the motherboard's design. Use of unsupported processors may result in improper operation, damage to the motherboard or processor, or reduced product life.

System memory

Contents

System Memory Combinations
The motherboard has four dual inline memory module (DIMM) sockets. Minimum memory size is 16 MB; maximum memory size is 512 MB. The BIOS automatically detects memory type, size, and speed.

The motherboard supports the following memory features:

  • JEDEC MO-161 compliant 168-pin DIMMs with gold-plated contacts.

  • Unbuffered 66-MHz ECC/non-ECC SDRAM or 60-ns EDO ECC/non-ECC DIMMs

  • 3.3 V memory only

  • Single- or double-sided DIMMs in the sizes listed in the following table.

DIMM Size Configuration
16 MB 2M x 72/64
32 MB 4M x 72/64
64 MB 8M x 72/64
128 MB 16M x 72/64


Memory can be installed in one, two, three or four sockets. Memory type, size, and speed can vary between sockets, so EDO and SDRAM DIMMs can be installed on the same motherboard.

Note: There may be mechanical interference with the DIMM 0 socket (J6G3) and the DIMM 1 (J6G2) socket in some combinations of ATX chassis and peripherals, such as CD-ROMs.

Note: The Intel® DK440LX Motherboard supports DIMMs with both asymmetrically and symmetrically addressable DRAMs.

Problems With Keyboard or Mouse
Several possible causes may lead to keyboard lockups or other problems with a keyboard or mouse attached to a Intel DK440LX Motherboard.


Processors Supported
The Intel DK440LX Motherboard supports Pentium® II processors at 233, 266, 300, or 333 MHz. Also see the additional information on processors supported and special information for using 333 MHz Pentium II processors.



Error: "Allocation error static node 00" when an AGP video card is installed
To resolve this issue, reserve the memory address range C800 to CBFF as follows:
  1. During Post press F2 to enter CMOS Setup.
  2. After Setup loads, go to the advanced screen.
  3. Go to the Resource Configuration submenu.
  4. Select the memory range C800 to CBFF and press Enter.
  5. Select "Reserved" and press Enter.
  6. Press F10 to save and exit.

Motherboard Won't Power Up - Power Supply Requirements
The Intel DK440LX Motherboard is designed to operate with at least a 250 Watt power supply. A higher-wattage supply may be required for heavily-loaded configurations. The power supply must provide +5VSB current (720mA). If the power supply does not supply sufficient current, the Intel DK440LX Motherboard may not power up. Additionally, if the power supply can not supply sufficient current and does not have overload protection, the power supply may be damaged.


Motherboard Won't Power Up - Sleep/Resume Switch
If the motherboard won't power up or the fan turns on for one second then shuts down, ensure you are using a momentary switch for the sleep/resume feature. The result may be the board getting stuck in sleep mode. Use the correct type of switch and remove the battery for 20 minutes to clear the flip-flop that controls sleep mode.


Help In Dealing With IRQ Shortages
Motherboards like the Intel DK440LX Motherboard set aside IRQs to service devices that have been integrated onto the board. This can sometimes lead to a resource shortage, which can be resolved with one of several techniques.


IRQ9 Cannot Be Re-Assigned
IRQ9 is not available to assign to ISA add-in cards because it is dedicated to the power management function of the PIIX4 controller on the motherboard. This is true for other motherboards which use the 82371AB PIIX4 component.


Installing Windows NT* 4.0 from CD-ROM
A complete explanation of system hangs when installing Windows NT 4.0 from CD-ROM is available in the Intel DK440LX Motherboard Frequently Asked Questions. A workaround is included in this documentation.


Inaccessible Boot Device
An "Inaccessible boot device" error may be encountered after installing Windows NT* 4.0 Service Pack 3 on the Intel DK440LX Motherboard. This occurs after the Service Pack installation overwrites the existing SCSI driver.


Single Processor Configurations
When using only a single microprocessor, the processor must be installed in the boot processor slot (closest to the back panel) and a termination card should be installed in the second (application processor) slot.


Conflict With PCI Bridge and AGP Video Controller
A conflict with a "PCI standard PCI-to-PCI Bridge" and the AGP video controller in the Windows 95 Device Manager does not affect the functionality of AGP with Windows 95. The "PCI standard PCI-to-PCI bridge "is actually the Intel® 82443LX Pentium II Processor to AGP Controller, which Windows 95 cannot properly identify.


Will my ATA-66 Hard Drive Work on the Intel DK440LX Motherboard?
The IDE controller integrated into the Intel DK440LX Motherboard supports Ultra DMA modes 0,1, and 2. Ultra DMA mode 2, also known as ATA-33 or Ultra DAM 33, is the highest speed transfer mode supported by the Intel DK440LX Motherboard. The motherboard hardware cannot support the maximum transfer rate of the ATA-66 drives. A drive that complies with the ATA-66 specification will run timings up to Ultra ATA-33 on the Intel DK440LX Motherboard. Please refer to the Technical Product Specification and the Motherboard Specification Update for more complete details on the various transfer modes.

Frequently Asked Questions: Intel DK440LX Motherboard

What can I do if I am experiencing keyboard lockups on my DK440LX?
If you are experiencing problems with a keyboard or mouse connected to a Intel DK440LX Motherboard, try the following:
  • Try moving the keyboard cable to the bottom connector. If a mouse is not being used, the keyboard MUST be connected to the bottom port of the keyboard/mouse connector.

  • Try switching the keyboard and mouse cable connections; that is, move the keyboard cable to the mouse connector (top port), and the mouse cable to the keyboard connector (bottom port). With a different brand/model of keyboard and/or mouse, the keyboard and mouse connections can exhibit different loading behavior.

  • Try using a keyboard and mouse with cables of 6' or less. Extended cables on the keyboard or mouse may cause failures in some situations.

  • Try a different brand/model of keyboard and/or mouse. Some models of keyboards and mice exhibit unpredictable behavior.
If the above suggestions do not resolve your issue, you should contact your place of purchase for further assistance.


What processors are supported on the Intel DK440LX Motherboard?
The motherboard only supports Pentium® II processors that run internally at 233, 266, 300, and 333 MHz, and have a 512KB L2 cache supporting ECC or non-ECC operation.

While the Intel® Celeron® processor uses the same P6 microarchitecture as the Pentium II processor, there are some differences. No qualification or compatibility testing has been performed using the Intel Celeron processor and the BIOS does not contain support for this processor. While the Intel Celeron processor may appear to work in a Intel DK440LX Motherboard, the reliability of operation is not known.

Warning: Processors not specifically listed by type and rated speed may have requirements that are not supported by the motherboard's design. Use of these processors may result in improper operation, damage to the motherboard or processor, or reduced product life.

Does the Intel DK440LX Motherboard support the 333 MHz Pentium® II processor?
The Intel DK440LX Motherboard with BIOS version 4D4KL0X0.86A.0017.P08, and future revisions, supports the 333 MHz Pentium II processor. Processor speed is set using the system configuration jumper (J7E1) to access maintenance mode.

Function Jumper J7E1 Configuration Mode
Normal pins 1-2 use current configuration
Configure pins 2-3 access maintenance mode after POST (set processor speed)
Recover none use to recover BIOS from floppy


Note: Conformity with FCC open chassis emission standards was verified with processor speeds up to 300 MHz, the highest processor speed available at the time the motherboard was introduced. Higher speed processors may increase system electromagnetic emissions. It is the responsibility of the system integrator to verify that a system based on this motherboard and any new higher speed processor, including the newly announced 333 MHz PentiumII processor, complies with EMC emission standards.


How do I install and secure a Pentium II processor on the Intel DK440LX Motherboard?
The processor(s) connect to the motherboard through the 242-contact slot connector (formerly referred to as Slot 1 connector). The Intel DK440LX Motherboard uses a dual Retention Mechanism (RM) for securing the Pentium II processor(s) into the 242-contact slot connector. The same dual Retention mechanism is used for either a single or dual processor configuration. When only a single processor is used, a termination card with latching mechanism should be installed in the second (application processor) 242-contact slot connector.

Note: For more information about the dual Retention Mechanism (RM), refer to Pentium II processor Support Components on Intel's web site.


Which processor slot should be used in a uniprocessor configuration?
In a uniprocessor configuration, the processor must be installed in the boot processor slot (the slot closest to the back panel). If the processor is installed in the application processor slot, the computer will not boot. In uniprocessor configurations, a termination card with latching mechanism should be installed in the second (application processor) 242-contact slot connector.


What are the important Pentium II processors considerations for a dual processor configuration?
The DK440LX motherboard supports configurations with one or two Pentium II processors. The processor's VID pins automatically program the single voltage regulator on the motherboard to the required processor voltage. Due to a single voltage regulator motherboard design, dual processor operation requires both processors have the same voltage IDs, otherwise the system won't boot. To insure stable operation in multiprocessing O/S environments, Pentium II processor speed, L2 cache size, L2 cache type (ECC or non-ECC), and processor family ID must match.



What types of memory modules can I install on the Intel DK440LX Motherboard?
The Intel DK440LX Motherboard supports both SDRAM and EDO DRAM DIMMs. The BIOS will automatically detect the memory type, size, and speed. The following memory features are supported:
  • JEDEC MO-161 compliant 168-pin DIMMs with gold-plated contacts

  • Unbuffered 66-Mhz SDRAM or 60-ns EDO ECC DIMMs

  • 3.3V memory only

  • Single or double-sided DIMMs


Note: SDRAM SPD (Serial Presence Data) information must be programmed by the memory manufacturer in accordance with the JEDEC MO-161 specification before the memory components will function on the Intel DK440LX Motherboard.




What memory configurations are supported on the Intel DK440LX Motherboard?
The Intel DK440LX Motherboard has four dual in-line memory module (DIMM) sockets which support both SDRAM and EDO DRAM DIMMs. Memory can be installed in one, two, three or four of the DIMM sockets. Minimum memory size is 16MB. Maximum memory size is 512MB. Memory type, size and speed can vary between sockets. This means EDO and SDRAM DIMMs can be installed on the same motherboard.



I am getting beep code 1-3-3-1 and my motherboard does not boot or show any video. What does this mean?
This beep code indicates that there was a problem during DRAM memory device detection. Check to ensure system memory is properly installed. This error may also occur if the the Serial Presence Detect (SPD) EEPROM data on SDRAM DIMMs is either missing or is not programmed correctly.



How should the jumpers be set on my Intel DK440LX Motherboard?
Unlike some previous Intel motherboards, the Intel DK440LX Motherboard supports a single header (J7E1) which selects the configuration mode for the BIOS Setup program. This allows all motherboard configuration to be handled in software via the Setup program. There are three functions which can be selected by this jumper:

Function Jumper J7E1 Configuration
Normal   The BIOS uses current configuration information and passwords for booting.
Configure   After the POST runs, Setup runs automatically. The maintenance menu is displayed.
Recovery None The BIOS attempts to recover the BIOS from a floppy disk. A recovery diskette is required.


Note: There are no special jumpers for configuring the processor speed or bus frequency. The mechanism for configuring the processor speed is to use the Setup program in Configure mode.

Caution: The jumper settings should never be changed while the system is powered on. Always turn off the computer before changing the jumper.



What are the differences between the Fan Headers on the Intel DK440LX Motherboard?
There are five fan headers on the Intel DK440LX Motherboard. Two of the fan headers are intended for CPU active heat sink support while the remaining three fan headers are intended for chassis fan support. The following figure and table identify the silk screen label, location, function and features of each header.

Fan 4 J2E1 Rear Chassis Mux 0 to SP3 Yes
Fan 5 J12A1 Front Chassis #1 Mux 1 to SP3 Yes


* Mux 3 is connected to GND.

Note 1: Both CPU fans are wired directly to LM79 (no multiplexing). Power Management for the Fan 3 (CPU #1 fan) is disabled on production motherboards beginning with PBA 672282-506. Power Management is disabled on the CPU fan headers to ensure they will NOT to be shut down during a power management event. All chassis fans (rear fan and two front fans) are intended to be power managed.



Why are the chassis fan headers multiplexed into the LM79 hardware monitor and what limitations does this present?
Due to the LM79 design, only three inputs are available to monitor the fan headers. Two of the fan headers are directly wired to SP1 and SP2 of the LM79 inputs. The SP1 and SP2 inputs of the LM79 are reserved for the CPU active heat sink fans. The Intel DK440LX Motherboard provides multiplexing hardware which allows the other three fan headers to be sensed at the SP3 input of the LM79.

Limitations: Implementation of the LM79 hardware monitor on the Intel DK440LX Motherboard has a limitation when using the SP3 input of the LM79. Fan speed sensed at SP3 must have a fan speed greater than 4400 RPM or a low speed error will be reported. This may present problems for customers using applications which monitor fan speed at the chassis headers.

The following figure and table identify the silk screen label, location, function and features of each header.

What processor heat sink solution do I need for the Intel DK440LX Motherboard?
It is recommended that active (fan) heatsinks be used for both the primary and secondary processor to ensure adequate thermal dissipation.

Caution: System cooling requirements vary depending on the particular system configuration, and it is the responsibility of the system designer/integrator to ensure that the Pentium II processor's maximum case temperature (at thermal plate) is not violated.


What additional components do I need to make use of the RAID connector?
The onboard RAIDport connector, in conjunction with an ARO*-1130CA-B Adaptec RAIDport card and the SCSI controller, provides a complete client RAID solution.

For information on obtaining a RAIDport card, visit Adaptec's web page.

What is A.G.P.?
A.G.P. (Accelerated Graphic Port) is a new data bus providing a high-speed channel to main memory. A.G.P bandwidth is 528MB/sec compared to the PCI bus at 252MB/sec. Additionally, A.G.P. supports pipelined instructions and can execute textures and commands directly from main memory. PCI solutions have to down load to local memory. Down load to local memory requires extra time and is limited in size.


What benefits can I expect by using an AGP card on the Intel DK440LX Motherboard?
A.G.P. performance is matched to the Pentium II processor. The back-side L2 cache and Intel's 440LX A.G.P set provide A.G.P., CPU and PCI concurrent operation.

Some Key Benefits of A.G.P. are:
  • Higher performance 1x (66MHz) and 2x (133MHz) bus freq. Vs 33MHz PCI bus
  • Access to the A.G.P. aperture reduces necessary local frame buffer size. This reduces cost while increasing performance by using system memory.
  • Pipelining enables multiple requests a time.
  • Side-Band addressing yields more efficient use of the AD lines reducing system cost.



Why is interrupt IRQ9 not available to assign to my ISA add-in card?
IRQ9 is not available to ISA devices because it is dedicated to the power management function on the PIIX4 controller on the Intel DK440LX Motherboard. This is also true for other motherboards which utilize the PIIX4 controller.


Is there any way to boost the performance of my SCSI sub-system?
Use a PCI slot other than the shared PCI/ISA slot for installing a PCI add-in card that supports bus mastering. The SCSI controller and PCI shared slot share their bus mastering signal. The performance impact of this can be minimized by avoiding installing a Bus Mastering PCI card in the shared PCI slot


How do I disable the onboard SCSI, LAN, Audio or Hardware Monitor?
The onboard SCSI, LAN, Audio or Hardware monitor can be disabled on the Intel DK440LX Motherboard through the BIOS Setup utility.


Why does my system hang when trying to install Windows* NT* version 4.0 from CDROM?
Background: When trying to install Windows NT version 4.0 from the bootable CDROM, a problem is encountered on the DK440LX ATX Motherboard. If the Windows NT version 4.0 CDROM is inserted in the CD drive at boot time, the system will boot from the CDROM. If the CDROM is in the CD drive, the system will boot from the CD even if a floppy diskette is inserted in the FDD (floppy disk drive).

The Windows NT version 4.0 installation routine, executed from the CDROM, automatically detects hardware and installs the associated driver available on the CDROM. If hardware is detected which is not recognized, the installation procedure will request a driver be provided by the operator.

Problem: The Intel DK440LX Motherboard has an Adaptec* AIC-7895 PCI SCSI Host Adapter configured on the motherboard. The Adaptec AIC-7895 is a new component. The Windows NT version 4.0 CDROM was created before the new Adaptec AIC-7895 and it's associated drivers were available. Therefore, the drivers required for the Adaptec AIC-7895 are not on the CDROM.

The installation problem is encountered because the Microsoft installation process interprets the Adaptec AIC-7895 hardware as an older version of Adaptec controller. This incorrect hardware detection leads the installation software to install an older driver without providing an option to the operator for loading the correct driver. The result of installing the incorrect driver is system lockup ("Blue Screen") due to an INACCESSIBLE_BOOT_DEVICE error. At this time we do not know of any solution which can correct the installation process executed from the installation CDROM.

Work Around: There is a procedure which can be used to install Windows NT version 4.0 from the bootable CDROM. This process involves booting the system from a floppy diskette. Once the system is booted from the floppy diskette (CDROM must NOT be inserted in the CD drive at boot time!), the installation procedure can be executed from the Windows NT version 4.0 installation diskette. The installation procedure on the diskette is unaware of the CDROM and will not automatically install the Adaptec drivers. This process allows the operator to load the correct Adaptec AIC-7895 driver prior to completing the installation from the CDROM.


What are the dimensions, and where are the mounting holes located on the Intel DK440LX Motherboard?
The Intel DK440LX Motherboard is designed to fit into an ATX form-factor chassis. The figure below shows the mechanical form factor, the I/O connector locations, and the mounting hole locations. The Intel DK440LX Motherboard is in compliance with all mounting holes specified in the ATX Specification Revision 2.01.

Note: Two additional mounting holes are used on the Intel DK440LX Motherboard which are not found in the ATX Specification Revision 2.01. The integrator should take this added requirement into account when selecting a chassis.

[Intel DK440LX Motherboard Dimensions]



What standard ATX form factor integration issues may exist with the Intel DK440LX Motherboard which were not problems on previous Intel ATX motherboards?
There may be some mechanical interference with the first (J6G3) and second (J6G2) DIMM sockets, in some combinations of ATX chassis, with the peripheral bays (such as hard drives and CD-ROM drives).


How do I connect an external SCSI peripheral to a DK440LX system?
To connect and external SCSI peripheral (such as hard drive) to the Intel DK440LX Motherboard, you will need to use a SCSI termination card which gets installed in an unused I/O slot of the chassis. The SCSI termination card will be provided with the Boxed Intel DK440LX Motherboard. From the termination card, an external SCSI cable can be used to connect external SCSI devices.


How do I configure the SCSI termination on my Intel DK440LX Motherboard?
You can modify the SCSI controller's configuration (including termination) using the integrated SCSISelect Utility. Additionally, the motherboard BIOS Setup utility is also used in configuring SCSI termination.



To enter the BIOS Setup Utility, boot the computer and press <F2> when the Power-On Self Test (POST) begins.

To enter the SCSISelect Utility, boot the computer and press<Ctrl><A> when the following message appears:
Press<Ctrl><A> for SCSISelect(TM) Utility!





    [SCSI Motherboard DK440LX]



    Note: By default, SCSI termination is enabled on the Intel DK440LX Motherboard.


    Why won't my SCSI tape drive work with the DK440LX on-board SCSI controller?
    Intel has discovered an issue with the Intel DK440LX Motherboard where a SCSI tape drive may be identified as a hard drive. When this occurs, the tape drive will not function.

    Work Around: SCSI tape drives tested by Intel can be used without exhibiting this problem if the tape media is NOT present in the tape drive during system power-up. Other tape drives may or may not have similar behavior. Test the drive in question by simply ensuring the tape media is not inserted in the tape drive before booting the system. This is an issue with the on-board SCSI solution and the Intel/Phoenix BIOS used on the Intel DK440LX Motherboard. The issue has been identified with all SCSI tape drives tested by Intel to date. Intel is currently developing a BIOS solution which is expected to be available via this Web Site as soon as evaluation can be completed.

    What special power supply requirements does the Intel DK440LX Motherboard have?
    The Intel DK440LX Motherboard is designed to operate with at least a 250 Watt power supply. A higher-wattage supply may be required for heavily-loaded configurations. The power supply must provide +5VSB current (720mA). If the power supply does not supply sufficient current, the DK440LX motherboard may not power up. Additionally, if the power supply can not supply sufficient current, and does not have overload protection, the power supply may be damaged.


    What is the Auxiliary Power Supply Connector (J1M2) on the Intel DK440LX Motherboard used for?
    The Auxiliary Power Supply Connector (J1M2) on the Intel DK440LX Motherboard is a 1x6 header to allow additional 5V and 3 V current. If a motherboard is heavily loaded with peripherals, the traditional 2x10 ATX power connector may not be able to handle all of the current required (reference to the specifications provided with the power supply being used). The Auxiliary Power Supply Connector (J1M2) should be used for additional load requirements.

    Note: This Auxiliary power connector is different from the Optional Power Connector in the ATX 2.01 specification, which is a 2x3 pin connector used for fan control/monitoring, IEEE-1394 power, and 3.3V sense line.


    What device drivers, used for Intel DK440LX Motherboard operation, are available from Intel?
    The following device drivers will be available when the Intel DK440LX Motherboard is made available to Intel customers.
    • audio drivers
    • SCSI interface drivers
    • LAN drivers (Software also available from: the Intel® EtherExpress LAN adapter site.


    Refer to the driver site for the most current drivers available. Additional drivers may become available at a later date.


    Why doesn't my CD-ROM or second IDE hard drive work with Windows 95?
    The retail version of Windows 95 and OSR2 are unable to completely identify the Intel 82371AB (PIIX4) and Intel 82443LX PCI/A.G.P. Controller (PAC) components on the Intel DK440LX Motherboard. An Intel® Chipset Software Installation Utility is available to update the MSHDC.INF and MACHINE.INF files. After this utility has been run, the enhanced functions of the PIIX4 IDE controller can be accessed.


    Why does the Windows 95 device manager report a conflict with a "PCI standard PCI-to-PCI Bridge " and the AGP video controller?
    The "PCI standard PCI-to-PCI bridge " is really the Intel 82443LX PCI/A.G.P. Controller (PAC) which Windows 95 cannot properly identify. This issue will not affect the functionality of Windows 95, with AGP. An Intel Chipset Software Installation Utility is available to update the MSHDC.INF and MACHINE.INF files.

    Why does the custom "User Logo", displayed at boot time, get erased when the BIOS is updated?  What is the procedure to reprogram the logo is when the BIOS is updated?
    The Phoenix BIOS is designed to always clear the user logo flash area when the BIOS is updated. There are several reasons for this requirement, some of which are related to flash security, manufacturing quality and service return processing.

    Some customers ship configured systems with their own identifying logo (displayed at boot time) installed during system integration in their factory. Once the system has been distributed to the field, it is possible that BIOS updates may be made available from Intel. Updating the system BIOS with only the files distributed by Intel will erase the logo.

    If a customer wants their "User Logo" to be maintained after updating the BIOS (i.e. at the field location), the logo area must be reprogrammed with the custom "User Logo", using the iflash utility. This can be accomplished automatically by executing the iflash utility from an autoexec.bat file on the update boot diskette after the BIOS is updated. The following AUTOEXEC.BAT will automatically update the BIOS followed by programming the "User Logo". The BIOS files and the user logo file must be present on the boot diskette during the update process.

    Note: Only the executable lines are required, user feedback is not mandatory.
