Important Notes

System Memory Combinations

The motherboard has two, dual in-line memory module (DIMM) sockets. Minimum memory size is 16 MB; maximum memory size is 256 MB. The BIOS automatically detects memory type, size, and speed.

The motherboard supports the following memory features:

  • 168-pin DIMMs with gold-plated contacts
  • 66 or 100 MHz SDRAM
  • Non-ECC (64-bit) memory
  • 3.3 V memory only
  • Unbuffered Single- or double-sided DIMMs in the following sizes:
DIMM Size Non-ECC Configuration
16 MB 2M x 64
32 MB 4M x 64
64 MB 8M x 64
128 MB 16M x 64

Synchronous DRAM (SDRAM) can be installed in either or both sockets. EDO DIMMs are not supported. Memory size and speed can vary between sockets.

Note Pentium II processors with 100 MHz front-side bus should be paired only with 100 MHz SDRAM. Processors with 66 MHz front-side bus can be paired with either 66 MHz or 100 MHz SDRAM.

All memory components and DIMMs used with the Intel BL440ZX Motherboard should comply with the PC SDRAM specifications. These include: the PC SDRAM Specification (memory component specific), the PC Unbuffered DIMM Specification, and the PC Serial Presence Detect Specification.

Frequently Asked Questions: Intel® BL440ZX Motherboard

Processor:

  • What processors are supported on the Intel® BL440ZX Motherboard?
    Please see the Processor Support Table for details

  • What processor heat sink solution do I need for the Intel® BL440ZX Motherboard?
    It is recommended that an active (fan) heatsink be used with the processor for proper cooling.
    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 system's maximum case temperature (at thermal plate) is not exceeded. For more details on the thermal considerations, refer to the Intel® BL440ZX Motherboard Technical Product Specification.

  • Why can't I find speed settings in my BIOS configuration mode?
    The processor speed option previously available in configuration mode is not displayed with newer Intel processors, and will not effect the processor speed. Newer Intel processors boot with the ratio preset and tested during manufacturing. The fixed pre-selected ratios are reflected in the EBL_CR_POWERON register.

  • Does the Intel® BL440ZX Motherboard support MMX technology?
    The Intel® BL440ZX Motherboard is designed for Intel Celeron processors in the PPGA package.

    All Intel® Celeron processors contain MMX technology.

Memory:

  • What types of memory modules can I install on the Intel® BL440ZX Motherboard?
    The Intel® BL440ZX Motherboard supports dynamic memory detection for one or two 3.3V, 168-pin (64 bit, 72 bit), 4 clock, 66MHz or 100MHz, unbuffered SDRAM DIMMs.

  • How much main memory is supported on the Intel® BL440ZX Motherboard?
    The Intel® BL440ZX Motherboard has two dual in-line memory module (DIMM) sockets that support SDRAM DIMMs. Memory can be installed in one, two, or both of the DIMM sockets. The minimum DIMM memory size is 16MB and the maximum memory size is 256MB.
    Note BIOS will support non-SPD, 66MHz SDRAM DIMMs. 100MHz DIMMs must use SPD. SDRAM SPD information must be programmed by the memory manufacturer in accordance with the JEDEC MO-161 specification.

  • What memory configurations are supported on the Intel® BL440ZX Motherboard?
    The Intel® BL440ZX Motherboard has two dual in-line memory module (DIMM) sockets that support SDRAM DIMMs. Memory can be installed in one or two of the DIMM sockets. Intel® BL440ZX Motherboard can support memory sizes of 16MB, or 32MB using 16Mbit technology and 32MB, 64MB, or 128MB using 64Mbit technology.

    Memory size and speed can vary between sockets. This means 100-MHz DIMMs and 66-MHz DIMMs can be installed on the same motherboard.

    Note Processors with 66-MHz Front Side Bus (FSB) can be paired with either 66-MHz or 100-MHz SDRAM DIMMs. Processors with 100-MHz FSB should only be paired with 100-MHz SDRAM DIMMS.

  • What kind of problems might occur in an SDRAM-based system that uses non-compliant DIMMs?
    The most extreme example of memory failure causes the system to hang while booting the operating system. This will happen because the system is not able to communicate properly with the memory. In less extreme cases, the memory may generate intermittent errors or fail during stress.

  • I am getting a repeating 6 beep error code 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, and ensure the DIMMs you are using are on the Intel® BL440ZX Motherboard tested memory list.

  • Does Intel qualify memory for use on Intel motherboards?
    No. OEMs and system integrators are solely responsible for qualifying the memory that they include in their systems. Intel will perform only limited testing of a few memory modules to verify functionality of the motherboard's design. Intel does offer a program for 3rd parties to self-test their own memory and to report passing results to Intel for inclusion on our Internet based tested memory list.

  • What is SDRAM memory?
    Synchronous DRAM (SDRAM) improves memory performance through memory access that is synchronous with the memory clock. This simplifies the timing design and increases memory speed because all timing is dependent on the number of memory clock cycles.
    Note To function properly, SDRAM DIMMs used on this motherboard must meet the Intel 4-clock, 66 MHz, unbuffered SDRAM specification (version 1.0) and support CAS Latency 2 for 72-bit SDRAM.

  • Do all SDRAM DIMMs with an SPD EEPROM meet the 4-clock 66 MHz unbuffered SDRAM DIMM Specification?
    No. The SPD device and data structure is only part of the specification. Although the SPD contains data that could be used in configuring the DIMMs into the motherboard, there is no way to determine if this data is valid.

NLX Chassis:

  • Do I need a special chassis for NLX motherboards?
    Yes, the Intel® BL440ZX Motherboard is a NLX Platform and requires a chassis that is compliant with the NLX 1.2 specification . There are no Power supply, I/O slots or data connectors on the Intel® BL440ZX Motherboard. Power, I/O and data connectors reside on an NLX 1.2 compliant riser card. Riser cards may be specific to chassis style or sold by third party vendors. Reference the NLX web site for vendor information.

Power Supply:

  • What special power supply requirements does the Intel® BL440ZX Motherboard have?
    The Intel® BL440ZX Motherboard is designed to operate with at least a 145 Watt power supply for typical system configurations. A higher-wattage supply may be required for heavily-loaded configurations. The power supply must provide +5 Voltage Stand By (+5VSB) with 720mA of current (reference the NLX Power Supply Recommendation V1.1) . If the power supply does not supply sufficient current, some system configurations with the Intel® BL440ZX 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.

  • Why do I need a power supply with 720mA of current on the +5VSB power supply for the Intel® BL440ZX Motherboard?
    The Intel® BL440ZX Motherboard requires a 3.3 volt power supply that complies with the NLX 1.2 specification . In order to utilize Wake on LAN technology capabilities, the Intel® BL440ZX Motherboard also requires a soft on/off power supply. It must provide a +5VSB with 720mA of standby current to keep the remote Wake on LAN circuit alive. Reference the NLX Power Supply Recommendation V1.1*.

  • Why isn't there a power connector on my Intel® BL440ZX Motherboard?
    With the NLX form factor, the power to the motherboard is supplied through the riser card. This allows the easy removal of the "dockable" motherboard from the chassis. In fact, all power and data cables have been moved to the riser. Thus, an NLX 1.2 compliant riser is necessary to power the motherboard.

  • What power supply requirements does the Intel® BL440ZX Motherboard have if a WOL capable Network Interface Card (NIC) is installed?
    A power supply that provides at least 720mA on +5VSB must be used when building a WOL capable system.

    If your power supply is not capable of meeting the 720 mA current requirement, your system may not power up. Also you could experience damage to your power supply if it does not have any over-current protection. Please contact your system integrator to see if your power supply meets the 720 mA current requirement.

    If you are using a WOL capable NIC but are not using the WOL capability you can remove the cable from the NIC to the WOL header on the motherboard. This will prevent the NIC from drawing additional current from the +5VSB.

Connectors/Jumpers:

  • How should the jumpers be set on my Intel® BL440ZX Motherboard?
    There is a single configuration jumper on the motherboard which is used to access configuration mode. All configuration options are then available through the BIOS configuration screen, including selection of CPU speed. (Refer to the Technical Product Specification for more information.)

  • 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 PIIX4E controller on the Intel® BL440ZX Motherboard. This is also true for other motherboards which utilize the PIIX4E controller.

  • Why are there two jumper blocks on the Intel® BL440ZX Motherboard?
    There are two jumper blocks on the Intel® BL440ZX Motherboard. Jumper ( J7B1 ) is for setting the BIOs Setup configuration mode. Jumper ( J8K2 ) is for routing the microphone signal to the riser card. (Refer to the Technical Product Specification for jumper locations and your vendor for riser card information.)

  • Where can I find the motherboard connector information?
    Refer to the Technical Product Specification, Motherboard Connectors, for all motherboard connector information.

  • Where can I find riser card information?
    Refer to the Technical Product Specification, Motherboard Connectors, for all motherboard connector information. Contact your vendor for vendor-specific riser card information.

Video:

  • What is the Accelerated Graphics Port (AGP)?
    AGP is a dedicated graphics bus with higher bandwidth and which allows texturing from main memory which was not possible with the PCI Bus. By providing high-bandwidth access to memory, AGP enables a new level of sophisticated graphics allowing software developers to create richer, more inviting 3D environments with higher resolutions than ever before.

  • What is AGP 2X?
    The PCI bus is a 32bit bus which runs at 33Mhz. Theoretically, the PCI bus can transfer 4 bytes per clock edge at 33MHz or 132MB/sec ideally. Due to bus efficiency overhead, the actual PCI bus transfer rate is somewhat less than the ideal maximum. The AGP bus is a 32bit bus which runs at 66MHz. The AGP bus can transfer 4 bytes per clock edge at 66MHz or 264MB/sec ideally. It easy to see why the APG bus is more than twice as fast as the PCI bus. Because the AGP bus is dedicated to the graphics controller, it is more efficient than the PCI bus making the actual AGP transfer rate is closer to the ideal maximum.

    AGP 2X is an advancement in the graphics controller design which takes advantage of a 440ZX chipset feature which allows AGP data to be clocked on both the rising and the falling edge of the 66MHz AGP bus clock. Thus AGP 2X is double clocking data effectively doubling the AGP data rate, hence AGP 2X or 528MB/sec ideally.

  • What type of AGP video card should be used with the Intel® BL440ZX Motherboard?
    The Intel® BL440ZX Motherboard does not have an addin AGP connector and does not support addin AGP video cards.

Audio:

  • How can the onboard audio be disabled?
    The onboard audio can be disabled using the BIOS Setup Utility. Select the Advanced menu, then the Peripheral Configuration screen. The menu will offer options to enable or disable the audio if it is present on the motherboard.

  • If audio is disabled, does the Intel® BL440ZX Motherboard consume fewer interrupts?
    The Creative Sound Blaster* Audio PCI 64 audio solution uses two sharable interrupts. Enabling or Disabling the audio does not affect resource availability.

  • Is the Creative Sound Blaster* Audio PCI 64 audio solution PC98 Logo compliant?
    Yes, the Creative Sound Blaster Audio PCI 64 audio solution on the Standard Intel® BL440ZX Motherboard platform is compliant to Microsoft PC97, PC98, the AC97 interface and Multimedia PC Level II and III specifications. The Intel® BL440ZX Motherboard reference platform will complete Microsoft PC98 testing with Test suite version 8.0 with all test results validated by Microsoft. Reference to the test results may be verified on the MS Web (URL is www.microsoft.com/hwtest) under Submission Status with Master ID 7680.

  • Is the Creative Sound Blaster Audio PCI 64 audio solution "full duplex"?
    The Creative Sound Blaster Audio PCI 64 audio solution is capable of playing and recording at different sample rates simultaneously. The solution also meets PC97 & PC98 requirements to support videophone operation.

  • Is the Creative Sound Blaster Audio PCI 64 audio solution Sound Blaster and Sound Blaster Pro compatible?
    Yes. Functionally, the Creative Sound Blaster Audio PCI 64 traps on accesses to the Sound Blaster registers and issues appropriate IRQ or SERR commands on the PCI bus. The DMA functionality is handled in a similar fashion.

  • What is AC97 and why is it needed?
    The AC97 (Audio Codec 1997) specification defines a high quality audio architecture which should advance the migration to digital audio while maintaining support for analog interconnects for backward compatibility.

  • Does the Intel® BL440ZX Motherboard support digital audio?
    Yes, the Intel® BL440ZX Motherboard supports digital wave files and midi files.

  • Does this audio solution have a hardware wave table? Wave table add-on? Software wave table driver available in standard driver package?
    The Creative Sound Blaster Audio PCI 64 audio solution provides a 64 voice polyphony software wave table audio solution, therefore a wave table add-on is not required. It is compatible with the Aureal API for 3D Positional Audio. Over 4000 sounds are stored in main memory.

  • What is the advantage of having the audio on the PCI bus over the ISA bus on the Intel® BL440ZX Motherboard?
    ISA DMA memory cycles are replaced with more efficient PCI burst cycles. This allows high bandwidth 3D positional audio with better frame-rates while other PCI bus operations such as LAN, modem or PIIX4E also operate at higher rates. Additionally, the PCI bus requires less system resources and no dedicated resources as does the ISA bus.

  • How many channels or MIDI voices does this solution have?
    The Creative Sound Blaster Audio PCI 64 audio solution provides a 64 voice polyphony wave table audio solution.

  • Are there drivers available for DOS, Windows* 3.11, Windows NT* 3.51, Windows NT 4.0, Windows* 95 and now Windows* 98?

  • Does the Intel® BL440ZX Motherboard have USB legacy support?
    Yes. USB legacy support enables USB keyboards and mice to be used when the operating system drivers are not in place (i.e. at boot time to access BIOS Setup). By default, USB legacy support is disabled. USB Legacy support is only for use in accessing BIOS Setup for the installation of USB aware operating systems.

  • Can I use a second floppy drive on my Intel® BL440ZX Motherboard?
    No, the Intel® BL440ZX Motherboard uses a SMSC FDC37M807 IO component to support the floppy disk controller. This component, and equivalent components, can support a single standard legacy type FDD, a 2.88MB Super I/O type FDD, or a three mode type FDD.


Installation/Configuration:

  • Where can I purchase an NLX compliant riser?
    A current list of suppliers is available on the NLX web Site*, and is updated regularly. Keep in mind that the riser must be able to fit in the selected chassis which in many cases already has a riser built specifically for that chassis. It is the intent of chassis vendors to supply the riser that fits with their chassis and offer several design choices. For vendor-specific information, see the list of manufacturers participating in NLX Development.

  • What type of battery is used in the Intel® BL440ZX Motherboard?
    Standard (3 volt, CR2032) coin cell is used to supply power to the RTC when no power is available from the power supply.

  • How do I disable the onboard features?
    The onboard features can be disabled through the motherboard BIOS Setup utility. .

  • What are the concerns when integrating the Intel® Celeron processor into an NLX chassis?
    Ensure that the chassis and the riser card are compliant with the NLX 1.2 specification . A thorough evaluation needs to be performed by the system integrator on the NLX chassis chosen. This includes mechanical, electrical, thermal, shock, vibration and EMI. The system integrator is responsible for ensuring that there is adequate air flow and cooling requirements for the processor and other components in the system.

  • Can the Intel® BL440ZX Motherboard be used in the same chassis as other Intel motherboards?
    The Intel® BL440ZX Motherboard is a NLX platform and requires a chassis that is compliant with NLX 1.2 specification. To use the Intel® BL440ZX Motherboard in another chassis would require that the chassis meet the NLX 1.2 specification*.

  • Why doesn't my Intel® BL440ZX Motherboard power-up?
    The Intel® BL440ZX Motherboard requires 3.3 volts from the power supply. Additionally, there are some specific requirements for the power sequencing and limits. A momentary switch should be used for the power on/off switch and the sleep/resume switch. The power supply chosen must meet the NLX 1.2 specification .

  • Why are the drivers on Intel 's public web site down revisions of those available on some vendor public web sites?
    Intel performs internal testing on all drivers before they are posted on the Intel developer motherboard web site. In many cases, it is not practical to test all drivers on all motherboards. For this reason, application vendors may release drivers which have not been tested by Intel. These drivers may be available on the vendor public site but not on the Intel public site. This does not mean the drivers do not work but it does indicate the drivers have not been validated by Intel.

  • Why doesn't my CD-ROM or second IDE hard drive work with Windows* 95?
    There are two known issues involving CD-ROM or secondary hard drives:
    • The retail version of Microsoft Windows 95 may not recognize the Intel 82371EB PIIX4E IDE controller used on Intel motherboards, causing the BIOS to disable the secondary IDE channel. This can result in IDE devices (such as CD-ROM drives) not being detected or disappearing after the system is rebooted. A utility is available to update the MSHDC.INF file and resolve the issue.
    • Also, Windows* 95 may fail to recognize a CD-ROM drive that does not comply with the ATAPI specification.

  • 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 82443ZX AGP Controller", which Windows* 95 cannot properly identify. This issue will not affect the functionality of Windows* 95, with AGP.

  • Why isn't my IDE device being displayed during power-up POST?
    All IDE devices must be ATA4 compliant and cable length is limited to 18 inches. IDE devices that are not selected as auto detect in the BIOS setup are not displayed as part of the POST tests.

  • Is the Intel® BL440ZX Motherboard PC98 Logo compliant?
    Yes, the Standard Intel® BL440ZX Motherboard platform is compliant to Microsoft PC97, PC98. The Intel® BL440ZX Motherboard reference platform will complete Microsoft PC98 testing with Test suite version 8.0 with all test results validated by Microsoft.
