End of Interactive Support
Intel is announcing the end of interactive support for the Intel® DK440LX Motherboard. See the End of Interactive Support Announcement for details.
Latest BIOS and Drivers
The current BIOS for the Intel® DK440LX Motherboard and the latest driver versions for the Intel DK440LX Motherboard on-board audio, SCSI and LAN also can be found here.
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:
- During Post press F2 to enter CMOS Setup.
- After Setup loads, go to the advanced screen.
- Go to the Resource Configuration submenu.
- Select the memory range C800 to CBFF and press Enter.
- Select "Reserved" and press Enter.
- 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.
