Intel Dakota Dual PII 440LX AGP 3D Sound

Intel DK440LX Motherboard
Workstation Performance for the PC Desktop

The Intel DK440LX motherboard is a high-performance, feature-rich dual-processing solution for the Pentium® II processor-a computing environment that combines the power of the Pentium Pro processor with the capabilities of Intel's MMX™ media-enhancement technology. Now workstation and power users can tap into the turbo-charged performance of two Pentium II processors to run sophisticated graphics, CAD and business software designed for dual-processing environments. And because it's an Intel processor-based platform, users won't have to compromise compatibility with today's Windows*-based software to access the power of a workstation platform.

Feature-rich, cost-effective
workstation platform

The boxed Intel DK440LX motherboard includes many high-performance features already enabled for quick and easy integration. An Adaptec dual channel SCSI delivers higher throughput than IDE. Dual-channel design provides expansion, reliability and cost savings. On-board audio provides a high-quality, cost-effective audio solution. And the integrated Intel EtherExpress™ LAN controller and RJ-45 connector provide immediate network connectivity-without requiring additional hardware integration.

The Intel DK440LX motherboard also offers your workstation and power-user customers a cost-effective alternative to many proprietary RISC-based solutions. And since it's based on the Intel Pentium II processor, your customers are assured of a wide range of compatible peripherals, upgrade solutions, service and support-all easily provided by you, their system integrator.

Advanced workstation capabilities

The Intel DK440LX motherboard supports the Accelerated Graphics Port (AGP), which streamlines the flow of data between the processor, graphics accelerator and system memory, delivering a new level of rich media and graphics performance. For the workstation user, this translates into affordable, high-performance graphics comparable to many proprietary workstations costing thousands of dollars more. Power business users will enjoy smooth performance in 3-D applications from CAD programs to sophisticated data visualization and Web-authoring tools.

In addition, the Intel 440LX AGPset-which makes AGP support possible-provides additional advanced capabilities, including SDRAM support, Ultra ATA and Dynamic Power Management Architecture. Add such innovations as single jumper configuration, advanced BIOS and increased memory support to 512 MB (SDRAM) and it's clear why the Intel DK440LX motherboard is the winning choice for Pentium II processor-based systems.

The quick, easy, tested
integration solution

The boxed Intel DK440LX motherboard provides system integrators with an efficient and tested solution for dual-processing platforms using the Pentium II processor. All required processor integration materials, such as the dual-processor retention mechanism and complete documentation, are included. The Intel DK440LX motherboard is thoroughly evaluated for compatibility with the Pentium II processor in a dual-processing environment, a wide range of peripherals and AGP graphics accelerator cards. What's more, the Intel DK440LX motherboard is backed by a three-year limited warranty-one of the best motherboard warranties in the industry.

Combining a boxed DK440LX motherboard with a boxed Intel Pentium II processor creates a complete integration solution. This alliance of components virtually eliminates the inconvenience and uncertainties often faced when integration materials are purchased and tested separately. Now system integrators can build and sell the latest in PC workstation performance and technology with more than the latest in Intel technology-they can build with confidence.

Improved Productivity,
Lower Cost of Ownership

The DK440LX motherboard also is designed with manageability and reduced cost of ownership in mind. Its on-board hardware management ASIC and LANDesk® Client Manager software work together to provide network administrators and PC support personnel with real-time PC health monitoring, automatic polling and alerting of hardware conditions, and diagnostics that minimize downtime and aid in troubleshooting.

The result: Reduced downtime, faster problem resolution and the ability to anticipate problems before they arise-all of which enhances greater system productivity and lowers total cost of ownership.
