Intel DB440FX Motherboard 669523-605 Pentium II Slot 1 440FX Chipset 233-300MHz

The Intel DB440FX is an ATX-form-factor system board built around the Intel 440FX (Natoma) chipset, designed to accept Intel Pentium II processors via the Slot 1 (SEC cartridge) interface at speeds from 233 to 300 MHz. This board carries Intel part number AA 669523-605 and represents Intel's own first-party desktop board design from the mid-to-late 1990s, when the Pentium II and Slot 1 interface defined mainstream desktop computing performance.

Applications

The Intel DB440FX was designed for mid-1990s desktop workstations and professional computing environments built around the Pentium II platform. The 440FX chipset (codenamed Natoma) was Intel's first chipset to support the Pentium II's new Slot 1 architecture, bridging the transition away from the older Socket 7 interface used by the original Pentium and competing AMD/Cyrix CPUs. This generation of board targeted business desktops, entry-level workstations, and enthusiast builds during roughly 1997–1998, when the Pentium II at 233–300 MHz represented mainstream to upper-mid-range performance. Today these boards are sought by vintage computing collectors, retro-PC builders, and anyone maintaining legacy Pentium II systems for industrial control or specialized period-accurate setups. The integrated Ethernet, VGA, and USB ports on this board made it a relatively feature-rich option for its era, reducing the need for add-in cards in compact builds.
