Intel D865GLC Socket 478 Micro-ATX Motherboard

The Intel D865GLC is a Micro-ATX motherboard built around the Intel 865G chipset, designed for Socket 478 Pentium 4 and Celeron processors. It supports front-side bus speeds up to 800 MHz for Pentium 4 chips, and its four DDR DIMM slots accommodate up to 4GB of memory. For a board of its era, the D865GLC is well-equipped with onboard essentials: the Intel Extreme Graphics 2 controller handles basic display duties, the Analog Devices AD1985 codec provides integrated audio, and a built-in Ethernet LAN controller covers networking.

Expansion options include three PCI slots and one AGP slot, allowing users to add a dedicated graphics card or other peripherals as needed. With six USB ports and a Micro-ATX footprint that fits into both compact and full-size cases, the D865GLC offers flexibility for legacy system builds. This board is most relevant today for users who need to keep an older Pentium 4 system running — whether for specialized software compatibility, industrial equipment, or hobbyist projects — rather than as a platform for new builds.
