RAR file of 532 KB with documentation for an Intel 440BX design, the chipset used on many Pentium II and Pentium III motherboards. The name gives no revision or content type, but a reference schematic is most likely. Retro-PC repairers use such diagrams to follow the 100 MHz front-side bus, SDRAM and AGP connections, locate the clock generator and voltage regulators, and understand common failure points. Since vendors modified the reference design, treat component designators as a guide rather than an exact match.
