Intel ICH2

The Intel ICH2 (I/O Controller Hub 2) is a southbridge chip used in Intel chipsets from the early 2000s. It handles I/O functions such as USB, storage, and PCI interfaces. The ICH2 supports up to 4 USB 2.0 ports, offering improved data transfer speeds over USB 1.1. It is typically paired with Intel's northbridge chips like the 815 or 820 series to form a complete chipset for Pentium III and early Pentium 4 systems.
