Intel Hub Architecture

Intel Hub Architecture (IHA) was Intel's architecture for the 8xx family of chipsets, starting c. 1999 with the Intel 810. It uses a memory controller hub (MCH) that is connected to an I/O Controller Hub (ICH) via a 266 MB/s bus. The MCH chip supports memory and AGP, while the ICH chip provides connectivity for PCI, USB, sound, IDE hard disks and LAN.
