Introduction
The Intel® Intel 4 Series Chipset family is designed for use in desktop platforms. The chipset contains two components: GMCH (or MCH) for the host bridge and I/O Controller Hub 10 (ICH10) for the I/O subsystem (G45, G43, P45, P43 Express Chipset only). The ICH10 is the tenth generation I/O Controller Hub and provides a multitude of I/O related functions. The Intel G41 Chipset uses the I/O Controller Hub 7 (ICH7). Figure 1, Figure 2, and Figure 3 show example system block diagrams for the Intel® 4 Series Chipset.
