| An
integrated circuit ( generally Intel or VIA ) on the motherboard
that is responsible for the hard disk drive
controller, I/O controller and integrated hardware such as sound card or
video card if present on the motherboard. The Southbridge gets its
name for commonly being South of the PCI
bus.
Below is a graphic illustration of the ASUS
P5AD2-E motherboard and some basic explanations of each of the major
portions of the motherboard including the southbridge. As shown in
the below picture, it's common for the northbridge and southbridge to
have a heatsink; in addition, the
northbridge is usually slightly larger than the southbridge.
Some newer motherboards have
replaced the northbridge and the southbridge with IHA.
