A legacy port is a port or connector on a PC that is considered fully or partially obsolete. Some manufacturers, particularly in laptops, remove the legacy ports in lieu of "modern" ports such as USB ports. The modern ports usually provide much of the functionality of the older ports; special USB adapters are often used to replicate the connectors for older devices. Modern motherboards utilize separate Super I/O controllers to provide legacy ports since current chipsets do not offer direct support for them.
