Abstract
Apparatus and method is disclosed for providing hot-add and hot swap capability to a computer system with a processor, and a memory, connected to a system bus. The apparatus includes a first bus, an adapter card slot, a switchable interface unit and hot-swap hot-add program code means. The first bus is connected to the system bus. The adapter card slot has a first port and a second port. The switchable interface unit includes a primary port and a secondary port. The primary port is connected to the first bus and the secondary port is connected to the first port of the adapter card slot. The switchable interface unit is responsive to a hot-swap hot-add power-down request to disconnect the second port from the first bus. The switchable interface unit is also responsive to a power-up request to reconnect the second port to the first bus. The hot-swap hot-add program code means in the memory accepts a request to connect a peripheral device adapter card into the second port of said adapter card slot, and responsive to the request communicates a power-down request to the switchable interface unit.
