Abstract
A hot pluggable bus in a computer system includes one or more slots for receiving hot pluggable bus adapters and a hot plug controller also coupled to the bus. When a mechanical member associated with a slot is actuated by the user, a signal is sent to the hot plug controller to indicate that the user is about to remove the bus adapter. At that time, the hot plug controller programs a control register to enable a system error signal to thereafter permit the hot plug controller to assert the system error signal when it detects a master abort pertaining to an attempted transaction to the slot which is vacated by the user removing the bus adapter from the slot.
