Abstract
A circuit for enabling replacement of a peripheral device connected to a main system in a computer system includes a selecting section that enables a user to select to replace the peripheral device. The replacement will occur while electrical power is being provided to the main system in a computer system. A display section provides a display indicating whether or not the peripheral device may be disconnected from the main system in a computer system. A sensing control section controls a display state of the display section in response sensing a switched state of the selecting section, and transmits corresponding signals to a central processing unit in response to sensing an operating state of the peripheral device. A transmission section selectively enables and disables transmission of interface signals between the peripheral device and the main system in a computer system in dependence upon a control signal provided from the sensing control section. The control signal is generated in response to the switched state of the selecting section.
