METHOD FOR INSTALLING COMPUTER CARD, INSTALLATION DETECTION SYSTEM, AND COMPUTER PROGRAM

PROBLEM TO BE SOLVED: To provide a switch that detects when a computer expansion card is added, removed or changed. SOLUTION: During operation, the switch is held in a depressed position by contact with a card. If the card is removed, the switch is raised and, when a second card is installed in the same slot, the switch is again depressed. The depression of the switch triggers a change signal that initiates the introduction of power to the slot for a period of time long enough for a hypervisor to detect the new device. A delay between a release and subsequent depression of the switch is set such that when the switch is released enough time is provided to firmly seat a different card in the planar device. Following the delay, power is supplied to the slot so that the hypervisor detects the card and updates the current configuration parameters. COPYRIGHT: (C)2010,JPO&INPIT
