System for detecting a peripheral device

摘要

A system for detecting a peripheral device is used to detect whether the peripheral device is completely inserted into a peripheral interface slot of a mother board before booting. When the peripheral device is inserted into the peripheral interface slot, the system judges whether the peripheral device is completely inserted into the peripheral interface slot according to a potential of fins of the peripheral interface slot. If the system detects that the peripheral device has not been completely inserted into the peripheral interface slot before booting, a booting procedure of the mother board is interrupted and an alarm signal is output.
