ABSTRACT:
A circuit board system for connecting with at least an expansion card that includes a Programmable Logic Device (PLD) electrically coupled to the expansion slot. The PLD is configured to detect whether the expansion card is compatible with the circuit board system. If the PLD detects that the expansion card is not compatible with the circuit board system, the logic controller cuts off the connection between the main power supply and the expansion slot.
