ABSTRACT:
An error preventing system for card service interrupt signals in a personal computer using a plurality of card interface controllers, which includes at least two PCMCIA (Personal Computer Memory Card International Association) cards, at least two PCICs (PCMCIA Card Interface Controllers) which each output an interrupt signal to service the respective PCMCIA card and operate a portable computer through this process, and a signal-correction unit which inputs the interrupt signal output from the PCICs and outputs the corresponding signals after processing the outputted interrupt signals of logic OR. For preventing an error and a system-halt while prohibiting the collision between signals to transmit the accurate card service interrupt signal in case each PCIC outputs a respective card service interrupt signal.
