PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs.
When adding or removing expansion cards, make sure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion card
to make any necessary hardware or software settings for the expansion card,
such as jumpers, switches or BIOS configuration.
PCI Interrupt Request Routing

hardware lines over which devices can send interrupt signals to the
microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT A#
~ INT D# pins as follow:
Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT A# INT B# INT C# INT D#
PCI Slot 2 INT B# INT C# INT D# INT A#
PCI Slot 3 INT C# INT D# INT A# INT B#
