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 The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are 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 follows: PCI Slot 1 PCI Slot 2 PCI Slot 3 Order1 INT A# INT B# INT C# Order2 INT B# INT C# INT D# Order3 INT C# INT D# INT A# Order4 INT D# INT A# INT B# 9

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
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are 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 follows:
Order1
Order2
Order3
Order4
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
