▍ Hardware Setup PCI (Peripheral Component Interconnect) Slot The PCI slot supports LAN card, SCSI card, USB card, and other add-on cards that comply with PCI specifications. 32-bit PCI Slot Important When adding or removing expansion cards, make sure that you unplug the power supply first. Meanwhile, read the documentation for the expansion card to configure any necessary hardware or software settings for the expansion card, such as jumpers, switches or BIOS configuration. PCI Interrupt Request Routing The IRQ, acronym 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 pins as follows: PCI Slot1 PCI Slot2 PCI Slot3 Order1 INT F# INT G# INT A# Order2 INT G# INT H# INT B# Order3 INT H# INT E# INT C# Order4 INT E# INT F# INT D# 2-22

PCI (Per±pheral Component Interconnect) Slot
The PCI slot supports LAN card, SCSI card, USB card, and other add-on cards that
comply w±th PCI spec±ficat±ons.
32-b±t PCI Slot
Important
When add±ng or remov±ng expans±on cards, make sure that you unplug the power sup-
ply first. Meanwh±le, read the documentat±on for the expans±on card to configure any
necessary hardware or software sett±ngs for the expans±on card, such as jumpers,
sw±tches or BIOS configurat±on.
PCI Interrupt Request Rout±ng
The IRQ, acronym of ±nterrupt request l±ne and pronounced I-R-Q, are hardware l±nes
over wh±ch dev±ces can send ±nterrupt s±gnals to the m±croprocessor. The PCI IRQ p±ns
are typ±cally connected to the PCI bus p±ns as follows:
Order1
Order2
Order3
Order4
