Hardware Setup Slots The mainboard provides one AGP slot and five 32-bit PCI bus slots. AGP (Accelerated Graphics Port) Slot The AGP slot allows you to insert the AGP graphics card. AGP is an interface specification designed for the throughput demands of 3D graphics. It introduces a 66MHz, 32-bit channel for the graphics controller to directly access main memory. The slot supports 8x/4x AGP card. AGP Slot 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 Slots 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 INT A# ~ INT D# pins as follows: PCI Slot 1 PCI Slot 2 PCI Slot 3 PCI Slot 4 PCI Slot 5 Order 1 INT A# INT B# INT C# INT D# INT B# Order 2 INT B# INT C# INT D# INT A# INT C# Order 3 INT C# INT D# INT A# INT B# INT D# Order 4 INT D# INT A# INT B# INT C# INT A# 2-23

Hardware Setup
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 INT
A# ~ INT D# pins as follows:
Slots
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card.
AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory. The slot supports 8x/4x AGP card.
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.
The mainboard provides one AGP slot and five 32-bit PCI bus slots.
