Hardware Setup Slots The motherboard provides one AGP slot, three 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, 32bit channel for the graphics controller to directly access main memory. 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.

Hardware Setup
Slots
The motherboard provides one AGP slot, three 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 specifi-
cation designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-
bit channel for the graphics controller to directly access main memory.
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:
Order 1
Order 2
Order 3
Order 4
