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.
CNR (Communication Network Riser) Slot
The CNR slot allows you to insert the CNR expansion cards. CNR is a
specially designed network, audio, or modem riser card for ATX family motherboards. Its main
processing is done through software and controlled by the motherboard chipset.
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:
Order 1
PCI Slot 1 INT A#
PCI Slot 2 INT B#
PCI Slot 3 INT C#
PCI Slot 4 INT D#
PCI Slot 5 INT B#
PCI Slot 6 INT C#
Order 2 Order 3
INT B# INT C#
INT C# INT D#
INT D# INT A#
INT A# INT B#
INT C# INT D#
INT D# INT A#
