PCI Interrupt Request Routing

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hard-

ware 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:

The motherboard provides one PCI Express x16 slot and three 32-bit PCI bus

slots.

PCI Express Slots

The PCI Express slot, as a high-bandwidth, low pin count, serial, interconnect

technology.

PCI Express architecture provides a high performance I/O infrastructure for

Desktop Platforms with transfer rates starting at 2.5 Giga transfers per second over

a PCI Express x1 lane for Gigabit Ethernet, TV Tuners, 1394 controllers, and general

purpose I/O. Also, desktop platforms with PCI Express Architecture will be designed

to deliver highest performance in video, graphics, multimedia and other sophisticated

applications. Moreover, PCI Express architecture provides a high performance graphics

infrastructure for Desktop Platforms doubling the capability of existing AGP8x de-

signs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics

controllers.

You can insert the expansion cards to meet your needs. When adding or

removing expansion cards, make sure that you unplug the power supply first.

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.
