PCI Express Slots
The PCI Express slots, as a high-bandwidth, low pin count, serial, interconnect technology,
support Intel highest performance desktop platforms utilizing the Intel Pentium 4 processor with
HT 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 designs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics
controllers, while PCI Express x1 supports transfer rate of 250 MB/s.
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.
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:
Order1
PCI Slot 1 INT C#
PCI Slot 2 INT D#
PCI Slot 3 INT A#
