MS-7145 M-ATX Mainboard
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, supports 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 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. W hen 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.
W hen 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, 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:
Order 1
PCI Slot 1 INT E#
PCI Slot 2 INT F#
PCI Slot 3 INT G#
