Slots

2.8.1

PCI (Peripheral Component Interconnect)
Express Slot

PCI Express architecture provides a high performance graphics infra-
structure for Embedded Platforms doubling the capability of existing
AGP 8x designs with transfer rates of 4.0 GB/s over a PCI Express x16
lane for graphics controllers

2.8.2

PCI (Peripheral Component Interconnect) Slot

The PCI slot supports LAN cards, SCSI cards, USB cards, and other
add-on cards that comply with PCI specifications. At 32 bits and 33 MHz,
it yields a throughput rate of 133 MBps.

2.8.3

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
pins as follows:

Order 1

Order 2

Order 3

Order 4

32-bit PCI1

INT A#

INT B#

INT C#

INT D#

Note

When adding or removing expansion cards, make sure that
you unplug the power supply first. Meanwhile, read the docu-
mentation for the expansion card to configure any necessary
hardware or software settings for the expansion card, such as
jumpers, switches or BIOS configuration.
