2.8 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.
