PCI (Peripheral Component Interconnect) Express Slot
PCI Express architecture provides a high performance graphics infrastructure 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
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.

Important
When adding or removing expansion cards, make sure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion card to
configure 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 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
