♦
PCI cards contain configuration registers that define resource information to the system during
startup. PCI cards do not require manual system configuration when installing the card. The
system’s BIOS detects the board’s presence during startup and reads information from the
board’s configuration registers to assign the necessary system resources.
♦
Non-compliant PCI cards do not contain configuration registers that allow the system to
automatically assign the necessary resources. These cards install in PCI slots, but you must
configure the system’s BIOS to assign system resources before installing the card.
♦
Non-PnP ISA cards do not contain registers that define the resource information to the system
during startup. Therefore, you must configure the system’s BIOS to define the card to the
system before installing the ISA card. This reserves system resources for the card.
♦
PnP cards are ISA cards that contain configuration registers like PCI cards. During startup,
the system’s BIOS automatically detects the installed card and assigns the necessary system
resources. Since a PnP card is ISA-based, you install it in an ISA slot.
NOTE
Assign system resources for any non-PnP ISA card and any non-compliant PCI
cards before installation. See the “Assigning System Resources” section below.
Each installed PCI card must draw less than 25 watts of power. The total allowable maximum
wattage for PCI cards is 125 watts. The PCI slots are limited to 25 watts power dissipation per the
Peripheral Component Interconnect Specification 2.1.
Identifying Expansion Card Slots
The system board has seven expansion card slots, located at the lower-left corner of the system
board. Slot 6 is a shared slot; you can install a PCI card or an ISA card in this slot, but not both.
Slot 6 - ISA (shared)
Slot 6 - PCI (shared)
Slot 5 - PCI
Slot 4 - PCI
Slot 3 - PCI
Slot 2 - PCI
Slot 1 - AGP
Slot 7 - ISA
See the System Board Manual for detailed information on the system board’s expansion slots.
