Identifying adapter card connectors

You can install PCI adapter cards into the card connectors on the system board.
Use the following table to help you determine the type and length of adapter cards
that you can install in the card connectors.
Refer to the section “Adding and removing adapter cards” on page8-4 for
instructions on adding or removing cards.

Setting a jumper

When you install an adapter card, you may have to set s wi tch es or mo v e ju mpers to
make the card work properly. Plug and Play cards normally require no changes, but
other cards might. Refer to the documentation that came with the new hardware to
determine if changes to jumper or switch settings are required.
The following figures show how to set a jumper. Position A shows closing pins 1-2
while position B shows closing pins 2-3. Pin 1 of a jumper is usually marked by a
solid white line beside the pin.
