Identifying adapter card 
connectors
You can install ISA or 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 
page 7-3 for instructions on adding or removing cards.
Setting a jumper
When you install an adapter card, you may have to set 
switches or move jumpers to make the card work properly. 
Plug and Play cards normally require no changes, but other 
cards do. 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.
