Expansion Boards
This section describes in detail the steps needed to
install expansion boards in the system.
Read the “ESD Precautions” section earlier in this
chapter before proceeding.
There are three types of expansion boards:
• EISA
• ISA
• PCI
Each expansion board has a different type of connector
See Figure Figure 2-15.
An ISA board has a single row of contacts along its
connectors. There is usually a single notch in the
connector.
An EISA board has a double row of tightly spaced
contacts along its connector. There are usually six
notches (five small ones and one large one) in the
connector.
A PCI board has a single row of tightly spaced contacts
along its connectors. There is usually a single notch in
the connector.
