xpansion Cards
Expansion cards can be installed on the computer’s riser
board
(see Figure 6-3). The vertical riser board plugs
into the RISER connector on the system board (see Fig-
ure 6-1) and is considered an extension of the system
board.
The system accommodates up to five expansion cards,
which can be a mix of 32-bit PCI expansion cards and
8- and 16-bit ISA expansion cards. (See Figure 6-2 for
examples of ISA and PCI expansion cards.)
Figure 6-2. Expansion Cards
Expansion Slots
Six expansion-card connectors reside on the riser board
(see Figure 6-3). Because two expansion-card connectors
share slot space, a maximum of five expansion cards can
be installed.
• Expansion-card connectors ISA1, ISA2, and ISA3
can accommodate 8- or 16-bit ISA expansion cards.
• Expansion-card connectors PCI1, PCI2, and PCI3
support PCI expansion cards. Because connector
PCI3 shares expansion-slot space with connector
ISA1, only one card of either type can be installed in
the common slot.

Installing an Expansion Card
Follow this general procedure to install an expansion
card:
1. If you are installing an ISA expansion card, enter
the ISA Configuration Utility (ICU) and add the
new expansion card to your configuration.
See Chapter 3, “Using the ISA Configuration Util-
ity,” for instructions.
NOTE: If you install a PCI or Plug and Play expan-
sion card, your system automatically performs any
required configuration tasks during the boot routine.
