xpansion Cards
Expansion cards are installed on the computer's riser
board (see Figure 6-3). The riser board plugs into the
RISER connector on the system board (see Figure 6-1)
and is considered an extension of the system board.
The system accommodates up to seven 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
Nine expansion-card connectors reside on the riser board
(see Figure 6-3). Because two expansion slots are shared,
a maximum of seven expansion cards can be installed on
the riser board.

Expansion-card connectors PCI1–PCI5 support
32-bit PCI expansion cards.
NOTE: Because connector PCI4 shares expansion-
slot space with connector ISA1, and PCI5 shares
with ISA2, only one card of either type can be
installed in each of the two shared slots.

Installing an Expansion Card
Follow this general procedure to install an expansion card:
1.
If you are installing a non-Plug and Play ISA
expansion card, enter the ISA Configuration Util-
ity (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.
2.
Prepare the expansion card for installation, and
remove the computer cover according to the
instructions in "Removing the Computer Cover"
in Chapter 5.
CAUTION: See "Protecting Against Electro-
static Discharge" in the safety instructions at
the front of this guide.

card for information on configuring the card, making
