xpansion Cards
Expansion cards can be installed on the computer's riser
board (see Figure 6-3). The horizontal 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 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.)

Expansion Slots

Nine expansion-card connectors reside on the riser board
(see Figure 6-3). Because two slot spaces are shared, a
maximum of seven expansion cards can be installed on
the riser board.
•
Expansion-card connectors ISA1, ISA2, ISA3, and
ISA4 support 8- or 16-bit ISA expansion cards.
•
Expansion-card connectors PCI1, PCI2, PCI3, PCI4,
and PCI5 support 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.
