Expansion 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 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.) Expansion Slots Nine expansion-card connectors reside on the riser board (see Figure 6-3).

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.)
Figure 6-2.
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.
