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 three 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
Four expansion-card connectors reside on the
riser board
(see Figure 6-3). Because two slot spaces are shared, a
maximum of three expansion cards can be installed on
the riser board.
•
Expansion-card connectors ISA2 (at the top of the
card) and ISA1 can accommodate 8- or 16-bit ISA
expansion cards.
•
Expansion-card connectors PCI1 and PCI2 support
PCI expansion cards.
NOTES: Connector PCI2 shares expansion-slot
space with connector ISA1, so only one card of
either type can be installed in the shared slot.
Because of the height of the hard-disk drive,
expansion-card connector PCI1 is limited to an
8.75-inch-long card
