Expansion Cards
Expansion cards are installed on the computer's riser board (see Figure 3). The riser board plugs into the
RISER connector on the system board (see Figure 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 2 for examples of ISA and PCI expansion cards.)

Expansion Slots
Four expansion-card connectors reside on the riser board (see Figure 3). Because two expansion slots are
shared, a maximum of three expansion cards can be installed on the riser board.
Expansion-card connectors ISA1–ISA2 support 8- or 16-bit ISA expansion cards.
Expansion-card connectors PCI1–PCI2 support 32-bit PCI expansion cards.
NOTES: On shared expansion slots, only one card of either type can be installed in the common slot.
An expansion-card installed in connector PCI1 cannot exceed 8.75 inches in length.
