Six expansion-card connectors reside on the riser board (see Figure 6-3). Because two of the expansion-card connectors share an expansion-slot space, a maximum of five expansion cards can be installed.

‡

Expansion-card connectors ISA1–ISA3 (at the top of the card) support 8- or 16-bit ISA expansion cards.

Expansion-card connectors PCI1–PCI3 support 32-bit PCI expansion cards.

NOTE: Connector PCI3 shares expansion-slot space with connector ISA1, so only one card of either type can be installed in the shared slot.
