Nine expansion-card connectors reside on the riser board (see Figure 6-3). Because two expansion slots are shared, a maximum of seven expansion cards can be installed on the riser board.

Expansion-card connectors ISA1–ISA4 support 8- or 16-bit ISA expansion cards.

Expansion-card connectors PCI1–PCI5 support 32-bit 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.
