Midsize Computer’s Expansion-Card Slots
The midsize computers have five expansion-card slots. The riser board is
offered in two options. Option 1 is a passive riser board, with no PCI-to-PCI
bridge. Option 1 has three ISA expansion-card connectors and three PCI
expansion-card connectors. One PCI expansion-card connector and one ISA
expansion-card connector share a single expansion-card slot, resulting in a total
of five expansion-card slots (see Figure 1-7). Option 2 is an active riser board,
with a PCI-to-PCI bridge. Option 2 has two ISA expansion-card connectors and
five PCI expansion-card connectors. Two PCI/ISA expansion-card connector
pairs each share an expansion-card slot, again resulting in a total of five
expansion-card slots (see Figure 1-8).
