Mini Tower Computer’s Expansion-Card Slots
The mini tower computers have seven expansion-card slots. The riser board has
four ISA expansion-card connectors and five PCI expansion-card connectors.
Two PCI expansion-card connectors share expansion-card slots with ISA con-
nectors, resulting in a total of seven expansion-card slots (see Figure 1-9). The
riser board is active, incorporating PCI-to-PCI bridging.
