See Figure 1 for examples of the expansion cards. Figure 1. Expansion Cards 1 8-bit ISA expansion card 2 16-bit ISA expansion card 3 32-bit PCI expansion card Riser Boards The expansion-card connectors are located on a riser board that differs for each chassis: l Small-form-factor chassis riser board l Low-profile chassis riser board l Mini tower chassis riser board NOTE: If you choose one of the optional riser boards with ISA expansion-card connectors, evaluate the performance of any ISA expansion cards on a single system before you order other ISA riser boards. Dell recommends this step due to the broad range of ISA implementations in the computer industry. Small-Form-Factor Chassis Riser Board The small-form-factor chassis riser board has two PCI expansion-card connectors (see Figure 2). Figure 2.

The PCI riser board provides three PCI expansion card slots. The PCI/ISA riser board provides one PCI expansion slot, one ISA expansion slot, and one shared PCI/ISA expansion slot. Figure 3.
