Expansion Cards: Dell™ OptiPlex™ GX100 System User's Guide
Overview
OptiPlex GX100 systems can accommodate a mix of 32- bit Peripheral Component Interconnect (PCI) expansion cards and, optionally, 16-bit and
8-bit Industry-Standard Architecture (ISA) expansion cards, depending on the chassis and riser board . See Figure 1 for examples of the expansion
cards.

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
Small-Form-Factor Chassis Riser Board
The small-form-factor chassis riser board has two PCI expansion-card connectors (see Figure 2).
Figure 2. Small-Form-Factor Chassis Riser Board
Low-Profile Chassis Riser Board
The low-profile chassis is available with either a PCI riser board (see Figure 3 ) or a PCI/ISA riser board (see Figure 4 ). 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.

1 8-bit ISA expansion card
2 16-bit ISA expansion card
3 32-bit PCI expansion card
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.
