Expansion cards are installed on the computer’s riser board (see Figure 6-3). The riser
board plugs into the RISER connector on the system board (see Figure 6-1) and is
considered an extension of the system board.
The system accommodates up to five expansion cards, which can be a mix of 32-bit
PCI expansion cards and 8- and 16-bit ISA expansion cards. (See Figure 6-2 for exam-
ples of ISA and PCI expansion cards.)
