Expansion Cards Expansion cards can be installed on the computer's riser board (see Figure 6-3). The vertical 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 three expansion cards, which can be a mix of 32-bit PCI expansion cards and 8and 16-bit ISA expansion cards. (See Figure 6-2 for examples of ISA and PCI expansion cards.) 8-bit ISA expansion card Expansion Slots Four expansion-card connectors reside on the riser board (see Figure 6-3).

onnector PCI2 shares expansion-slot
space with connector ISA1, so only one card of

ecause of the height of the hard-disk drive, expan-

long card.
