Low-Profile Computer’s Expansion-Card Slots
The low-profile computers have three expansion-card slots. The riser board has
two ISA expansion-card connectors and two PCI expansion-card connectors.
One PCI expansion-card connector and one ISA expansion-card connector
share a single expansion-card slot, resulting in a total of three expansion-card
slots (see Figure 1-6). The low-profile computers have a passive riser board,
with no PCI-to-PCI bridge.
Figure 1-6. Riser Board for the Low-Profile Computers

computer is different (see Figure 1-7). P1 is the network card connection on the
riser board. If the LED is on, the riser is receiving power, if it is off, the riser is
not receiving power.
