board, with a PCI-to-PCI bridge. Option 2 has two ISA expansion-card connec-
tors and five PCI expansion-card connectors. Two PCI/ISA expansion-card
connector pairs each share an expansion-card slot, again resulting in a total of
five expansion-card slots (see Figure 1-8).
Both riser board options include the P1 connector (for connecting the NIC to
the riser board cable) and an LED. If the LED is on, the riser board is receiving
power; if off, the riser board is not receiving power.
