board, with a PCI-to-PCI bridge. Option 2 has two ISA expansion-card connec-

connector pairs each share an expansion-card slot, again resulting in a total of

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.
