10262090001 Revision B 2–22 Adding cards to the System Controller
Connect JP2 pins 2 and 3 for normal CMOS operation. In the
event that CMOS settings prevent the AIReach OS Controller
from booting, you can clear the CMOS settings by placing a
jumper over JP2 pins 1 and 2. Do this only in an emergency.
Clearing the CMOS helps correct only certain hardware problems.
Operating system or software problems cannot be remedied
through clearing the CMOS. If it is necessary to clear CMOS
settings, see HNS document 1027630 for the proper settings.
