Set both of the jumpers select AT or ATX power mode for the
WAFER-PV-D5252/D4252/N4552. AT power mode limits the system to on/off. ATX allows
the system to use various power saving states and enter a standby state, so the system
can be turned on remotely over a network. The settings on both jumpers should be the
same.

If the WAFER-PV-D5252/D4252/N4552 fails to boot due to improper BIOS settings, the
clear CMOS jumper clears the CMOS data and resets the system BIOS information. To do
this, use the jumper cap to close pins 2 and 3 for a few seconds then reinstall the jumper
clip back to pins 1 and 2.
