Auto Power On and Restore BIOS Optimal Defaults (SW1)
If dip1 of SW1 (SW1-1) is set to OFF position, the system will be automatically power on
without pressing soft power button. If this jumper is set to ON position, it is necessary to
manually press soft power button to power on the system.
The dip2 of SW1 (SW1-2) is for restoring BIOS default status. Flip SW1-2 to ON position
for a few seconds then flip it back to OFF position. Doing this procedure can restore
BIOS optimal defaults.
