Important:
Electrostatic discharge (ESD) can damage your board, processor, disk drives, add-in
boards, and other components. Perform installation procedures at an ESD workstation
only. If such a station is not available, you can provide some ESD protection by wear-
ing an antistatic wrist strap and attaching it to a metal part of the system chassis. If
a wrist strap is unavailable, establish and maintain contact with the system chassis
throughout any procedures requiring ESD protection.
Important:
The Debug LED lights red until the operating system is being accessed. Power-off the
PC then unplug the power cord prior to installing any devices. Failure to do so will
cause severe damage to the motherboard and components.

JP1 is used to select the method of powering on the system. If you want the system to power
on whenever AC power comes in, set JP1 pins 4 and 6 to On. If you want to use the power
button, set pins 2 and 4 to On.
When using the JP1 “Power On” feature to power the system back on after a power failure
occurs, the system may not power on if the power lost is resumed within 5 seconds (power
flicker).
JP1 is also used to select the power supplied with the LCD panel.
Important:
Before powering-on the system, make sure that the power settings of JP1 match the
LCD panel’s specification. Selecting the incorrect voltage will seriously damage the
LCD panel.
