Jumpers
Jumpers are made by pin headers and plastic connecting caps for the purpose of
customizing your hardware. Doing so requires basic knowledge of computer
hardware, be sure you understand the meaning of the jumpers before you
change any setting.  The onboard jumpers are normally set to their default with
optimized settings.
On the mainboard, normally there is a bold line marked beside pin 1 of the
jumper, sometimes, there are numbers also. If we connect (short) plastic cap to
pin 1 and 2, we will say set it at 1-2, and when we say jumper is open, that
means no plastic cap connected to jumper pins.
