Jumper Options
This section provides instructions on how to configure the motherboard by setting
jumpers, and also outlines the default motherboard settings and options for each
jumper.
1.9.1
Setting Jumpers
The motherboard can be configured according to the application requirements with
the setting of jumpers. A jumper is a metal bridge used to close an electrical circuit.
Jumpers typically consist of two metal pins and a small metal clip (often protected by
a plastic cover) that slides over the pins to connect them. To “close” (or turn ON) a
jumper, connect the pins with the clip. To “open” (or turn OFF) a jumper, simply
remove the clip. Some jumpers comprise a set of three pins, labeled 1, 2, and 3. With
these jumpers, simply connect either Pins 1 and 2, or Pins 2 and 3. A pair of needle-
nose pliers may be necessary for setting jumpers.
1.9.2
CMOS Mode Selection (JRTCTEST1)
The AIMB-215 motherboard contains a jumper that can erase CMOS data and reset
the system BIOS information. This jumper is typically set with Pins 1 and 2 being
closed. To reset the CMOS data, set J1 to Pins 2 and 3 as closed for a few seconds
before moving the jumper back to Pins 1 and 2 as closed. This procedure resets the
CMOS to its default settings.
