1.8.1

How to set jumpers

You can configure your motherboard to match the needs of your application by set-
ting the jumpers. A jumper is a metal bridge that closes an electrical circuit. It consists
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, you connect the pins
with the clip. To "open" (or turn off) a jumper, you remove the clip. Sometimes a
jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you connect
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when set-
ting jumpers.
1.8.1.1 CMOS and ME clear (JCMOS1)
The ASMB-585 motherboard contains a jumper that can erase CMOS data and reset
the system BIOS information. Normally this jumper should be set with pins 1-2
closed. If you want to reset the CMOS data, set JCMOS1 to 2-3 closed for just a few
seconds, and then move the jumper back to 1-2 closed. This procedure will reset the
CMOS to its default setting.

1.8.1.2 ME update (JME1)
The ASMB-585 contains a jumper that can update for ME firmware. Normally this
jumper should be set with pin 1-2 closed. If you want to update ME firmware, set
JME1 to 2-3 closed to disable ME for new ME firmware update.
