Motherboard jumper settings
The motherboard is fitted with a number of jumpers that are
used to configure the operation of the system. The following
illustration shows the position of the jumpers.
All the jumpers are three pin. These can be configured with a
jumper clip connecting the centre pin and either of the two
end pins. The function of each jumper is described in the
following paragraphs, text printed on the motherboard
alongside each jumper identifies the positions described below.
Jumper J2 - CMOS clear
This jumper is used to clear the motherboard configuration
memory. During normal operation the jumper clip should be
in the position marked NOR on the motherboard.
If you have reason to clear the configuration memory then,
with the system powered down, move the jumper clip to the
position marked CLR for a few seconds.
