NOTE:
For two-position jumpers (3-post),
"RIGHT" is toward the bracket end of the SBC; "LEFT"
is toward the memory sockets.

JU89 3.3V MONITOR ENABLE
INSTALL = Enable 3.3V monitor.
REMOVE = Disable 3.3V monitor. *
NOTE: JU89 enables the 3.3 volt monitor, which monitors
the 3.3V power plane of the backplane. This voltage
is routed to the Single Board Computer via the PICMG® connector. The monitor
generates a RESET to the Single Board Computer if 3.3V is below tolerance.
If your system does not supply 3.3V to the backplane,
this jumper must be removed (disabled).

CPU SPEED JUMPERS
There are five jumpers (J140, J141,
W12, W12A and W99) which must be set correctly to allow
the Single Board Computer to take full advantage of the speed of the Pentium
microprocessor. The jumper settings depend on the bare
board revision level as indicated in the following charts.
