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

NOTE: JU88 and JU88A must be set to the same function
(either mouse or keyboard) for the peripheral to function
properly.
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 SBC via the PICMG® connector. The monitor
generates a RESET to the SBC if 3.3V is below tolerance.
If your system does not supply 3.3V to the backplane,
this jumper must be removed (disabled).

JU110/JU115 SYSTEM FLASH ROM
OPERATIONAL MODES
The Flash ROM has two programmable
sections: the Boot Block for "flashing" in the BIOS
and the Main Block for the executable BIOS and PnP parameters.
Normally only the Main Block is updated when a new BIOS
is flashed into the system.

CPU SPEED JUMPERS
There are five jumpers (J140, J141,
W12, W12A and W99) which must be set correctly to allow
the SBC 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.
