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

JU84 P5A SPEAKER CONNECT

INSTALL=	Connect speaker data signal to pin 8 of Combo I/O connector (P5A) *
REMOVE=	Disconnect

JU85 P5A RESET CONNECT

INSTALL=	Connect reset data signal to pin 1 of Combo I/O connector (P5A) *
REMOVE=	Disconnect

JU86 INTERRUPT 12 (IRQ12) SELECT
INSTALL = Dedicate IRQ12 to PS/2 mouse. *
REMOVE = Make IRQ12 available for system use.

JU88 P4B PS/2 MOUSE/KEYBOARD INTERFACE DATA SELECT
LEFT = Keyboard data
RIGHT = Mouse data *

JU88A P4B PS/2 MOUSE/KEYBOARD INTERFACE CLOCK SELECT
LEFT = Mouse clock *
RIGHT = Keyboard clock

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.

	JU110	JU115

Write Protect	Top	Top

JU120 SCSI TERMINATION

INSTALL=	Disable on-board active termination for SCSI interface
REMOVE=	Enable *

JU900 VGA INTERRUPT ENABLE
INSTALL = Enable VGA interrupt
REMOVE = Disable *

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.

Bare Board Revision Levels Prior to L-A-09:

Bare Board Revision Levels L-A-09 and Above:

NOTE:
Pin 1 on the connectors is indicated by the square pad on the PCB.
