NOTE:
For two-position jumpers (3-post), "TOP" is toward the memory sockets; "BOTTOM" is toward the edge fingers.

* = default value

JU1 LCD VIEWING ANGLE
Install on the TOP for -5 degrees to -10 degrees.
Install on the BOTTOM for 0 degrees to -5 degrees.
Remove if your LCD panel does not provide a viewing angle selection. *

JU8 PASSWORD CLEAR
Install for one power-up cycle to reset the password to the default (null password).
Remove for normal operation. *

JU9/JU9A SCSI TERMINATION - CHANNEL 0
These two jumpers may be used to enable or disable
on-board active termination for the Ultra3 SCSI interface.

	JU9	JU9A
Enable active termination	Install *	Install *
Disable active termination	Remove	Remove
Enable upper byte only	Remove	Install

JU10/JU11 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.

	JU10	JU11
Program All (Boot and Main)	Top	Top
Normal PnP (Program Main Block)	Top *	Bottom *
Write Protect	Bottom	Bottom

JU12 CMOS CLEAR
INSTALL = Clear CMOS
REMOVE = Operate *

NOTE: The CMOS Clear jumper works on power-up. To clear the CMOS, power down the system, install the jumper, then turn the power back on. CMOS is cleared during the POST routines. Wait for AMIBIOS to display a "CMOS Checksum Bad" message; then power down the system again and remove the jumper before the next power-up.

JU13 LCD BACKLIGHT ENABLE
Install on the LEFT for "low active" enable.
Install on the RIGHT for "high active" enable. *

JU15 3.3V MONITOR ENABLE
INSTALL = Enable 3.3V monitor
REMOVE = Disable monitor *

NOTE: JU15 enables the 3.3V 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).

JU16 WATCHDOG TIMER
TOP = Enable watchdog
BOTTOM = Normal reset*

JU19 SCSI ACTIVITY LED ENABLE

INSTALL=	Light the hard drive LED for SCSI drive activity *
REMOVE=	No SCSI drive (i.e., the SCSI controller is not being used)

JU20 SCSI TERMINATION - CHANNEL 1

INSTALL=	Disable on-board active termination for the Ultra Wide SCSI interface
REMOVE=	Enable active termination. *

W7 SPREAD SPECTRUM ENABLE
Install to enable spread spectrum for the processor oscillator, which may reduce EMI levels at some frequencies. *
Remove to disable.

NOTE: The W7 jumper is included on SBCs with revision C-02M or later. Revisions of B-01 and earlier do not have this jumper.

On revisions E-04 or later, the default for W7 is "enabled"; on earlier revisions, the default was "disabled."

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