The setup of the configuration jumpers on the SBC is described below.

* indicates the default value of each jumper.

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

XPT PROCESSOR BOARD

JU6 THERMAL THROTTLING ACTIVITY LED
If the processor core gets to a critical temperature, it slows itself down to half its normal speed. This jumper sets the way in which the LED displays in response to this self-limiting mode.

Install for real-time activity. The LED lights only when the processor is operating in slow-power mode.*

Remove for latched activity. The LED lights and stays on once the processor has gone into slow-power mode.

NOTE: Critical temperature is determined by the processor and cannot be altered by the user.

XPT I/O BOARD

JU1/JU2 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.

	JU1	JU2
All Blocks Write Enabled	Remove *	Remove *
Boot Block Protected	Install	Remove
Block 2-16 Protected	Remove	Install

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

JU9/JU9A/JU9B SCSI TERMINATION - CHANNEL 0
These three jumpers may be used to enable or disable on-board active termination for the Ultra320 SCSI interface - Channel 0.

JU20/JU20A/JU20B SCSI TERMINATION - CHANNEL 1
These three jumpers may be used to enable or disable on-board active termination for the Ultra320 SCSI interface - Channel 1.

JU20 JU20A JU20B

JU12 CMOS CLEAR
Install on the RIGHT to clear.
Install on the LEFT to 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. Wait for at least two seconds and turn the power off. Then remove the jumper and turn the power on. When AMIBIOS displays the "CMOS Settings Wrong" message, press F1 to go into the BIOS Setup Utility, where you may reenter your desired BIOS settings, load optimal defaults or load failsafe defaults.

NOTE: If the CMOS settings are cleared, the processor may reset to the safe mode, resulting in a reduction in execution speed which affects overall system performance. After clearing CMOS, you should always check the operating speed and reset it if necessary. To reset the SBC to the correct operating speed, use the CPU Ratio CMOS Setting option on the CPU Configuration screen. See the Advanced Setup chapter of this manual for further details.

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

The Double Data Rate (DDR) memory interface consists of two channels, each terminating at a pair of DIMM sockets, providing a total of four memory sockets. The SBC supports auto detection of up to 8GB of memory. The System BIOS automatically detects memory type, size and speed.

The SBC uses industry standard 72-bit wide gold finger PC1600 or PC2100 memory modules in four 184-pin sockets.

NOTE: The four memory sockets on the SBC must be installed in pairs, beginning with the sockets in Bank 1 (i.e., BK1A and BK1B), and must contain ECC registered PC1600 or PC2100 DIMMs. All DIMMs must be the same speed (PC1600 or PC2100). The modules within a pair must be the same size; however, if two pairs are used, each pair can contain a different size module. DIMM sizes can range from 128MB to 2GB each. All memory modules must have gold contacts.

The SBC supports DIMMs which are PC1600/PC2100 compliant and have the following features:

184-pin with gold-plated contacts
ECC (72-bit) memory
Registered configuration

The following DIMM sizes are supported:

DIMM Size	DIMM Type	ECC
128MB	Registered	16M x 72
256MB	Registered	32M x 72
512MB	Registered	64M x 72
1GB	Registered	128M x 72
2GB	Registered	256M x 72
