An asterisk (*) indicates the default value of each jumper. NOTE: For two-position jumpers (3-post), "TOP" is toward the memory sockets; “BOTTOM” is toward the edge fingers. JU6 Thermal Throttling 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. NOTE: Critical temperature is determined by the processor and cannot be altered by the end user. 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. JU8 Password Clear Install for one power-up cycle to reset the password to the default (null password). Remove for normal operation. * JU9 SCSI Termination This jumper may be used to enable or disable on-board active termination for the Ultra160 SCSI interface. Install on the TOP to enable active termination * Install on the BOTTOM to allow the AIC-7892 to control termination. Remove to disable active termination. JU10/11 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.

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 Settings Wrong" message; then power down the system again and remove the jumper before the next power-up.

The System BIOS automatically detects memory type, size and speed. The SBC uses industry standard 64-bit wide gold finger PC1600 or PC2100 memory modules in 184- pin DIMM sockets. NOTE: Memory modules can be installed in one or both DIMM sockets. If only one DIMM module is used, it should be populated in the top DIMM socket (Bank 2 - Bk2). If two modules of different speeds are used, the 845GV chipset sets the memory interface speed to the speed of the slower DIMM module. Registered DIMMs are not supported. 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 • Non-ECC (64-bit) DDR memory • Unbuffered configuration • X8, x16 construction • Non-stacked (NS) NOTE: Intel's DDR memory interface design guidelines for the 845GV chipset validate the use of non- stacked DIMM modules. Therefore, the T4G, which uses the 845GV chipset, supports only non-stacked DIMMs in its standard system BIOS.
