An asterisk (*) 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. JU7 COMBO I/O (P5A) SPEAKER CONNECT (Also refer to JU18 - Combo I/O Reset Connect.) INSTALL= Connect speaker data signal to pin 8 of Combo I/O connector (P5A) * REMOVE= Disconnect JU8 Password Clear Install for one power-up cycle to reset the password to the default (null password). Remove for normal operation. * JU9 CRT TYPE SELECT LEFT = Monochrome RIGHT = Color * 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.

To clear the CMOS, power down the system, install the jumper, then turn the power back on. CMOS is cleared during the POST routines. Then power down the system again and remove the jumper before the next power-up. JU13 SCSI TERMINATION ENABLE (Not available on BASIC model) INSTALL= Disable on-board active termination for SCSI interface REMOVE= Enable * JU14 FAN SPEED MONITOR This jumper must be removed (disabled). 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 LEFT = Normal reset * RIGHT = Enable watchdog JU17 INTERRUPT 12 (IRQ12) SELECT INSTALL = IRQ12 dedicated to PS/2 mouse * REMOVE = IRQ12 available for system use JU18 COMBO I/O (P5A) RESET CONNECT (Also refer to JU7 = Combo I/O Speaker Connect.) INSTALL= Connect reset data signal to pin 1 of Combo I/O connector (P5A) * REMOVE= Disconnect JU19 SCSI ACTIVITY LED ENABLE (not available on BASIC model) INSTALL= Light the hard drive LED for SCSI drive activity* REMOVE= No SCSI drive (i.e., the SCSI controller is not being used) JU20 DUAL PROCESSOR ENABLE INSTALL = Enable dual processor operation * REMOVE = Single processor operation CPU SPEED JUMPERS There are four jumpers (W3, W4, W5 and W6) which must be set correctly to allow the SBC to take full advantage of the speed of the Pentium II/III microprocessor. These jumpers must be set as specified below.

LED/Connector Description Link/Activity LED Green LED which indicates the link status. Off = The Ethernet interface did not find a valid link on the network connection. Transmit and receive are not possible. On = The Ethernet interface has a valid link on the network connection and is ready for normal operation. (solid) The Speed LED identifies connection speed. On = Indicates network transmit or receive activity. (flashing) Speed LED Amber LED which identifies connection speed. Off = Indicates a 10Mb/s connection. On = Indicates a 100Mb/s connection. RJ-45 Network The RJ-45 network connector requires a category 5 (CAT5) unshielded twisted-pair (UTP) 2-pair cable for a 100-Mb/s network connection or a category 3 (CAT3) or higher UTP 2-pair cable for a Connector 10-Mb/s network connection.

Minimum memory size is 8MB. The System BIOS automatically detects memory type, size and speed. The SBC uses industry standard 64-bit or 72-bit wide gold finger DIMM DRAM in two 168-pin DIMM sockets. NOTE: Memory can be installed in one or both DIMM sockets. If only one DIMM module is used, it must be populated in the top DIMM socket (Bank 1 - BK1). If two modules are used, they must be the same DIMM type, but may be different sizes (see table below). EDO DIMMs are not supported. All DIMMs must have gold contacts. The SBC supports DIMM memory modules which are PC-100 compliant and have the following features: • 168-pin DIMMs with gold-plated contacts • 100MHz SDRAM • Non-ECC (64-bit) or ECC (72-bit) memory • 3.3 volt only • Single or double-sided DIMMs in the sizes listed below • Buffered or Registered configuration DIMM Size DIMM Type Non-ECC ECC 8 MB Unbuffered 1M x 64 1M x 72 16 MB Unbuffered 2M x 64 2M x 72 32 MB Unbuffered 4M x 64 4M x 72 64 MB Unbuffered 8M x 64 8M x 72 128 MB Unbuffered 16M x 64 16M x 72 256 MB Registered 32M x 64 32M x 72 512 MB Registered 64M x 64 64M x 72 ** ** DP2GX models only All memory components and DIMMs used with the SBC must be PC-100 compliant, which means that they comply with Intel's PC SDRAM specifications. These include the PC SDRAM Specification (memory component specific), the PC Unbuffered DIMM Specification, the PC Registered DIMM Specification and the PC Serial Presence Detect Specification.
