Hyper-Threading Technogy Intel's Hyper-Threading technology makes a single Intel ® Xeon™ processor appear as two logical processors. The operating system and application must be optimized for Hyper-Threading. The ELK-SBC6090-108's two physical Intel ® Xeon™ processors will function as four logical processors in applications optimized for Hyper-Threading.
Chipset The Intel ® E7501 chipset provides support for dual Intel ® Xeon ™ processors, a 400/533 system bus, and PC1600 or PC2100 DDR memory with ECC.
Bus Speed ISA:16-bit/8MHz, PCI:32-bit/33MHz, 32-bit/66MHz
64-bit/33MHz, 64-bit/66MHz, PCI-X: 64-bit/66MHz, 64-bit/100MHz or 64-bit/133MHz Hub Link 2.0 : 1GB/s , System/FSB : 400MHz, 533MHz
Bios (Flash) AMIBIOS8 ® has built-in advanced CMOS setup for system parameters, peripheral management for configuring on-board peripherals, PCI-to-PCI bridge support and PCI interrupt steering. Supports flash devices for BIOS upgrading via floppy interface. Also provides integrated support for USB mass storage devices such as USB, CD-ROM, CD-RW, etc. Custom BIOSs are available upon request.
Cache Memory Each Intel ® Xeon™ processor supports a 512K integrated on-die Advanced Transfer Cache (L2). The cache is an 8-way set associative cache running at full processor core frequency. The Execution Trace Cache (L1) is a 12K data cache that stores thousands of decoded micro-operations. The purpose of this L1 cache is to remove decoder latency from the processor's main execution path, resulting in increased processor performance.
Main Memory The DDR memory interface on the ELK-SBC6090-108 consists of two channels, each terminating at a pair of DIMM module sockets. The ELK-SBC6090-108 supports auto detection of up to 8GB of memory. The system BIOS automatically detects memory type, size and speed. The four memory sockets on the SBC must be populated in pairs, beginning with the sockets in Bank 1, 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. The maximum memory capacity of the ELK-SBC6090-108 is 8GB and the minimum interface bandwidth is 1600MB/s.
Error Checking and Correction
 The memory interface supports ECC modes via BIOS setting for multiple-bit error detection and correction of all errors confined to a single nibble.
PCI-X Bus Interface The PCI-X bus interface supports a 64-bit PCI-X backplane interface running at either a 66MHz, 100MHz or 133MHz bus speed.
PCI Bus Interface The PCI bus interface supports either a 32-bit/33MHz or a 64-bit/66MHz PCI backplane interface.
ISA Bus Interface
 The ELK-SBC6090-108 provides a 16-bit ISA bus interface to the backplane for legacy ISA slots.
System hardward Monitor The Winbond W83783S chip supports hardware monitoring. The functions monitored are voltage, fan speed and temperature. The ELK-SBC6090-108 hardware monitor software allows the user to program the monitor limits to provide trigger points for the application software. This allows the application program to monitor these trigger points in order to send system alert messages or perform corrective actions.
Floppy Drive Interface Supports up to two floppy disk drives in combinations of 360K to 2.88MB.
Ultra XGA Video Interface The ATI M6-C16H video controller enables 2D/3D video acceleration and provides 16MB of integrated video DDR memory. The video controller supports pixel resolutions up to 1600 x 1200. Software drivers are available for most popular operating systems.
Serial Interface The Super I/O controller supports two full-function serial ports with independently programmable baud rates. The controller has two high-speed, NS16C550 compatible, UARTs with Send/Receive 16-Byte FIFOs. The IRQ for each serial port has BIOS selectable addressing.
Dual Ethernet Interfaces The ELK-SBC6090-108 has an internal PCI-X bus that connects to Intel's 82546EB Ethernet Controller chip. This board design feature provides high-speed dual Gigabit Ethernet on LAN ports 1 and 2. The ELK-SBC6090-108 also supports existing 10Mb or 100Mb per second Ethernet networks over the same internal PCI-X bus. RJ-45 connectors located on the I/O bracket provide the mechanical interface to the Ethernet networks.
USB Interfaces(Dual) The ELK-SBC6090-108 supports two USB 1.1 ports for serial transfers at 12 or 1.5Mbit/sec. The Universal Serial Bus (USB) is an interface allowing for connectivity to many standard PC peripherals via an external port.
Dual Ultra320 SCSI Interfaces The Ultra320 SCSI interfaces use a dual-channel Adaptec AIC-7902 SCSI controller chip. The SCSI interfaces use the SBC's internal PCI-X bus to maximize device data transfer speeds. The maximum data transfer speed is 320MB/s, and up to 15 SCSI devices per interface are supported. The interfaces comply with the SPI-3 standard and are compatible with both single-ended and Low Voltage Differential (LVD) SCSI I/O. Software drivers are available for most popular operating systems. The SBC is available without the SCSI interfaces.
Eide Ultra ATA/100 Interfaces(Dual)
Dual high-performance PCI Bus Master EIDE interfaces are capable of supporting up to two IDE disk drives each in a master/slave configuration. The interface supports Ultra ATA/100 with synchronous ATA mode transfers up to 100MB per second.
Wachdog Timer The programmable watchdog timer provides a system reset with a total range of 30ms to 60 seconds. The programmable increments of the watchdog are 30ms, 10s and 60s.
Enhanced Bi-Directional Parael Interface The parallel port interface is compatible with IBM PC/XT ® , PC/AT ® , PS/2 ™ , Enhanced Parallel Port (EPP1.7, EPP1.9) and Extended Capabilities Port (ECP) modes of operation. Both the EPP and ECP modes are IEEE 1284 compliant. The parallel port has BIOS selectable addressing.
Keyboard and PS/2 Mouse Interfaces
 The mini DIN connector located on the I/O bracket provides an external interface for a PS/2 mouse and keyboard. A "Y" adapter plugged into the mini DIN connector allows the PS/2 mouse and keyboard to share the same port. Internal PS/2 mouse and keyboard headers are also available. A self-resetting fuse protects the +5V line of the keyboard and the mouse.

Power Fail Detection The ELK-SBC6090-108 continuously monitors the incoming +5V and +3.3V power lines from the system backplane. If the +5V line drops below 4.75 volts or the +3.3V line drops below 2.97 volts, the ELK-SBC6090-108 issues a hardware-reset command. This feature helps maintain control and allows the system to automatically restart. A two-pin header is available for applications that require an external reset switch. On-board power lines are also monitored in a similar fashion.
Battery Built-in lithium battery for data retention of CMOS memory.

Humidity :5% to 90% non-condensing
An Intel ® Xeon ™ processor can consume as much as 70 Watts of power on the ELK-SBC. The ELK-SBC6090-108 cooling solution consists of an air duct assembly attached to the SBC, a high-reliability cooling fan mounted to the air duct intake, and passive heat sinks mounted to each processor. The fan maintains air movement over the processors' passive heat sinks and the air duct assembly directs the airflow over critical components. Warm air is exhausted from vents located on the SBC's I/O bracket.
Mechanical In a typical PCI/ISA backplane, the ELK-SBC6090-108's air duct design enables placement of half-size PCI cards approximately 2.3” (58.4mm) or three slots away from the SBC. Full-length cards can be placed four slots away in the backplane or approximately 3.2” (81.3mm) from the ELK-SBC6090-108
