Viglen, EMC and the ‘CE’ mark

CE Marking European standards are being harmonised across borders. If products comply to the same standards in all European countries, product exporting and importing is made simple - paving our way to a common market. If you buy a product with a 'CE' mark on it (shown below), on the box, in the manual, or on the guarantee - it complies with the currently enforced directive(s).

Introduction to EMC EMC (Electromagnetic Compatibility) is the term used to describe certain issues with RF (Radio Frequency) energy. Electrical items should be designed so they do not interfere with each other through RF emissions. E.g. If you turn on your microwave, your television shouldn't display interference if both items are CE marked to the EMC directive.

If emitted RF energy is not kept low, it can interfere with other electrical circuitry - E.g. Cars Automatic Braking Systems have been known to activate by themselves while in a strong RF field. As this has obvious repercussions ALL electrical products likely to cause RF related problems have to be 'CE' marked from 1st January 1996 onwards.

If a product conforms to the EMC directive, not only should its RF emissions be very low, but its immunity to RF energy (and other types) should be high. The apparatus has to resist many 'real world' phenomena such as static shocks and mains voltage transients.

Viglen’s Environment laboratory To gain a 'CE' mark, the Viglen computer range has had to undergo many difficult tests to ensure it is Electromagnetically Compatible. These are carried out in the in-house 'Environment lab' at Viglen Headquarters. We have made every effort to guarantee that each computer leaving our factory complies fully to the correct standards. To ensure the computer system maintains compliance throughout its functional life, it is essential you follow these guidelines.

>Install the system according to Viglen’s instructions >If you open up your Viglen: > Keep internal cabling in place as supplied. > Ensure the lid is tightly secured afterwards

> Do not remove drive bay shields unless installing a 'CE' marked peripheral in its place

> The clips or ‘bumps' around the lips of the case increase conductivity - do not remove or damage. > Do not remove the ferrite ring from the L.E.D cables. > Only use your Viglen computer with 'CE' marked peripherals

This system has been tested in accordance with European standards for use in residential and light industrial areas-this specifies a 10 meter testing radius for emissions and immunity. If you do experience any adverse affects which you think might be related to your computer, try moving it at least 10 meters away from the affected item. If you still experience problems, contact Viglen’s Technical Support department who will put you straight through to an EMC engineer - s/he will do everything possible to help. If modifications are made to your Viglen computer system, it might breach EMC regulations. Viglen take no responsibility (with regards to EMC characteristics) of equipment which has been tampered with or modified.

D865GLC Motherboard Manual

System Processor

The D865GLC motherboard supports a single Pentium 4 processor. The processor’s VID pins automatically program the voltage regulator on the motherboard to the required processor voltage. In addition, the front side bus speed is automatically selected. The motherboard currently supports processors that run internally up to

3.06GHz and have a 512 KB second-level cache running at full CPU Speed.

The processor implements MMX ™ technology and maintains full backward compatibility with the 8086, 80286, Intel386 ™, Intel486 ™, Pentium, Pentium Pro, Pentium II & Pentium III processors. The processor’s numeric coprocessor significantly increases the speed of floating-point operations and complies with ANSI/IEEE standard 754-1985.

Microprocessor Packaging

The Pentium 4 processor comes in a micro PGA 478 package that connects to the motherboard through a socket 478 connector. The package consists of:

• Processor card including the processor core and the second-level cache,

burst pipelined synchronous static RAM (BSRAM) and tag RAM.

• Thermal plate.

• Back cover.

Second Level Cache

The second-level cache is located on the die of the CPU itself. The cache includes burst pipelined synchronous static RAM (BSRAM) and tag RAM. All supported onboard memory can be cached.

Processor Upgrades

The motherboard can be upgraded with a Pentium 4 processor that runs at higher speeds.

System Memory

Main Memory

The motherboard has four DDR SDRAM Dual Inline Memory Module (DIMM) sockets. Support for up to a maximum memory size of 4GB. The BIOS automatically detects memory type, size, and speed.

The motherboard supports the following memory features:

• 2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts

• Unbuffered, single-sided or double-sided DIMMs with the following restriction:

D865GLC Motherboard Manual

o Double-sided DIMMS with x16 organisation are not supported.

• 4 GB maximum total system memory.

• Minimum total system memory: 64 MB

• Non-ECC DIMMs

• Serial Presence Detect

• DDR400, DDR333, and DDR266 SDRAM DIMMs

Table 2: Supported System Bus Frequency and Memory Speed Combinations

To use this type of DIMM… The processor’s system bus frequency must be…

DDR400 800MHz DDR333 (Note) 800 or 533MHz DDR266 800, 533 or 400MHz

Note: When using an 800MHz system bus frequency processor, DDR333 memory is clocked at

320MHz. This minimises system latencies to optimise system throughput.

Notes:

• Remove the AGP video card before installing or upgrading memory to avoid

interference with the memory retention mechanism.

• To be fully compliant with all applicable DDR SDRAM memory specifications,

the board should be populated with DIMMs that support the Serial Presence

Detect (SPD) data structure. This allows the BIOS to read the SPD data and

program the chipset to accurately configure memory settings for optimum

performance. If non-SPD memory is installed, the BIOS will attempt to

correctly configure the memory settings, but performance and reliability may

be impacted or the DIMMs may not function under the determined frequency.

Below table lists the supported DIMM configuration

Memory Configurations

The Intel 82865PE MCH component provides two features for enhancing memory throughput:

• Dual Channel memory interface. The board has two memory channels, each

with two DIMM sockets, as shown in Figure 3

• Dynamic Addressing Mode. Dynamic mode minimises overhead by reducing

memory accesses

Table 4 summarises the characteristics of Dual and Single Channel configurations with and without the use of Dynamic Mode.

SDRAM

DDR (Double Data Rate) Synchronous DRAM (SDRAM) improves memory performance through memory access that is synchronous with the memory clock. This simplifies the timing design and increases memory speed because all timing is dependent on the number of memory clock cycles.

Note: All memory components and DIMMs used with the D865GLC motherboard

must comply with the PC SDRAM specifications. These include the PC SDRAM Specification (memory component specific) and the PC Serial Presence Detect Specification.

ECC Memory

Error checking and correcting (ECC) memory detects multiple-bit errors and corrects single-bit errors. When ECC memory is installed the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the Setup program. The BIOS automatically detects if ECC memory is installed and provides the Setup option for selecting ECC mode. If any non-ECC memory is installed, the Setup option for ECC configuration does not appear and ECC operation is not available.

The following table describes the effect of using Setup to put each memory type in each supported mode. Whenever ECC mode is selected in Setup, some performance loss occurs.

Intel 865G Chipset

The Intel 865G chipset consists of the following devices:

• Intel 82865G Graphics and Memory Controller Hub (GMCH) with Accelerated

Hub Architecture (AHA) bus

• Intel 82801EB I/O Controller Hub (ICH5) with AHA bus

• Firmware Hub (FWH)

The GMCH is a centralised controller for the system bus, the memory bus, the AGP bus, and the Accelerated Hub Architecture interface. The ICH5 is a centralised controller for the board’s I/O paths. The FWH provides the nonvolatile storage of the BIOS. The component combination provides the chipset interfaces as shown in Figure 8.

Figure 8: Intel 865G Chipset Block Diagram

D865GLC Motherboard Manual

Intel 865G Graphics Subsystem

The Intel 865G chipset contains two separate, mutually exclusive graphics options. Either the Intel Extreme Graphics controller (contained within the 82865G GMCH) is used, or an AGP add-in card can be used. When an AGP add-in card is installed, the Intel Extreme Graphics controller is disabled.

D865GLC Motherboard Manual

Dynamic Video Memory Technology (DVMT)

DVMT enables enhanced graphics and memory performance through Direct AGP, and highly efficient memory utilisation. DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. Up to 64 MB of system memory can be allocated to DVMT on systems that have 256 MB or more of total system memory installed. Up to 32 MB can be allocated to DVMT on systems that have 128 MB but less than 256 MB of total installed system memory. Up to 8 MB can be allocated to DVMT when less than 128 MB of system memory is installed. DVMT returns system memory back to the operating system when the additional system memory is no longer required by the graphics subsystem.

DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup program) for compatibility with legacy applications. An example of this would be when using VGA graphics under DOS. Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions.

Note: The use of DVMT requires operating system driver support

Zone Rendering Technology (ZRT)

The Intel Extreme Graphics 2 Controller supports Zone Rendering Technology (ZRT). ZRT is a process by which the screen is divided into several zones. Each zone is completely cached and rendered on chip before being written to the frame buffer. The benefits of ZRT include the following:

• Increased memory efficiency via better localisation of data

• Increased on-chip processing speed due to decreased wait time for data

• Increased effective pixel fill rates

• Increased headroom for larger resolution and color depth

• Reduced power as a result of decreased memory bandwidth

• Reduction in depth and color bandwidth associated with conventional

rendering

Rapid Pixel and Text Rendering (RPTR)

The Rapid Pixel and Text Rendering Engine (RPTR) architecture utilises special pipelines that allow 2D and 3D operations to overlap. By providing 8X compression, the RPTR engine reduces the memory bandwidth required to read texture memory, and reduces the amount of memory required for texture storage.

A dedicated, non-blocking, multi-tier cache is provided for textures, colors, Z and vertex rendering. With single-pass, quad texture support, the drivers can submit up to four textures that pass to the graphics engine concurrently. The graphics core can switch between 2D and 3D operations without having to complete all operations of the same mode, which minimises the overhead time required in switching between modes.

D865GLC Motherboard Manual

2D Block Level Transfer (BLT) in the RPTR engine is extended to 256-bit, which supports fast blitter fill rate. This enables the blitter sequence of the same addresses to access the cache and offloads the memory bandwidth required to support blitter fill rate. Then the cache is emptied automatically when the sequence of operations are complete.

Intelligent Memory Management (IMM)

Intelligent Memory Management (IMM) technology is Intel’s unique UMA memory manager architecture, consisting of these key elements:

• Tiled memory addressing capability

• Deep display buffer implementation

• Dynamic data management scheme

The memory addressing allows address remapping in the hardware for all graphics surfaces including textures, frame buffer, Z buffer, and video surfaces. Deep display buffers and dedicated screen refreshes improve visual performance, while the dynamic data management scheme manages burst size and page closing policies for memory accesses.

IMM reduces the aggregate processor latency and allows longer in-page bursts for higher system performance. IMM also increases page coherency and improves memory efficiency in texture loads, 2D blitters, color/Z, MPEG2 motion compression, and other operations.

Video Mixing Renderer (VMR)

PC/VCR requires a TV-tuner add-in card and a third party application. PC/VCR time shifted viewing allows the user to view and digitally record video pictures on their PC. Users can view stored images while recording and by using time-shifted viewing they can pause, resume, replay, and catch up to real time. The Intel Pentium 4 processor in combination with the Intel 82865G GMCH optimises performance so that the video output is smooth without leaving any visual artifacts. Video tearing and corruption is prevented by the use of multiple buffers within the Intel Extreme Graphics 2 controller.

Bi-Cubic Filtering

Bi-cubic filtering is a new 4X4 filter that allows images to be generated more smoothly in the 3D pipeline. The bi-cubic filter can be used to improve image quality for all 3D texture engine components.

AGP Digital Display (ADD) Card Support

The GMCH routes two 12-bit multiplexed DVO ports that are each capable of driving a 165 MHz pixel clock to the AGP connector. The DVO ports can be paired for dual channel mode. In dual channel mode, the GMCH is capable of driving a 24-bit 330 MHz pixel clock. When an AGP add-in card is used, the Intel Extreme Graphics 2

D865GLC Motherboard Manual

controller is disabled and the AGP connector operates in AGP mode. When an ADD card is detected, the Intel Extreme Graphics 2 controller is enabled and the AGP connector is configured for DVO mode. DVO mode enables the DVO ports to be accessed by an ADD card. ADD cards can support up to two display devices with the following configurations:

• TV-Out and Transition Minimised Differential Signaling (TMDS)

• Low Voltage Differential Signaling (LVDS)

• Single device operating in dual channel mode

Universal 0.8V / 1.5V AGP 3.0 Connector

The AGP connector supports the following:

• 4x, 8x AGP 3.0 add-in cards with 0.8 V I/O

• 1x, 4x AGP 2.0 add-in cards with 1.5 V I/O

• AGP Digital Display (ADD) cards

AGP is a high-performance interface for graphics-intensive applications, such as 3D applications. While based on the PCI Local Bus Specification, Rev. 2.2, AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of the PCI bus related to handling large amounts of graphics data with the following features:

• Pipelined memory read and write operations that hide memory access latency

• Demultiplexing of address and data on the bus for nearly 100 percent

efficiency

Notes:

• AGP 2x operation is not supported.

• Install memory in the DIMM sockets prior to installing the AGP video card to

avoid interference with the memory retention mechanism.

• The AGP connector is keyed for Universal 0.8 V AGP 3.0 cards or 1.5 V AGP

2.0 cards only. Do not attempt to install a legacy 3.3 V AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V AGP cards.

D865GLC Motherboard Manual

USB Support

The motherboard has four USB 2.0 ports; note an optional front panel USB connector is required to use the internal USB header to provide 2 more additional ports. One USB peripheral can be connected to each port. For more than four USB devices, an external hub can be connected to either port. The motherboard fully supports the universal host controller interface (UHCI) and (EHCI) and uses UHCIand EHCI- compatible drivers. The ICH5 provides the USB controller for all ports. The port arrangement is as follows:

• Two ports are implemented with stacked back panel connectors, adjacent to

the PS/2 connectors

• Two ports are implemented with stacked back panel connectors, adjacent to

the audio connectors

• Four ports are routed to two separate front panel USB connectors

Note: USB 2.0 drivers are available for Windows 2000 Pro and Windows XP, and

currently not supported by any other operating system.

USB features include:

• Self-identifying peripherals that can be plugged in while the computer is

running.

• Automatic mapping of function to driver and configuration.

• Supports isochronous and asynchronous transfer types over the same set of

wires.

• Supports up to 127 physical devices.

• Guaranteed bandwidth and low latencies appropriate for telephony, audio,

and other applications.

• Error-handling and fault-recovery mechanisms built into the protocol.

Note: Computer systems that have an unshielded cable attached to a USB port may

not meet FCC Class B requirements, even if no device or a low-speed (sub-channel) USB device is attached to the cable. Use shielded cable that meets the requirements for high-speed (fully rated) devices.

IDE Support

The D865GLC motherboard provides four IDE interface connectors:

• Two Parallel ATA IDE connectors, which support a total of four devices (two

per connector)

• Two Serial ATA IDE connectors, which support one device per connector

D865GLC Motherboard Manual

Parallel ATA IDE Interfaces

The ICH5’s Parallel ATA IDE controller has two independent bus-mastering Parallel ATA IDE interfaces that can be independently enabled. The Parallel ATA IDE interfaces support the following modes:

• Programmed I/O (PIO): processor controls data transfer.

• 8237-style DMA: DMA offloads the processor, supporting transfer rates of up

to 16 MB/sec.

• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and

transfer rates of up to 33 MB/sec.

• ATA-66: DMA protocol on IDE bus supporting host and target throttling and

transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible.

• ATA-100: DMA protocol on IDE bus allows host and target throttling. The

ICH5’s ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.

Serial ATA Support

The ICH5’s Serial ATA controller offers two independent Serial ATA ports with a theoretical maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a maximum of two Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel.

For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI resource steering is used. Native mode is the preferred mode for configurations using the Windows XP and Windows 2000 operating systems.

LS-120 Support

LS-120 MB Diskette technology enables you to store 120MB of data on a single, 3.5” removable diskette. LS-120 technology is backward (both read and write) compatible with 1.44MB and 720KB DOS-formatted diskette and is supported by Windows 95 and Windows NT operating system.

The D865GLC board allows connection of an LS-120 compatible drive and a standard 3½” floppy drive. The LS-120 drive can be configured as a boot device before a floppy drive, if selected in the BIOS setup utility.

Note: If you connect an LS-120 drive to an IDE connector and configure it as the “A”

drive and configure a standard 3.5” floppy as “B” drive, the standard floppy must be connected to the floppy drive cable’s “A” connector (the connector at the end of the cable).

D865GLC Motherboard Manual

The BIOS setup utility can be configured to boot firstly from either the LS120 or standard 3½ “ floppy drive.

Real-Time Clock, CMOS SRAM and Battery

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.

Note: If the battery and AC power fail, custom defaults, if previously saved, will be loaded into CMOS RAM at power-on.

I/O Controller

Figure 11: Thermal Sensors

Fan Monitoring

Fan monitoring can be implemented using Intel ® Active Monitor, LANDesk* software, or third-party software. The level of monitoring and control is dependent on the hardware monitoring ASIC used with the Desktop Board.

Chassis Intrusion and Detection

The D865GLC motherboard supports a chassis security feature that detects if the chassis cover is removed. The security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion connector. When the chassis cover is removed, the mechanical switch is in the closed position.

Power Management

Power management is implemented at several levels, including:

• Software support through Advanced Configuration and Power Interface

(ACPI)

• Hardware support:

o Power connector o Fan connectors o LAN wake capabilities o Instantly Available PC technology o Resume on Ring o Wake from USB o Wake from PS/2 devices o Power Management Event signal (PME#) wake-up support

ACPI

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the D865GLC motherboard requires an operating system that provides full ACPI support. ACPI features include:

• Plug and Play (including bus and device enumeration)

D865GLC Motherboard Manual

• Power management control of individual devices, add-in boards (some add-in

boards may require an ACPI-aware driver), video displays, and hard disk drives

• Methods for achieving less than 15-watt system operation in the power-

on/standby sleeping state

• A Soft-off feature that enables the operating system to power-off the computer

• Support for multiple wake-up events

• Support for a front panel power and sleep mode switch

Table 8 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system.

System States and Power States

Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state.

Table 9 lists the power states supported by the D865GLC motherboard along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.
