Chapter 2: Board Installation

You are now ready to install your motherboard. The mounting hole pattern of the Tomcat i945GM S3095 matches the Flex ATX specification. Before continuing with installation, confirm that your chassis supports a Flex ATX motherboard.

How to install our products right… the first time

The first thing you should do is reading this user’s manual. It contains important information that will make configuration and setup much easier. Here are some precautions you should take when installing your motherboard:

(1) Ground yourself properly before removing your motherboard from the

antistatic bag. Unplug the power from your computer power supply and then touch a safely grounded object to release static charge (i.e. power supply case). For the safest conditions, TYAN recommends wearing a static safety wrist strap.

(2) Hold the motherboard by its edges and do not touch the bottom of the

board, or flex the board in any way.

(3) Avoid touching the motherboard components, IC chips, connectors,

memory modules, and leads.

(4) Place the motherboard on a grounded antistatic surface or on the

antistatic bag that the board was shipped in.

(5) Inspect the board for damage.

The following pages include details on how to install your motherboard into your chassis, as well as installing the processor, memory, disk drives and cables.

2.4 - Tips on Installing Motherboard in Chassis

Before installing your motherboard, make sure your chassis has the necessary motherboard support studs installed. These studs are usually metal and are gold in color. Usually, the chassis manufacturer will pre-install the support studs. If you are unsure of stud placement, simply lay the motherboard inside the chassis and align the screw holes of the motherboard to the studs inside the case. If there are any studs missing, you will know right away since the motherboard will not be able to be securely installed.

Some chassis’ include plastic studs instead of metal. Although the plastic studs are usable, TYAN recommends using metal studs with screws that will fasten the motherboard more securely in place.

Below is a chart detailing what the most common motherboard studs look like and how they should be installed.

2.5 - Installing the Processor, Heatsink & Fan

Your Tomcat i945GM S3095 supports the latest processor technologies from Intel. Check the TYAN website for latest processor support:

http://www.tyan.com

CPU & Heatsink Installation

The processor should be installed carefully. Make sure you are wearing an antistatic strap and handle the processor as little as possible.

Follow these instructions to install your processor

1. Place the CPU in the socket ensuring that the edge of golden arrow is aligned with the breach edge of CPU socket.

WARNING:

This new processor socket designed by Intel is easy to be damaged. The processor has to be installed very carefully to prevent the contact pins of the socket from breaking. It is strongly recommended the processor installation job to be handled by the experienced technician.

2. Use a flat screw driver to lock the CPU after installation. Refer to the picture below for the direction of locking and unlocking.

3. Install the retention module into the CPU socket from the reverse of motherboard. Tear off the stick on the retention module before installing.

4. Place the heatsink on the CPU. Use a screw driver to fix the installation of heatsink.

5. Follow the direction suggested as below to finish the installation.

Cooling Fan Installation

After you have installed the processor, the heatsink should be installed to ensure that the processor runs efficiently and does not overheat. Use the heatsink supplied for best results.

Follow these instructions to install the heatsink shown.

1. Apply some (a little will work, more doesn’t equal better performance) thermal compound to the top of the processor. Try and apply a thin, even layer over the top of the processor.

2. Align the heatsink with the four holes around the processor socket.

3. Press the heatsink down until the four screws are securely seated in the holes.

4. Use screw drive to secure the four screws.

2.6 - Installing the Memory

Before installing memory, ensure that the memory you have is compatible with the motherboard and processor. Only DDRII 400/533/667 modules are required. Check the TYAN Web site at: www.tyan.com for details of the type of memory recommended for your motherboard.

The following diagram shows common types of DDRII memory modules.

Key points to note before installing memory:

• Supports Un-buffered DDRII 400/533/667 compliant with Non-ECC memory.

• All installed memory will automatically be detected and no jumpers or settings need changing.

• The S3095 supports up to 2GB of memory.

Memory Installation Procedure

Follow these instructions to install memory modules into the S3095.

1. Press the locking levers in the direction shown in the following illustration.

2. Align the memory module with the socket. The memory module is keyed to fit only one way in the socket.

Key slot

3. Seat the module firmly into the socket by gently pressing down until it sits flush with the socket. The locking levers pop up into place.

2.7 - Attaching Drive Cables

Attaching IDE Drive Cable (S3095G3NR only)

Attaching the IDE drive cable is simple. These cables are “keyed” to only allow them to be connected in the correct manner. TYAN motherboards have two on-board IDE channels, each supporting two drives. The black

connector designates the Primary channel, while the white connector designates the Secondary channel.

Attaching IDE cables to the IDE connectors is illustrated below:

Simply plug in the BLUE END of the IDE cable into the motherboard IDE connector, and the other end(s) into the drive(s). Each standard IDE cable has three connectors, two of which are closer together. The BLUE connector that is furthest away from the other two is the end that connects to the motherboard. The other two connectors are used to connect to drives.

NOTE: Always remember to properly set the drive jumpers. If only using one device on a channel, it must be set as Master for the BIOS to detect it.

TIP: Pin 1 on the IDE cable (usually designated by a colored wire) faces the drive’s power connector.

Attaching Serial ATA Cables

The S3095 is also equipped with 2 Serial ATA (SATA) channels. Connections for these drives are also very simple.

There is no need to set Master/Slave jumpers on SATA drives.

Tyan has supplied one SATA cable. If you are in need of other cables or power adapters please contact your place of purchase.

The following pictures illustrate how to connect an SATA drive

1.SATA drive cable connection

2. SATA drive power connection

3. SATA cable motherboard connector

4. SATA drive power adapter

2.8 Installing Add-In Cards

Before installing add-in cards, it’s helpful to know if they are fully compatible with your motherboard. For this reason, we’ve provided the diagrams below, showing the slots that appear on your motherboard.

PCI Express X4 Slot

PCI Slot

Simply find the appropriate slot for your add-in card and insert the card firmly. Do not force any add-in cards into any slots if they do not seat in place. It is better to try another slot or return the faulty card rather than damaging both the motherboard and the add-in card.

2.12 - Finishing up

Congratulations on making it this far! You’re finished setting up the hardware aspect of your computer. Before closing up your chassis, make sure that all cables and wires are connected properly, especially IDE cables and most importantly, jumpers. You may have difficulty powering on your system if the motherboard jumpers are not set correctly. In the rare circumstance that you have experienced difficulty, you can find help by asking your vendor for assistance. If they are not available for assistance, please find setup information and documentation online at our website or by calling your vendor’s support line.

NOTE

Chapter 3: BIOS Setup

3.1. About the BIOS

The BIOS is the basic input/output system, the firmware on the motherboard that enables your hardware to interface with your software. The BIOS determines what a computer can do without accessing programs from a disk. The BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions. This chapter describes the various BIOS settings that can be used to configure your system.

The BIOS section of this manual is subject to change without notice and is provided for reference purposes only. The settings and configurations of the BIOS are current at the time of print and are subject to change, and therefore may not match exactly what is displayed on screen.

This section describes the BIOS setup program. The setup program lets you modify basic configuration settings. The settings are then stored in a dedicated, battery-backed memory (called NVRAM) that retains the information even when the power is turned off.

To start the BIOS setup utility:

1. Turn on or reboot your system.

2. Press <F2> during POST (F4 on remote console) to start the BIOS setup utility.

3.1.1 Setup Basics

The table below shows how to navigate in the setup program using the keyboard.

Key Function

Tab Moves from one selection to the next

Left/Right Arrow Keys Changes from one menu to the next

Up/Down Arrow Keys Moves between selections

Enter Opens highlighted section

PgUp/PgDn Keys Changes settings.

3.1.2 Getting Help

Pressing [F1] will display a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window, press [ESC] or the [F1] key again.

3.1.3 In Case of Problems

If you have trouble booting your computer after making and saving the changes with the BIOS setup program, you can restart the computer by holding the power button down until the computer shuts off (usually within 4 seconds); resetting by pressing CTRL-ALT-DEL; or clearing the CMOS. The best advice is to only alter settings that you thoroughly understand. In particular, do not change settings in the Chipset section unless you are absolutely sure of what you are doing. The Chipset defaults have been carefully chosen either by TYAN or your system manufacturer for best performance and reliability. Even a seemingly small change to the Chipset setup options may cause the system to become unstable or unusable.

3.1.4 Setup Variations

Not all systems have the same BIOS setup layout or options. While the basic look and function of the BIOS setup remains more or less the same for most systems, the appearance of your Setup screen may differ from the charts shown in this section. Each system design and chipset combination requires a custom configuration. In addition, the final appearance of the Setup program depends on the system designer. Your system designer may decide that certain items should not be available for user configuration, and remove them from the BIOS setup program.

NOTE: The following pages provide the details of BIOS menu. Please be noticed that the BIOS menu are continually changing due to the BIOS updating. The BIOS menu provided are the most updated ones when this manual is written. Please visit Tyan’s website at http://www.tyan.com for the information of BIOS updating.

MPS Version Control For OS

This feature is only applicable to multiprocessor motherboards as it specifies the version of the Multi-Processor Specification (MPS) that the motherboard will use. The MPS is a specification by which PC manufacturers design and build Intel architecture systems with two or more processors.

MPS 1.1 was the original specification. MPS version 1.4 adds extended configuration tables for improved support of multiple PCI bus configurations and greater expandability in the future. In addition, MPS 1.4 introduces support for a secondary PCI bus without requiring a PCI bridge. Select the MPS version depending on the operating system installed: select 1.1 for Win NT

3.52, and 1.4 for Win NT4.0, Win2000, and WinXP.

• 1.1

This defines the delay (in seconds) between detecting and starting IDE devices.

•0~15, the default is 1.

3.4.1 CPU Feature

Press [Enter] to access advanced features of the CPU.

Thermal Management

Thermal Management throttles the processor back as it reaches its maximum operating temperature. Throttling reduces the number of processing cycles, thereby diminishing the heat dissipation of the CPU. This cools the unit. Once the CPU has reached a safe operating temperature, thermal throttling is automatically disabled, and normal full speed processing begins again. The BIOS supports two types of thermal management.

• Thermal Monitor 1: Thermal Monitor 1 uses a highly accurate on-die temperature sensing circuit in the CPU that has the ability to act quickly upon any thermal issues (~50ns). This circuitry keeps an eye on the most taxed areas of the CPU-die at all times and will quickly act upon temperatures going over the safety limits. The thermal monitor’s control circuit, when active, lowers the CPU temperature by throttling the internal CPU clock speed. This is done with a 50% duty-cycle, which means that a 2GHz CPU will then effectively run at a 1GHz clock speed. Due to the fast response time of the thermal monitor circuit (~50ns) the CPU will only be ‘throttled’ for a very brief period. Once the CPU-die temperature is within safe operating limits again it’ll set back to the 2GHz clock speed it originally operated at.

• Thermal Monitor 2: Thermal Monitor 2 decreases or increases the CPU clock and core voltage according to the CPU load. This information is read from the five VID pins of the CPU. Accordingly, the CPU temperature is also automatically decreased, when the core voltage is decreased. This improves the CPU lifespan. The states switch is so fast that the performance decrease is insignificant.

3.4.2 Removable Device Priority

This setting controls the order that the BIOS uses to look for a removable boot device from which to load the operating system during the boot process. The removable boot sequence priority as follows:

The list you see will be depending on the devices you have.

3.4.3 Hard Disk Boot Priority

This setting controls the order that the BIOS uses to look for a hard disk from which to load the operating system during the boot process. The hard disk boot sequence priority as follows:

The list you see will be depending on the devices you have.

3.4.4 Romote Access Config

Console Redirection

This option will redirect the BIOS and POST screens to the serial port to allow remote management using a terminal server.

• Enabled

• Disabled

3.5 Advanced Chipset Features

In Advanced Chipset Features, you will be able to adjust many of the chipset special features.

DRAM Timing Selectable

This option permits you to either manually select memory timings, or allow the SPD (Serial Presence Detect) to determine the said timings automatically.

• Manual

• By SPD

Note: On all memory timing settings, lower number is more aggressive. CAS Latency Time

This setting controls the time delay (in clock cycles - CLKs) that passes before the DRAM starts to carry out a read command after receiving it. This also determines the number of CLKs for the completion of the first part of a burst transfer. In other words, the lower the latency, the faster the transaction.

• Auto

• 2

• 2.5

• 3

DRAM RAS# to CAS# Delay

This setting is the number of cycles from when a bank activate command is issued until a read or write command is accepted, that is, before the CAS becomes active.

• Auto

• 5

• 4

• 3

DRAM RAS# Precharge Time

This setting is the number of cycles needed to return data to its original location to close the bank or number of cycles to page memory before the next bank activate command can be issued.

• Auto

• 5

• 4

• 3

• 2

Precharge Delay <tRAS>

This timing controls the length of the delay between the activation and precharge commands -- basically how long after activation can the access cycle be started again. This influences row activation time that is taken into account when memory has hit the last column in a specific row, or when an entirely different memory location is requested.

Memory Hole at 15M-16M

Certain ISA cards require exclusive access to the 1MB block of memory, from the 15th to the 16th megabyte, to work properly. This BIOS feature allows you to reserve that 1MB block of memory for such cards to use.

If you enable this feature, 1MB of memory (the 15th MB) will be reserved exclusively for the ISA card's use. This effectively reduces the total amount of memory available to the operating system by 1MB. If you disable this feature, the 15th MB of RAM will not be reserved for the ISA

card's use. The full range of memory is therefore available for the operating system to use. However, if your ISA card requires the use of that memory area, it may then fail to work. Since ISA cards are a thing of the past, it is highly recommended that you disable this feature. Even if you have an ISA card that you absolutely have to use, you may not actually need to enable this feature. Most ISA cards do not need exclusive access to this memory area. Make sure that your ISA card requires this memory area before enabling this feature. You should use this BIOS feature only as a last-ditch attempt to get an ISA card to work.

• Disabled

• 378/IRQ7

• 278/IRQ5

• 3BC/IRQ7

• Disabled

Parallel Port Mode

This field allows the user to select the parallel port mode. The default value is SPP that automatically selects the correct mode to use. The other modes are explained as follows:

SPP works with all parallel port devices. However, it is the slowest transfer mode and should only be used when faster transfer modes cannot be used. There are two faster bidirectional modes available - the ECP (Extended Capabilities Port) and EPP (Enhanced Parallel Port) modes. ECP uses the DMA protocol to achieve data transfer rates of up to 2.5Mbytes/s and provides symmetric bidirectional communication. On the other hand, EPP uses existing parallel port signals to provide asymmetric bidirectional communication. For those who don't know what mode to select but at least know that their parallel port device supports bidirectional transfers, the BIOS offers the ECP+EPP mode. If you select this mode, then the parallel port device will be able to use either one of those modes. However, this should be considered as a last resort as you may be needlessly tying up an IRQ for nothing if your device does not use ECP at all. Or, the BIOS may not select the best parallel port mode for the device. If possible, set the parallel port to the transfer mode that best suits your parallel port device.

• SPP

• EPP

• ECP

• ECP + EPP

EPP Mode Select

There are two versions of the EPP transfer protocol - EPP1.7 and EPP1.9. Generally, EPP1.9 is the preferred setting because it supports the newer EPP1.9 devices and most EPP1.7 devices; and offers advantages like support for longer cables. However, because certain EPP1.7 devices cannot work properly with an EPP1.9 port, this BIOS feature was implemented to allow you to set the EPP mode to EPP1.7 when such an issue occurs. Therefore, it is recommended that you set this BIOS feature to EPP1.9. But if you have trouble connecting to your parallel port device, switch to EPP1.7.

• EPP1.7

• EPP1.9

ECP Mode Use DMA

This BIOS feature determines which DMA channel the parallel port should use when it is in ECP mode. Please note that there is no performance advantage in choosing DMA Channel 3 over DMA Channel 1 or vice versa. As long as either Channel 3 or Channel 1 is available for your parallel port to use, the parallel port will be able to function properly in ECP mode.

3.7 Power Management Setup

Options related to power management can be altered through the following:

ACPI Suspend Type

ACPI (Advanced Configuration and Power Interface) establishes industrystandard interfaces for OS-directed configuration and power management on laptops, desktops, and servers.

ACPI allows the Operating System (instead of the BIOS) to control Power Management (OSPM). The ACPI Standard defines hardware registers (which are implemented in chipset silicon), BIOS interfaces, which include configuration tables, control methods, and motherboard device enumeration and configuration; system and device power states, and the APCI thermal model. All devices in the system can communicate with each other about resource use. The operating system has the most knowledge on a running system's state, and so is in the best position to perform power management. This option specifies the method to be used hibernation. The options are as follows.

• S1 (POS) (Power On Suspend): In this method, the processor does not execute instructions but remains connected to the bus; the processor preserves the state and content of its internal registers, along with the dynamic context of the memory. Only information about devices qualified as suitable to be woken up from hibernation is kept by the processor. When a waking up event occurs, the devices that can wake up the system force all the peripherals to be relinked.

• S3 (STR) (Suspend To RAM): In this method, the processor does not execute instructions. The state and content of the processor's internal registers is stored in RAM along with the

dynamic context of the memory. Information about devices qualified as suitable to be woken up from hibernation is also stored in RAM. When a waking up event occurs, the devices that can wake up the system restore the contents of the registers of the processor from RAM and force all the peripherals to be relinked.

Run VGABIOS if S3 Resume

Selects whether to run the VGA BIOS if resumed from S3 state. This is only necessary for older VGA drivers. Select Auto, if in doubt.

• Auto

• Yes

• No Note: This option is enabled only if S3 or S1 & S3 is selected from the ACPI Suspend Type option.

3.7.1 PCI Express PM Function

PCI Express components are permitted to wakeup the system using a wakeup mechanism followed by a power management event (PME) Message. PCI Express systems may provide the optional auxiliary power supply (Vaux) needed for wakeup operation from states where the main power supplies are off. PCI Express-PM extends beyond the PME mechanism defined in conventional PCI-PM as PCI Express PME Messages include the Requestor ID of the requesting agent. These PME Messages are in-band TLPs routed from the requesting device towards the Root Complex.

PCI Express PME

This option performs the same function as Wake-Up by PCI card, but is for PCIExpress cards.

• Enabled

• Disabled

3.8 PnP/PCI Configurations

This section allows configuring PnP / PCI resources.

Reset Configuration Data

If you install a new piece of hardware or modify your computer's hardware configuration, the BIOS will automatically detect the changes and reconfigure the ESCD (Extended System Configuration Data). Therefore, there is usually no need to manually force the BIOS to reconfigure the ESCD. However, the occasion may arise where the BIOS may not be able to detect the hardware changes. A serious resource conflict may occur and the operating system may not even boot as a result. This is where the Reset Configuration Data BIOS feature comes in. This BIOS feature allows you to manually force the BIOS to clear the previously saved ESCD data and reconfigure the settings. All you need to do is enable this BIOS feature and then reboot your computer. The new ESCD should resolve the conflict and allow the operating system to load normally. Please note that the BIOS will automatically reset it to the default setting of Disabled after reconfiguring the new ESCD. So, there is no need for you to manually disable this feature after rebooting

• Enabled

• Disabled When this option is set to AUTO, the BIOS by using ESCD, controls the IRQ

and DMA assignments of all of the boot and PNP devices in the system. If you set this option to Manual, you will be able to manually assign all IRQ and DMA information.

• Auto (ESCD)

• Manual 61

PCI / VGA Palette Snoop

This option is only useful if you use an MPEG card or an add-on card that makes use of the graphics card's Feature Connector. When enabled, it corrects incorrect color reproduction by "snooping" into the graphics card's frame buffer memory and modifying (synchronizing) the information delivered from the graphics card's Feature Connector to the MPEG or add-on card. It also solves the problem of display inversion to a black screen after using the MPEG card.

• Disabled

• Enabled

***PCI Express relative items***

Maximum Payload Size

This setting defines the maximum payload size.

• 128

• 256

• 512

This controls the maximum amount of data that can be transferred in a packet. Larger payload sizes increase data throughput, but increase the time that an application must wait for data to begin being transferred.

3.8.1 IRQ Resources

This option is used to manually assign IRQ resources.

Note: This option is enabled only if the Resources Controlled By is set to manual.

Chapter 4: Diagnostics

NOTE: If you experience problems with setting up your system, always check

the following things in the following order:

Memory, Video, CPU

By checking these items, you will most likely find out what the problem might have been when setting up your system. For more information on troubleshooting, check the TYAN website at: http://www.tyan.com.

4.1 Beep Codes

Fatal errors, which halt the boot process, are communicated through two kinds of audible beeps.

•A single long beep followed by two short beeps: It indicates that a

video error has occurred and the BIOS can't initialize the video screen to display and additional info.

•A single long beep repeatedly: This indicates that a DRAM error has

occurred. The most common type of error is a memory error.

Before contacting your vendor or TYAN Technical Support, be sure that you note as much as you can about the beep code length and order that you experience. Also, be ready with information regarding add-in cards, drives and O/S to speed the support process and come to a quicker solution.

Glossary

ACPI (Advanced Configuration and Power Interface): a power management

specification that allows the operating system to control the amount of power distributed to the computer’s devices. Devices not in use can be turned off, reducing unnecessary power expenditure.

AGP (Accelerated Graphics Port): a PCI-based interface which was designed specifically for demands of 3D graphics applications. The 32-bit AGP channel directly links the graphics controller to the main memory. While the channel runs at only 66 MHz, it supports data transmission during both the rising and falling ends of the clock cycle, yielding an effective speed of 133 MHz.

ATAPI (AT Attachment Packet Interface): also known as IDE or ATA; a drive implementation that includes the disk controller on the device itself. It allows CD-ROMs and tape drives to be configured as master or slave devices, just like HDDs.

ATX: the form factor designed to replace the AT form factor. It improves on the AT design by rotating the board 90 degrees, so that the IDE connectors are closer to the drive bays, and the CPU is closer to the power supply and cooling fan. The keyboard, mouse, USB, serial, and parallel ports are built-in.

Bandwidth: refers to carrying capacity. The greater the bandwidth, the more data the bus, phone line, or other electrical path, can carry. Greater bandwidth, then, also results in greater speed.

BBS (BIOS Boot Specification): is a feature within the BIOS that creates, prioritizes, and maintains a list of all Initial Program Load (IPL) devices, and then stores that list in NVRAM. IPL devices have the ability to load and execute an OS, as well as provide the ability to return to the BIOS if the OS load process fails for some reason. At that point, the next IPL device is called upon to attempt loading of the OS.

BIOS (Basic Input/Output System): the program that resides in the ROM chip, and provides the basic instructions for controlling your computer’s hardware. Both the operating system and application software use BIOS routines to ensure compatibility.

Buffer: a portion of RAM which is used to temporarily store data, usually from an application, though it is also used when printing, and in most keyboard drivers. The CPU can manipulate data in a buffer before copying it, all at once, to a disk drive. While this improves system performance --- reading to or writing from a disk drive a single time is much faster than doing so repeatedly --- there is also the possibility of losing your data should the system crash. Information stored in a buffer is temporarily stored, not permanently saved.

Bus: a data pathway. The term is used especially to refer to the connection between the processor and system memory, and between the processor and PCI or ISA local buses.

Bus mastering: allows peripheral devices and IDEs to access the system memory without going through the CPU (similar to DMA channels).

Cache: a temporary storage area for data that will be needed often by an application. Using a cache lowers data access times, since the needed information is stored in the SRAM instead of in the slow DRAM. Note that the cache is also much smaller than your regular memory: a typical cache size is 512KB, while you may have as much as 4GB of regular memory.

Cache size: refers to the physical size of the cache onboard. This should not be confused with the cacheable area, which is the total amount of memory which can be scanned by the system in search of data to put into the cache. A typical setup would be a cache size of 512KB, and a cacheable area of 512MB. In this case, up to 512KB of the main memory onboard is capable of being cached. However, only 512KB of this memory will be in the cache at any given moment. Any main memory above 512MB could never be cached.

Closed and open jumpers: jumpers and jumper pins are active when they are “on” or “closed”, and inactive when they are “off” or “open”.

CMOS (Complementary Metal-Oxide Semiconductors): chips that hold the basic startup information for the BIOS.

COM port: another name for the serial port, which is called as such because it transmits the eight bits of a byte of data along one wire, and receives data on another single wire (that is, the data is transmitted in serial form, one bit after another). Parallel ports transmit the bits of a byte on eight different wires at the same time (that is, in parallel form, eight bits at the same time).

DDR (Double Data Rate): is a technology designed to double the clock speed of the memory. It activates output on both the rising and falling edge of the system clock rather than on just the rising edge, potentially doubling output.

DIMM (Dual In-line Memory Module): faster and more capacious form of RAM than SIMMs, and do not need to be installed in pairs.

DIMM bank: sometimes called DIMM sockets, because the physical slot and the logical unit are the same. That is, one DIMM module fits into one DIMM socket, which is capable of acting as a memory bank.

DMA (Direct Memory Access): channels that are similar to IRQs. DMA channels allow hardware devices (like soundcards or keyboards) to access the main memory without involving the CPU. This frees up CPU resources for other

tasks. As with IRQs, it is vital that you do not double up devices on a single line. Plug-n-Play devices will take care of this for you.

Doze mode: in this mode, only the CPU’s speed is slowed. DRAM (Dynamic RAM): widely available, very affordable form of RAM which has the unfortunate tendency to lose data if it is not recharged regularly (every few milliseconds). This refresh requirement makes DRAM three to ten times slower than non-recharged RAM such as SRAM.

ECC (Error Correction Code or Error Checking and Correcting): allows data to be checked for errors during run-time. Errors can subsequently be corrected at the same time that they’re found.

EEPROM (Electrically Erasable Programmable ROM): also called Flash BIOS, is a ROM chip which can, unlike normal ROM, be updated. This allows you to keep up with changes in the BIOS programs without having to buy a new chip. TYAN’s BIOS updates can be found at http://www.tyan.com

EMRL: Embedded RAID Logic. An Adaptec specific RAID technology. ESCD (Extended System Configuration Data): a format for storing

information about Plug-n-Play devices in the system BIOS. This information helps properly configure the system each time it boots.

Fault-tolerance: a term describing a system where one component can quickly be replaced without causing a loss of service, such as in a RAID system.

Firmware: low-level software that controls the system hardware. Form factor: an industry term for the size, shape, power supply type, and

external connector type of the Personal Computer Board (PCB) or motherboard. The standard form factors are the AT and ATX, although TYAN also makes some Baby-AT and ATX Footprint boards.

Global timer: onboard hardware timer, such as the Real-Time Clock (RTC). Handshaking: a process where two devices initiate communications. One

device, typically the server, sends a message to another device, typically a client, in order to request establishment of a communications channel. The two devices will then exchange messages back and forth in order to settle on a communications protocol.

HDD: stands for Hard Disk Drive, a type of fixed drive. H-SYNC: controls the horizontal synchronization/properties of the monitor. IC (Integrated Circuit): the formal name for the computer chip.

IDE (Integrated Device/Drive Electronics): a simple, self-contained HDD interface. It can handle drives up to 8.4 GB in size. Almost all IDEs sold now are in fact Enhanced IDEs (EIDEs), with maximum capacity determined by the hardware controller.

IDE INT (IDE Interrupt): a hardware interrupt signal that goes to the IDE. I/O (Input/Output): the connection between your computer and another piece

of hardware (mouse, keyboard, etc.) Initial Program Load (IPL): a feature built into BBS-compliant devices,

describing those devices as capable of loading and executing an OS, as well as being able to provide control back to the BIOS if the loading attempt fails.

IPL: see Initial Program Load. IRQ (Interrupt Request): an electronic request that runs from a hardware

device to the CPU. The interrupt controller assigns priorities to incoming requests and delivers them to the CPU. It is important that there is only one device hooked up to each IRQ line; doubling up devices on IRQ lines can lock up your system. Plug-n-Play operating systems can take care of these details for you.

ISA (Industry Standard Architecture): a slower 8- or 16-bit bus (data pathway).

Latency: the amount of time that one part of a system spends waiting for another part to catch up. This is most common when the system sends data out to a peripheral device, and it waiting for the peripheral to send some data back (peripherals tend to be slower than onboard system components).

Mirroring: see RAID. NVRAM: ROM and EEPROM are both examples of Non-Volatile RAM, memory

that holds its data without power. DRAM, in contrast, is volatile. OEMs (Original Equipment Manufacturers): Compaq or IBM package other

companies’ motherboards and hardware inside their case and sell them. Parallel port: transmits the bits of a byte on eight different wires at the same

time (that is, in parallel form, eight bits at the same time). PCI (Peripheral Component Interconnect): a 32 or 64-bit local bus (data

pathway) which is faster than the ISA bus. Local buses are those which operate within a single system (as opposed to a network bus, which connects multiple systems).

PCI PIO (PCI Programmable Input/Output) modes: the data transfer modes used by IDE drives. These modes use the CPU for data transfer (in contrast, DMA channels do not). PCI refers to the type of bus used by these modes to communicate with the CPU. PCI-to-PCI bridge: allows you to connect multiple PCI devices onto one PCI slot.

Pipeline burst SRAM: a type of RAM that can maintain it’s data as long as power is provided to the memory chips. In this configuration, SRAM requests are pipelined, which means that larger packets of data are sent to the memory at one time, and acted upon quickly. This type of SRAM operates at bus speeds higher than 66MHz.

Pipelining: improves system performance by allowing the CPU to begin executing a second instruction before the first is completed. A pipeline can be likened to an assembly line, with a given part of the pipeline repeatedly executing a set part of an operation on a series of instructions.

PM timers (Power Management timers): software timers that count down the number of seconds or minutes until the system times out and enters sleep, suspend, or doze mode.

PnP (Plug-n-Play): a design standard that has become ascendant in the industry. Plug-n-Play devices require little set-up to use. Novice end users can simply plug them into a computer that is running on a Plug-n-Play aware operating system (such as Windows 98), and go to work. Devices and operating systems that are not Plug-n-Play require you to reconfigure your system each time you add or change any part of your hardware.

PXE (Preboot Execution Environment): one of four components that together make up the Wired for Management 2.0 baseline specification. PXE was designed to define a standard set of preboot protocol services within a client, towards the goal of allowing networked-based booting to boot using industry standard protocols.

RAID (Redundant Array of Independent Disks): a way for the same data to be stored in different places on many hard drives. By using this method, the data is stored redundantly, also the multiple hard drives will appear as a single drive to the operating system. RAID level 0 is known as striping, where data is striped (or overlapped) across multiple hard drives, but offers no fault-tolerance. RAID level 1 is known as mirroring, which stores the data within at least two hard drives, but does not stripe. RAID level 1 also allows for faster access time and fault-tolerance, since either hard drive can be read at the same time. RAID level 0+1 is both striping and mirroring, providing fault-tolerance, striping, and faster access all at the same time.

RAIDIOS: stands for RAID I/O Steering, a type of RAID technology from Intel. RAIDIOS is a specification used to enable an embedded I/O controller, embedded on the motherboard, to be used as just an I/O controller or to be the I/O component of a hardware RAID subsystem. The RAIDIOS circuit allows an I/O Processor (either embedded on the motherboard or on an add-in card) to configure the I/O controller and service the I/O controller’s interrupts. The I/O controller and the I/O Processor together are two of the primary components of a hardware RAID subsystem.

RAM (Random Access Memory): technically refers to a type of memory where any byte can be accessed without touching the adjacent data, is often used to refer to the system’s main memory. This memory is available to any program running on the computer.

ROM (Read-Only Memory): a storage chip which contains the BIOS; the basic instructions required to boot the computer and start up the operating system.

SATA (Serial ATA): is an evolutionary replacement for the Parallel ATA physical storage interface. Serial ATA is a drop-in solution in that it is compatible with today’s software and operating systems. It will provide for systems which are easier to design, with cables that are simpler to route and install, smaller cable connectors, and lower voltage requirements.

SDRAM (Synchronous Dynamic RAM): called as such because it can keep two sets of memory addresses open simultaneously. By transferring data alternately from one set of addresses and then the other, SDRAM cuts down on the delays associated with non-synchronous RAM, which must close one address bank before opening the next.

Serial port: called as such because it transmits the eight bits of a byte of data along one wire, and receives data on another single wire (that is, the data is transmitted in serial form, one bit after another).

SCSI Interrupt Steering Logic (SISL): Architecture that allows a RAID controller, such as AcceleRAID 150, 200 or 250, to implement RAID on a system board-embedded SCSI bus or a set of SCSI busses. SISL: SCSI Interrupt Steering Logic ( LSI ) (only on LSI SCSI boards)

SIMM (Single In-line Memory Module): formally the most common form of RAM for motherboards. They must be installed in pairs, and do not have the carrying capacity or the speed of DIMM modules.

Sleep/Suspend mode: in this mode, all devices except the CPU shut down. SRAM (Static RAM): unlike DRAM, this type of RAM does not need to be

refreshed in order to prevent data loss. Thus, it is faster and more expensive.

SSI (Server System Infrastructure): an industry initiative intended to provide ready-to-use design specifications for common server hardware elements (chassis, power supplies, and racks) to promote and support server industry growth.

Standby mode: in this mode, the video and hard drives shut down; all other devices continue to operate normally.

Striping: see RAID UltraDMA-33/66/100: a fast version of the old DMA channel. UltraDMA is also

called UltraATA. Without proper UltraDMA controller, your system cannot take advantage of higher data transfer rates of the new UltraDMA/UltraATA hard drives.

USB (Universal Serial Bus): a versatile port. This one port type can function as a serial, parallel, mouse, keyboard or joystick port. It is fast enough to support video transfer, and is capable of supporting up to 127 daisy-chained peripheral devices.

VGA (Video Graphics Array): the PC video display standard V-SYNC: controls the vertical scanning properties of the monitor.

ZCR: Zero Channel RAID. PCI card that allows a RAID card to use the

onboard SCSI chip, thus lowering cost of RAID solution ZIF Socket (Zero Insertion Force socket): these sockets make it possible to

insert CPUs without damaging the sensitive CPU pins. The CPU is lightly placed in an open ZIF socket, and a lever is pulled down. This shift the processor over and down, guiding into the board and locking it into place.

NOTE

Technical Support

If a problem arises with your system, you should turn to your dealer for help first. Your system has most likely been configured by them, and they should have the best idea of what hardware and software your system contains. Furthermore, if you purchased your system from a dealer near you, you can bring your system to them to have it serviced instead of attempting to do so yourself (which can have expensive consequences).
