Chapter 2: Board Installation

2.1 Installation

Once you’ve checked th at everything is ins ide the box (see p. 4 for details), you will then be ready to install your mothe rboard . The m ounti ng ho le patt ern o f the m other board match es t he ATX board specif ications, so your chassis must be capable of suppor ting an Extended ATX board (check the mo therbo ard dimensions provided on p. 8).

2.2 How to install our products right.. the first time.

Question: what’s the first thing I should do?

The first thing you should do is read the user’s manual. It contains important information which will make configuration and setup much easier, as well as provide information on device installation and component setup. By reading through the manual completely before installing your motherboard, you will have a complete overview on the installation.

2.3 Here are some safety tips:

(1) Ground yourself properly before removing your motherboard from the antistatic bag. Unplug the power from your computer power supply and touch any metal part on the computer case. (You might also want to wear a grounded wrist strap.) (2) Hold the motherboard by its edges and do not touch the bottom of the board. (3) Avoid touching motherboard components, IC chips, connectors, and leads. (4) Avoid touching pins of memory modules and chips. (5) Place motherboard on a grounded antistatic surface or on the antistatic bag.

Having reviewed the precautions above, the next step is to take the motherboard out of the cardboard box and static bag, hold it by its edges, and place it on a grounded antistatic surface (such as the bag it came in), component side up. Then, inspect the board for damage.

NOTE: DO NOT APPLY POWER T O THE BOARD IF IT HAS BEEN DAMAGED!

Press down on any of the socketed ICs if it appears that they are not properly seated (the board should still be on an antistatic mat or on top of the bag it came in). Do not touch the bottom of the board. Remember, don’t take any electronic device out of its protective bag until you are ready to actually start installing it into the computer case (e.g. setting jumpers, etc.) If you do not ground yourself, you risk zapping the motherboard or adapter card. Subsequent problems may not arise immediately because electrostatic discharge, unlike physical damage, causes the device to fail over time.

Thunder K7 S2462

2.4 Quick References for Jumpers

In this manual, the term “close d” and “on” are used wh en referring to jumpers (or jumper pins) that are active; “open” and “off” a re u s ed whe n re fer ring to j u mp ers (or j um per pin s) that are inactive. See Figure

2.0a and Figure 2.0c for examples of “on” and “off” pins and jumpers.

Jumpers and pins are connec ted by slipping the plastic jum per connector over the top of tw o adjacent jumper pins (indica ted b y 1-2 or 2-3 ). Th e met al r od insid e the plast ic shell bridg es the gap b etween the two pins, completing the circ uit. See Figure 2.0b and Figure 2.0d for more examples of 3-pin jumper connections. NOTE: The small number “1” indicates pin 1.

The tables and maps on the following pages will help you set the jumpers for CPU speed, infrared, and external connector pin assignments, among others. The miniature motherboard maps will help you locate the jumpers on your board. Full page maps of the motherboard can be found on the next two pages.

2.6-N. Soft Power Connector

The soft power c onnector is pa rt of jump er block J12 (pins 13 and 15) . This board uses the ch ipset for power management, including turning on and off the system. If the power butto n function option in the BIOS Power Management m enu is set to “On/Off” (wh ich is the d efault), pressing th e power bu tton once after the BIOS has booted up will turn the system on and off. If the power button function is set to Suspend, pressing the power button once will wake up the system or send it to Suspend mode. In this case, you cannot turn the syste m o ff unless you shu t d own thr oug h t he Windo ws op er ating syst em or you ho ld the power button down for four seconds (BIOS-dependent feature).

2.6-O. Hardware Reset Switch Connector Installation

The reset switch on your chassis case provides you with the Hardware Reset function, which is the same as power on/off, except that the system will immediately execute a cold start afte r the reset button is pushed. The reset switch needs to be connected to jumper block J12 (pins 7 and 9).

2.6-P. Flash Utility

You can upgrade the BIOS of this motherboard by using the Flash Utility (see p. 46). Check the Tyan website for more details: http://www.tyan.com

2.7 Mounting the Motherboard into the Chassis

Your chassis may include mounting hardware. If mounting hardware w as included, yo u can use the fo llowing examples to help you in installing your motherboard into the chassis.

The chassis may have com e wit h th e stud s int egr ate d in to t he cha ssis wa ll, so in t hose ca ses you wou ld only need to use scre ws (p ossibly i nclude d with you r chass is) to instal l the m other board . See the ex amples (Figure 2.0, shown below) for more details.

If the chassis includes mounting hardware without the studs pre-installed, then you will need to install the motherboard using the mounting hardware as shown in t he examples below. Remember not to overtighten any of the sc rews, or you might risk breaking i nternal tr aces in the su rroundi ng area, or damage the motherboard in some other way.

Other examples of how to install your motherboard using other hardware (that may or may not have been included with your chassis) are shown below.

2.8 Installing Memory

Please keep in m ind t hat although some m em or y m od ules may appear to b e high-quality, they may contain inferior or subs tandard parts . The type of m emory you choo se to install sho uld be checked ag ainst the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com

Here are some details of memory installation for this board:

At least one REGISTERED DDR DIMM** must be installed for the system to POST.

Supports 128MB, 256MB, 512MB*, & 1024MB* PC1600/2100 REGISTERED DDR ONLY**.

All installed memory will be automatically detected, so there is no need to set any jumpers.

The motherboard supports up to 4GB* of PC1600/2100 REGISTERED DDR memory ONLY**.

Memory Installation Procedure***

Step

* Not validated at time of print, please check Tyan website for memory compatibility information: http://www.tyan.com

** This board supports DDR memory ONLY. Please check that you are using the correct type of memory. *** Manufacturer suggestion: start installation with DIMM (bank) 1 (see p.22)

Line your module up so that the pins fit into the socket. There is only one way your DIMM can

fit properly. Make sure that the short row of pins is lined up with the short gap in the DIMM socket, just as the long row of pins should line up with the long gap in the DIMM socket.

short row of pins long row of pins

Insert the DIMM by pushin g the module into th e socket with even force. Do not insert one

end and then the other: install the whole module at once or you might bend the DIMM pins. Make sure the DIMM is securely seated.

http://www.tyan.com

Step

Lock the DIMM into place by pu shing the clips back on either end of th e socket onto the

notches in the ends of the DIMM (see pictures below for details).

Removing a DIMM

2.9 Installing the CPU and Cooling Fan

Certain AMD* processors up to 1+GHz can be used on this board. For more information on CPU compatibility, check Tyan’s website at: http://www.tyan.com.

When installing your CPU, remember the following:

The CPU is a sensitive electronic component and can easily be damaged by static electricity

Do not touch the CPU pins with your fingers

You should be able to insert the CPU into the socket with virtually no force

Do not press down hard on the CPU as you might bend or break pins, or otherwise damage the CPU

The CPU voltage will automatically be detected by the motherboard, so there is no need to set any jumpers or BIOS setting.

Installing the AMD* CPU

Before installing the CPU, check it for any visible damage. Make sure none of the pins ar e bent or missing. Be sure where Pin 1 is on both the CPU and the socket. The following steps each have a corresponding picture next to it to help guide you through the installation.

Step

* At time of printing, CPU name was not confirmed. Check http://www.tyan.com for updates

Carefully lift the arm of the ZIF socket until it is at a 90 degree angle

pointing away from the motherboard. Be very careful not to damage any components that might be next to the socket.

There are two beveled corners on the CPU, which will match the

two angled corners on the socket. Carefully install the CPU by lining both Pin 1 on the CPU an d Pin 1 on the socket, ma king sure the pins actually fit into the socket. Do not force the CPU into the socket: check the pin alignment of CPU pins to socket holes.

Push down lightly on the CPU while lowering the arm on the socket

to secure the CPU (se e right). A squeaking noise may be he ard while lowering the arm, or the socket may make a ‘click’ noise when the arm is locked into position: these noises are normal.

Installing the Cooling Fan(s)

After a CPU has been installed, you will need to install the p roper cool ing device * for the CPU. Th is device, a heatsink/fan com bination , can be purc hased at ma ny compute r retail store s. Installat ion of the cooling device* may vary d epend ing on the fan m anufa cturer’s design. You should also take space into consideration when install a cooling device*: make sure the cooling device is not too big, or else you may end up damaging components around the CPU socket.

Tyan highly recommends t hat you use some type of thermal compound (avai lable from many co mput er ret ail stores), between the CP U and heat sink, to maximize distribution of heat away from the CPU. Please use extra caution when installing any type of clamp-style fan, or else damage may occur to the CPU socket, and/or the CPU itself. See the picture to the right for an exa mple of how to connect the cooling fan’s power supply. Another diagram has also been provided below, to aid in CPU fan installation onto the socket. Check with your cooling device* vendor for more details about installation.

2.10 Connecting IDE and Floppy Drives

A variety of IDE a nd ATAPI-compliant devices can be installed on this mother board, such as h ard disk drives (HDDs) and CD-ROMs.

Please keep in mind that on this mothe rboard, the primary IDE connec tor is BLACK, and the secondary IDE connector is WHITE. See the picture to the rightfor an example of the IDE cable properly connected to the motherboard, with the BLUE end of the IDE cable installed on the motherboard .

Pin 1 on the IDE cable is usually denoted by a red or colored stripe down o ne side of the cable. That side o f the cable must match Pin 1 on the motherboard’s IDE connector. There will also be a key pin on the cable that matches with a notch in the ID E connector, to ensure proper installation. Consult the documentation that came with your IDE/ATAPI device, or contact the device’s manufacturer for more details on installation.

Please note that UltraDMA-100/66 IDE HDDs require a special 80-wire cable which has additional grounding wires. This cable has been incl uded with this motherboard for your convenience. The UltraDMA-100/66 cable is backwards compatible with UltraDMA-33 and legacy IDE HDDs.

Thunder K7 S2462

May be a Master/Slave configuration problem, bad IDE cable, or BIOS mis-configuration. Consult the HDD documentation or contact your HDD vendor.

May be a bad cable or lack of power going to the drive. Check the cables for damage and bad connections.

Usually means the cable was installed backwards.

Bad IDE cable or defective drives/motherboard. Try another HDD, or contact your HDD vendor.

Check power cables and cabling. May be a bad power supply or IDE drive problem.

Connecting Floppy Drives

See the pictu re be low for an example of a fl oppy cab le. Most of the current floppy drives on the ma rket require that the cable be instal led with th e colored str ipe positi oned ne xt to the power connector. In most cases, there will be a key pin on the cable which will force a proper connection of the cable.

The first floppy drive (someti mes denot ed as A:) is usually attached to the end of the cable with the twist in it. Drive B: is usually conn ected to the second or thi rd connector in the cable (the se cond or third connector a fter you install Drive A:). Refer to your floppy drive’s installation instructions (if available), or contact your dealer if you are unsure about how to attach the floppy drive(s). Remember, you can only have 2 floppy drives connected at any given time.

2.11 Installing Add-on Cards

There are a few rules you need to follow when installing add-on cards. In order to assure proper operation and a quick installation, adhere to the following guidelines:

If you are going to install a PCI-bus interface card on your system, be aware that any one of the five PCI slots can support a Master or Slave device.

NEVER force a card into a slot. If it doesn’t fit, look at the socket on the motherboard to make

sure there are no wires or other obstructions to the slot.

NEVER plug an ISA card into a PCI slot. You will void your warranty and damage your system

board if you do this.

When plugging the card in, especially when installing long cards, try to push the entire card in at one time. Don’t force one end of the card into the socket first and then the other, or a rocking motion between the card and the slot might occur, and could damage the pins within the socket.

Make sure the cards are seated securely into their slots.

Before turning on the system, make sure no cards are touching.

Check the PCI device specifications with the PCI slot specifications (p.5) BEFORE installing!

When installing the add-on cards, make sure the cards are installed with even force; do not insert one end and then the other. See the before (Figure 2.1a) and after (Figure 2.1b) example in sta l la t i on i ma g es below for details.

Check orientation of card when installing

About the AGP Pro slot

If you are planning to install an AGP Pro-compliant card, a small plastic retention piece must be removed from the AGP Pro slot before the card can be installed.

1 2

Figure 2.2a Figure 2.2b

First, make sure the card you’re installing is an AGP Pro-compliant card. Next, locate the small plastic retention piece in the AGP Pro slot (Figure 2.2a, above), and use a tool with a small hard tip (such as a pen) to remove the retention piece (Figure 2.2b, above). Tyan recommends you save this piece for

future use (e.g. in case a regular AGP card is installed later on).

T o further ensure that the AGP card will not rock back and forth, make sure that the metal endpiece of the AGP card is flush with the motherboard edge.

Only remove the small plastic retention piece if you are going to install an AGP Pro-compliant card. Installing a regular AGP card without the retention piece can cause the card to rock back and forth, possibly dam ag ing the card and /or moth er-

2.15 Frequently Asked Questions (FAQ)

Q: My system sometimes becomes unstable. How should I check the system?

A: The first thing to do is to check and see if you have any device conflicts related to the IRQ, or DMA. If you are using Microsoft Windows, the Control Panel is a good place to start investigating the conflict. Please consult your operating system documentation for details. Secondly, slowing down the memory timing in the BIOS’ chipset setup section might help the situation as well. Many memory modules are not suitable for high performance systems and might be the main source of your problem. Also check to make sure you are using an APPROVED power supply, such as the Delta DSP465AB-A or the NMB

SD025A460WSW. Lastly, make sure the motherboard is receiving adequete cooling.

Q: I have a question about memory compatibility; what memory will work on my motherboard? A: Memory compatibility information can be found on Tyan’s website at: http://www.tyan.com

Q: Where can I get additional accessories for my Tyan motherboard?*

A: You can purchase additional accessories such as USB cables*, as well as other Tyan-approved accessories at the Tyan Computer Online Store: http://www.etyan.com

Q: Where do I get pinout information for my motherboard? A: Pinouts of certain headers are available on the Tyan website: http://www.tyan.com

Q: My motherboard is dead, how do I return it?

A: Contact the place of purchase or your distributor for assistance to return the motherboard for service. RMA issues will not be handled via e-mail by Tyan Tech Support. Please refer to the URL link here for more details: http://www.tyan.com/support/html/rma_faq.html

Chapter 3: BIOS Setup

Introduction to the BIOS setup

The BIOS is the basic inpu t/output syst em, requ ired by the computer to perform functions suc h as CPU and hard drive supp ort . T his ch apt er des cri be s differe nt settings for the BIOS that can be use d to co nfi gure your system.

The BIOS section of the manual is subject to change without notice and is provided here for reference purposes o nly. The settings an d conf iguration s of the BIOS are current at the t ime of pr int, and therefore they may not be exactly the same as that displayed on your screen.

This manual describes the BIOS setup prog ram. The setup pro gram lets y ou modify b asic conf iguration settings. The settings are the n sto red in a de dicated battery-backed memory, called NVRAM, that retains the information when the power is turned off.

The BIOS in your motherboard is a customized version of an industry-standard BIOS for IBM PC AT-compatible personal comput ers. It supports Intel x86 and compatible processo rs. The BIOS provides cri tical low-level support for the system central processing, memory, and I/O subsystems.

The BIOS has been customized by add ing i m por tan t, but non- stan da rd, featu re s such as vir us and password protection, power management, a nd detailed fine- tuning of the ch ipset controlling the s ystem. The rest of this manual is intende d to guide you through the process of configuring y our system using this BIOS setup program.

Starting Setup

The BIOS is immediately a cti vat ed wh en yo u fi rs t tur n on the co mp ute r. The BIOS reads s ystem con figuration information in CM OS RAM and be gins the pro cess of checking out the system and configur ing it through the Power-On Self Test (POST).

When these preliminaries are finishe d, the B IOS seeks a n operat ing system on one of t he data storage devices (HDD, floppy drive, etc.) If one is found, the BIOS will launch that operatin g system and hand control of system operations to it. You can start the setup program by pressing the [F2] key while the system is booting up.

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

4.1 Beep Codes

Fatal errors, which halt the boot process, are communicated through a series or audible beeps. For example, if the Phoenix BIOS POST can initialize the video but an error occurs, an error message will be displayed. If it cannot display video, it will convey a series of beeps.

If you hear one long beep followed by two short beeps, then a video problem has probably occured and the BIOS is having difficulty initializing the video display. Any other beep sequences that may or may not occur are probably due to memory problems.

Appendix I: SCSI Installation and LAN Information

Introduction

The Adaptec 7899W enables you to connect up to 30 SCSI devices—such as very large arrays of highperformance HDDs, external storage subsystems, clustered configurations, Ultra160 hard disk drives, scanners, and CD-ROM drives.

The Adaptec 7899W can support up to two independent SCSI channels, each with a maximum throughput of 160 MBytes/sec. SCSI Channel A (marked* either as “CH 1” or “CH A” on the board) has one internal connector. SCSI Channel B (marked* either as “CH 2” or “CH B” on the board) has one internal connector.

You can connect Ultra160 and Ultra2 SCSI devices to the 68-pin Low Voltage Differential/Single-Ended (LVD/SE) connectors on both SCSI channels. Or you can operate the newer Ultra160 and Ultra2 devices at their maximum speed on Channel B while at the same time using legacy SCSI devices on Channel A.

This installation guide explains how to

• Set up SCSI devices

• Connect SCSI devices

Support for Older SCSI Devices

We recommend that if you have single-ended Ultra SCSI and earlier SCSI devices you connect them to Channel A of the Adaptec 7899W SCSI and that you connect newer Ultra2 and Ultra160 SCSI devices to Channel B. This allows the Adaptec 7899W to support newer Ultra160 and Ultra2 SCSI devices at speeds up to 160 MBytes/sec while at the same time supporting Ultra (legacy) devices at speeds up to 40 MBytes/sec. It also allows you to use longer cable lengths for the newer SCSI devices.

If you connect Wide Ultra/Ultra SCSI devices to the same SCSI channel as Ultra160 and Ultra2 SCS I devices, the data transfer rate for the Ultra160 and

NOTE:

Setting up SCSI devices

There are several things you may need to do to your SCSI devices before you connect them to the Adaptec 7899W SCSI:

• Check the SCSI IDs

• Set the termination

• Connect the power cables

* subject to change without notice

Ultra2 SCSI devices will drop to Ultra SCSI per formance leve ls. To achieve maximum data transfer rate s for the ne wer SCSI de vices, be sure to conne ct them on their own SCSI channel.

Thunder K7 S2462

Since setup can vary from device to device, always refer to the device’s documentation for specific instructions. Below are some guidelines for setting SCSI IDs and termination on your devices.

Check the SCSI IDs

The Adaptec 7899W and each device you connect to it must have a unique SCSI ID number ranging from 0 to 15 on each channel. No two devices on the same SCSI channel can have the same SCSI ID.

The Adaptec 7899W is preset to ID 7 for each channel and should not be changed. If you boot from a SCSI hard disk, make sure the hard disk SCSI ID is set to 0. (Most SCSI hard disks are preset to SCSI ID 0 at the factory.) The SCSI IDs for internal devices are usually set with jumpers; SCSI IDs for external devices are usually set with a switch on the back of the device.

Terminate the Ends

To ensure reliable communication on the SCSI bus, the device at the end of each cable, or the end of the cable itself, must have a terminator installed (or enabled). Terminators must be removed, or termination must be disabled, on devices between the ends of each cable.

When connecting Ultra160 or Ultra2 SCSI devices, the SCSI bus must be terminated either on the end of the cable (w ith a pe rma ne nt ter mi na tor ) or with a separate terminating connector. Ultra SCSI and earlier single-ended devices can

NOTE:

terminate the bus directly from th e device. If y ou use an Ultra SC SI termi nator on an LVD Ultra160 and Ultra2 SCSI bus you will force the bus to Single-ended mode, limiting the spee d and cable distance. For this reason b e sure that you have the necessary Ultra160 or Ultra2 cable or terminator befo re installing the Ultra160 SCSI devices.

Connecting SCSI Devices

You can connect a total of 30 SCSI devices to the Adaptec 7899W,with up to 15 devices on each SCSI channel. Before connecting devices, be sure to review Setting up SCSI Devices on p. 47.

Connecting Internal Ultra160 and Ultra2 Devices

A special 68-pin internal LVD cable is needed to connect internal Ultra160 or Ultra2 SCSI devices. If your cables are not marked, you can identify most LVD cables as having twisted pairs of the flat ribbon cable between the device connectors. Some cables are laminated so that they lay flat. Internal LVD cables usually have a terminator built into the end of the cable.

The Adaptec 7899W has two separate Ultra160 SCSI channels, as shown on the board map on p. 11. Each channel has an internal LVD/SE connector to which you can connect internal SCSI devices. Follow these steps to connect your internal Ultra160 and Ultra2 devices:

http://www.tyan.com

NOTE:

We recommend that yo u k eep your Ultra160 and Ul tr a2 SC SI d evi ce s o n a se parate SCSI channel from your Ultra SCSI devices. This allows the newer Ultra160 and Ultra2 SCSI devices to transfer data at their maximum speed.

Step

Locate a 68-pin internal LVD SCSI cable, which may have either twisted wires or flat wires,

as shown here.

Terminated end

Plug the non-terminated end of the cable(s) to the LVD/SE SCSI connector(s) (shown below).

Plug the internal Ultra160 and Ultra2 SCSI devices to the other cable connectors, starting

with the co nnector at the terminated end of the cable (note: example installation below may not identically represent installation).

Non-terminated end

Terminator device

Internal Ultra160 SCSI peripherals come from the factory without termination. Proper

NOTE:

termination is pro vided by the built-in termina tor at the end of the Ult ra160 internal SCSI cable.

Thunder K7 S2462

Step

Connecting Wide SCSI Devices

You can connect Wide SCSI devices to the internal LVD/SE connectors. If you do this, we recommend that you connect them to the SCSI Channel A LVD/SE connector and that you connect all Ultra160 and Ultra2 devices to the SCSI Channel B connector. Follow these steps to connect Wide SCSI devices:

Connect a power cable from your computer’s in ternal power supply to each internal SCSI

device.

Step

Locate a 68-pin internal Wide SCSI cable.

Plug one end of the cable to one of the SCSI connectors.

Plug the other end of the cable to a terminated Ultra/Fast Wide SCSI device.

If you have other Ultra/Fast Wide SCSI devices, attach them to the connectors between the

two ends of the cable. Be sure these other devices are unterminated.

Step

Connect a power cable from your computer’s in ternal power supply to each internal device.

http://www.tyan.com

More information about termination

The last SCSI device on the end of each SCSI bus cable must be terminated, and termination must be disabled for all other devices in the middle of the cables. Ultra160 and Ultra2 SCSI devices are automatically un-terminated, but Ultra SCSI and Fast/Wide SCSI devices do have termination that you must check. For more information, refer to the documentation for each SCSI device. If you are using external Ultra2 or Ultra160 devices, be sure to use an LVD terminator to terminate the last device in the chain. If you use a single-ended, active terminator (sometimes called an Ultra terminator) the SCSI devices will not operate at their maximum speed.

If you have any problems while setting up SCSI devices, check the following items first:

• Are all SCSI devices powered on?

• Are all SCSI cables and power cables properly connected?

• Does each device on each SCSI bus have a unique SCSI ID?

• Does the total SCSI cable length exceed the maximum allowable length? (See table below.)

• Is the SCSI bus properly terminated?

If you are still unable to resolve a problem, contact your vendor for help.

Configuring the Adaptec 7899W SCSI with SCSISelect

SCSISelect enables you to change SCSI settings without opening the computer or handling the card. SCSISelect also enables you to low-level format or verify the disk media of your SCSI hard disk drives. The following table lists the available and default settings for each SCSISelect option. The settings that are marked as “Auto-sync” are automatically synchronized for both SCSI channels—for example, if you change the Boot Channel option to B First on Channel A, the change will apply to Channel B as well. All other options can be set separately for each of the two SCSI channels.

The default settings are appropriate for most systems and should not be changed. Run SCSISelect if you need to change or view current settings, or if you need to use the SCSI disk utilities.

SCSI Bus Interface Definitions

• Host Adapter SCSI ID—(Default: 7) Sets the SCSI ID for the SCSI controller. The Adaptec 7899W is set at 7, which gives it the highest priority on the SCSI bus. We recommend that you do not change this setting.

• SCSI Parity Checking—(Default: Enabled) When set to Enabled, verifies the accuracy of data transfer on the SCSI bus. Leave this setting enabled unless any SCS I device connected to the Adaptec 7899W does not support SCSI parity.

• Host Adapter SCSI Termination—(Default: Automatic) Determines the termination setting for the SCSI controller. The default setting is Automatic, which allows the SCSI controller to adjust the termination as needed depending on the configuration of the connected SCSI devices. We recommend that you do not change this setting.

Boot Device Options

• Boot Channel—(Default: A First) Specifies which of the two SCSI channels the boot device is con- nected to (if the computer boots from a SCSI device). If you change this setting, the change automatically applies to both SCSI channels.

• Boot SCSI ID—(Default: 0) Specifies the SCSI ID of your boot device. We recommend that you do not change the default setting.

• Boot LUN Number—(Default: 0) Specifies which LUN (Logical Unit Number) to boot from on your boot device. This setting is not valid unless Multiple LUN Support is Enabled

SCSI Device Configuration Options

SCSI Device Configuration options can be set individually for each connected SCSI device.

Note: To configure settings for a SCSI device, you must know its SCSI ID.

• Sync Transfer Rate—(Default: 160) Determines the maximum synchronous data transfer rate that the SCSI controller supports. We recommend that you leave the maximum (default) value of 160 MBytes/sec.

• Initiate Wide Negotiation—(Default: Yes) When set to Yes, the SCSI controller attempts 16-bit data transfer (wide negotiation). When set to No, the SCSI controller uses 8-bit data transfer unless the SCSI device requests wide negotiation.

Note: Set Initiate Wide Negotiation to No if you are using an 8-bit SCSI device that hangs or exhibits other performance problems with 16-bit data transfer rate enabled.

• Enable Disconnection—(Default: Yes) When set to Yes, allows the SCSI device to disconnect from the SCSI bus. Leave the setting at Yes if two or more SCSI devices are connected to the SCSI chip. If only one SCSI device is connected, changing the setting to No results in slightly better performance.

• Send Start Unit Command—(Default: Yes) When set to Yes, the Start Unit Command is sent to the SCSI device at bootup.

http://www.tyan.com

The following three options have no effect if the SCSI BIOS is disabled. (The SCSI BIOS is normally enabled by default.)

• Enable Write Back Cache—(Default: N/C) Can be used to enable or disable the write-back cache on SCSI disk drives connected to the host adapter. Leave this option at its default setting of N/C (no change), which usually allows for optimum drive performance.

• BIOS Multiple LUN Support—(Default: No) Leave this setting at No if the device does not have multiple Logical Unit Numbers (LUNs). When set to Yes, the SCSI controller BIOS provides boot support for a SCSI device with multiple LUNs (for example, a CD “juke box” device in which multiple CDs can be accessed simultaneously).

• Include in BIOS Scan—(Default: Yes) When set to Yes, the SCSI controller BIOS includes the device as part of its BIOS scan at bootup.

Advanced Configuration Options

Note: Do not change the Advanced Configuration Options unless absolutely necessary.

• Reset SCSI Bus at IC Initialization—(Default: Enabled) When set to Enabled, the SCSI controller generates a SCSI bus reset during its power-on initialization and after a hard reset.

• Display <Ctrl> <A> Messages during BIOS Initialization—(Default: Enabled) When set to Enabled, the SCSI BIOS displays the Press <Ctrl> <A> for SCSISelect (TM) Utility! message on your screen during system bootup. If this setting is disabled, you can still invoke the SCSISelect utility by pressing <Ctrl> <A> after the SCSI BIOS banner appears. If you change this setting, the change automatically applies to both SCSI channels.

• Extended BIOS Translation for DOS Drives > 1 GByte—(Default: Enabled) When set to Enabled, provides an extended translation scheme for SCSI hard disks with capacities greater than 1 GByte. This setting is necessary only for MS-DOS 5.0 or above; it is not required for other operating systems.

Caution: Changing the translation scheme destroys all data on the drive. Be sure to back up your disk drives before changing the translation scheme.

Use the MS-DOS Fdisk command to partition a disk larger than 1 GByte controlled by the SCSI BIOS, when using DOS.

• Verbose/Silent Mode—(Default: Verbose) When set to Verbose, the SCSI BIOS displays the host adapter model on the screen during system buildup. When set to Silent, the message will not be displayed during bootup. If you change this setting, the change automatically applies to both SCSI channels.

• Host Adapter BIOS (Configuration Utility Reserves BIOS Space)—(Default: Enabled) Enables or disables the SCSI BIOS. If you change this setting, the change automatically applies to both SCSI channels.

• Leave at Enabled to allow the SCSI BIOS to scan and initialize all SCSI devices at initial bootup.

• Set to Disabled: Not scan if the devices on the SCSI bus (e.g. CD-ROM drives) are controlled by

software drivers and do not need the BIOS, and you do not want the BIOS to scan the SCSI bus.

• Set to Disabled: Scan Bus if you don’t need the BIOS, but want to scan SCSI devices on the bus.

The following four options on the next page have no effect when the SCSI BIOS is disabled. (The SCSI BIOS is normally enabled by default.)

Thunder K7 S2462

• Domain Validation—(Default: Enabled) Determines what kinds of SCSI devices are connected and reduces data transfer speed if it detects older legacy SCSI devices. Displays the resulting data transfer rate. If you change this setting, the change automatically applies to both SCSI channels.

• Support Removable Disks Under BIOS as Fixed Disks—(Default: Disabled) Determines which removable-media drives are supported by the SCSI controller BIOS. The options are as follows:

- Disabled— No removable media drives are trea ted as hard disk drives. Software drivers are then

required from the vendor, because the drives themselves are not controlled at all by the BIOS.

NOTE: You may lose data if you remove a removable-media cartridge from a SCSI drive con- trolled by the SCSI controller BIOS while the drive is on. If you want to be able to remove the media while the drive is on, install the removable-media software driver and set Support Removable Disks Under BIOS as Fixed Disks to Disabled.

- Boot Only—Only the removable media drive designated as the boot device is treated as an HDD

- All Disks—All removable media drives supported by the BIOS are treated as HDDs

- BIOS Support for Bootable CD-ROMs—(Default: Enabled) When set to Enabled the SCSI

controller BIOS allows the computer to boot from a CD-ROM drive.

- BIOS Support for Int 13 Extensions—(Default: Enabled) When set to Enabled, the SCSI controller BIOS supports Int 13h extensions as required by Plug-and-Play. The setting can be either enabled or disabled if your system is not Plug-and-Play

ATX: the form factor designed to replace the AT form factor. It improves on the AT design by rotating the board 90 degrees, so tha t the IDE connecto rs are close r to the drive b ays, and the CPU is closer to the power supply and cooling fan. The keyboard, mouse, USB, serial, and parallel ports are built-in.

BBS (B 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.

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 th e ne ed ed i n for mat ion is stored in the SRAM instead o f in the sl ow DR AM . Note that the cache is also mu ch sm al le r th an your re gu lar m em or y: a typi ca l cach e size i s 51 2KB , wh ile you may have as much as 4GB of regular memory.

A ty pical setup would b e a ca che si ze o f 512KB , an d a ca cheable area of 5 12MB. 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”.

DRAM (Dynamic RAM): wide ly available, very afford able form of RAM whi ch 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 (E

rror 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 (E unlike normal ROM, be upd ated. T his allow s you to keep up with ch anges in th e BIOS pro gram s withou t having to buy a new chip. Tyan’s BIOS updates can be found at http://www.tyan.com

ESCD (E in the system BIOS. This information helps properly configure the system each time it boots.

Fault-tolerance: a term describi ng a s yste m wher e one c ompo nen t can qu ic kly be repl ace d with out caus ing a loss of service, such as in a RAID system.

Firmware: low-level software that controls the system hardware.

Form factor: an i nd ust ry t erm fo r the size, sh ape , p ow er su ppl y typ e, a nd ext ern al c onn ecto r 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 form of encryption. One system, typically the server, sends an encryption scheme to

another agent, typically a client. Thus, the client’s data is protected during transmittal to the server.

HDD: stands for H

H-SYNC: controls the horizontal synchronization/properties of the monitor.

lectrically Erasable Programmable ROM): also called Flash BIOS, is a ROM chip which can,

IC (I

ntegrated Device/Drive Electronics): a simple, self-contained HDD interface. It can handle drives up

IDE (I to 8.4 GB in size. Almost all IDE s sold now are in fact Enhanced IDEs (EIDEs), with maximum capa city determined by the hardware controller.

IDE INT (IDE Interrupt): a hardware interrupt signal that goes to the IDE.

I/O (I

nput/Output): the connection between your computer and another piece of hardware (mouse, key-

board, etc.)

Thunder K7 S2462

Initial Program Load ( IPL): a feature built into BBS-compliant devices, describing those devices as

capable of loading and execu ting an OS, as w ell as being able to pro vide control ba ck to the B IOS 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 t o each IRQ line; d oubling u p devices o n IRQ lin es can lock u p your sys tem. Plug-n-Play operating systems can take care of these details for you.

ISA (I

ndustry 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 syste m s end s da ta o ut t o a per iphe ra l device, and it waiting for the p erip her al 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 (O 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 (P 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 P modes use the C PU for dat a transfer ( in contrast, D MA channel s 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 fast secondary cache. It is used as a secondary cache because SRAM is slower

than SDRAM, but usually large r. Data is cached first to the fa ster prim ary cache, and then, when the pr imary cache is full, to the slower secondary cache.

Pipelining: improves system perform ance by allowing the CPU to begin exe cuting a second instru ction before the first i s com pleted. A pipeline can be likened to an asse mbly line, with a g iven pa rt of th e pipeline repeatedly executing a set part of an operation on a series of instructions.

PM timers (P utes until the system times out and enters sleep, suspend, or doze mode.

PnP (P require little set-up to use. Novice end use rs can simply plu g them into a compu ter that is run ning on a Plug-n-Play aware operatin g system ( such as Win dows 98), and go to wo rk. Devices a nd oper ating systems that are not Plug-n-Play require you to reconfigu re your system each time you ad d or change any part of your hardware.

PXE (P agement 2.0 baseline sp ecification . PXE was de signed to de fine a standa rd set of pr eboot pro tocol services within a client, towards the goal of allowing networked-based booting to boot using industry standard protocols.

RAID (R on many hard drives. B y using this m ethod, the data is sto red redundan tly, also the multiple hard drives willl appear as a single drive to the operating system. RAID level 0 is is known as striping, where data is striped (or overlapped) acro ss multiple hard dri ves, but offers no fault-tolerance. RAID level 1 is known as mirroring, which stores th e data within at least two hard dr ives, but does not stripe. RAID level 1 also allows for faster access time and fault-toleranc e, since either hard dr ive can be read at the s ame time. RAID level 0+1 is both str iping and mir roring, providing fault-toler ance, striping, an d faster access all at the same time.

RAM (R without touching the adjacent data, is ofte n used to refer to the system’s main memory. This memory is available to any program running on the computer.

lug-n-Play): a design standard that has become ascendant in the industry. Plug-n-Play devices

reboot Exe c uti o n Environment): one of four components that together make up the Wired for Man-

edundant Array of Independ ent Disks): a way for the same dat a to be stor ed in different places

andom Access Memory): technically refers to a type of memory where any byte can be accessed

ROM (R

ead-Only Memory): a storage chip wh ich contains the BIOS ; the basic instructions req uired to

boot the computer and start up the operating system.

SDRAM (S addresses open simultaneo usly. By transferring data alternat ely from one set of ad dresses and th en the other, SDRAM cuts down on the delays associated with non -synchronous RAM, which mus t close one address bank before opening the next.

Serial port: called as such because it tran smits 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).

Thunder K7 S2462

ynchronous Dynamic RAM): called as such because it can keep two sets of memory

SIMM (Single In-line Memory Module): formerly the most common f orm of RAM for m otherboa rds. They

must be installed in pairs, and do not have the carrying capacity or the speed of DIMMs.

Sleep/Suspend mode: in this mode, all devices except the CPU shut down.

tatic RAM): unlike DRAM, th is type of RAM does not need t o be refreshed in order to pre vent

SRAM (S data loss. Thus, it is faster, and more expensive.

Standby mode: in this mode, the video and fixed disk drive (usually the HDD) shuts 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

the proper UltraDMA controller, your system cannot take advantage of the higher data transmission rates of the new UltraDMA/UltraATA HDDs.

USB (U

niversal Serial Bus): a ver satile port. T his one po rt type ca n functi on as a serial, pa ral lel, mouse , keyboard, or joystick port. It is fas t enough to supp ort video transfer, and is capable of supp orting up to 127 daisy-chained peripheral devices.
