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. Hence, they should be of the most assistance. Further, if you purchased your system from a dealer near to you, you can actually bring your system in to them to have it serviced, instead of attempting to do so yourself (which can have expensive consequences).

If your dealer is unable to assist you,

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

procedure

What’s the first thing I should do?

The first thing you should do is read this user’s manual. It contains important information which will make configuration and setup much easier.

Here are some precautions you should follow when installing your motherboard:

(1) Ground yourself properly before removing your motherboard from the antistatic bag. Unplug the power from your computer and then touch any metal part on the computer case. (Or wear a grounded wrist strap.) (2) Hold the motherboard by its edges and do not touch the bottom of

the board. (3) A void touching motherboard components, IC chips, connectors, and leads.

(4) A void touching pins of memory modules and chips. (5) Place motherboard on a grounded antistatic surface or on the

antistatic bag.

DO NOT APPL Y POWER TO THE BOARD IF IT HAS BEEN DAMAGED!

Press down on any of the socket ICs if it appears that they are not properly

important!

seated (the board should still be on an anti-static mat). 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 install it into the computer case. If you do not ground yourself, you risk zapping the motherboard or adapter card. Subsequent problems may not arise immediately because electrostatic discharge damage, unlike physical damage, causes the device to fail over time.

INSTALL

Install the motherboard into your case.

Follow the instructions provided by the case manufacturer for proper installation guidelines. TYAN recommends that you use only one screw to hold down the motherboard. The rest of the mounting holes should be used for the plastic standoffs. If your case does not have a hole for a standoff, simply cut off the bottom of the plastic standoff so that the flat portion rests on the metal. The adapter cards and the screws holding them down will keep your board flat. The fastening screw should not short any of the traces on the motherboard. Make certain that you do not overtighten the screw , as it will damage the motherboard and possibly break internal traces in the surrounding area. The hole you

http://www.tyan.com

Chapter 2

should use is located at the top-center of the board where the adapter cards are fastened to the case.

Plug in the power connector as shown.

The photos below show the ATX power connector before (Figure 1) and after (Figure 2) it has been plugged in.

Figure 1

Figure 2

The plastic clip on the power connector should lock over the plastic tab on the onboard connector. You shouldn’t be able to plug the power connector in any other way but just to be safe, make sure it looks like Figure 2 above. Make

warning

certain that you do not miss any pins because, if you do, you will void your warranty and cause damage to yourself or your motherboard when you turn the system on. After connecting the power, make sure the connector is seated firmly into its socket so it will not become loose or fall off when the computer is jostled or moved. Note: Tyan r ecommends using an A TX power supply that

conforms to industry standard revision 2.01.

http://www.tyan.com

Next, connect your IDE cables (if you’re using IDE hard drives).

Figure 3

The colored stripe on the cable should face toward the top of your chassis, or toward the big white B printed on the motherboard.

In Figure 3 you can see how the IDE cables should look when they are connected to your hard drive. Notice how Pin 1 (denoted by a red stripe) is connected so that it is next to the power connector of the drive. In most cases, this is the proper way of connecting your IDE cable to the hard drive. Figure 4 shows the IDE cable properly connected to the motherboard. Contact your hard disk drive manufacturer or documentation for more information.

Some symptoms of incorrectly installed HDDs are:

• Hard disk drives are not auto-detected: may be a Master/Slave

problem or a bad IDE cable. Contact your vendor.

• Hard Disk Drive Fail message at bootup: may be a bad cable or

lack of power going to the drive.

• No video or beeps on bootup: usually means the cable is on

backwards.

• Hard drive lights are constantly on: bad IDE cable or defective

drives/motherboard. Try another HDD.

• Hard drives do not power up: check power cables and cabling.

May also be a bad power supply or IDE drive.

Now that you have installed your IDE drives, your floppies are next.

Figure 5

Pin 1 on the floppy cable is usually denoted by a red or colored stripe down one side of the cable (see Figure 5). Most of the current floppy drives on the market require that the colored stripe be positioned so that it is right next to the power connector. In most cases, there will be a key pin on the cable which will force you to connect the cable properly .

Drive A: is usually attached to the end of the cable with the twist in it. Drive B: is usually connected to the middle of the cable. Refer to your installation instructions or call your dealer if you are unsure about attaching floppy drives.

http://www.tyan.com

Refer to Figure 5 on the previous page for a detailed anatomy of the floppy cable. Remember, you can only have 2 floppy drives connected at any given time.

The color stripe on the cable should face toward the top of your chassis, or toward the big white B printed on the motherboard. Please refer to your documentation for proper installation, or see Figure 4 on page 13.

Some symptoms of incorrectly installed floppies are:

• Floppy drives are not detected: usually caused by faulty cables,

backward cables, or a bad floppy or motherboard. Try another single floppy drive to verify the problem or try another cable. Also, check to see if the onboard floppy is enabled in the BIOS.

• Floppy Drive Fail message at bootup: the cable, floppy, or

motherboard may be faulty. Try another cable or floppy drive to verify .

• Light on the floppy is on constantly: a dead give-away that the

cable is on backwards. Reverse the cable at the motherboard end and try again.

Next are the Com and Printer ports.

Warning: When plugging in your keyboard and mouse, or when plugging

anything into a serial or Com port, make sure that the power is off. Connecting

these devices and ports while the power is on is called “hot plugging,” and

Note: Only TY AN cables will work on this motherboard. If you are using an existing case with old cables, your system will not function properly . Use only TYAN-approved cables.

Connecting the USB and PS/2 ports.

This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices. The location of these ports is shown in Figure 6 above. Note that, for this board, the PS/2 mouse port is the upper PS/2 port, and the PS/2 keyboard port is the lower PS/2 port.

The PS/2 connectors are probably quite familiar to you. The USB connectors, however, may be foreign. The USB (Universal Serial Bus) is 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. Close-ups of the USB connector, as well as of the USB and PS/2 ports, are on the following page.

Installing your add-in cards is relatively simple but...

there are a few rules you need to follow when plugging in a card. In order to assure proper operation and a quick installation, adhere to these guidelines:

• If you are going to install a PCI-Bus interface card on your system,

be aware that any one of the two 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

important!

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

• NEVER plug an ISA card into a PCI slot or a PCI card in an ISA

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. This will create a rocking motion between the card and the slot and it will damage the pins within the socket.

• Make sure that the cards are seated securely into the slots.

INSTALL

http://www.tyan.com

Chapter 2

Board Installation

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

each other or are shorting.

If you follow these basic guidelines, there shouldn’t be any problems with installation. However, if you do encounter any problems, have a qualified professional install your cards for you or contact your card manufacturer.

Remember, always read the manuals and installation notes that come with the adapter cards. They contain important information which will help you install the components right, the first time.

Next, you need to install your memory.

Since TYAN boards are manufactured with performance in mind, you should use add-in components that match. Some DIMM modules may seem to be high quality because of name or feel but that does not guarantee real-world usability. Some cheaper or OEM memory may have brand-name components, but they may be on inferior or substandard parts which do not meet the critical tolerances our products require. Because of this, your memory may not work correctly in a TY AN board though it may work well in a competitor’ s board. This is because many of our competitors do not adhere to the strict tolerances required for high performance. If you buy a TYAN board, you are getting the best system available. T o make installation easy and trouble free, get high quality parts. Some brands we recommend are Advantage Memory, Corsair Microsystems, Millenium, Kingston Memory, QesTec Incorporated, Unigen, Micron Technology, and Crucial Technology. These DIMMs have proven to be very stable on our boards and perform extremely well.

http://www.tyan.com

Figure 9

To install your DIMMs, line your module up so that the pins fit into the slot.

There is only one way that your DIMM can fit properly . Make sure that the short row of pins is lined up with the short gap in the DIMM slot. Figure 9 shows how to sit the DIMM into its slot. To insert the DIMM, push down vertically on the module with even force, as shown in the photo. Do not shove one end in first; doing so will bend the DIMM pins.

important!

T o lock the DIMM into place, push the plastic clips on either end of the slot onto the notches in the ends of the DIMM (see Figure 10 on the following page). T o remove your DIMM, simply pull the clips back, and pull up on the module.

Figure 10

Place the DIMMs in an anti-static bag as soon as you remove them to avoid static damage.

Finally , install your CPU.

Pentium II processors (233 through 450MHz) can be used on the Tiger 100. Please refer to pages 29-30 for the correct CPU jumper settings for your board.

Remember:

important!

• The CPU is a sensitive electronic component and it can easily be damaged

by static electricity. Do not touch the CPU pins with your fingers.

• Before the CPU is installed, the motherboard must be placed on a flat surface. Y ou should be able to insert the CPU with minimal, but firm, pressure. Do not press down hard on the CPU.

Currently , Intel produces two types of Pentium II processors: the active (or boxed) processor and the passive processor (see Figures 11 and 12 on the next page). These two types of processors are essentially the same in design; the only difference lies in their cooling methods. The active processor is equipped with a cooling fan and heat sink, while the passive processor is equipped with a heat sink alone. Both types of CPUs provide the user with the same performance, and both types can be installed in the Pentium II slot on the Tiger 100 board.

http://www.tyan.com

Active Passive

Installing CPU Retention Modules

Installation of a Pentium II processor requires a CPU retention module, which is first secured onto the motherboard.

T o attach the retention module, place the motherboard on a flat surface. Locate the key pin on one end of the Pentium II slot on the board. Then carefully line up the key notch on the retention module with the key pin on the Pentium II slot (the

indicates the correct orientation of the CPU).

INSTALL

Drop the retention module (Figure 14 on the following page) down over the Pentium II slot so that the retention module sits flat against the motherboard. Tighten the screws in a clockwise manner to secure the module to the board. Warning: Do not overtighten the screws as you

may damage the module and/or the motherboard.

Installing the Active Processor

When the retention module is securely installed, you are ready to plug in the CPU. Press down firmly on the CPU until you hear a “click” (see Figure 15 ). This

http://www.tyan.com

Chapter 2

clicking sound indicates that the CPU is fully locked into the retention module. If you have an active processor, you will also need to connect the CPU’s cooling fan cable to the cooling fan power connector on the board.

Figure 14

Figure 15

Locate the cooling fan connector (e.g. FAN1) on the motherboard. Plug the CPU’s cooling fan cable into the cooling fan connector on the board. There will be a plastic clip assembly similar to that of the ATX power connector that will force you to connect the fan cable correctly (see Figure 16 below).

Figure 16

http://www.tyan.com

Installing the Passive Processor

The installation of the passive processor differs only slightly from that of the active processor. Your passive CPU package should contain one CPU retention module, one heat sink retention bracket with mounting locks, two mounting attachments, and one heat sink lock.Install the retention module as explained in the active processor section.

The heat sink mount (Figure 17) has two pins on the bottom and four pins on the top. Notice that the bottom two pins are of different sizes. The size of the

Insert the heat sink mount into the holes on the motherboard. When the bracket is properly inserted into the holes on the motherboard, you will hear a clicking noise.

Align the CPU with the CPU retention module. Make sure the heat sink is lined up with the heat sink mount bracket. If you put the CPU in the wrong way , you may damage the CPU, the motherboard, and/or the CPU socket. Slowly press down on the CPU module until the CPU locks into place.

You are done.

Other than checking the jumper settings and cable connections and putting the case back on, you are done. Installing a new motherboard may sound difficult, but by following these directions, you should have a fairly uneventful time installing our products. If you do encounter problems, your dealer will be able to help you, or you can consult one of our many technical support resources (see page 8).

Setting Jumpers

In this manual, the terms “closed” and “on” are used when referring to jumpers (or jumper pins) that are active; “open” and “off” are used when referring to jumpers (or jumper pins) that are inactive. Jumpers and pins are connected by slipping the blue plastic jumper connector overtop of two adjacent jumper pins. The metal rod inside the plastic shell bridges the gap between the two pins, completing the circuit. See the drawings below for examples of “on” and “off” pins and jumpers.

FAN4 (Chassis)

The Soft Power Connector is located on pins 1 and 2 of jumper block J10. The Tiger 100 uses the PIIX4e chip for power management, including turning on and off the system. If the Power Button Function option in the Power Mangement Menu is set to On/Off (which is the default), pressing the power button once, after the BIOS has booted up, will turn the system on and off. If the Power Button Function option is set to Suspend, pressing the power button once will wake the system or send it in to Suspend mode. In this case, you cannot turn the system off unless you shut down through the Windows operating system or you hold the power button down for four seconds.

Speaker Connector Installation

ONBOARD

The Tiger 100 provides a 4-pin header to connect the speaker. The speaker is connected to pins 24-27 of jumper block J10.

Hardware Reset Switch Connector Installation

The Reset switch on your case’s display panel provides you with the Hardware Reset function, which is the same as power on/off. The system will do a cold start after the Reset button is pushed. The Reset switch is a 2-pin connector and should be installed on pins 22 and 23 of jumper block J10.

Chassis Intrusion Alarm Connector

The J8 connector is an intrusion alarm, that can be connected to the system chassis. When active (J8 is closed), this alarm will alert the system administrator anytime someone opens the system’s case.

Windows 95 Users:

You may encounter problems with some of the devices in the Intel 82371EB chipset. Neither the PCI Bridge nor the PCI Universal Serial Bus device IDs for this chipset (also called PIIX4e) are recognized by Windows 95. This is a software problem, not a hardware problem, and can be easily remedied by either upgrading to Windows 98 or by installing the Win-95 Patch found on the Tyan Driver CD and on the Tyan internet and ftp sites: http://www.tyan.com/html/ drivers.html or at ftp://download.intel.com/design/pcisets/busmastr/setupex.exe. Note that USB requires Windows 95 OSR 2.1 or above; please contact Microsoft

for the USB update.

important!

CMOS RTC

The 440BX AGPset includes a Real Time Clock (R TC) circuit, which provides the date and time for the system. If the external battery for the R TC is low , it will prevent your system from POSTing, and you will not get a display . Normally the life span of an external battery is 2 years. If yours is running low , you will need to replace it with a new 3V lithium battery (Sony CR2032).

Flash EEPROM

The Tiger 100 uses flash memory to store BIOS programs. It can be updated as new versions of the BIOS become available. Y ou can upgrade your BIOS easily using the Flash Writer Utility (see page 69).

Hardware CMOS & Password Reset

If you have been locked out of your system because you forgot your pass-

word or set the CMOS incorrectly , follow the instructions below .

procedure

1. Power off the system

2. Set jumper JP3 to pins 2 and 3 (see previous page for location of JP3).

3. W ait for 2 seconds, then return jumper JP3 to pins 1 and 2.

4. Power on the system again. By following this procedure, you will erase your password and reset the CMOS to the BIOS defaults.

RAM Installation

The Tiger 100 uses a 64-bit data path from memory to CPU and can accommodate up to 1024MB of SDRAM. The 168-pin DIMMs must be of the 3.3V , unbuffered variety . The position of the notch in the DRAM key position will tell you whether or not a DIMM is unbuffered (see the figure below). All installed memory will be automatically detected, so there is no need to set any jumpers.

Some details of memory installation:

• One unbuffered DIMM must be installed for the system to POST.

• The mainboard supports 8MB, 16MB, 32MB, 64MB, 128MB SDRAM; and

256MB registered SDRAM DIMM modules.

Warning! The 256MB DIMMs r epresented above are REGISTERED memory chips. DO NOT use registered and non-registered memory chips simultaneously! (Check with your memory dealer for more information).

Cache Memory

Penitum II processors have the L2 (Level 2) cache built into their architecture, so there is no need for an L2 cache on the motherboard. The Pentium II processor has a physical L2 cache size of 512KB and a cacheable memory area of 512MB. The Celeron CPU may have no onboard L2 cache or 128KB.

http://www.tyan.com

Frequently Asked Questions

Q: Why don’t I get a display after I put in my old DIMM module? A: The 440BX chipset requires the memory manufacturer to program an

EEPROM chip with SPD (Serial Presence Detection) on the module in order for the BIOS to program the 440BX’s timing registers properly . Your DIMM may not have the EEPROM chip on the module, or the EEPROM may not contain the correct program. Check with your memory vendor for details. The figure below shows a DIMM module with an EEPROM chip.

168-pin DIMM

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 conflict in

address, IRQ, or DMA. If you are using Windows 95, the Device Manager is a good place to start. Please consult your operating system manual for details. Second of all, slowing down the memory timing in the BIOS’s chipset setup section will help the situation, as well. Many memory modules are not suitable for high performance systems and are probably the main source of your problem.

Q: Can I use EDO DIMMs on this motherboard? A: No. The Intel 440BX AGPset does not support EDO memory . The 440BX

AGPset supports bus speeds of 100MHz, and EDO memory does not. You must use SDRAM (which does support 100MHz bus speeds) on this board.

Q: What is AGP? A: AGP (Accelerated Graphics Port) is a new bus architecture for 3D graphics.

The AGP slot eliminates the PCI bandwidth bottleneck by bypassing the PCI interface and accessing the system memory directly. Currently, the AGP supports 1X and 2X modes, which yield bandwidths of 264MB/s (at 33MHz bus speed) and 533MB/s (at 66MHz bus speed), respectively. Compare this with the mere 132MB/s (at 33MHz bus speed) that you get with the PCI bus.

http://www.tyan.com

Chapter 3

Onboard Resource Settings

Q: Does my operating system support AGP? A: Currently , only Windows 98 and W indows NT 5.0 will have built-in support

for AGP . Some AGP cards require W indows 95 OSR2.1 or a special driver from Intel. Please check with your graphics vendor for more details.

Q: Will my motherboard run a PII/Celeron/Mendicino CPU? A:Y es, the BIOS version 1.07 supports Celeron 266-300MHz and the BIOS

version 1.12 supports the Celeron-A (Mendocino) 300-333MHz.

Q: Can I run dual Celeron/Mendocino CPU´s on this motherboard? A: No, both Celeron and Mendocino CPU's are not designed to function in

dual CPU mode even on a dual slot motherboard.

Q: My system will not turn off - why? A: The power button is designed to turn off the system ONLY when you

press/hold the power button for more than 5 seconds. BIOS version 1.12 will provide an option for instant power-off .

Q: When I clear the BIOS with the jumper , it does not clear - why? A: In most cases, BIOS can be cleared by inserting jumper JP3 to the 2-3

position. In some cases, certain brands of power supply need to be UNPLUGGED from a power source in order to clear the BIOS using jumper JP3.

Q: I´m getting a "motherboard resource conflict" - seen in Win95/98 Device Manager as a yellow Exclamation Mark image. How do I clear it up? A: More than likely , you have BIOS version 1.03. Y ou need to install BIOS version 1.07 to resolve this problem.

Q: My Wake-On LAN network burned out my power supply. What should I do? A: You need to use a power supply with 800ma at +5VSB power line. This is because most W ake-On LAN network cards require +5V 750 mA in sleep mode. W e recommend our customer to purchase the ATX power supply with minimum 800 mA at +5V SB output to avoid over-current damage to the power supply.

Q: How can I disable the keyboard detection in the BIOS v.1.12? A: Y ou need to enable the Quick Boot option in CMOS - then the BIOS will not

check for a keyboard.

These options allow you to specify the bus type used by each DMA channel. The settings are PnP or ISA/EISA .

IRQn

These options specify the bus that the specified IRQ line is used on. These options allow you to reserve IRQs for legacy ISA adapter cards. These options determine if AMIBIOS should remove an IRQ from the pool of available IRQs passed to devices that are configurable by the system BIOS. The available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from the pool, you can use these options to reserve the IRQ by assigning an ISA/EISA setting to it. Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O are configured as PCI/PnP. IRQ12 only appears if the Mouse Support option in Advanced Setup is set to Disabled. IRQ14 and 15 will not be available if the onboard PCI IDE is enabled. If all IRQs are set to ISA/EISA and IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ9 will still be available for PCI and PnP devices, because at least one IRQ must be available for PCI and PnP devices. The settings are ISA/EISA or PCI/PnP .

3.7 Supervisor and User Security

You can limit access to the Setup Program or to the system using the Supervisor and User password options (the Supervisor password gives you access to the Setup Program and the system; the User password, only to the system). Note that you must create a supervisor password before you create a user password.

Set Supervisor Password [ Enter ] Setup Help Set User Password [ Enter ]

When you select the Supervisor Security option, a dialog box will appear, allowing you to enter a password. You may either type the password in, or click on the onscreen buttons. Your password must be between one and six characters long.

http://www.tyan.com

Once you have entered your new password, you will be asked to confirm it. If the two passwords do not match, you will be prompted to enter a new password, and then to confirm it. This will continue until you enter the same series of characters both times. Once this is accomplished, a dialog box will appear and notify you that the Supervisor Password has been installed. You may then select the User Security option and enter a password for the user. You can enter a new User password at any time simply by selecting the User Security option, and typing in a new password. T o enter a new Supervisor password, select the Supervisor Security option. You will be asked to enter the current password. After you do so, you will be prompted to enter the new password.

In either the Supervisor or User Security options, pressing <Enter> once when asked for a new password, and a second time when asked to confirm the new password, will uninstall the existing password. Note that uninstalling the Supervisor password uninstalls the User password as well.

3.8 Language Utility

Currently, the BIOS Setup program is available only in English.

3.9 Flash Writer Utility

The AMI Flash Writer Utility is now included in the AMIBIOS, and so it is simpler to upgrade the BIOS of your mainboard. The system BIOS is stored on a flash EEPROM ROM chip on the mainboard which can be erased and reprogrammed by following the directions on the following page.

1. From the DOS prompt, rename the BIOS file that you have downloaded to “amiboot.rom” and copy it on to a floppy disk.

2. Insert the floppy disk with the BIOS upgrade into the A: drive.

3. Turn the power off.

4. While holding the <Ctrl> and <Home> keys, turn the power on. The system will begin to read from the A: drive, and write the BIOS information contained on the floppy disk in that drive to the EEPROM ROM chip. When the BIOS has been totally reprogrammed, the system will reboot with the new BIOS in operation.

5. If the system does not reboot in three minutes, power down the system wait a few seconds, and then turn the power back on again. You will be prompted to press <F1> to run Setup. You may check your settings at this time, or simply save and exit the program.

Beep Codes

Fatal errors, which halt the boot process, are communicated through a series of audible beeps. If AMIBIOS POST can initialize the system video display , it displays the error message. Displayed error messages, in most cases, allow the system to continue to boot. Displayed error messages are described on pages 72-73. See the top of the next page for the beep code chart.

T roubleshooting System Problems

If the computer beeps... then...

1, 2, or 3 times... reseat the memory SIMMs or DIPs.

If the system still beeps, replace the memory.

6 times... reseat the keyboard controller chip. If

it still beeps, replace the keyboard controller. If it still beeps, try a different keyboard, or replace the keyboard fuse, if there is one.

8 times... there is a memory error on the video

adapter. Replace the video adapter, or the RAM on the video adapter.

9 times... the BIOS ROM chip is bad. The

system probably needs a new BIOS ROM chip.

11 times... reseat the cache memory on the

motherboard. If it still beeps, replace the cache memory.

4, 5, 7, or 10 times... for 5 or 7 beeps, first test with a new CPU - if that

does not solve the problem, then motherboard must be replaced.

ACPI (Advanced Configuration and Power Interface) is 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) is 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 66MHz, it supports data transmission during both the rising and falling ends of the clock cycle, yielding an effective speed of 133MHz.

The AT was the original form factor of IBM’ s PC.

A T API (AT Attachment Packet Interface), also known as IDE or ATA, is 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 hard drives.

The ATX form factor was designed to replace the A T form factor . It improves on the AT design by rotating the board ninety 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, serial, USB, 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.

A BBS (Bulletin Board System) is a computer system with a number of modems hooked up to it which acts as a center for users to post messages and access information.

The BIOS (Basic Input/Output System) program 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 .

A buffer is 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 the possibility of losing your data should the system crash. Information stored in a buffer is temporarily stored, not permanently saved.

A bus is 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).

A cache is 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 slower 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 1GB 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.

http://www.tyan.com

Appendix 2

Glossary

In this case, up to 512MB 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 are chips that hold the basic start-up information for the BIOS.

The COM port is another name for the serial port, which is so-called 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).

DIMM Dual In-line Memory Modules are a faster and more capacious form of RAM than SIMMs, and do not need to be installed in pairs.

DIMM bank DIMM banks are 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 are similar to IRQs. DMA channels allow hardware devices (like sound cards 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 and Play devices will take care of this for you.

In Doze mode, only the CPU’s speed is slowed. DRAM Dynamic RAM is a 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 slower three to ten times slower than non-recharged RAM such as SRAM.

EDO RAM (Extended Data-Out RAM) speeds access to memory locations by assuming that memory addresses are static: the next time it looks for a bit of data, it will be at the same spot, or one nearby .

EEPROM Electrically Erasable Programmable ROM, also called Flash BIOS, is a

http://www.tyan.com

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. TY AN’ s BIOS updates can be found at http://www .tyan.com/html/drivers.html

ESCD (Extended System Configuration Data) is a format for storing informa- tion about Plug and Play devices in the system BIOS. This information helps properly configure the system each time it boots.

Firmware is low level software that controls the system hardware.

Form factor is an industry term for the size, shape, power supply type, and

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

A Global timer is an onboard hardware timer, such as the Real T ime Clock.

Handshaking is 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 Hard Disk Drive.

H-SYNC controls the horizontal properties of the monitor.

IC (Integrated Circuit) is the formal name for the computer chip.

IDE Integrated Device (or Drive) Electronics is a simple, self-contained hard

drive interface. It can handle drives up to 8.4GB in size. Almost all IDEs sold now are in fact Enhanced IDEs (EIDEs).

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

I/O Input/Output is the connection between your computer and another piece

of hardware (mouse, keyboard, etc.).

IRQ An Interrupt Request is 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. Happily, Plug and Play operating systems take care of these

details for you.

ISA stands for Industry Standard Architecture. ISA is a slower 8- or 16-bit BUS (data pathway).

Latency is 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 is waiting for the peripheral to send some data back (peripherals tend to be slower than onboard system components).

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) like Compaq or IBM package other companies’ motherboards and hardware inside their case and sell them.

The 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 stands for Peripheral Component Interconnect. PCI is a 32-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).

The PCI PIO (PCI Programmable Input/Output) modes are the data transfer modes used by IDE drives. These modes use the CPU for data transfer (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 is a fast secondary cache. It is used as a secondary cache because SRAM is slower than SDRAM, but usually larger . Data is cached first to the faster primary cache, and then, when the primary cache is full, to the slower secondary cache.

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.

http://www.tyan.com

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

PnP is an acronym for Plug and Play , a design standard that has become ascendant in the industry. Plug and Play devices require little set-up to use. Novice end users can simply plug them into a computer that is running on a Plug and Play-aware operating system (such as Windows 95), and go to work. Devices and operating systems that are not Plug and Play require you to reconfigure your system each time you add or change any part of your hardware.

The term RAM (Random Access Memory), while technically referring 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) is a storage chip which contains the BIOS (Basic Input/Output System), the basic instructions required to boot the computer and start up the operating system.

SDRAM (Synchronous Dynamic RAM) is so-called 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.

The serial port is so called 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).

SIMM Single In-line Memory Modules are the most common form of RAM. They must be installed in pairs, and do not have the carrying capacity or the speed of DIMMs.

SIMM bank/socket SIMM sockets are the physical slots into which you stick SIMM modules. A pair of SIMM sockets form a SIMM bank, and act as a unit. If only one socket is filled, the bank will not operate.

In Sleep/Suspend mode, all devices except the CPU shut down.

http://www.tyan.com

Appendix 2

Glossary

SRAM Static RAM, unlike DRAM, does not need to be refreshed in order to prevent data loss. Thus, it is faster, and more expensive.

In Standby mode, the video and fixed disk drive shut down; all other devices operate normally.

UltraDMA/33 is a fast version of the old DMA channel. UltraDMA is also called UltraATA. W ithout UltraDMA your system cannot take advantage of the higher data transmission rates of the new UltraATA hard drives.

Universal Serial Bus or USB, is 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) is the PC video display standard.

V-SYNC controls the vertical properties of the monitor.

ZIF socket Zero Insertion Force sockets make it possible to insert CPUs

without damaging the sensitive pins. The CPU is lightly placed in an open ZIF socket, and the metal lever pulled down. This shifts the processor over and down, guiding it into place on the board.
