Icons

In order to help you navigate this manual and set up your system, wehave added several icons to our format.

This icon alerts you to particularly important details regard-ing the setup or maintenance of your system. This iconoften appears next to information that may keep you from

damaging your board or system. While we will often point out the mostvital paragraphs in a chapter, you should always read every word in thetext. Failing to do so can lead to exasperation and expense.

Wherever possible, we have included step-by-step instruc-tions for setting up your system, which are indicated bythis icon. However, it is in your best interest to read an

entire section (and perhaps the entire manual) before you begin tofiddle with your motherboard.

While we have alerted you to potential dangers in severalplaces in the manual with this icon, these warnings shouldnot be regarded as the whole of your safety regimen. Never

forget that computers are electrical devices, and are capable of deliver-ing a shock. Prevent damage to yourself and to your board: alwaysensure that your system is turned off and unplugged whenever you areworking with it, and that you are equipped with a static safety device.

Technical Support

If a problem arises with your system, you should turn to your dealer forhelp first. Your system has most likely been configured by them, andthey should have the best idea of what hardware and software yoursystem contains. Hence, they should be of the most assistance. Further,if you purchased your system from a dealer near to you, you canactually bring your system in to them to have it serviced, instead ofattempting to do so yourself (which can have expensive consequences).

If your dealer is unable to assist you,try our web page, http:// www.tyan.comuser newsgroup, alt.comp.periphs.mainboard.tyantechnical support phone line, (510) 440-8808or e-mail address [email protected]

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

What’s the first thing I should do?The first thing you should do is read this user’s manual. It containsimportant information which will make configuration and setup mucheasier.

The next step is to properly ground yourself. First, unplug the powerfrom your computer case and then touch the metal casing of the powersupply or any metal part on the computer case. This will discharge anyelectricity from your body. Take the motherboard out of the cardboardbox and static bag, holding it by its edges, and place it on a groundedanti-static surface, component side up. Inspect the board for damage.

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEENDAMAGED!

Press down on any of the socket ICs if it appears that they are notproperly seated (the board should still be on an anti-static mat). Do nottouch the bottom of the board. Remember, don’t take any electronicdevice out of its protective bag until you are ready to actually install itinto the computer case. If you don’t discharge yourself and you zap themotherboard or adapter card, problems may not arise immediatelybecause electrostatic discharge damage, unlike physical damage, causesthe device to fail over time.

Install the motherboard into your case.Follow the instructions provided by the case manufacturer for properinstallation guidelines. TYAN recommends that you use only one screwto hold down the motherboard. The rest of the mounting holes should beused for the plastic standoffs. If your case does not have a hole for astandoff, simply cut off the bottom of the plastic standoff so that the flatportion rests on the metal. The adapter cards and the screws holdingthem down will keep your board flat. The fastening screw should notshort any of the traces on the motherboard. Make certain that you donot overtighten the screw, as it will damage the motherboard andpossibly break internal traces in the surrounding area. The hole you

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

Plug in the power connector as shown.The photos below show the ATX power connector before (Figure 1) andafter (Figure 2) it has been plugged in.

The plastic clip on the power connector should lock over the plastic tabon the onboard connector. You shouldn’t be able to plug the powerconnector in any other way but just to be safe, make sure it looks likeFigure 2 above. Make certain that you do not miss any pins because, ifyou do, you will void your warranty and cause damage to yourself oryour motherboard when you turn the system on. After connecting thepower, make sure the connector is seated firmly into its socket so it willnot become loose or fall off when the computer is jostled or moved.Note: Tyan recommends using an ATX power supply that con-forms to industry standard revision 2.01.

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

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

In Figure 3 you can seehow the IDE cablesshould look when theyare connected to yourhard drive. Notice howPin 1 (denoted by a redstripe) is connected sothat it is next to thepower connector of thedrive. In most cases,this is the proper way ofconnecting your IDEcable to the hard drive.Figure 4 shows the IDEcable properly con-nected to themotherboard.

Contact your hard disk drive manufacturer or documentation for moreinformation.

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.

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


Figure 5

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 yourinstallation instructions or call your dealer if you are unsure aboutattaching floppy drives. Refer to Figure 5 on the previous page for adetailed anatomy of the floppy cable. Remember, you can only have 2floppy drives connected at any given time.

The color stripe on the cable should face toward the top of yourchassis, or toward the big white B printed on the motherboard. Pleaserefer to your documentation for proper installation, or see Figure 4 onpage 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 anothersingle 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, ormotherboard may be faulty. Try another cable or floppy drive toverify.

• Light on the floppy is on constantly: a dead give-away that thecable is on backwards. Reverse the cable at the motherboard endand try again.

Next are the Com and Printer ports.

Warning: When plugging in your keyboard and mouse, or whenplugging anything into a serial or Com port, make sure that the power isoff. Connecting these devices and ports while the power is on is called“hot plugging,” and may damage your system.

Figure 6 at the top of the next page shows the ATX double row connec-tors on this board. The Com and Printer ports, as well as the otherports, are labeled.

Note: Only TYAN cables will work on this motherboard. If you areusing an existing case with old cables, your system will not functionproperly. Use only TYAN-approved cables.

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

The PS/2 connectors are probably quite familiar to you. The USBconnectors, 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 videotransfer, and is capable of supporting up to 127 daisy-chained periph-eral devices. Close-ups of the USB connector, as well as of the USBand PS/2 ports, are on the following page.

Figure 7 shows the USB ports and Figure 8 the PS/2 ports.

Installing your add-in cards is relatively simple but...there are a few rules you need to follow when plugging in a card. Inorder to assure proper operation and a quick installation, adhere to theseguidelines:• 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 Masteror Slave device.

• NEVER force a card into a slot. If it doesn’t fit, look at the socketon the computer to make sure there are no wires or otherobstructions to the slot.

• NEVER plug an ISA card into a PCI slot or a PCI card in an ISAslot. You will void your warranty and damage your system board ifyou 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 ofthe card into the socket first and then the other. This will create a

Figure 7 Figure 8

!important!

http://www.tyan.com

18


rocking motion between the card and the slot and it will damage thepins within the socket.

• Make sure that the cards are seated securely into the slots.• 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 problemswith installation. However, if you do encounter any problems, have aqualified professional install your cards for you or contact your cardmanufacturer.

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

Next, you need to install your memory.Since TYAN boards are manufactured with performance in mind, youshould use add-in components that match. Some DIMM modules mayseem to be high quality because of name or feel but that does notguarantee real-world usability. Some cheaper or OEM memory mayhave brand-name components, but they may be on inferior or substan-dard parts which do not meet the critical tolerances our productsrequire. Because of this, your memory may not work correctly in aTYAN board though it may work well in a competitor’s board. This isbecause many of our competitors do not adhere to the strict tolerancesrequired for high performance. If you buy a TYAN board, you aregetting the best system available. To make installation easy and troublefree, get high quality parts. Some brands we recommend are AdvantageMemory, Corsair Microsystems, Millenium, Kingston Memory, QesTecIncorporated, Unigen, Micron Technology, and Crucial Technology.These DIMMs have proven to be very stable on our boards and performextremely well.

Figure 9

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

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

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

Finally, install your CPU.Pentium II processors (233 through 450MHz) can be used on the Tiger100. Please refer to pages 29-30 for the correct CPU jumper settings foryour board. Remember:• The CPU is a sensitive electronic component and it can easily be

damaged by static electricity. Do not touch the CPU pins with yourfingers.

• Before the CPU is installed, the motherboard must be placed on aflat surface. You should be able to insert the CPU with minimal, butfirm, 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 12below). These two types of processors are essentially the same indesign; the only difference lies in their cooling methods. The active

processor is equipped with a cooling fan and heat sink, while thepassive processor is equipped with a heat sink alone. Both types ofCPUs provide the user with the same performance, and both types canbe installed in the Pentium II slot on the Tiger 100 board.

Figure 11 Figure 12

Installing CPU Retention ModulesInstallation of a Pentium II processor requires a CPU retention module,which is first secured ontothe motherboard.

To attach the retentionmodule, place themotherboard on a flatsurface. Locate the key pinon one end of the Pentium IIslot on the board. Thencarefully line up the keynotch on the retentionmodule with the key pin onthe Pentium II slot (the keypin on the Pentium II slotindicates the correctorientation of the CPU).

Drop the retention module (Figure 14 on the following page) down overthe Pentium II slot so that the retention module sits flat against themotherboard. Tighten the screws in a clockwise manner to secure the

module to the board. Warning: Do notovertighten the screws as you may damagethe module and/or the motherboard.Installing the Active ProcessorWhen the retention module is securely in-stalled, you are ready to plug in the CPU.Press down firmly on the CPU until you heara “click” (see Figure 15). This clicking soundindicates that the CPU is fully locked into the retention module. If you

have an active processor, you will also need to con-nect the CPU’s cooling fan cable to the cooling fanpower connector on the board.

Locate the cooling fan connector (e.g. FAN1) on themotherboard. Plug the CPU’s cooling fan cable intothe cooling fan connector on the board. There will be aplastic clip assembly similar to that of the ATX powerconnector that will force you to connect the fan cablecorrectly (see Figure 16 below).

Figure 16

Figure 14

Figure 15

Installing the Passive ProcessorThe installation of the passive processor differs only slightly from thatof the active processor. Your passive CPU package should contain oneCPU retention module, one heat sink retention bracket with mountinglocks, two mounting attachments, and one heat sink lock.Install theretention module as explained in the active processor section.

The heat sink mount (Figure17) has two pins on thebottom and four pins on thetop. Notice that the bottomtwo pins are of differentsizes. The size of the pins and

the holes in the motherboard will determine the correct orientation.When the bracket is correctly installed, the four pins on top will be rightnext to the Pentium II CPU slot.

Insert the heat sink mount into the holes on the motherboard. When thebracket is properly inserted into the holes on the motherboard, you willhear a clicking noise.

Align the CPU with the CPU retention module. Make sure the heat sinkis lined up with the heat sink mount bracket. If you put the CPU in thewrong way, you may damage the CPU, the motherboard, and/or theCPU socket. Slowly press down on the CPU module until the CPUlocks into place. You will hear a clicking noise when the CPU is lockedsecurely into the module.

The heat sink lock (Figure 18) hasfour notches which will correspondto the four pins on the heat sinkmounting bracket. Gently slide thelock between the heat sink and theheat sink mounting bracket until both sides of the lock are firmlysecured. A clicking sound will be heard when the lock is securelyfastened to the heat sink mounting bracket. To remove the lock from

Figure 17

the heat sink mounting bracket, gently press theends of the locks inward and pull.

Lock the heat sink mount to the board byinserting the two mounting locks (Figure 19)into the pins of the heat sink mounting bracketwhich are now below the mainboard. There willbe a click when the locks are securely fastened.

Removing the CPU.To remove the CPU, move the locks to the center of the CPU. A clickwill be heard when the CPU has been unlocked. Gently pull up on theCPU, taking care not to bend the motherboard or the CPU retentionmodule.

To remove the lock from the retention module, gently press the ends ofthe locks inward and pull.

You are done.Other than checking the jumper settings and cable connections andputting the case back on, you are done. Installing a new motherboardmay sound difficult, but by following these directions, you should havea fairly uneventful time installing our products. If you do encounterproblems, your dealer will be able to help you, or you can consult oneof our many technical support resources (see page 8).

Soft Power Connector

The Soft Power Connector is located on pins 1 and 2 of jumper blockJ10. The Tiger 100 uses the PIIX4e chip for power management,including turning on and off the system. If the Power Button Functionoption in the Power Mangement Menu is set to On/Off (which is thedefault), pressing the power button once, after the BIOS has booted up,will turn the system on and off. If the Power Button Function option isset to Suspend, pressing the power button once will wake the system orsend it in to Suspend mode. In this case, you cannot turn the system offunless you shut down through the Windows operating system or youhold the power button down for four seconds.

Speaker Connector Installation

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

Hardware Reset Switch ConnectorInstallation

The Reset switch on your case’s display panel provides you with theHardware Reset function, which is the same as power on/off. Thesystem 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 ofjumper block J10.

Chassis Intrusion Alarm Connector

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

Windows 95 Users:You may encounter problems with some of the devices in the Intel 82371EBchipset. Neither the PCI Bridge nor the PCI Universal Serial Bus deviceIDs for this chipset (also called PIIX4e) are recognized by Windows 95.This is a software problem, not a hardware problem, and can be easilyremedied by either upgrading to Windows 98 or by installing the Win-95Patch found on the Tyan Driver CD and on the Tyan internet and ftpsites: http://www.tyan.com/html/drivers.html or at ftp://download.intel.com/design/pcisets/busmastr/setupex.exe. Note that USB requires Windows95 OSR 2.1 or above; please contact Microsoft for the USB update.

CMOS RTC

The 440BX AGPset includes a Real Time Clock (RTC) circuit, whichprovides the date and time for the system. If the external battery forthe RTC is low, it will prevent your system from POSTing, and you willnot get a display. Normally the life span of anexternal battery is 2 years. If yours is runninglow, you will need to replace it with a new3V lithium battery (Sony CR2032).

Flash EEPROM

The Tiger 100 uses flash memory to storeBIOS programs. It can be updated as newversions of the BIOS become available. Youcan upgrade your BIOS easily using the

Hardware CMOS & Password Reset

If you have been locked out of your system because you forgot yourpassword or set the CMOS incorrectly, follow the instructions below.

1. Power off the system2. Set jumper JP3 to pins 2 and 3 (see previous page for location of JP3).3. Wait 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 theCMOS to the BIOS defaults.

RAM Installation

The Tiger 100 uses a 64-bit data path from memory to CPU and canaccommodate up to 1024MB of SDRAM. The 168-pin DIMMs mustbe of the 3.3V, unbuffered variety. The position of the notch in theDRAM key position will tell you whether or not a DIMM is unbuffered(see the figure below). All installed memory will be automaticallydetected, 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.

Cache Memory

Penitum II processors have the L2 (Level 2) cache built into theirarchitecture, 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 acacheable memory area of 512MB. The Celeron CPU may have noonboard L2 cache or 128KB.

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

Q: My system sometimes becomes unstable. How should I check thesystem?A: The first thing to do is to check and see if you have any deviceconflict in address, IRQ, or DMA. If you are using Windows 95, theDevice Manager is a good place to start. Please consult your operatingsystem manual for details. Second of all, slowing down the memorytiming in the BIOS’s chipset setup section will help the situation, aswell. Many memory modules are not suitable for high performancesystems 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. The440BX AGPset supports bus speeds of 100MHz, and EDO memorydoes not. You must use SDRAM (which does support 100MHz busspeeds) on this board.

Q: What is AGP?A: AGP (Accelerated Graphics Port) is a new bus architecture for 3Dgraphics. The AGP slot eliminates the PCI bandwidth bottleneck by

RFUBuffered

Unbuffered

168-pin DIMM

bypassing the PCI interface and accessing the system memory directly.Currently, the AGP supports 1X and 2X modes, which yield bandwidthsof 264MB/s (at 33MHz bus speed) and 533MB/s (at 66MHz busspeed), respectively. Compare this with the mere 132MB/s (at 33MHzbus speed) that you get with the PCI bus.

Q: Does my operating system support AGP?A: Currently, only Windows 98 and Windows NT 5.0 will have built-insupport for AGP. Some AGP cards require Windows 95 OSR2.1 or aspecial driver from Intel. Please check with your graphics vendor formore details.

Advanced Setup

The Advanced Setup options included in the AMIBIOS Setup for theTiger 100 are described in this chapter. Select Advanced Setup fromthe AMIBIOS Setup main menu to display the Advanced Setup options.

Default Settings

Every option in AMIBIOS Setup contains two default values: a Fail-Safe default and the Optimal default value. You can also choose torestore the original BIOS settings (i.e. those that your board came with)at any time.

Optimal DefaultsThe Optimal default values provide optimum performance settings forall devices and system features.

Fail-Safe DefaultsThe Fail-Safe default settings consist of the safest set of parameters.Use them if the system is behaving erratically. They should always workbut do not provide optimal system performance characteristics.

Note that you must create a supervisor passwordbefore you create a user password. If you select the User Securityoption first, the following dialog box will appear:

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

Once you have entered your new password, you will be asked toconfirm it. If the two passwords do not match, you will be prompted toenter a new password, and then to confirm it. This will continue untilyou enter the same series of characters both times. Once this is accom-plished, a dialog box will appear and notify you that the Supervisor

1. From the DOS prompt, rename the BIOS file that you have down-loaded 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. Thesystem will begin to read from the A: drive, and write the BIOSinformation contained on the floppy disk in that drive to the EEPROMROM chip. When the BIOS has been totally reprogrammed, thesystem will reboot with the new BIOS in operation.5. If the system does not reboot in three minutes, power down the0system, 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 yoursettings at this time, or simply save and exit the program.

Beep Codes

Fatal errors, which halt the boot process, are communicated through aseries of audible beeps. If AMIBIOS POST can initialize the systemvideo display, it displays the error message. Displayed error messages,in most cases, allow the system to continue to boot. Displayed errormessages are described on pages 74-75. See the top of the next pagefor the beep code chart.

Troubleshooting System Problems

If the computer beeps... then...1, 2, or 3 times... reseat the memory SIMMs or DIPs.

If the system still beeps, replace thememory.

6 times... reseat the keyboard controller chip. Ifit still beeps, replace the keyboardcontroller. If it still beeps, try adifferent keyboard, or replace thekeyboard fuse, if there is one.

8 times... there is a memory error on the videoadapter. Replace the video adapter, orthe RAM on the video adapter.

9 times... the BIOS ROM chip is bad. Thesystem probably needs a new BIOSROM chip.

11 times... reseat the cache memory on themotherboard. If it still beeps, replacethe cache memory.

4, 5, 7, or 10 times... the motherboard must be replaced.

Glossary

ACPI (Advanced Configuration and Power Interface) is a power manage-ment specification that allows the operating system to control the amount ofpower distributed to the computer’s devices. Devices not in use can be turnedoff, reducing unnecessary power expenditure.

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

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

ATAPI (AT A ttachment Packet Interface), also known as IDE or ATA, is adrive implementation that includes the disk controller on the device itself. Itallows 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 AT form factor. It improveson the AT design by rotating the board ninety degrees, so that the IDEconnectors are closer to the drive bays, and the CPU is closer to the powersupply and cooling fan. The keyboard, mouse, serial, USB, and parallel portsare built in.

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

A BBS (Bulletin Board System) is a computer system with a number ofmodems hooked up to it which acts as a center for users to post messages andaccess 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 toensure compatibility.

A buffer is a portion of RAM which is used to temporarily store data, usuallyfrom an application, though it is also used when printing, and in most key-board drivers. The CPU can manipulate data in a buffer before copying it, all atonce, to a disk drive. While this improves system performance--reading to orwriting 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. Informa-tion 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 connec-tion between the processor and system memory, and between the processorand PCI or ISA local buses.

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

A cache is a temporary storage area for data that will be needed often by anapplication. Using a cache lowers data access times, since the neededinformation is stored in the SRAM instead of in the slower DRAM. Note thatthe cache is also much smaller than your regular memory: a typical cachesize 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 notbe confused with the cacheable area, which is the total amount of memorywhich can be scanned by the system in search of data to put into the cache. Atypical setup would be a cache size of 512KB, and a cacheable area of512MB. In this case, up to 512MB of the main memory onboard is capable ofbeing cached. However, only 512KB of this memory will be in the cache atany given moment. Any main memory above 512MB could never be cached.

Closed and open jumpers Jumpers and jumper pins are active whenthey are On or Closed, and inactive when they are Off or Open.

CMOS Complementary Metal-Oxide Semiconductors are chips that holdthe basic start-up information for the BIOS.

The COM port is another name for the serial port, which is so-calledbecause it transmits the eight bits of a byte of data along one wire, andreceives data on another single wire (that is, the data is transmitted in serialform, one bit after another). Parallel ports transmit the bits of a byte on eightdifferent wires at the same time (that is, in parallel form, eight bits at the sametime).

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

DIMM bank DIMM banks are sometimes called DIMM sockets, becausethe physical slot and the logical unit are the same. That is, one DIMMmodule fits into one DIMM socket, which is capable of acting as a memorybank.

DMA Direct Memory Access channels are similar to IRQs. DMA channelsallow hardware devices (like sound cards or keyboards) to access the mainmemory without involving the CPU. This frees up CPU resources for othertasks. As with IRQs, it is vital that you do not double up devices on a singleline. 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 RAMwhich has the unfortunate tendency to lose data if it is not recharged regu-larly (every few milliseconds). This refresh requirement makes DRAMslower three to ten times slower than non-recharged RAM such as SRAM.

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

EEPROM Electrically Erasable Programmable ROM, also called FlashBIOS, is a ROM chip which can, unlike normal ROM, be updated. Thisallows you to keep up with changes in the BIOS programs without having tobuy a new chip. TYAN’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 helpsproperly 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) ormotherboard. The standard form factors are the AT and ATX, althoughTYAN also makes some Baby-AT boards.

A Global timer is an onboard hardware timer, such as the Real TimeClock.

Handshaking is a form of encryption. One system, typically the server,sends an encryption scheme to another agent, typically a client. Thus, theclient’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-containedhard drive interface. It can handle drives up to 8.4GB in size. Almost allIDEs sold now are in fact Enhanced IDEs (EIDEs).

IDE INT (IDE Int errupt) is a hardware interrupt signal that goes to theIDE.

I/O Input/Output is the connection between your computer and anotherpiece of hardware (mouse, keyboard, etc.).

IRQ An Interrupt Request is an electronic request that runs from a hard-ware device to the CPU. The interrupt controller assigns priorities to incom-ing requests and delivers them to the CPU. It is important that there is onlyone 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 ofthese details for you.

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

Latency is the amount of time that one part of a system spends waiting foranother part to catch up. This is most common when the system sends dataout to a peripheral device, and is waiting for the peripheral to send some databack (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 packageother 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 whichoperate within a single system (as opposed to a network bus, which connectsmultiple systems).

The PCI PIO (PCI Programmable Input/Output) modes are the datatransfer modes used by IDE drives. These modes use the CPU for datatransfer (DMA channels do not). PCI refers to the type of bus used by thesemodes 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 secondarycache because SRAM is slower than SDRAM, but usually larger. Data iscached first to the faster primary cache, and then, when the primary cache isfull, to the slower secondary cache.

Pipelining improves system performance by allowing the CPU to beginexecuting a second instruction before the first is completed. A pipeline can belikened to an assembly line, with a given part of the pipeline repeatedlyexecuting a set part of an operation on a series of instructions.

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

PnP is an acronym for Plug and Play, a design standard that has becomeascendant 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 aPlug and Play-aware operating system (such as Windows 95), and go towork. Devices and operating systems that are not Plug and Play require youto reconfigure your system each time you add or change any part of yourhardware.

The term RAM (Random Access Memory), while technically referring to atype of memory where any byte can be accessed without touching theadjacent data, is often used to refer to the system’s main memory. Thismemory 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 thecomputer and start up the operating system.

SDRAM (Synchronous Dynamic RAM ) is so-called because it can keeptwo sets of memory addresses open simultaneously. By transferring dataalternately from one set of addresses, and then the other, SDRAM cuts downon the delays associated with non-synchronous RAM, which must close oneaddress bank before opening the next.

The serial port is so called because it transmits the eight bits of a byte ofdata along one wire, and receives data on another single wire (that is, thedata 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 thespeed of DIMMs.

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

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

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

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

UltraDMA/33 is a fast version of the old DMA channel. UltraDMA isalso called UltraATA. Without UltraDMA your system cannot take advantageof the higher data transmission rates of the new UltraATA hard drives.

Universal Serial Bus or USB, is a versatile port. This one port type canfunction as a serial, parallel, mouse, keyboard, or joystick port. It is fastenough to support video transfer, and is capable of supporting up to 127daisy-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 CPUswithout damaging the sensitive pins. The CPU is lightly placed in an openZIF socket, and the metal lever pulled down. This shifts the processor overand down, guiding it into place on the board.
