Chapter 1Introduction

Overview

The S1830S and S1830SL (S1830) Tsunami AT is a quality, high performancemainboard designed for Intel Pentium II and Celeron microprocessors. Thismainboard utilizes the Intel 440BX AGPset and can support CPU speeds of233MHz through 450MHz, and host bus speeds of 66MHz or 100MHz. TheTsunami AT also has 100MHz Front Side Bus support, which allows you totake full advantage of 100MHz SDRAM memory modules.

The S1830 mainboard, with built-in AGP slot, provides high performancecapabilities that are ideal for a wide range of demanding applications such asCAD, CAM, CAE, desktop publishing, 3D animation, and video production.

This integrated system board achieves high reliability with numerous featuresand yet is small enough to be supported in a Baby AT form factor. Some of thefeatures included are onboard dual channel PCI PIO, Bus Master IDE andUltraDMA/33, onboard floppy controller, and onboard high speed I/O.

Flexibility and expandability have been designed into the Tsunami AT. With I/O and drive controller support built onboard, the one AGP slot, four PCI andfour ISA slots (one shared, eight usable) are free for numerous add-onepansion cards.

Icons

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

This icon alerts you to particularly important details regarding thesetup or maintenance of your system. This icon often appears nextto information that may keep you from damaging your board orsystem. While we will often point out the most vital paragraphs in a

chapter, you should always read every word in the text. Failing to do so canlead to exasperation and expense.

Wherever possible, we have included step-by-step instructions forsetting up your system, which are indicated by this icon. However,it is in your best interest to read an entire section (and perhaps the

entire manual) before you begin to fiddle with your motherboard.

While we have alerted you to potential dangers in several placesin the manual with this icon, these warnings should not beregarded as the whole of your safety regimen. Never forget thatcomputers are electrical devices, and are capable of delivering a

shock. Prevent damage to yourself and to your board: always ensure that yoursystem is turned off and unplugged whenever you are working with it, and thatyou are equipped with a static safety device.

Technical Support

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

Help resources:1. See FAQ and beep codes sections of this manual.2. See Tyan web site for FAQ, bulletins, driver updates, etc.

http://www.tyan.com3. Contact your dealer or distributor for help BEFORE calling Tyan.4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan5. Email Tyan tech support: [email protected]. Call Tyan tech support: 510-440-8808

Board Installation

Unpacking

The mainboard package should contain the following:(1) S1830S/SL mainboard(1) 40-pin IDE and 34-pin floppy cable pack(1) One PS/2 Mouse cable(1) User’s manual(1) CPU retention module(1) System Managment & Driver CD (Intel LANDesk - 1830SL only)(1) One BX Driver Diskette (1830S only)

Installation

You are now ready to install your mainboard. The mounting hole pattern of theS1830 matches the Baby AT system board specifications. Your chassis shouldbe that of a standard AT mainboard form factor with AT or ATX power supply.

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 contains important

information which will make configuration and setup much easier.

The next step is to properly ground yourself. First, unplug the power from yourcomputer case and then touch the metal casing of the power supply or anymetal part on the computer case. This will discharge any electricity from yourbody. Take the motherboard out of the cardboard box and static bag, holding itby its edges, and place it on a grounded anti-static surface, component sideup. Inspect the board for damage.

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

Press down on any of the socket ICs if it appears that they are not properlyseated (the board should still be on an anti-static mat). Do not touch thebottom of the board. Remember, don’t take any electronic device out of itsprotective bag until you are ready to actually install it into the computer case.If you don’t ground yourself, you risk zapping the motherboard or adaptercard. Subsequent problems may not arise immediately because electrostaticdischarge damage, unlike physical damage, causes the device to fail over time.

Install the motherboard into your case.Follow the instructions provided by the case manufacturer for proper installa-tion guidelines. TYAN recommends that you use only one screw to hold downthe motherboard. The rest of the mounting holes should be used for the plasticstandoffs. If your case does not have a hole for a standoff, simply cut off thebottom of the plastic standoff so that the flat portion rests on the metal. Theadapter cards and the screws holding them down will keep your board flat. Thefastening screw should not short any of the traces on the motherboard. Makecertain that you do not overtighten the screw, as it will damage themotherboard and possibly break internal traces in the surrounding area. Thehole 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 Tsunami AT has both AT and ATX power supply connectors. The softpower on/off functions of Windows 9x and Wake on LAN are only supportedwith ATX power supplies. The photos on the next page show the ATX powerconnector before (Figure 1) and after (Figure 2) it has been plugged in.

Chapter 2Board Installation

The plastic clip on the power connector should lock over the plastic tab on theonboard connector. You shouldn’t be able to plug the power connector in anyother way but just to be safe, make sure it looks like Figure 2 above. Makeabsolutely certain that you do not miss any pins because, if you do, you willvoid your warranty and cause damage to yourself or your motherboard whenyou turn the system on. After connecting the power, make sure the connectoris seated firmly into its socket so it will not become loose or fall off when thecomputer is jostled or moved. Note: Tyan recommends using an ATX powersupply that conforms to industry standard revision 2.01.

If you decide to use an AT power supply instead, connect the power supply tothe board as shown in Figure 3 (Next page).

Note that the black wires are in the center of the two connectors. You shouldnot be able to plug the two power connectors in any other way but just to besafe, make sure you have them connected as shown above. Make absolutelycertain that you do not miss any pins because if you do, you will void yourwarranty and cause damage to yourself or your motherboard when you turnthe system on. After connecting the power, make sure the connectors areseated firmly into their sockets so they will not become loose or fall off duringmovement of the computer.

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

The colored stripe on the cable indicating pin 1 should face towrds the rear ofthe case (towards the ATX connectors).

In Figure 4 (below) you can see how the IDE cables should look when they areconnected to your hard drive. Notice how Pin 1 (denoted by a red stripe) isconnected 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 5(on the next page) shows the IDE cable properly connected to themotherboard.

Contact your hard disk drive manufacturer or documentation for more informa-tion.

Some symptoms of incorrectly installed HDDs are:• Hard disk drives arenot auto-detected: may bea Master/Slave problem ora bad IDE cable. Contactyour vendor.• Hard Disk Drive Failmessage at bootup: maybe a bad cable or lack ofpower going to the drive.• No video or beeps onbootup: usually means thecable is on backwards.• Hard drive lights areconstantly on: bad IDEcable or defective drive ormotherboard. Try anotherHDD.• Hard drives do notpower up: check powercables and cabling. Mayalso 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 stripe downone side of the cable (see Figure 6 on next page). Most of the current floppydrives on the market require that the colored stripe be positioned so that it isright next to the power connector. In most cases, there will be a key pin on thecable 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 installationinstructions or call your dealer if you are unsure about attaching floppy drives.Refer to Figure 6 for a detailed anatomy of the floppy cable. Remember, youcan only have 2 floppy drives connected at any given time.

The colored stripe on the cable indicating pin 1 should face towards the rear ofthe case (towards the ATX connectors), as with the IDE cables. Please refer toyour documentation for proper installation, or see Figure 5 on page 14.

Some symptoms of incorrectly installed floppies are:• Floppy drives are not detected: usually caused by faulty cables, backwardcables, or a bad floppy or motherboard. Try another single floppy drive toverify the problem or try another cable. Also, check to see if the onboardfloppy is enabled in the BIOS.• Floppy Drive Fail message at bootup: the cable, floppy, or motherboardmay 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 onbackwards. Reverse the cable at the motherboard end or the floppy end andtry again.

Next are the Com and Printer ports.

Chapter 2Board Installation

Like the IDE and floppy cables, the colored or red edge of the cable alwaysdenotes pin 1 (Figure 7 previous page). Similarly, pin 1 on the motherboard isalways pointing towards the keyboard connector or edge of the board. TYANcables conform to the IBM standard pinouts and will differ from most othermanufacturers’. Other cables will not work on TYAN boards.

The Printer and Com1 ports are on the same back plate. You want to make surethat you correctly align the connectors with the pins on the board beacusethey are easy to miss. On most TYAN cables, there should be a pin missing onthe motherboard. This is normal since it lines up with a key pin on the I/Oconnectors. This forces you to align the connector in the correct direction.The Printer port and Com2 are easily confused. The Printer cable is alwaysattached with Com1 (Figure 8) where Com2 is supplied seperately on a secondback plate (Figure 9). Remember: Only TYAN cables will work on thismotherboard. If you are using an existing case with old cables, your systemmay not function properly. Use TYAN-approved connectors to ensurecompatibility.

Connecting the PS/2 mouse.This board has a PS/2 mouse port built in. Simply plug your PS/2 mouse intothe PS/2 port; the pins will allow you to plug the mouse in only in the correctway. If you have any trouble locating the port, turn to the full pagemotherboard map on page 25. Warning: When plugging in your keyboardand mouse, or when plugging anything into a serial or Com port, make surethat the power is off. Connecting these devices and ports while the power ison iscalled “hot plugging,” and may damage your system.

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 toassure 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 Slavedevice.

• NEVER force a card into a slot. If it doesn’t fit, look at the socket on thecomputer 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. Youwill void your warranty and damage your system board if you do this.

• When plugging the card in, especially when installing long cards, try topush the entire card in at one time. Don’t force one end of the card into thesocket first and then the other. This will create a rocking motion betweenthe card and the slot and it will damage the pins within the socket.

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

• Before turning on the system, make sure no cards are touchingeach other to prevent shorting.

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

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

Next, you need to install your memory.Since TYAN boards are manufactured with performance in mind, you shoulduse add-in components that match. Some DIMM modules may seem to be highquality because of name or feel but that does not guarantee real-world usabil-ity. Some cheaper or OEM memory may have brand-name components, butthey may be on inferior or substandard parts which do not meet the criticaltolerances our products require. Because of this, your memory may not workcorrectly in a TYAN board though it may work well in a competitor’s board.This is because many of our competitors do not adhere to the strict tolerancesrequired for high performance. If you buy a TYAN board, you are getting the

best system available. To make installation easy and trouble free, get highquality parts. Some brands we recommend are Advantage Memory, CorsairMicrosystems, Millenium, Kingston Memory, QesTec Incorporated, Unigen,Micron Technology, and Crucial Technology. These DIMMs have proven tobe very stable on our boards and perform extremely well.

Figure 10

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 theshort row of pins is lined up with the short gap in the DIMM slot. Figure 10shows how to sit the DIMM into its slot. To insert the DIMM, push downvertically on the module with even force, as shown in the photo. Do not shoveone end in first; doing so will bend the DIMM pins.

To lock the DIMM into place, push the plastic clips on either end of the slotonto the notches in the ends of the DIMM (see Figure 11 on the followingpage). To remove your DIMM, simply pull the clips back, and pull up on themodule.

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

Finally, install your CPU.Pentium II processors (233 through 400MHz) can be used on the Tsunami AT.Please refer to pages 27-29 for the correct CPU jumper settings for your board.

S1830 Tsunami AT

Remember:• 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 mainboard must be placed on a flat

surface. You 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 (orboxed) processor and the passive processor (see Figures 12 and 13 on the nextpage ). These two types of processors are essentially the same in design; theonly difference lies in their cooling methods. The active processor is equippedwith a cooling fan and heat sink, while the passive processor is equipped witha heat sink alone. Both types of CPUs provide the user with the same perfor-mance, and both types can be installed in the Pentium II slot on the TsunamiAT board.

Installing CPU Retention ModulesInstallation of a Pentium II processor requires a CPU retention module, whichis first secured onto the motherboard.

To attach the retention module, place the motherboard on a flat surface. Locatethe key pin on one end of the Pentium II slot on the board. Then carefully line

Figure 11

Chapter 2Board Installation

!impor-tant!

up the key notch on the retention module with the key pin on the Pentium IIslot (the key pin on the Pentium II slot indicates the correctorientation of the CPU).

Figure 12 Figure 13

Drop the retention module(Figure 15 on the followingpage) down over the PentiumII slot so that the retentionmodule sits flat against themotherboard. Tighten thescrews in a clockwise mannerto secure the module to theboard. Warning: Do notovertighten the screws as youmay damage the module and/or the motherboard.

Installing the Active ProcessorWhen the retention module is securely installed, you are ready to plug in theCPU. Press down firmly on the CPU until you hear a “click” (see Figure 16 on thefollowing page). This clicking sound indicates that the CPU is fully locked intothe retention module. If you have an active processor, you will also need toconnect the CPU’s cooling fan cable to the cooling fan power connector on theboard.

Locate the cooling fan connector (e.g. FAN1) on the motherboard. Plug theCPU’s cooling fan cable into the cooling fan connector on the board. There willbe a plastic clip assembly similar to that of the ATX power connector that will

S1830 Tsunami AT

force you to connect the fan cable correctly (see Figure 17 below).

I

Installing the Passive ProcessorThe installation of the passive processor differs only slightly from that of theactive processor. Your passive CPU package should contain one CPU retentionmodule, one heat sink retention bracket with mounting locks, two mountingattachments, and one heat sink lock.Install the retention module as explained inthe active processor section.

The heat sink mount (Figure 18 on the next page) has two pins on the bottomand four pins on the top. Notice that the bottom two pins are of different sizes.The size of the pins and the holes in the motherboard will determine the correctorientation. When the bracket is correctly installed, the four pins on top will be

Figure 15Figure 16

Figure 17

http://www.tyan.com

22

Chapter 2Board Installation

right next 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 will hear aclicking noise.

Align the CPU with the CPU retention module. Make sure the heat sink is linedup with the heat sink mount bracket. If you put the CPU in the wrong way, youmay damage the CPU, the motherboard, and/or the CPU socket. Slowly pressdown on the CPU module until the CPU locks into place. You will hear aclicking noise when the CPU is locked securely into the module.

The heat sink lock (Figure 19)has four notches which willcorrespond to the four pins onthe heat sink mounting bracket.Gently slide the lock betweenthe heat sink and the heat sinkmounting bracket until bothsides of the lock are firmly secured. A clicking sound will be heard when thelock is securely fastened to the heat sink mounting bracket. To remove the lockfrom the heat sink mounting bracket, gently press the ends of the locks inwardand pull.

Lock the heat sink mount to the board byinserting the two mounting locks (Figure 20) intothe pins of the heat sink mounting bracket whichare now below the mainboard. There will be aclick when the locks are securely fastened.

Removing the CPU.To remove the CPU, move the locks to the center of the CPU. A click will beheard when the CPU has been unlocked. Gently pull up on the CPU, takingcare not to bend the motherboard or the CPU retention module.

To remove the lock from the retention module, gently press the ends of thelocks inward and pull.

You are done.Other than checking the jumper settings and cable connections and puttingthe case back on, you are done. Installing a new motherboard may sounddifficult, but by following these directions, you should have a fairly uneventfultime installing our products. If you do encounter problems, your dealer will beable to help you, or you can consult one of our many technical supportresources (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 tojumpers (or jumper pins) that are inactive. Jumpers and pins are connected byslipping the black plastic jumper connector overtop of two adjacent jumperpins. The metal rod inside the plastic shell bridges the gap between the twopins, completing the circuit. See the drawings below for examples of “on” and“off” pins and jumpers.

CPU Settings for 66MHz Bus

CPU Settings for 100MHz Bus

* Due to CPU availability, this speed has not been tested.

The CPU speed is controlled by setting the bus speed (described in BIOSsetup) and by setting the multiplier with the jumpers described above that areappropriate for your CPU and memory. You must have a 100MHz processor torun at a bus speed of 100MHz. Tyan does not recommend and is not respon-sible for functionality or damage to components caused by operating a CPU,memory or any bus at higher than rated speeds (overclocking).

Other Pin Assignments

Soft Power Connector

The Soft Power Connector is located on pins 1 and 2 of jumper block J8. TheTsunami AT uses the PIIX4e chip for powermanagement, including turning on and off thesystem. If the Power Button Function option in thePower Mangement Menu is set to On/Off (which isthe default), pressing the power button once, afterthe BIOS has booted up, will turn the system onand off. If the Power Button Function option is setto Suspend, pressing the power button once willwake the system or send it in to Suspend mode. Inthis case, you cannot turn the system off unlessyou shut down through the Windows operatingsystem or you hold the power button down for fourseconds. The soft power function requires an ATXpower supply.

Speaker Connector Installation

The Tsunami AT provides a 4-pin header to connect the speaker. The speakeris connected to pins 24-27 of jumper block J8.

Hardware Reset Switch ConnectorInstallation

The Reset switch on your case’s display panel provides you with the Hard-ware Reset function, which is the same as power on/off. The system will do acold start after the Reset button is pushed. The Reset switch is a 2-pinconnector and should be installed on pins 22 and 23 of jumper block J8.

External SMI

The EXTSMI (External System ManagementInterface) connector, JP1, is used by someplug-in cards. Certain applications associatedwith these plug-in cards use the interface forhardware control and queries.

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 device IDs forthis chipset (also called PIIX4e) are recognized by Windows 95. This is a soft-ware problem, not a hardware problem, and can be easily remedied by eitherupgrading to Windows 98 or installing the 82371EB patch on the Tyan BX DriverDiskette or CD. The patch can also be downloaded from the Tyan web or ftp siteat 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 orabove; please contact Microsoft for the USB update.

CMOS RTC

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

Flash EEPROM

The Tsunami AT uses flash memory to store BIOS programs. It can be updatedas new versions of the BIOS become available. You can upgrade your BIOSeasily using the Flash Writer Utility (see page 61).

RAM Installation

The Tsunami AT uses a 64-bit data path from memory to CPU and can accom-

modate 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 willtell you whether or not a DIMM is unbuffered (see the figure below). Allinstalled memory will be automatically detected, so there is no need to set anyjumpers.

Some details of memory installation:• At least one unbuffered DIMM must be installed for the system to POST.

• The mainboard supports 8MB, 16MB, 32MB, 64MB, 128MB, and 256MBSDRAM w/SPD and SDRAM+ECC DIMM modules.

• 66MHz or 100MHz SDRAM modules can be used, but you must use100MHz SDRAMs if you wish to take advantage of the 100MHz FrontSide Bus speed.

The table on the next page shows some of the possible memory configura-tions.

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 IIprocessor has a phsyical L2 cache size of 512KB and a cacheable memory areaof 512MB.

A: The 440BX chipset requires the memory manufacturer to program anEEPROM chip with SPD (Serial Presence Detection) on the module in order forthe BIOS to program the 440BX’s timing registers properly. Your DIMM maynot have the EEPROM chip on the module, or the EEPROM may not containthe correct program. Check with your memory vendor for details. The figurebelow shows a DIMM module with an EEPROM chip.

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

Q: Can I use EDO DIMMs on this motherboard?A: No. The Intel 440BX AGPset does not support EDO memory. The 440BXAGPset supports bus speeds of 100MHz, and EDO memory does not. Youmust 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 PCIinterface and accessing the system memory directly. Currently, the AGPsupports 1X and 2X modes, which yield bandwidths of 264MB/s (at 33MHzbus speed) and 533MB/s (at 66MHz bus speed), respectively. Compare thiswith the mere 132MB/s (at 33MHz bus 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-in supportfor AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver fromIntel. Please check with your graphics vendor for more details.

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

IRQnThese options specify the bus that the specified IRQ line is used on. Theseoptions allow you to reserve IRQs for legacy ISA adapter cards. Theseoptions determine if AMIBIOS should remove an IRQ from the pool ofavailable IRQs passed to devices that are configurable by the system BIOS.The available IRQ pool is determined by reading the ESCD NVRAM. If moreIRQs must be removed from the pool, you can use these options to reserve theIRQ by assigning an ISA/EISA setting to it. Onboard I/O is configured byAMIBIOS. All IRQs used by onboard I/O are configured as PCI/PnP. IRQ12only appears if the Mouse Support option in Advanced Setup is set toDisabled. 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 onboardPCI IDE, IRQ9 will still be available for PCI and PnP devices, because at leastone IRQ must be available for PCI and PnP devices. The settings are ISA/EISAor PCI/PnP.

Troubleshooting System Problems

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

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 eight

different 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, andexternal connector type of the PCB (personal computer board) or motherboard.The standard form factors are the AT and ATX, although TYAN also makessome 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 canlock 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 count

down 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 as aunit. 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 order toprevent 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.
