Chapter 2: Board Installation

2.1 Installation

Once you’ve checked th at everything is ins ide the box (see p. 4 for details), you will then be ready to install your mothe rboard . The m ounti ng ho le patt ern o f the m other board match es t he ATX board specif ications, so your chassis must be capable of suppor ting an Extended ATX board (check the mo therbo ard dimensions provided on p. 7).

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

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

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

2.3 Here are some safety tips:

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

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

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

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

http://www.tyan.com

2.4 Quick References for Jumpers

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

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

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

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

2.6-J. Soft Power Connector

The soft power connector is part of jumper block J15 (pins 6 and 8). This board uses the chipset for power management, including tur ning on and off the system. If the power b utton function option in the BIOS Power Management me nu is set to “On/Off” (wh ich is the d efault), pr essing the p ower button once after the BIOS has booted up will turn the system on a nd off. If the power button functio n is set to Suspend, pressing the power button once will wake up t he system or send it to Suspend mode. In this case, you cannot turn the system off unless yo u shut d own through the Windo ws oper ating system o r you ho ld the power button down for four seconds (BIOS-dependent feature).

2.6-K. Hardware Reset Switch Connector Installation

The reset switch on your chassis case provides you with the Hardware Reset function, which is the same as power on/off, except that the system will immediately execute a cold start afte r the reset button is pushed. The reset switch needs to be connected to jumper block J15 (pins 5 and 7).

2.7 Mounting the Motherboard into the Chassis

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

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

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

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

2.8 Installing Memory

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

Here are some details of memory installation for this board:

At least one non-registered, unbuffered DIMM must be installed in order to POST.

Supports 128MB, 256MB, 512MB* non-registered, unbuffered DIMMs ONLY.

PC100 supported in a three DIMM setup. PC133 only supported in a two DIMM setup.

The motherboard supports up to 512MB* of PC100/133 SDRAM.

Memory Installation Procedure

Step

* Please check Tyan website for memory compatibility information: http://www.tyan.com

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

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

short row of pins long row of pins

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

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

Tomcat i815T S2080

Step

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

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

Removing a DIMM

Removing a DIMM is ju st the r everse: pull ba ck the cli ps from the D IMM (s ee pictu res be low), an d carefully pull the module st raight out. Place the D IMMs in a n anti-static bag as soon as you r emove them to avoid static damage.

Unbuffered and Non-Registered vs. Registered Memory

The 168-pin DIM Ms (Du al I n-li n e M em or y M odu l es) m ust be of the 3.3V PC100/PC133 unb uf fe re d variety. The notch position in the SDRAM key position will tell you whether or not a DIM M is unbuffered (see

Figure 2.1 below). All installed memory will be auto-detected, so there is no need to set any jumpers.

2.9 Installing the CPU and Cooling Fan

Intel Pentium II proce ssor s up t o 1. 13+GHz and Intel Celerons u p to 800 MHz can be used on this board. For more information on CPU compatibility, check Tyan’s website at: http://www.tyan.com.

When installing your CPU, remember the following:

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

Do not touch the CPU pins with your fingers

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

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

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

Installing the CPU

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

Step

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

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

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

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

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

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

http://www.tyan.com

Installing the Cooling Fan(s)

After a CPU has been installed, you will need to install the prop er cooling d evice for the CPU. This device, a heatsink/fan com bination , can be purc hased at ma ny compute r retail store s. Installat ion of the cooling device may vary depe nding on the fan manufacturer ’s design. You should also take space into consideration when in stall a c ooli n g d evice : m ake su re th e cooling device is no t to o big, or e l se y ou ma y end up damaging components around the CPU socket.

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

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

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

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

Connecting Floppy Drives

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

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

2.11 Installing Add-on Cards

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

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

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

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

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

board if you do this.

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

Make sure the cards are seated securely into their slots.

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

Check the PCI device specifications with the PCI slot specifications (p.6) BEFORE installing!

When installing the add-on cards, make sure the cards are installed with even force; do not insert one end and then the other. See the before (Figure 2.2a) and after (Figure 2.2b) example in sta l la t i on i ma g es

below for details.

Check orientation of card when installing

2.12 Connecting PS/2, USB, and Serial Devices

This motherboard includes ports for PS/2 mouse and keyboard, Universal Serial Bus (USB) devices, and serial and parallel devices. Please note that the upper PS/2 port is the mouse port, and the lower PS/2 port is for the keyboard (see Figure 2.3 below).

Installation of peripheral/external devices may vary. For details on installation of devices into the various ports shown below, please consult your device’s documentation, device manufacturer, or your dealer for details.

Connecting Serial and Parallel Ports

The serial and parallel ports can be used to connect various devices such as a mouse or printer. The connectors can only be connected one way: be sure and check the orientation of the connector before installing it into the port.

When plugging in y our keyboa rd an d mou se, or when plug ging i n any thing i nto a serial or parallel port, make sure that the power is off. Connecting these devices and ports while the power is on is called hot plugging and may damage your system and/or external devices that you are trying to install.

* Indicates an optional feature available on some Tomcat i815T models

Tomcat i815T S2080

2.13 Connecting the power supply

This motherboard requires an ATX power supply, one that conforms to ATX standard 2.01 or better.

The clip on the power connector should lock over the tab on the onboard connector. Y ou shouldn’t be able to plug the power connector in any other way but just to be safe, make sure it looks like Figure 2.4b. Make certain that you do not miss connecting any of the pins because if you do, you will void your warranty and possibly cause damage to yourself and/or your motherboard when the power is turned 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.

Shown on the right, in Figure 2.4a, is

2.15 Frequently Asked Questions (FAQ)

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

A: The first thing to do is to check and see if you have any device conflicts related to the IRQ, or DMA. If you are using Microsoft Windows, the Control Panel is a good place to start investigating the conflict. Please consult your operating system documentation for details. Secondly, slowing down the memory timing in the BIOS’ chipset setup section might help the situation as well. Many memory modules are not suitable for high performance systems and might be the main source of your problem. Also check to make sure you are using a power supply that that confirms to ATX 2.01 or better. Lastly, make sure the motherboard is receiving adequete cooling.

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

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

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

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

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

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

Q: How do I upgrade my BIOS?

A: Check the section about the Flash Utility (see p. 47) for information on upgrading your BIOS. BIOS update files, flash utilities, and instructions on how to install them are also available from the Tyan website at: http://www.tyan.com

Q: Why do I get a “CMOS checksum invalid” er ror message during POST?

A: If you get the above error message or “Invalid configuration, run Setup” message, it is an indication that the CMOS battery needs to be changed. Contact your dealer for assistance. Once you’ve replaced your battery or flashed your BIOS, don’t forget to check the Clear CMOS section (see p.11) so that you can reset your CMOS.

* If your chassis supports frontside USB connectors, it will usually come with the necessary cables. Check that your chassis is frontside USB capable. Please check with your chassis vendor for details.

Chapter 3: BIOS Setup

Introduction to the BIOS setup

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

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

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

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

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

Starting Setup

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

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

Not all systems have the same setup program. While th e basic look and functio n of the setup program remains more or le ss th e sam e f or all sy stem s, t he ap pea ran c e of your Setup screen may differ fr om the screens shown here. Each sy stem design and chipset combination requ ire custom configurations. In addition, the fina l appearance of the setup pr ogram depends on your system designer. Your system designer can decide tha t certain item s should not be available for use r configurati on, and remove t hem from the BIOS setup program.

Chapter 4: System Resources

Note: If you experience problems with setting up your system, always check the following things in the

following order:

MEMORY, VIDEO, CPU

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

4.1 Beep Codes

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

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

4.2 Flash Utility

Every BIOS file is unique for the motherboard it was designed for. For Flash Utilities, BIOS downloads, and information on how to properly use the Flash Utility with your motherboard, you must check the Tyan website: http://www.tyan.com

Please be aware that by flash ing your BIOS, you a gree that in the eve nt of a BIOS flash failure, you must contact your dealer fo r a replacement BIOS. T here are no

Appendix II: Glossary

ACPI (Advanced Configuration an d Power Interface): a pow er m anage ment s pecific ation th at al lows 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 (A

ccelerated Graphics Port): a PCI-base d inte rfa ce whic h was de sign ed spe ci fical ly for dem and s of 3D graphics applications. Th e 32-bi t AGP chann el directl y links the grap hics con troller to the main memory. While the channel runs at only 66 MHz, it supports data transmission during both the rising and falling ends of the clock cycle, yielding an effective speed of 133 MHz.

ATAPI (AT the disk controller on the dev ice itsel f. It all ows CD -ROMs an d tape dr ives to be co nfigure d as maste r or slave devices, just like HDDs.

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

Bandwidth: refers to carrying cap aci ty. The greater the ban dw idt h, th e m ore dat a the bus, phone line, or other electrical path, can carry. Greater bandwidth, then, also results in greater speed.

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

BIOS (B instructions for controlling your computer’s hardware. Both the operating system and application software use BIOS routines to ensure compatibility.

Buffer: a portion of RAM which is u sed to te mp ora ril y sto re d ata , usu all y fr om an a pplic a tion , tho ugh i t is also used when printing, and in most keyboard dr ivers. The CPU can manipulat e data in a buffer before copying it, all at once, to a disk drive. While this improves syst em performance --- readin g to or writing from a disk drive a single time is much fa ster than doing so repeatedly --- there is also the possi bility of losing your data should the system cr ash. Inf ormatio n sto re d in a bu ffer is te mp orarily st ore d, n ot p ermanently saved.

Attachment Packet Interface): also known as IDE or ATA; a drive implementation that includes

IOS Boot Specification): is a feature within the BIOS th at creates, p rioritizes , and m aintains a list

asic Input/Output System): the program that resides in the ROM chip, an d provides the basic

Bus: a data pathway. The term is used especially t o refer to the connec tion bet ween the pr ocessor and system memory, and between the processor and PCI or ISA local buses.

Tomcat i815T S2080

Bus mastering: allows peripheral devices and IDEs to access the system memory without going through

the CPU (similar to DMA channels).

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

Cache size: refers to the physical size of the cache onboard. This should not be confused with the cacheable area, which is the total amoun t of m emory wh ich ca n be sc anned by the syste m in se arch of da ta to put into the cache. A ty pical setup would b e a ca che si ze o f 512KB , an d a ca cheable area of 5 12MB. In this case, up to 512KB of the main memory onboard is capable of being cached. However, only 512KB of this memory will be in the cache at any given moment. Any main memory above 512MB could never be cached.

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

CMOS (C the BIOS.

COM port: another name fo r t he seri a l po rt, whi ch is ca l led as su ch beca use i t tr an smits the eig ht b i ts o f a byte of data along one w ire , an d re cei ve s da ta on another single wire ( tha t i s, th e da ta is t ran smitted in serial form, one bit after another) . Parallel ports tran smit the bits of a byte on eight different w ires at the same time (that is, in parallel form, eight bits at the same time).

DDR (D output on both the rising and falling edge of th e system clock rather than on just the rising ed ge, potentially doubling output.

DIMM (D need to be installed in pairs.

DIMM bank: sometim es called DIMM sockets, because the physical slot and th e logical unit are the same. That is, one DIMM module fits into one DI MM socket, which is capable o f acting as a memory bank.

DMA (D (like soundcards or keyboards) to access the main memory without involving the CPU. This frees up CPU resources for other tasks. As with IRQs, it is vital that you do not double up devices on a single line. Plugn-Play devices will take care of this for you.

Doze mode: in this mode, only the CPU’s speed is slowed.

omplementary Metal-Oxide Semiconductors): chips that hold the basic startup information for

http://www.tyan.com

DRAM (Dynamic RAM): wide ly available, very afford able form of RAM whi ch has the unfortunate tendency to lose data if it is not recharged regularly (every few milliseconds). This refresh requirement makes DRAM three to ten times slower than non-recharged RAM such as SRAM.

ECC (E

rror Correction Code or Error Checking and Correcting): al lows da ta to be chec ked fo r er ror s

during run-time. Errors can subsequently be corrected at the same time that they’re found.

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

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

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

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

Form factor: an i nd ust ry t erm fo r the size, sh ape , p ow er su ppl y typ e, a nd ext ern al c onn ecto r type of the

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

Global timer: onboard hardware timer, such as the Real-Time Clock (RTC).

Handshaking: a form of encryption. One system, typically th e server, sends an encryption scheme to

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

HDD: stands for H

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

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

xtended System Configuration Data): a format fo r stori ng infor ma tion a bou t P lug- n-Pl a y device s

ntegrate d Circuit): the formal name for the computer chip.

IC (I

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

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

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

I/O (I

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

board, etc.)

Tomcat i815T S2080

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

capable of loading and execu ting an OS, as w ell as being able to pro vide control ba ck to the B IOS if the loading attempt fails.

IPL: see Initial Program Load.

IRQ (Interrupt Request): an electronic request that runs from a hardware device to the CPU. The interrupt

controller assigns priorities to incoming requests and delivers them to the CPU. It is important that there is only one device hooked up t o each IRQ line; d oubling u p devices o n IRQ lin es can lock u p your sys tem. Plug-n-Play operating systems can take care of these details for you.

ISA (I

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

Latency: the amount of time that one part of a system spends waiting for another part to catch up. This is most common when the syste m s end s da ta o ut t o a per iphe ra l device, and it waiting for the p erip her al to send some data back (peripherals tend to be slower than onboard system components).

Mirroring: see RAID.

NVRAM: ROM and EEPROM are both examples of Non-Volatile RAM, memory that holds its data without

power. DRAM, in contrast, is volatile.

OEMs (O and hardware inside their case and sell them.

Parallel port: transmits the bits of a byte on eight different wires at the same time (that is, in parallel form, eight bits at the same time).

PCI (P ISA bus. Local buses are those which operate within a single system (as opposed to a network bus, which connects multiple systems).

PCI PIO (PCI P modes use the C PU for dat a transfer ( in contrast, D MA channel s do not). PCI refers to the type of bus used by these modes to communicate with the CPU.

PCI-to-PCI bridge: allows you to connect multiple PCI devices onto one PCI slot.

Pipeline burst SRAM: a fast secondary cache. It is used as a secondary cache because SRAM is slower

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

riginal Equipm ent Manufacturers): Compaq or IBM package other companies’ mother boards

eripheral Component Interconnect): a 32 or 64-bit local bus (data pathway) which is faster than the

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

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

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

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

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

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

ower Management time rs) : software timers that count dow n the number of se conds or min-

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

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

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

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

ROM (R

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

boot the computer and start up the operating system.

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

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

Tomcat i815T S2080

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

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

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

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

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

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

Standby mode: in this mode, the video and fixed disk drive (usually the HDD) shuts down; all other devices continue to operate normally.

Striping: see RAID.

UltraDMA/33/66/100: a fast version of the old DMA channel. UltraDMA is also called UltraATA. Without

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

USB (U

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