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, itis in your best interest to read an entire section (and perhaps theentire manual) before you begin to fiddle with your motherboard.
While we have alerted you to potential dangers in several places inthe manual with this icon, these warnings should not be regarded asthe whole of your safety regimen. Never forget that computers areelectrical devices, and are capable of delivering a shock. Prevent
damage to yourself and to your board: always ensure that your system isturned off and unplugged whenever you are working with it, and that you areequipped 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 you, you can actually bring your system in to themto have it serviced, instead of attempting to do so yourself (which can haveexpensive consequences).

(1) Ground yourself properly before removing your motherboard from the antistatic bag. Unplug the power from your computer and then touch any metal part on the computer case. (Or wear a grounded wrist strap.)(2) Hold the motherboard by its edges and do not touch the bottom of the board.(3) 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 mother-board out of the cardboard box and static bag, hold it by its edges, and place iton a grounded antistatic surface, component side up. Inspect the board fordamage.
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 antistatic mat). Do not touch the bottomof the board. Remember, don�t take any electronic device out of its protectivebag until you are ready to actually install it into the computer case. If you donot ground yourself, you risk zapping the motherboard or adapter card.Subsequent problems may not arise immediately because electrostatic dis-charge damage, unlike physical damage, causes the device to fail over time.

Quick References for 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. See the Figure 2-1 for examples of�on� and �off� pins and jumpers. The square pin in the diagram is Pin 1.
Jumpers and pins are connected by slipping the blue plastic jumper connectorovertop of two adjacent jumper pins (indicated by 1-2 or 2-3). The metal rodinside the plastic shell bridges the gap between the two pins, completing thecircuit. See Figure 2-2 for more example of pin connections.
Figure 2-1 Figure 2-2
The tables and maps on the following pages will help you set the jumpers forCPU speed, Infrared, and external connector pin assignments, among others.The miniature motherboard maps will help you locate the jumpers on your board.A full-page map of the motherboard can be found on the next two pages.

1-M. Frontside USB Header (J38)Certain computer chassis allow for a front-end USB port connection. There-fore, this board provides a front side USB header should you decide to set upa USB connector at the front side of your computer. Note: If you use J38, youwill be unable to use the TOP USB port at the back of the motherboard. BothJ38 and USB1 share the same channel.
1-N. Boot Block Jumper (JP3)
By default, this jumper is set to the OFF (locked)position. Having the Boot Block protection �locked�will allow system-bootup even if the BIOS bootupfails. In other words, the boot block acts as a backupin case your BIOS fails to boot the system. If thejumper is set to the ON position, this would allow theBoot Block to refresh its BIOS code at the same timeyou flash a new BIOS. Note: If the Boot Block is�unlocked� (jumper ON) and if failure occurs duringa new BIOS Flash, you run the risk of rendering your entire system un-bootable. The �backup� protection of the Boot Block will be lost.
Onboard LED The onboard LED stays �on� when the power supply is plugged in even if themotherboard is turned off. This is due to the suspend to RAM setting in theBIOS (If supported)
Soft Power ConnectorThe Soft Power Connector is part of jumper block J9 (pins 6-8). The Tomcati810 uses the chipset for power management, including turning on and off thesystem. If the Power Button Function option in the BIOS Power ManagementMenu is set to On/Off (which is the default), pressing the power button onceafter the BIOS has booted up will turn the system on and off. If the PowerButton Function option is set to Suspend, pressing the power button once willwake the system or send it to Suspend mode. In this case, you cannot turn thesystem off unless you shut down through the Windows operating system oryou hold the power button down for four seconds.
Hardware Reset Switch Connector InstallationThe 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.
CMOS RTCThe Real Time Clock (RTC) circuit, which provides the date and time for thesystem is integrated into the 810 chipset. If the external battery for the RTC islow, it will prevent your system from POSTing, and you will not get a display.Normally the life span of an external battery is 2 years. If yours is running low,you will need to replace it with a new 3V lithium battery (Sony CR2032).
Flash EEPROMThe Tomcat i810 uses flash memory to store BIOS firmware. It can be updatedas new versions of the BIOS become available. You can upgrade your BIOSeasily using the flash utility (see page 59).
2. Mounting the Motherboard in the Chassis
Follow the instructions provided by the case manufacturer for proper installa-tion guidelines. TYAN recommends that you make use of all mounting holes toscrew down the motherboard. The adapter cards and the screws holding themdown will keep your board flat. The fastening screw should not short any ofthe traces on the motherboard. Make certain that you do not overtighten thescrew, as it will damage the motherboard and possibly break internal traces inthe surrounding area. The hole you should use is located at the top-center ofthe board where the adapter cards are fastened to the case.
3. Installing 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-worldusability. Some cheaper or OEM memory may have brand-name components,but they may contain inferior or substandard parts which do not meet thecritical tolerances our products require. Because of this, your memory may notwork correctly in a TYAN board though it may work well in a competitor�sboard. This is because many of our competitors do not adhere to the stricttolerances required for high performance. If you buy a TYAN board, you are

getting the best system available. To make installation easy and trouble free,get extended memory vendors, please visit Tyan�s website at www.tyan.com -go to the �Memory Support� area in the Support Section. The website memorycompatibility lists include DIMMs that have proven to be very stable on ourboards and perform extremely well.
Figure 2-3*Note: The image above is used to illustrate a concept and may not represent the actualimage of your motherboard.
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 2-3shows 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 2-4 on the next page). Insome cases, pushing the memory module into the DIMM slot will move theplastic clips inward, automatically locking the module into place. To removeyour 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 to avoidstatic damage.

The Tomcat i810 uses a 64-bit data path from memory to CPU and can accom-modate up to 512MB of SDRAM. The 168-pin DIMMs (Dual In-line MemoryModules) must be of the 3.3V, unbuffered variety. The position of the notch inthe SDRAM key position will tell you whether or not a DIMM is unbuffered(see the Figure 2-5 below). All installed memory will be automatically detected,so there is no need to set any jumpers.

4. Installing the CPU and Cooling Fan
Socket 370 type Celeron processors can be used on the Tomcat i810. Remember:
� The CPU is a sensitive electronic component and it can easily be damagedby static electricity. Do not touch the CPU pins with your fingers.
� Before the CPU is installed, the mainboard must be placed on a flatsurface. You should be able to insert the CPU into the socket withminimal, but firm pressure. Do not press down hard on the CPU.

Locate the cooling fan connector (e.g. CPU Fan) 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 willforce you to connect the fan cable correctly (see Figure 2-7 on the previouspage).
5. Connecting IDE and Floppy Drives
The colored stripe on a ribbon cable should face toward the ATX PowerConnector on the motherboard. In Figure 2-8 below, you can see how the IDEcables should look when they are connected to your hard drive. Notice howPin 1 (denoted by a red stripe) is connected so that it is next to the powerconnector of the drive. The primary IDE connector is black; the secondary IDEconnector is white. In most cases, this is the proper way of connecting yourIDE cable to the hard drive.Figure 2-9 on the next page shows the IDE cable properly connected to themotherboard. Contact your hard disk drive manufacturer or documentation formore information.
ATA-66 IDE hard drives require a special 80 pin IDE cable which has additionalgrounding wires. The cable is included and is required when using ATA-66drives, this cable will also support all legacy IDE drives.

Some symptoms of incor-rectly installed HDDs are:� Hard disk drives are
not auto-detected: maybe a Master/Slaveproblem or a bad IDEcable. Contact yourvendor.
� Hard Disk Drive Failmessage at bootup:may be a bad cable orlack of power goingto the drive.
� No video or beeps onbootup: usually meansthe cable is on backwards.
� Hard drive lights areconstantly on: usuallymeans bad IDE cable or defective drives/motherboard. Try another HDD.
� Hard drives do not power up: check power cables and cabling. May alsobe a bad power supply or IDE drive.
Connecting Floppy DrivesPin 1 on the floppy cable is usually denoted by a red or colored stripe downone side of the cable (see Figure 2-10 below). Most of the current floppydrives on the market require that the colored stripe be positioned so that it is
Figure 2-10

right 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: isusually connected to the middle of the cable. Refer to your installation instruc-tions or call your dealer if you are unsure about attaching floppy drives. Refer toFigure 2-10 for a detailed anatomy of the floppy cable. Remember, you can onlyhave 2 floppy drives connected at any given time.
The color stripe on the cable should face toward the ATX Power Connector onthe motherboard.
Some symptoms of incorrectly installed floppies are:� Floppy drives are not detected: usually caused by faulty cables, backward
cables, or a bad floppy or motherboard. Try another single floppy drive 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 motherboard maybe faulty. Try another cable or floppy drive to verify.
� Light on the floppy is on constantly: a dead giveaway that the cable is onbackwards. Reverse the cable at the motherboard end and try again.
6. Installing Add-on Cards
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 4 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 of

the card into the socket first and then the other. This will create arocking 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
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 install thecomponents right, the first time.
7. Connecting PS/2, USB, Serial & Parallel Devices
This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices. Notethat, for this board, the mouse port is the upper PS/2 port, and the keyboard portis the lower PS/2 port.
Figure 2-13
The PS/2 connectors are probably quite familiar to you. The USB connectors,however, may be foreign. The USB (Universal Serial Bus) is a versatile port. Thisone port type can function as a serial, parallel, mouse, keyboard, or joystick port.It is fast enough to support video transfer, and is capable of supporting up to 127daisy-chained peripheral devices. Figure 2-13 above shows the ATX double rowconnectors on this board. The Com and Printer ports, as well as the other ports,are labeled.
Connecting Com and Printer PortsWarning: When plugging in your keyboard and mouse, or when plugginganything into a serial or Com port, make sure that the power is off. Connectingthese devices and ports while the power is on is called �hot plugging,� andmay damage your system.Note: Only TYAN cables will work on this motherboard. If you are using anexisting case with old cables, your system will not function properly. Use onlyTYAN-approved cables.
8. Connecting the Power Supply
The Tomcat i810 requires an ATX power supply. Tyan recommends using onethat conforms to industry standard revision 2.01. The photos on the next pageshow the ATX power connector before (Figure 2-11) and after (Figure 2-12) ithas been plugged in. The plastic clip on the power connector should lock overthe plastic tab on the onboard connector. You shouldn�t be able to plug thepower connector in any other way but just to be safe, make sure it looks likeFigure 2-12.

Chapter 2Onboard Resource Settings
Make certain that you do not miss any pins because if you do, you will voidyour warranty and cause damage to yourself or your motherboard when youturn the system on. After connecting the power, make sure the connector isseated firmly into its socket so it will not become loose or fall off when thecomputer is jostled or moved.
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 7).
Frequently Asked Questions
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: Where can I get USB cables for my motherboard?A: You can get USB cables from www.wiretek.com Tyan USB Cable Part # :S1606-001-01
Q: What is the USB pin out information for Tyan motherboards?A: Please refer to URL link here: http://www.tyan.com/support/html/usb.html
Q: My motherboard is dead, how do I return it?A: Contact the place of purchase or your distributor for assistance to returnthe motherboard for service.

OffBoard PCI IDE Primary IRQThis option specifies the PCI interrupt used by the primary IDE channel on theoffboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,INTB, INTC, or INTD.
Offboard PCI IDE Secondary IRQThis option specifies the PCI interrupt used by the secondary IDE channel onthe offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,INTB, INTC, or INTD.
PCI Slot n IRQ PriorityThese options specify the IRQ priority for PCI devices installed in the PCIdevices installed in the PCI expansion slots. The settings are Auto, IRQ 3, 4, 5,7, 9, 10, and 11, in priority order.
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. These optionsdetermine if AMIBIOS should remove an IRQ from the pool of available IRQspassed to devices that are configurable by the system BIOS. The available IRQpool is determined by reading the ESCD NVRAM. If more IRQs must beremoved from the pool, you can use these options to reserve the IRQ byassigning an ISA/EISA setting to it. Onboard I/O is configured by AMIBIOS.All IRQs used by onboard I/O are configured as PCI/PnP. IRQ12 only appearsif the Mouse Support option in Advanced Setup is set to Disabled. IRQ14 and15 will not be available if the onboard PCI IDE is enabled. If all IRQs are set toISA/EISA and IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ9 willstill be available for PCI and PnP devices, because at least one IRQ must beavailable for PCI and PnP devices. The settings are ISA/EISA or PCI/PnP.
Reserved Memory Size This option specifies the size of the memory area reserved for legacy ISAadapter cards. The settings are Disabled, 16K, 32K, or 64K.
Reserved Memory AddressThis option specifies the beginning address (in hex) of the reserved memoryarea. The specified ROM memory area is reserved for use by legacy ISAadapter cards. This option does not appear if the Reserved Memory Sizeoption is set to Disabled. The settings are C0000, C4000, C8000, CC000, D0000,D4000, D8000, or DC000.

Flash Writer Utility
The AMI Flash Writer Utility is now included in the AMIBIOS, and so it issimpler to upgrade the BIOS of your mainboard. The system BIOS is stored ona flash EEPROM ROM chip on the mainboard which can be erased andreprogrammed by following the directions on the following page.1. From the DOS prompt, rename the BIOS file that you have downloaded to�amiboot.rom� and copy it on to a floppy disk.2. Insert the floppy disk with the BIOS upgrade into the A: drive.3. Turn the power off.4. While holding the <Ctrl> and <Home> keys, turn the power on. The systemwill begin to read from the A: drive, and write the BIOS information containedon the floppy disk in that drive to the EEPROM ROM chip. When the BIOShas been totally reprogrammed, the system will reboot with the new BIOS inoperation.5. If the system does not reboot in three minutes, power down the system waita few seconds, and then turn the power back on again. You will be prompted topress <F1> to run Setup. You may check your settings at this time, or simplysave and exit the program.

Beep Codes
Fatal errors, which halt the boot process, are communicated through a series ofaudible beeps. If AMIBIOS POST can initialize the system video display, itdisplays the error message. Displayed error messages, in most cases, allow thesystem to continue to boot. Displayed error messages are described on pages62-63. See the top of the next page for 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... for 5 or 7 beeps, first test with a new CPU - if thatdoes not solve the problem, then motherboard mustbe replaced.
ACPI (Advanced Configuration and Power Interface) is a power managementspecification that allows the operating system to control the amount of powerdistributed to the computer�s devices. Devices not in use can be turned off,reducing unnecessary power expenditure.
AGP (Accelerated Graphics Port) is a PCI-based interface which was designedspecifically for demands of 3D graphics applications. The 32-bit AGP channeldirectly links the graphics controller to the main memory. While the channelruns at only 66MHz, it supports data transmission during both the rising andfalling ends of the clock cycle, yielding an effective speed of 133MHz.
AMR (Audio Modem Riser) is a modem that can be used on Intel ReferenceMotherboard platforms using Intel�s core logic chipsets supporting AC-Link2.1 It supports fax and all data feeback modes. It provides high speedcommunicstions between your perosn al computer and a remote location, suchas an Internet Service Provider (ISP)
AT was the original form factor of IBM�s PC.
ATAPI (AT Attachment Packet Interface), also known as IDE or ATA, is a driveimplementation that includes the disk controller on the device itself. It allowsCD-ROMs and tape drives to be configured as master or slave devices, justlike hard drives.

ATX form factor was designed to replace the AT form factor. It improves onthe AT design by rotating the board ninety degrees, so that the IDE connec-tors are closer to the drive bays, and the CPU is closer to the power supplyand cooling fan. The keyboard, mouse, serial, USB, and parallel ports are builtin.Bandwidth refers to carrying capacity. The greater the bandwidth, the moredata the bus, phone line, or other electrical path, can carry. Greater bandwidth,then, also results in greater speed.
A BBS (Bulletin Board System) is a computer system with a number 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, andprovides the basic instructions for controlling your computer�s hardware. Boththe operating system and application software use BIOS routines to ensurecompatibility.
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 connectionbetween the processor and system memory, and between the processor andPCI 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 needed informa-tion is stored in the SRAM instead of in the slower DRAM. Note that thecache is also much smaller than your regular memory: a typical cache size is512KB, 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 memory

which 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 of 512MB.In this case, up to 512MB of the main memory onboard is capable of beingcached. However, only 512KB of this memory will be in the cache at any givenmoment. Any main memory above 512MB could never be cached.
Closed and open jumpers Jumpers and jumper pins are active when they areOn or Closed, and inactive when they are Off or Open.
CMOS Complementary Metal-Oxide Semiconductors are chips that hold thebasic start-up information for the BIOS.
The COM port is another name for the serial port, which is so-called because ittransmits the eight bits of a byte of data along one wire, and receives data onanother single wire (that is, the data is transmitted in serial form, one bit afteranother). Parallel ports transmit the bits of a byte on eight different wires at thesame time (that is, in parallel form, eight bits at the same time).
DIMM Dual In-line Memory Modules are a faster and more capacious form ofRAM than SIMMs, and do not need to be installed in pairs.
DIMM bank DIMM banks are sometimes called DIMM sockets, because thephysical slot and the logical unit are the same. That is, one DIMM module fitsinto one DIMM socket, which is capable of acting as a memory bank.
DMA Direct Memory Access channels are similar to IRQs. DMA channels allowhardware devices (like sound cards or keyboards) to access the main memorywithout involving the CPU. This frees up CPU resources for other tasks. Aswith IRQs, it is vital that you do not double up devices on a single line. Plugand 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 regularly(every few milliseconds). This refresh requirement makes DRAM three to tentimes slower than non-recharged RAM such as SRAM.
EDO RAM (Extended Data-Out RAM) speeds access to memory locations byassuming that memory addresses are static: the next time it looks for a bit ofdata, it will be at the same spot, or one nearby.

EEPROM Electrically Erasable Programmable ROM, also called Flash BIOS, isa ROM chip which can, unlike normal ROM, be updated. This allows you tokeep up with changes in the BIOS programs without having to buy 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 Time Clock.
Handshaking is a form of encryption. One system, typically the server, sendsan encryption scheme to another agent, typically a client. Thus, the client�sdata is protected during transmittal to the server.
HDD stands for Hard Disk Drive.
H-SYNC controls the horizontal properties of the monitor.
IC (Integrated Circuit) is the formal name for the computer chip.
IDE Integrated Device (or Drive) Electronics is a simple, self-contained harddrive interface. It can handle drives up to 8.4GB in size. Almost all IDEs soldnow are in fact Enhanced IDEs (EIDEs).
IDE INT (IDE Interrupt) is a hardware interrupt signal that goes to the IDE.
I/O Input/Output is the connection between your computer and another pieceof hardware (mouse, keyboard, etc.).
IRQ An Interrupt Request is an electronic request that runs from a hardwaredevice to the CPU. The interrupt controller assigns priorities to incomingrequests and delivers them to the CPU. It is important that there is only onedevice hooked up to each IRQ line; doubling up devices on IRQ lines can lock

up your system. Happily, Plug and Play operating systems take care of thesedetails 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, memorythat holds its data without power. DRAM, in contrast, is volatile.
OEMs (Original Equipment Manufacturers) like Compaq or IBM package othercompanies� motherboards and hardware inside their case and sell them.
The parallel port transmits the bits of a byte on eight different wires at thesame 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 data transfermodes used by IDE drives. These modes use the CPU for data transfer (DMAchannels do not). PCI refers to the type of bus used by these modes tocommunicate with the CPU.
PCI-to-PCI bridge allows you to connect multiple PCI devices onto one PCIslot.
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 downthe number of seconds or minutes until the system times out and enters sleep,suspend, or doze mode.
PnP is an acronym for Plug and Play, a design standard that has 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 to work.Devices and operating systems that are not Plug and Play require you toreconfigure your system each time you add or change any part of yourhardware.
The term RAM (Random Access Memory), while technically referring to a typeof memory where any byte can be accessed without touching the adjacentdata, is often used to refer to the system�s main memory. This memory isavailable to any program running on the computer.
ROM (Read-Only Memory) is a storage chip which contains the BIOS (BasicInput/Output System), the basic instructions required to boot the computerand start up the operating system.
SDRAM (Synchronous Dynamic RAM) is so-called because it can keep twosets of memory addresses open simultaneously. By transferring data alter-nately from one set of addresses, and then the other, SDRAM cuts down onthe 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 of dataalong one wire, and receives data on another single wire (that is, the data istransmitted 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 you stickSIMM modules. A pair of SIMM sockets form a SIMM bank, and act as a unit.If only one socket is filled, the bank will not operate.
In Sleep/Suspend mode, all devices except the CPU shut down.

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 other devicesoperate normally.
UltraDMA/66 is a fast version of the old DMA channel. UltraDMA is alsocalled UltraATA. Without UltraDMA your system cannot take advantage ofthe 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 open ZIFsocket, and the metal lever pulled down. This shifts the processor over anddown, guiding it into place on the board.
