Introduction

Overview

The S1834 Tiger 133 is a quality , high performance motherboard designed for dual Intel PII / PIII microprocessors. The Tiger 133 utilizes the VIA Apollo Pro 133A chipset (VT82C694X) with A ward BIOS. The S1834 can support CPU speeds of 450MHz through 800+MHz, and host bus speeds of 100 MHz to 133 MHz (the VIA chipset’s bus speed is Auto-Determined by the CPU). The S1834 motherboard, with built-in 4x AGP slot, provides high performance capabilities that are ideal for a wide range of demanding applications such as CAD, CAM, CAE, desktop publishing, 3D animation, 3D Games and video production.

This system board in an ATX form factor offers far more features and expandability than other ATX models. Some of the features included are onboard dual channel PCI PIO, Bus Master IDE and UltraDMA/66, onboard floppy controller, and onboard high speed I/O, PC133 SDRAM support, and V irtual Channel Memory SDRAM support.

Flexibility and expandability have been designed into the Tiger 133. W ith I/O and drive controller support built onboard, the one AGP slot plus six PCI gives a total of seven usable slots for numerous add-on expansion cards.

Introduction

Technical Support

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

Help resources:

1. See FAQ and beep codes sections of this manual.

2. See T yan web site for FAQ, bulletins, driver updates, etc.

http://www.tyan.com

3. Contact your dealer or distributor for help BEFORE calling T yan.

4. Check the T yan user group: alt.comp.periphs.mainboard.tyan

Returning Merchandise for Service

During the warranty period, contact your distributor or system vendor FIRST for any product problems. This warranty only covers normal customer use and does not cover damages incurred during shipping or failure due to the alteration, misuse, abuse, or improper maintenance of products.

For Resellers Only:

A receipt or copy of your invoice marked with the date of purchase is required before any warranty service can be rendered. You can obtain service by calling the manufacturer for a Return Merchandise Authorization (RMA) number. The RMA number should be prominently displayed on the outside of the shipping carton and the package should be mailed prepaid, or hand-carried to the manufacturer. TYAN will pay to have the board shipped back to you.

Unpacking

The motherboard package should contain the following: (1 ) S1834 mainboard (1 ) 34-pin floppy cable pack (1) 80-pin A T A-66 IDE cable (1 ) S1834 User’s Manual (1 ) Driver CD (2) URM Retention Modules

(T erminator card is currently not needed on this board when using only a single processor . Check http://www .tyan.com for information and updates concerning CPUs.)

Installation

You are now ready to install your motherboard. The mounting hole pattern of the S1834 matches the ATX system board specifications. Your chassis should support a standard ATX mainboard form factor.

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.

Here are some precautions you should follow when installing your mother-

board:

(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) A void 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, component side up. Inspect the board for damage.

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

important!

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

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 to jumpers (or jumper pins) that are inactive. See the Figure 2-1 for examples of “on” and “off” pins and jumpers.

Jumpers and pins are connected by slipping the plastic jumper connector overtop of two adjacent jumper pins (indicated by 1-2 or 2-3). The metal rod inside the plastic shell bridges the gap between the two pins, completing the circuit. See Figure 2-2 for more example of pin connections.

1-F . Soft Power Connector

The Soft Power Connector is part of jumper block J10. The Tiger 133 uses the chipset for power management, including turning on and off the system. If the Power Button Function option in the BIOS Power Management Menu is set to On/Off (which is the default), pressing the power button once after the BIOS has booted up will turn the system on and off. If the Power Button Function option is set to Suspend, pressing the power button once will wake the system or send it to Suspend mode. In this case, you cannot turn the system off unless you shut down through the Windows operating system or you hold the power button down for four seconds.

1-G. Hardware Reset Switch Connector Installation

The Reset switch on your case’s display panel provides you with the Hardware Reset function, which is the same as power on/off. The system will do a cold start after the Reset button is pushed. (J10 pin 5 & 7 for example).

1-H. Chassis Intrusion Alarm Connector (JP14)

The JP14 connector is an intrusion alarm that can be connected to the system chassis. When active (JP14 is connected to the chassis), this alarm will alert the system administrator anytime someone opens the system’s case.

1-I. Power LED Connector

Refer to panel connector J10 for 2 pin LEDs. 3 pin LED’s can still be used on J10 where pin 13 would be for the Ground pin.

CMOS RTC

(Clr CMOS)

The Real Time Clock (R TC) circuit, which provides the date and time for the system is integrated into the Via Apollo Pro Plus 133A AGPset. If the external battery for the RTC is low, it will prevent your system from POSTing, and you will not get a display. Normally the life span of an external battery is 2 years. If yours is running low , you will need to replace it with a new 3V lithium battery (Sony CR2032).

Flash EEPROM

The Tiger 133 uses flash memory to store BIOS firmware. It can be updated as new versions of the BIOS become available. Y ou can upgrade your BIOS easily using the flash utility (see page 59).

2. Mounting the Motherboard in the Chassis

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

3. Installing Memory

Since TYAN boards are manufactured with performance in mind, you should use add-in components that match. It is highly recommended that the memory DIMMs are installed prior to connecting the power supply . Some DIMM

modules may seem to be high quality because of name or feel but that does not

guarantee real-world usability . Some cheaper or OEM memory may have brandname components, but they may contain inferior or substandard parts which do not meet the critical tolerances our products require. Because of this, your memory may not work correctly in a TY AN board though it may work well in a competitor’s board. This is because many of our competitors do not adhere to the strict tolerances required for high performance. If you buy a TYAN board, you are getting the best system available. To make installation easy and trouble free, get high quality parts. Some brands we recommend are Advantage Memory , Corsair Microsystems, Millenium, Kingston Memory, QesT ec Incorporated, Unigen, Micron T echnology, and Crucial T echnology. These DIMMs have proven to be very stable on our boards and perform extremely well. Please check the TY AN website for more information and updates about memory compatibility: www .tyan.com

warning

Because of this, you need to UNPLUG the AC power cord before installing your DIMM memory modules. Otherwise, the motherboard may automatically power up when the memory is inserted into the slot.

Figure 2-5*

*Note: The image above is used to illustrate a concept and may not represent the actual

image of your motherboard.

T o install your DIMMs, line your module up so that the pins fit into the slot. There is only one way that your DIMM can fit properly. Make sure that the short row of pins is lined up with the short gap in the DIMM slot. Figure 2-5 shows how to sit the DIMM into its slot. To insert the DIMM, push down vertically on the module with even force, as shown in the photo. Do not shove one end in first; doing so will bend the DIMM pins.

T o lock the DIMM into place, push the plastic clips on either end of the slot onto the notches in the ends of the DIMM (see Figure 2-6 on the next page). T o remove your DIMM, simply pull the clips back, and pull up on the module.

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

The Tiger 133 uses a 64-bit data path from memory to CPU and can accommodate up to 2 GB of PC100 SDRAM and up to 1.5GB of PC133 SDRAM. The 168-pin DIMMs (Dual In-line Memory Modules) must be of the 3.3V, unbuffered, non-ECC variety . The position of the notch in the SDRAM key position will tell you whether or not a DIMM is unbuffered (see the Figure 2-7 below). All installed memory will be automatically detected, so there is no need to set any jumpers.

4. Installing the CPU and Cooling Fan

Slot 1 type Pentium II/III can be used on the Tiger 133. Please refer to page 15 for the correct CPU jumper settings for your CPU. 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. You should be able to insert the CPU into the slot with very little force. Do not press down hard on the CPU as you will bend or break pins and possibly damage your motherboard.

• After the CPU is securely seated, install the appropriate cooling device.

T yan strongly recommends a heatsink/fan combination. Consult with your case manufacturer for other cooling options.

Installing Slot1 T ype CPUs

Using a cooling mechanism for processors is extremely important. The active cooler shown in Figure 2-9 below is equipped with a cooling fan and heat sink, allowing better air flow and heat dissipation for the CPU. The size of the cooling mechanism will not interfere with CPU installation. The CPU will fit with ease into the CPU slot of the Tiger 133 board.

Board Installation

Figure 2-10 below shows an overhead view of the retention braces positioned at both ends of the CPU slot. Be sure to tighten the retention brace screws to secure them onto the motherboard.

Figure 2-10*

Carefully line up the pins of the CPU with the pins of the Slot while placing the CPU between the two retention braces (the CPU cooling fan should face the memory DIMM sockets). Lower the CPU onto the motherboard (see Figure 210 below). Y our CPU will be firmly secured onto the motherboard once the retention braces “snap” into the sides of the CPU. The installed CPU should look like Figure 2-12 on the following page.

Note: The retention module shown above may not represent the one provided with your motherboard.

You will also need to connect the CPU’s cooling fan cable to the cooling fan power connector on the board. Locate the cooling fan connector (e.g. FAN1) on the motherboard. Plug the CPU’s cooling fan cable into the cooling fan connector on the board. There will be a plastic clip assembly similar to that of the ATX power connector that will force you to connect the fan cable correctly see Figure 2-13 below.

Removing CPU

T o remove the CPU, gently bend the sides of the retention brace away from the CPU and slowly pull the CPU upwards. This may require careful firm tugs to pull the CPU out of its slot.

5. Connecting IDE and Floppy Drives

The colored stripe on a ribbon cable should connect to Pin 1 The primary IDE connector is black; the secondary IDE connector is white. In most cases, this is the proper way of connecting your IDE cable to the hard drive. Figure 2-14 below shows the IDE cable properly connected to the motherboard. Contact your hard disk drive manufacturer or documentation for more information.

Some symptoms of incorrectly installed HDDs are:

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

problem or a bad IDE cable. Contact your vendor.

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

lack of power going to the drive.

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

wards.

• Hard drive lights are constantly on: bad IDE cable or defective drives/ motherboard. Try another HDD.

• Hard drives do not power up: check power cables and cabling. May also be a bad power supply or IDE drive.

Pin 1 on the floppy cable is usually denoted by a red or colored stripe down one side of the cable (see Figure 2-15). Most of the current floppy drives on the market require that the colored stripe be positioned so that it is right next to the power connector. In most cases, there will be a key pin on the cable which will force you to connect the cable properly.

Figure 2-15

Drive A: is usually attached to the end of the cable with the twist in it. Drive B: is usually connected to the middle of the cable. Refer to your installation instructions or call your dealer if you are unsure about attaching floppy drives. Refer to Figure 2-15 for a detailed anatomy of the floppy cable. Remember, you can only have 2 floppy drives connected at any given time. The color stripe on the cable should face toward the top of your chassis, or toward the battery on the motherboard. Please refer to your documentation for proper installation.

INSTALL

Some symptoms of incorrectly installed floppies are:

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

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

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

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

• Light on the floppy is on constantly: a dead giveaway that the cable

is on backwards. 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 to assure proper operation and a quick installation, adhere to these guidelines:

• NEVER force a card into a slot. If it doesn’t fit, look at the

important!

warning

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

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

slot. You will void your warranty and damage your system board if you do this.

• When plugging the card in, especially when installing long cards,

try to push the entire card in at one time. Don’t force one end of the card into the socket first and then the other. This will create a rocking motion between the card and the slot and it will damage the pins within the socket.

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

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

• NOTE: This motherboard operates on a 3.3 volt standby for PCI

v2.2. Because of this, you need to UNPLUG the AC power cord before installing your card. Otherwise, the motherboard may automatically power up when the card is inserted into the slot.

If you follow these basic guidelines, there shouldn’t be any problems with installation. However, if you do encounter any problems, have a qualified professional install your cards for you or contact your card manufacturer. Remember, always read the manuals and installation notes that come with the adapter cards. They contain important information which will help you install the components right, the first time.

7. Connecting PS/2, USB, Serial & Parallel Devices

This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices. Note that, for this board, the PS/2 mouse port is the upper PS/2 port, and the PS/2 keyboard port is the lower PS/2 port. The PS/2 connectors are probably quite familiar to you. The USB connectors, however, may be foreign. The USB (Universal Serial Bus) is a versatile port. This one port type can function as a serial, parallel, mouse, keyboard, or joystick port. It is fast enough to support video transfer, and is capable of supporting up to 127 daisy-chained peripheral devices. Figures 2-16 and 2-17 on the following page shows the USB ports on the left and PS/2 ports on the right (respectively).

Warning: When plugging in your keyboard and mouse, or when plugging anything into a serial or Com port, make sure that the power is off. Connecting these devices and ports while the power is on is called “hot plugging,” and may damage your system.Figure 2-18 above shows the ATX double row connectors on this board. The Com and Printer ports, as well as the other ports, are labeled.

8. Connecting the Power Supply

Tyan recommends using an ATX power supply that conforms to industry standard revision 2.01. The Tiger 133 motherboard comes equipped with one onboard power connector. Figure 2-16 below shows an ATX power connector. When plugging in the power connector, make sure that the plastic clip on the power connector is aligned with the plastic tab on the onboard connector (see Figure 2-17 below). Make certain that you do not miss any pins because if you do, you will void your warranty and cause damage to yourself or your motherboard when you turn the system on. After connecting the power, make sure the connector is seated firmly into its socket so it will not become loose or fall off when the computer is jostled or moved.

Y ou are done!

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

BIOS Configuration

Introduction to Setup

The BIOS section of the manual is subjected to change without notice and is

important!

provided here for refer ence purposes only. The settings and configurations of the BIOS are current at the time of print, although they may not be exactly the same as that displayed on your screen.

This manual describes the A ward BIOS Setup program. The Setup program lets you modify basic system configuration settings. The settings are then stored in a dedicated battery-backed memory , called NVRAM, that retains the information when the power is turned off.

The A ward BIOS in your computer is a customized version of an industrystandard BIOS for IBM PC AT–compatible personal computers. It supports Intel x86 and compatible processors. The BIOS provides critical low-level support for the system central processing, memory, and I/O subsystems.

BIOS

The Award BIOS has been customized by adding important, but nonstandard, features such as virus and password protection, power management, and detailed fine-tuning of the chipset controlling the system. The rest of this manual is intended to guide you through the process of configuring your system using Setup.

S1834 Tiger 133

Chapter 3

BIOS Configuration

Starting Setup

The A ward BIOS is immediately activated when you first turn on the computer . The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the poweron self test (POST).

When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.

During POST , you can start the Setup program in one of two ways:

1. By pressing <Del> immediately after switching the system on, or

2. By pressing the <Del> key when the following message appears briefly at the bottom of the screen during POST:

TO ENTER SETUP BEFORE BOOT PRESS DEL KEY

If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the RESET button on the system case. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the correct time and the system does not boot, an error message appears and you are again asked to

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

Setup Keys

The table on the following page shows how to navigate in Setup using the keyboard.

Getting Help

Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. T o exit the Help Window press <Esc> or the F1 key again.

In Case of Problems

If, after making and saving system changes with Setup, you discover that your computer is no longer able to boot, restart by either using the ON/OFF switch, the RESET button or by pressing <Ctrl>, <Alt> and <Delete> at the same time, or clear the CMOS (see page 15 for details) The best advice is to alter only settings that you thoroughly understand. In particular, do not change settings in the Chipset screen without a good reason. The Chipset defaults have been carefully chosen by Award Software or your system manufacturer for the best performance and reliability. Even a seemingly small change to the Chipset setup may causing the system to become unstable.

Setup V ariations

Not all systems have the same Setup. While the basic look and function of the Setup program remains the same for all systems, the appearance of your Setup screens may differ from the screens shown here. Each system design and chipset combination require custom configurations. In addition, the final appearance of the Setup program depends on your system designer. Your system designer can decide that certain items should not be available for user configuration and remove them from the Setup program.

Main Setup Menu

When you enter the A wardBIOS CMOS Setup Utility , a Main Menu, similar to the one shown below, appears on the screen. The Main Menu allows you to select from several Setup functions and two exit choices. Use the arrow keys to select among the items and press enter to accept and enter the sub-menu.

BIOS

The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type auto for a hard drive, the BIOS detects its specifications during POST , every time the system boots. If you do not want to select drive type auto, other methods of selecting the drive type are available:

1. Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive types 1 through 45.

2. Select User and enter values into each drive parameter field.

3. Use the IDE HDD Auto Dectection function in Setup.

Chapter 3

BIOS Configuration

The following is a brief explanation of drive specifications:

T ype:

The BIOS contains a table of pre-defined drive types. Each defined drive type has a specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors. Drives whose specifications do not accommodate any pre-defined type are classified as type user.

Size:

Disk drive capacity (approximate). Note that this size is usually slightly greater than the size of a formatted disk given by a disk-checking program.

Cyls: Number of cylinders

Head: Number of heads

Precomp: Write precompensation cylinder

Landz: Landing zone

Sector: Number of sectors

Access Mode: Auto, Normal, large, or LBA

Auto: The BIOS automatically determines the optimal mode. Normal: Maximum number of cylinders, heads, and sectors

supported are 1024, 16, and 63. Large: For drives that do not support LBA and have more than 1024 cylinders. LBA (Logical Block Addressing): During drive accesses, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders.

Memory

You cannot change any values in the Memory fields; they are only for your information. The fields show the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory . RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes).

RAM is the computer’s working memory , where the computer stores programs and data currently being used, so they are accessible to the CPU. Modern personal computers may contain up to 64 MB, 128 MB, or more.

Base Memory: T ypically 640 KB. Also called conventional memory . The DOS operating system and conventional applications use this area. Extended Memory: Above the 1-MB boundary . Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory. Other Memory: Between 640 KB and 1 MB; often called high memory. DOS may load terminate-and-stay-resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your config.sys file that start with loadhigh load programs into high memory .

Virus W arning

When enabled, you receive a warning message if a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. You should then run an anti-virus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive. Note: Many disk diagnostic programs that access the boot sector table can trigger the virus warning message. If you plan to run such a program, we recommend that you first disable the virus warning.

CPU Internal Cache/External Cache

Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPUs from 486-type on up contain internal cache

http://www.tyan.com

Page 41

memory , and most, but not all, modern PCs have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory , for even faster access by the CPU. The External Cache field may not appear if your system does not have external cache memory .

CPU L2 Cache ECC Checking

Enables Error Checking and correction (ECC) on the L2 cache onboard the CPU.

Quick Power On Self T est

Select Enabled to reduce the amount of time required to run the power-on selftest (POST). A quick POST skips certain steps. W e recommend that you normally disable quick POST . Better to find a problem during POST than lose data during your work.

Boot Sequence

The original IBM PCs loaded the operating system from drive A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C (hard disk). However, modern computers usually load the operating system from the hard drive, and may even load it from a CD-ROM drive. The BIOS now offers a large number of boot devices and boot sequence options.

Swap Floppy Drive

This option allows you to swap the floppy drives if more than one is installed. It allows you to switch the A: and B: to make B: become A: .

BIOS

Boot Up Floppy Seek

When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks. Because very few modern PCs have 40-track floppy drives, we recommend that you set this field to Disabled to save time.

Boot Up NumLock Status

T oggle between On or Of f to control the state of the NumLock key when the system boots. When toggled On, the numeric keypad generates numbers instead of controlling cursor operations.

S1834 Tiger 133

Page 42

Chapter 3

BIOS Configuration

Gate A20 Option

Gate A20 refers to the way the system addresses memory above 1 MB (extended memory). When set to Fast, the system chipset controls Gate A20. When set to Normal, a pin in the keyboard controller controls Gate A20. Setting Gate A20 to Fast improves system speed, particularly with OS/2 and Windows.

T ypematic Rate Setting

When Disabled, the following two items (T ypematic Rate and T ypematic Delay) are irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in your system. When Enabled, you can select a typematic rate and typematic delay .

T ypematic Rate (Chars/Sec)

When the typematic rate setting is enabled, you can select a typematic rate (the rate at which character repeats when you hold down a key) of 6, 8, 10,12, 15, 20, 24 or 30 characters per second.

T ypematic Delay (Msec)

When the typematic rate setting is enabled, you can select a typematic delay (the delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.

Security Option

If you have set a password, select whether the password is required every time the System boots, or only when you enter Setup.

OS Select for DRAM > 64MB

Select OS2 only if you are running OS/2 operating system with greater than 64 MB of RAM on your system.

Video BIOS Shadow

Software that resides in a read-only memory (ROM) chip on a device is called firmware. The EliteBIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such as, for example, a SCSI adaptor. Shadowing copies firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system through the 8-bit X-bus. Shadowing improves the performance of the system BIOS and similar ROM firmware for expansion peripherals, but it also reduces the amount of high memory (640 KB to 1 MB)

http://www.tyan.com

Page 43

available for loading device drivers, etc. Enable shadowing into each section of memory separately. Many system designers hardwire shadowing of the system BIOS and eliminate a System BIOS Shadow option.

Video BIOS shadows into memory area C0000-C7FFF. The remaining areas shown on the BIOS Features Setup screen may be occupied by other expansion card firmware. If an expansion peripheral in your system contains ROMbased firmware, you need to know the address range the ROM occupies to shadow it into the correct area of RAM.

If Enabled, it reduces the turn around time for a memory read is followed by a memory write consecutively .

System BIOS Cacheable

If Enabled, results in better system performance by permitting caching of the system BIOS ROM at F0000h-FFFFFh. Any program which tries to write to this memory area, however, may cause a system error .

Video RAM Cacheable

Increases video performance by caching video memory.

AGP Aperture Size

Select the size of the Accelerated Graphics Port (AGP) aperture. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. See www .agpforum.org for AGP information.

AGP-4x Mode

Enables the 4X AGP mode for higher AGP throughput. A 4X AGP graphics card is required to enable this function. Due to T yan’s commitment to advanced technologies and first to market, not all high performance 4X AGP graphics cards are compatible w/ our S1834 at the time of print, please go to our web site for the latest update.

AGP Driving Control

Due to the compatibility of some AGP cards with the chipset this setting is used to fine tune these issues. Default is set to Auto.

AGP Driving V alue

This is the value set for the AGP Driving control. The manufacturers recommended setting is set to CC and it is suggested not to change this value.

The chipset contains an integrated USB controller. Select Enabled if you have USB peripherals.

USB Keyboard Support

This function enables the use of a USB Keyboard. Default is Disabled.

CPU to PCI Write Buffer

When this field is Enabled, writes from the CPU to the PCI bus are buffered to compensate for the speed differences between the CPU and the PCI bus. When Disabled, the writes are not buffered and the CPU must wait until the write is complete before starting another write cycle.

PCI Dynamic Bursting

When Enabled, every write transaction goes to the write buffer . Burstable transactions then burst on the PCI bus; nonburstable transactions do not.

PCI Master 0 WS Write

When this field is Enabled, writes to the PCI bus are executed with zero wait states.

BIOS

PCI Delay T ransaction

The chipset has an embedded 32-bit posted write buffer to support delay transaction cycles. Select Enabled to support compliance with PCI specification version 2.1.

PCI#2 Access #1 Retry

Select Enabled to rotate priority of PCI masters.

AGP Master 1 WS Write / Read

Select Enabled to add one clock tick to AGP write operations.

Flash Writer Utility

You can upgrade the BIOS on your motherboard by using the Flash Memory Writer (FMW) utility . This utility can be downloaded from TYAN’s BBS and from the TY AN website.

The following three files make up the FMW: A WDFLASH.EXE The Flash Memory Writer utility for A ward to

BIOS Configuration

BIOS will be solved by this simple procedure (see Hardware CMOS & Password Reset, page 16).

T o reprogram the system BIOS, the CPU must be running in real mode. FMW will not run if the CPU is operating in a protected or virtual mode. This means that you cannot run it with Windows running or with any memory manager software. You must disable any memory manager software before you can run FMW. The easiest way to do this is as follows:

1) Boot your system from a bootable floppy disk with no CONFIG.SYS or AUTOEXEC.BAT files, and then run FMW from a backup copy of your support disk. You can make your back-up floppy bootable when you format it, and use one disk for both purposes.

2) If you are using MS-DOS 6.x, you can use the feature that allows you to bypass the CONFIG.SYS and AUTOEXEC.BAT files. You can access this feature by pressing <F5> while the “Starting MS-DOS...” line is on the screen during boot-up.

If you are uncertain whether or not you have a memory manager running, try FMW. If it works, then there is no active memory manager on your system. If you see a warning message about the CPU mode, follow the above directions to get around the memory manager.

Once you have your CPU in real mode, you can run FMW. Y ou can copy the contents of the “Flash” directory to your hard drive, or you can run the utility from a backup of the support floppy disk. Either way, make sure that the new BIOS file is in the same directory as the FMW utility. T o start FMW, change to the “Flash” directory if you are not already in it. T ype “awdflash” at the DOS command line and press the <Enter> key. The FMW utility screen will appear:

Y ou should choose “Yes” to save the original system BIOS to a floppy diskette before you program the new BIOS. This leaves you with a backup of your original BIOS in case you need to re-install it. If you cannot successfully program the new BIOS file for some reason, re-install your original BIOS from the backup file. Remember, always reset the CMOS after flashing to a new BIOS (see page 15).

Glossary

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

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

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

ATAPI (AT Attachment Packet Interface), also known as IDE or A TA, is a drive

implementation that includes the disk controller on the device itself. It allows CD-ROMs and tape drives to be configured as master or slave devices, just like hard drives.

ATX form factor was designed to replace the A T form factor . It improves on the AT design by rotating the board ninety degrees, so that the IDE connectors are closer to the drive bays, and the CPU is closer to the power supply and cooling fan. The keyboard, mouse, serial, USB, and parallel ports are built in.

GLOSSARY

Bandwidth refers to carrying capacity. The greater the bandwidth, the more

S1834 Tiger 133

Page 64

Appendix

Glossary

data the bus, phone line, or other electrical path, can carry. Greater bandwidth, then, also results in greater speed.

The BIOS (Basic Input/Output System) program resides in the ROM chip, and provides the basic instructions for controlling your computer’s hardware. Both the operating system and application software use BIOS routines to ensure compatibility .

A buffer is a portion of RAM which is used to temporarily store data, usually from an application, though it is also used when printing, and in most keyboard drivers. The CPU can manipulate data in a buffer before copying it, all at once, to a disk drive. While this improves system performance--reading to or writing from a disk drive a single time is much faster than doing so repeatedly-there is the possibility of losing your data should the system crash. Information stored in a buffer is temporarily stored, not permanently saved.

A bus is a data pathway. The term is used especially to refer to the connection between the processor and system memory, and between the processor and PCI or ISA local buses.

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

A cache is a temporary storage area for data that will be needed often by an application. Using a cache lowers data access times, since the needed information is stored in the SRAM instead of in the slower DRAM. Note that the cache is also much smaller than your regular memory: a typical cache size is 512KB, while you may have as much as 1GB of regular memory.

Cache size refers to the physical size of the cache onboard. This should not be confused with the cacheable area, which is the total amount of memory which can be scanned by the system in search of data to put into the cache. A typical setup would be a cache size of 512KB, and a cacheable area of 512MB. In this case, up to 512MB of the main memory onboard is capable of being cached. However, only 512KB of this memory will be in the cache at any given moment. Any main memory above 512MB could never be cached. Closed and open jumpers Jumpers and jumper pins are active when they are On or Closed, and inactive when they are Off or Open.

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

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

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

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

DMA Direct Memory Access channels are similar to IRQs. DMA channels allow hardware devices (like sound cards or keyboards) to access the main memory without involving the CPU. This frees up CPU resources for other tasks. As with IRQs, it is vital that you do not double up devices on a single line. Plug and Play devices will take care of this for you.

In Doze mode, only the CPU’ s speed is slowed.

DRAM Dynamic RAM is a widely available, very affordable form of RAM which has the unfortunate tendency to lose data if it is not recharged regularly (every few milliseconds). This refresh requirement makes DRAM three to ten times slower than non-recharged RAM such as SRAM.

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

EEPROM Electrically Erasable Programmable ROM, also called Flash BIOS, is a ROM chip which can, unlike normal ROM, be updated. This allows you to keep up with changes in the BIOS programs without having to buy a new chip. TYAN’s BIOS updates can be found on the website.

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

Firmware is low level software that controls the system hardware.

Form factor is an industry term for the size, shape, power supply type, and external connector type of the PCB (personal computer board) or motherboard. The standard form factors are the AT and ATX, although TYAN also makes some Baby-AT boards.

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

Handshaking is a form of encryption. One system, typically the server , sends an encryption scheme to another agent, typically a client. Thus, the client’s data is protected during transmittal to the server.

HDD stands for Hard Disk Drive.

H-SYNC controls the horizontal properties of the monitor.

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

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

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

IDE INT (IDE Interrupt) is a hardware interrupt signal that goes to the IDE. I/O Input/Output is the connection between your computer and another piece

of hardware (mouse, keyboard, etc.).

IRQ An Interrupt Request is an electronic request that runs from a hardware device to the CPU. The interrupt controller assigns priorities to incoming requests and delivers them to the CPU. It is important that there is only one device hooked up to each IRQ line; doubling up devices on IRQ lines can lock up your system. Happily, Plug and Play operating systems take care of these details for you.

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

Latency is the amount of time that one part of a system spends waiting for another part to catch up. This is most common when the system sends data out to a peripheral device, and is waiting for the peripheral to send some data back (peripherals tend to be slower than onboard system components). NVRAM ROM and EEPROM are both examples of Non-Volatile RAM, memory that holds its data without power. DRAM, in contrast, is volatile.

OEMs (Original Equipment Manufacturers) like Compaq or IBM package other companies’ motherboards and hardware inside their case and sell them.

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

PCI stands for Peripheral Component Interconnect. PCI is a 32-bit local bus (data pathway) which is faster than the ISA bus. Local buses are those which operate within a single system (as opposed to a network bus, which connects multiple systems).

The PCI PIO (PCI Programmable Input/Output) modes are the data transfer modes used by IDE drives. These modes use the CPU for data transfer (DMA channels do not). PCI refers to the type of bus used by these modes to communicate with the CPU.

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

Pipeline burst SRAM is a fast secondary cache. It is used as a secondary cache because SRAM is slower than SDRAM, but usually larger . Data is cached first to the faster primary cache, and then, when the primary cache is full, to the slower secondary cache.

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

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

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

Glossary

The term RAM (Random Access Memory), while technically referring to a type of memory where any byte can be accessed without touching the adjacent data, is often used to refer to the system’s main memory. This memory is available to any program running on the computer.

ROM (Read-Only Memory) is a storage chip which contains the BIOS (Basic Input/Output System), the basic instructions required to boot the computer and start up the operating system.

SDRAM (Synchronous Dynamic RAM) is so-called because it can keep two sets of memory addresses open simultaneously. By transferring data alternately from one set of addresses, and then the other, SDRAM cuts down on the delays associated with non-synchronous RAM, which must close one address bank before opening the next.

The serial port is so called because it transmits the eight bits of a byte of data along one wire, and receives data on another single wire (that is, the data is transmitted in serial form, one bit after another).

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

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

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

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

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

UltraDMA/66 is a fast version of the old DMA channel. UltraDMA is also called UltraATA. Without UltraDMA your system cannot take advantage of the higher data transmission rates of the new UltraATA hard drives. Universal Serial Bus or USB, is a versatile port. This one port type can function as a serial, parallel, mouse, keyboard, or joystick port. It is fast enough to support video transfer, and is capable of supporting up to 127

daisy-chained peripheral devices.

VGA (Video Graphics Array) is the PC video display standard.

V-SYNC controls the vertical properties of the monitor.

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

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