1.4 Technical Support

If a problem arises with your system, you should turn to your dealer for help first. Your system has most
likely been config ured by them , and they sh ould have the be st idea of what hardw are and so ftware your
system contains. Hence, they sh ou ld be of the mo st assist ance. Furthermore, if you p urch ase d you r sys­tem from a dealer n ear you, you can a ctually bring your syste m to them to have it serviced, instead of
attempting to do so yourself (which can have expensive consequences).

Help Resources:

1. See the FAQ and beep codes section of this manual.

2. See the Tyan website for FAQ, bulletins, driver updates, and other
information: http://www.tyan.com

3. Contact your dealer for help BEFORE calling Tyan.

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

1.5 Returning Merchandise for Service

http://www.tyan.com

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, an d place it on a ground ed antistatic surface, component side up.
Inspect the board for damage.

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

Press down on any of the socke ted ICs if it appe ars that t hey are not prope rly seated (the board shou ld
still be on an antistatic mat). Do n ot touch th e bottom of the board. Remember, don’t take any electronic
device out o f i ts p ro t ec ti v e bag un t i l y o u a r e r e ad y t o a c t ua ll y i n s tal l it i nto t he c o mp ute r ca s e . If yo u do n ot
ground yourself, yo u ri sk zapping the mo therb oard o r adap ter card . Subseq uent pr oble ms may not ari se
immediately because electrostatic discharge, unlike physical damage, causes the device to fail over time.

2.4 Quick References for Jumpers

In this manual, the term “closed” and “on” are used when referring to jump ers (or jumper pins) th at are
active; “open” a nd “off” a re u sed whe n re fer ri ng to ju mp ers (or jumper pin s) th at are inactive. See Figure

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

Jumpers and pins are con nected by slipping the plasti c jumper connector over the top of two adjacent
jumper pins ( indicated by 1- 2 or 2-3). The met al rod inside t he plastic sh ell b ridges the ga p betw een the
two pins, completin g the circuit. 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 p ages will help you set the jum pers for CPU speed, infr ared, 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.

2.7 Mounting the Motherboard into the Chassis

Your chassis may include moun ting hardwar e. If mounting hardware was included, yo u can use the fo l­lowing examples to help you in installing your motherboard into the chassis.

The chassis may h ave com e with th e studs integrated in to t he cha ssis wa ll, so in t hose ca ses you wou ld
only need to us e scre ws (possib ly inclu ded wi th you r chass is) to i nstall th e mot herboa rd. S ee the exam­ples (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 usin g the mounting hardware as sho wn in the examples below. Remember not to over­tighten any of th e screws, or you migh t risk breaki ng intern al traces i n the surroun ding ar ea, or dam age
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 i nd t hat a lthough some mem or y m od ul es m ay ap pe ar to b e hi gh -q uali ty, they may con­tain inferior or substandard p arts. The type o f memory you ch oose to instal l should be checke d against
the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com

Memory Installation Procedure

Here are some details of memory installation for this board:

At least one unbuffered DIMM must be installed for the system to POST.

The motherboard supports 64MB, 128MB, 256MB, and 512MB PC100/133 SDRAM.

All installed memory will be automatically detected, so there is no need to set any jumpers.

The motherboard supports up to 1.5 (3 DIMMs)* or 2 GB (4 DIMMs)* of memory.

Insert the DIMM by pushing the modul e into the socket wit h even force. Do not insert one

Step

1

end and then the ot her: instal l the whole module at onc e or you m ight bend the DIMM pin s.
Make sure the DIMM is securely seated.

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

Removing a DIMM

Removing a DIMM is just the reverse : si mply pu l l back the clips fro m the D IM M (see pictur es belo w), and
carefully pull the module straight out. Place the DIMMs in an anti-static bag as soon as you remove them
to avoid static damage.

2.9 Installing the CPU and Cooling Fan

Intel Pentium III FC-PGA processors (500 MHz through 1 GHz) or a single FC-PGA type Celeron proces­sor 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 Intel Pentium III FC-PGA CPU

Before installing the CPU, check it for any visible damage. Make su re none of the pins are 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

Step

Step

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

1

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

2

two angled corners on the socket. Carefully install the CPU by lining
both Pin 1 on th e CPU and Pin 1 on the s ocket, making 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

Installing the Cooling Fan

After the CPU has been installed, you will need to install t he proper cooling device fo r the CPU. This
device, a heatsink /fan combina tion, can be p urchased a t many comp uter retail st ores. In stallation o f the
cooling device may vary d epending on the fan manufactur er’s design. You should also take spa ce into
consideration when in stal l a cooling device: 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 that you use some type of
thermal compound (available from computer retail
stores), between the CPU 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 CP U socket, and/or the
CPU itself. See Figure 2.2 (see right) for an example of
how to connect the cooling fan’s power supp ly. Another
diagram has als o be en pro v ide d be l ow, to aid in CP U fan
installation onto the socket.

2.10 Connecting IDE and Floppy Drives

A variety of IDE and ATAPI-compliant devices* can be
installed on this motherboard, such as hard disk drives
(HDDs) and CD-ROMs.

Please keep in mind that on this motherboard, the primary IDE
connector is BLACK, and the secondary IDE connector is
WHITE. See Figure 2.3 (right) for an example of the IDE cable
properly connected to the motherboard. Consult the documen­tation that came with your IDE/ATAPI device, or contact the
device’s manufacturer for more details on installation.

Also see Figure 2.4 (right) for an example of the HDD with the
IDE cable installed. Please note that Ultra DMA-66 IDE HDDs
require a special 80-wire cable which has additional grounding
wires. This cab le has been inclu ded with thi s moth erboa rd for
your convenience. The UltraDMA-66 cable is upwards com­patible with UltraDMA-100 IDE HDDs, and backwards com­patible with UltraDMA-33 and legacy IDE HDDs.

The BLUE end of the AT A-66 cable must connect to the motherboard. The black con­nector on the ATA-66 cable is for the master HDD, and the g rey connec tor is for the
slave HDD. See Figure 2.3 (above) for an example o f installation on the mother-

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
six 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 touc hing .

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 2.6a) and after (Figure 2.6b) example insta l la t ion i ma g es
below for details.

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 2.7 below).

The PS/2 connectors are probably quite familiar to you, while the USB connectors may not be. A USB
port can function as a serial, parallel, mouse, keyboard, display, or joystick port. It is capable of supporting
up to 127 daisy-chained peripheral devices. All external ports are labeled in Figure 2.7, shown below.

2.13 Connecting the power supply

This motherboard requires an ATX power supply. Tyan recommends using one that conforms to industry
standard Revision 2.01. The images below show the A TX power connector before (Figure 2.8a) and after
(Figure 2.8 b ) it has been plugged in. The clip on the power connector should lock over the tab on the
onboard connector. You shouldn’t be able to plug the power connector in any other way but just to be
safe, make sure it looks like Figure 2.8b. 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.

You 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 seem 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 p. 7).

2.14 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 will help the situation as well. Many memory modules are not suit­able for high performance systems and are probably the main source of your problem. Also check to
make sure you are using an ATX 2.01 compliant or better power supply. 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 o r your distributor for ass istance 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.37) 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” error 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, don’t forget to check the Clear CMOS section (see p.12) so that you can reset your CMOS.

Chapter 3: BIOS Setup

Introduction to the BIOS setup

The BIOS is the basic input/output system, required by the computer to perform functions such as CPU
and hard drive support. This chapter describes different settings for Award BIOS that can be used to con­figure your system.

The BIOS section of the manual is subject to change without notice and is provided here for refer­ence purposes only. The settings and configurations of the BIOS are current at the time of print,
and therefore they may not be exactly the same as that displayed on your screen.

The manual describes the Award BIOS setup program. The setup program lets you modify basic 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 Award BIOS in your computer is a customized version of an industry-standard 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.

The BIOS has been customized by adding important, but non-standard, features such as virus and
password protection, power mangement, 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 usi ng the Award BIOS setup program.

Starting Setup

The 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 Power-On Self Test (POST).

When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage
devices (HDD, FDD, etc.) and if one is found, the BIOS will launch that operating system and hand control
of system operations to it. During POST, you can start the setup program by pressing the [DEL] key when
the “Press DEL key to enter BIOS setup” message appears on the screen.

In Case of Problems

If you discover that you have trouble boot ing the computer after making and saving change s with the
BIOS setup program, you can restart the computer by either:

Pressing [CTRL]+[ALT]+[DEL] (all three keys at the same time), or

Holding the power button down until the computer shuts off, then reset the CMOS (see p. 15)

Tiger 230 S2507

The best advice is to alter on ly sett ings that yo u thoro ughly un dersta nd. In pa rticu lar, do not change set­tings in the Chips et screen unless you are abso lutely sure that you need to. T he Chipset defa ults were
carefully chosen f or the b est perfo rmance a nd reliab ility. Even a seemingly small chan ge to th e Chipse t
setup may cause the system to become unstable.

Setup Variations

Not all systems have the same setup program. W hile the basic look and fu nction of the setup prog ram
remains more or less the same for all system, the appearance of your Setup screen may differ from other
Award BIOS screens. Each system des ign and chipset combination req uire custom configurations. In
addition, the final appearance of the setup program depends on your system designer. You system
designer can decide that certai n items should no t be available for user config uration, and r emove them
from the BIOS setup program.

General Help

At any time, you can p res s [F1] to bring up a G en era l H elp scre en in ca se you want to learn the sho rtcu t

Chapter 4: System Resources

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

following order:

CPU, MEMORY, VIDEO

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 webs ite 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 Award 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 Displayed Error Messages

If an error occurs after the system display has been initialized, an error message will be displayed as fol­lows:

Appendix I: Glossary

ACPI (Advanced Configura tion and Power Interface): a power m anage ment s pecif ication 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 (A
3D graphics applicati ons. Th e 32-bit AG P channel di rectly l inks the grap hics contro ller to the mai n 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.

AMR (A
Intel’s core logic chipsets supporting AC-link 2.1. It supports fax and all data feedback modes. It provides
high speed communications between your personal computer and a remove lcoation, such as an Internet
Service Provider (ISP).

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

ATAPI (AT

the disk controller o n the dev ice itself . It allow s CD-ROM s and tap e driv es to be confi gure d as master or
slave devices, just like HDDs.

ATX: the form factor desig ned to rep lace the AT form factor. It improves on the AT design by rotating the
board 90 degrees, so that the IDE connectors ar e closer to the d rive bays, and th e CPU is closer to the
power supply and cooling fan. The keyboard, mouse, USB, serial, and parallel ports are built-in.

ccelerated Graphics Port): a PCI- base d inte rfa ce w hich was de si gn ed spe cifi cally for dem and s of

Bandwidth: refers to car rying cap acity. The greater the ban dwidth, the more data the bus, phone line, or
other electrical path, can carry. Greater bandwidth, then, also results in greater speed.

BBS (B
center for users to post messages and access information.

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 i s u sed to te mp ora ri ly sto re d ata , usu al ly fr om an a ppli ca ti on , tho ugh it i s
also used when printing , and in most keyboa rd drivers . The CPU can manip ulate dat a in a buffer before
copying it, all at once, to a disk drive. While this im proves system performance -- - reading to or writing
from a disk drive a single time is much faster th an doing so repeatedly - -- there is also t he possibility of

GLOSSARY

Bus: a data pathwa y. The term is used especi ally to refer to the con nection 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).

Cache: a temporary storage area for data that will be needed often by an application. Using a cache low­ers data access times, sin c e th e ne ed ed in for mat ion i s st ore d in t he S RA M in stea d o f in the sl ow DR AM .
Note that the cache is al so mu ch sm alle r th an your regular mem or y: a typi ca l cach e size i s 51 2KB , wh ile

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”.

and falling edge of the system clock rather than on just the rising edge, potentially doubling output.

DIMM (D
need to be installed in pairs.

DIMM bank: 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 capa ble of acting as a memor y
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.

makes DRAM three to ten times slower than non-recharged RAM such as SRAM.

EDO RAM (E
addresses are static; the next time it looks for a bit of data, it will be at the same spot, or one nearby.

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

Tiger 230 S2507

43

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

board, etc.)

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 to ea ch IRQ line; doub ling up de vices on IR Q lines ca n lock up yo ur system .
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 dev ice, a nd it waiting for the perip 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
bus. Local buses are t hose which operate within a s ingle system (as oppose d to a network bus, which
connects multiple systems).

PCI PIO (PCI P
modes use t he CPU for data transfer (in contras t, DMA chan nels do no t). PCI ref ers to the t ype 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 usual ly larger. Data is cached first to the faster primary ca che, and th en, when the pri­mary cache is full, to the slower secondary cache.

PM timers (P owe r M ana gem en t ti me rs) : soft ware ti me rs th at co unt down the number of secon ds or min­utes until the system times out and enters sleep, suspend, or doze mode.

PnP (P

lug-n-Play): a design sta ndard that has beco me ascendant in th e industry. Plug-n-Play devices
require little set- up to use. Novice en d users can simply plug them into a computer that is running on a
Plug-n-Play aware o perating syst em (such as Windows 9 8), and go to work. De vices and o peratin g sys­tems that are not Plug-n- Play require you to recon figure your system each tim e you add or change an y
part of your hardware.

Striping: see RAID.

RAID (R

on many hard drives . By using this method , the data i s stored red undantly, also the multiple ha rd drive s
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 hard drives, but offers no faul t-tolerance. RAID level 1 is known as
mirroring, which sto res the data within at least two har d drives, but does not stripe. RA ID level 1 also
allows for faster acce ss time and fault-tole rance, since either hard drive can be read at the same time.
RAID level 0+1 is both striping and mirroring, pro viding fault-t olerance, stripi ng, and faster acce ss all at
the same time.

RAM (R
without touching the adjacent da ta, is often used to refer to the syste m’s main memory. This memory is
available to any program running on the computer.

ROM (R
boot the computer and start up the operating system.

SDRAM (S
addresses open simulta neously. By transferring data alter nately fro m one set of addresse s and then the
other, SDRAM cuts down on the delays associate d with non-synchronous RAM, which must close one
address bank before opening the next.

edundant Arra y of Ind ependent Disks): a wa y for the sa me data to be stored in differe nt places

ead-Only Memory): a storage ch ip which contains the BIOS; the basic instructio ns required to

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

GLOSSARY

Serial port: called as such because it t ransmits 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 (S
must be installed in pairs, and do not have the carrying capacity or the speed of DIMMs.

SIMM bank/s ocket : SIMM socke ts are the physical s lots into which you install SIMM mod ules. A pair of
SIMM sockets form a SIMM bank, and act as one unit. If only one socket is filled, th e bank will not oper­ate.

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

SRAM (Static RAM): unlike DRAM , this type of RAM does not need t o be refreshed in order to pre vent

data loss. Thus, it is faster, and more expensive.
Standby mode: in this mode, the video and fixe d disk drive (usually the HDD) shuts down; a ll other
devices continue to operate normally.

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.
