INTRODUCTION
OVERVIEW

The Western Digital WD1009V Controller is a high performance, ESDI (Enhanced Small Device
Interface) hard disk controller. The WD1009V is compatible with Industry Standard Architecture (ISA)
and Enhanced Industry Standard Architecture (EISA) PC/AT machines. While either of the WD1009V
controllers can be installed in an EISA system, only the enhanced EISA controller provides the EISA
Autoconfiguration capability. Refer to Identify Your Controller Type to determine if your controller is
an SE1 or SE2, and if the controller has the EISA Autoconfiguration capability. There are two
WD1009V models. Each WD1009V-SE1 interfaces up to two ESDI-compatible hard disk drives to the
PC/AT system. Each WD1009V-SE2 interfaces up to two ESDI-compatible hard disk drives and a
maximum of three floppy drives (5 1/4 and/or 3 1/2 inch) to the PC/AT system.

Features include:

þ High speed ESDI drive interface (10-24Mbit/sec)

þ Utilizes the maximum storage capacity of ESDI drives by using a highly

efficient Translation Mode
þ 1:1 interleave

þ 64KBytes of multi-segmented adaptive look ahead cache, which reduces disk access time and
increases data throughput One alternate sector per track for bad sector sparing

þ WD1009V-SE2 provides two floppy drive standard support, or three floppy drive support with the
use of software drivers

þ Automatic defect management

þ Block mode transfer capability

þ 100% compatible with IBM PC/AT Can support up to four ESDI drives with the use of two
WD1009V controllers and proper software drivers

þ Automatic head and cylinder skewing

The EISA enhanced version of the WD1009V Controller supports EISA auto-configuration and type B
DMA data transfers. The instructions in this manual describe the non-EISA enhanced configuration and
installation. Refer to Appendix A for EISA-specific information.

BIOS ROM

The use of WD1009V BIOS ROM is optional, however we recommend you use it to achieve maximum
flexibility, performance, and adaptability with different drives. The WD1009V BIOS ROM reads the
ESDI information and generates the appropriate drive table for your drive.

Many system BIOS (Basic Input Output System) ROMs support older MFM/ST506 drives that only
support 17 sectors per track. The ESDI disk drive typically has 34 or more sectors per track.
Therefore, your system BIOS ROM may not adequately support your ESDI drive.

If your system BIOS does not support the necessary drive tables, you must use the WD1009V BIOS.
The WD1009V default configuration enables the WD1009V BIOS. Refer to Configuring The 1009V
Controller for more information on the WD1009V BIOS ROM.

If you are installing a hard drive in your system and you want to use the system BIOS to configure your
drive, you need to determine if your system BIOS provides the appropriate drive tables for the
installation of your ESDI drive into your AT system. The drive tables specify the number of
cylinders, heads, and sectors per track (SPT). When installing an ESDI drive in an AT system, you
must match the number of cylinders, number of heads, and sectors per track exactly.

If you decide to use your system BIOS, you need to use a third party formatting software package, or
Western Digital's formatting program WDFMT, which is available on Western Digital's Technical
Support Bulletin Board. WDFMT does not support automatic defect mapping. To access the
WDFMT program, contact the bulletin board via your Hayes-compatible modem. We strongly
recommend you use the WD1009V BIOS, which does not require WDFMT or third party software.

PRECAUTIONS

Western Digital products are designed to withstand normal handling when unpacking and installing the
controller. Be aware of the following precautions when unpacking and installing the WD1009V
Controller. Be careful when handling the controller. Do not drop or cause shock to the components.
Doing so can permanently damage the controller and void the warranty.þHandle the WD1009V
Controller by the edges to avoid touching the components. Chips are static-sensitive and can be
damaged if not handled correctly.

There are two WD1009V Controller models: the SE1 and SE2. The SE1 is a hard drive-only controller.
The floppy controller is either on the motherboard, or you have a separate floppy controller. Figure 1
illustrates the WD1009V-SE1 Controller.

Figure 1: WD1009V-SE1 Controller, Non-EISA Enhanced Version

The SE2 is a hard drive and floppy drive controller. You must remove or disable any other floppy
controller in your system before installing the WD1009V-SE2. Figure 2 illustrates the WD1009V-SE2
Controller. The visible differences between the models are the absence of the J1
connector, and jumpers W2, W3, and W6 are depopulated (no jumper pins exist) on the SE1 model.
This is because J1 is the floppy connector on the SE2 model, and jumpers W2, W3, and W6 control
floppy-related configuration settings.

You also need to determine if your controller is the enhanced EISA version of the WD1009V. The
EISA enhanced controller has a chip installed in location U51 and is capable of EISA Autoconfiguration.
Remember, either of the WD1009V controllers can be installed in an EISA or ISA system.
However, only the enhanced EISA controller provides the EISA Autoconfiguration capability. Refer to
Figures 1 and 2 to locate the U51 chip location.It is important to identify your model and controller type
prior to configuration and installation.

Figure 2: WD1009V-SE2 Controller, Non-EISA Enhanced Version

IDENTIFY YOUR CABLES

The configuration procedures you will follow in this manual depend on the type of cables you are using
with the WD1009V Controller. Therefore, it is important to identify the type of cables you have.
There are two basic types of control cables: twisted or straight. A twisted hard drive control cable
twists or swaps five cable lines from pins 25 to 29. The floppy drive cable twists seven lines (10 to 16).
The twist on the floppy cable is closer to pin 1.

When installing three floppy drives, there are two types of twisted floppy cables: the end-twisted cable
and the center-twisted cable. Again, seven lines (10 to 16) are twisted and are close to pin 1. Pin 1 is
usually identified by a color stripe on the cable, and/or a notch on the connector.

Be careful not to confuse the hard drive control cable with the floppy cable. They are not
interchangeable. Both cables have 34-pin connectors.It is important to remember that the floppy cable is
usually twisted, and the twist is closer to pin 1. If your hard drive cable is twisted, the twisted portion
consists of exactly five wires.
During cable connection, it is also important to remember that the twisted end of the cable is the end
connector. The end connector is installed on the drive connector, not the controller connector. Data
cables are hard drive cables that have two 20-pin connectors. Each data cable is connected from the
hard drive to the controller.

INSTALLATION STEPS

The following steps provide an overview of the procedures required to configure, install, and use the
WD1009V Controller in your system:

1. Configuring the WD1009V.

2. Configuring your disk drives.

3. Installing the WD1009V.

4. Preparing the WD1009V for use.

5. Partitioning.

6. Performing a high-level format.

The instructions in this manual describe a non-EISA enhanced configuration, installation, and
preparation. Refer to Appendix A for information on the EISA Autoconfiguration capability.


CONFIGURING THE WD1009V CONTROLLER


OVERVIEW


It is rarely necessary to change the WD1009V configuration. This section describes the controller's key
configuration options, jumper descriptions, and default and optional jumper configuration. If you need
to change the default configuration, you most likely need to install a jumper shunt on
designated jumper pins. A jumper shunt is a small plastic bracket that fits over two jumper pins at a
time. Jumper shunts may be purchased at a computer supply store.

KEY CONFIGURATION OPTIONS

The WD1009V Controller provides a number of configuration options:

þ Physical or Translation Mode selection

þ 1009V BIOS enable

þ Alternate sectors

þ Cacheing

þ EISA autoconfiguration

Physical and Translation Mode Selection

Your hard disk drives communicate with the controller in physical terms, which consist of the actual
physical parameters of the drive. The WD1009V Controller has two possible modes for data storage
and retrieval: Physical and Translation. The Physical Mode supports the actual physical parameters of
the drive (cylinders, heads, and sectors per track). The Translation Mode describes the drive to the host
system in logical parameters. Some hosts only recognize 17 sectors per track. In this instance, you
need to use Translation Mode to access all sectors. Some drives are larger than the DOS limitation of
528MB. The WD1009V Translation Mode provides a translation table that fully utilizes the capacity of
the ESDI drive. Most personal computers address disk space through the INT 13 software interface.
Most INT 13 interfaces have cylinder, head, and sector address limitations. The WD1009V BIOS
provides translation tables to maximize the disk space addressed by INT 13. It maps the physical
characteristics of the drive into logical parameters. The Translation Mode converts the operating system
logical parameters to actual physical drive parameters so that all physical sectors on the disk may be
used.

In the WD1009V default configuration Translation Mode is enabled. When Translation Mode is
disabled, all disk mapping is based on the drive's physical parameters. Refer to Figure 4 for WD1009V
jumper locations, and Table 1 for more information on default and optional configuration settings.


---------------------------------------------------------------------------
1009V BIOS ENABLE
---------------------------------------------------------------------------

In the WD1009V default jumper configuration, the WD1009V BIOS is enabled. We strongly recommend
you use the WD1009V BIOS. If you want to disable the WD1009V BIOS, you need to determine if
your system BIOS provides the appropriate drive tables for your ESDI drive. If your system BIOS does
not support the necessary drive tables for your drive, you must use the WD1009V BIOS.

Drive tables specify to the host the number of cylinders, heads, and sectors per track. When integrating
an ESDI drive into your system, the number of heads and sectors per track must match exactly.

As discussed in the Introduction, using the WD1009V BIOS achieves maximum flexibility and
adaptability with different drives. The WD1009V BIOS reads the ESDI drive information and
automatically generates the appropriate drive tables.

Note: Formatting with alternate sectors enabled reduces the available storage on your drive.
---------------------------------------------------------------------------
ALTERNATE SECTORS
--------------------------------------------------------------------------
In the WD1009V default jumper configuration, the alternate sector feature is disabled. Enabling
alternate sectors reserves one sector per track for defect management.

The alternate sector feature provides the ability to map out defects so that a near error-free drive can be
presented to the operating system. Certain operating systems (such as Banyan Vines(TM) and Novell
Netware(TM)), can only handle a specific number of hard drive media defects. Refer to your operating
system documentation for more information.
CACHEING

In the WD1009V default jumper configuration, cacheing is enabled.Cacheing increases your overall
drive performance by reading ahead and buffering data sectors that are likely to be requested by the host
on subsequent read commands. The WD1009V provides 64KBytes of multi-segmented adaptive look
ahead cache. You should leave this feature enabled.

The only instance in which you may want to disable cacheing is if your application software does not
work properly with cacheing enabled. Refer to your software documentation for more information.

EISA AUTOCONFIGURATION

In the WD1009V default configuration on the EISA Autoconfiguration enhanced version of the
WD1009V, the EISA Autoconfiguration option is enabled. EISA Autoconfiguration overrides some
physical jumper settings.

For more EISA-specific information, refer to Appendix A.

JUMPER LOCATIONS

Figure 4 displays the location of jumpers W2 - W7 on the WD1009V-SE2 Controller. Remember the
SE1 controller does not have a J1 floppy connector, nor do the following jumper locations have pins:
W2, W3, and W6.

Caution: Remember to handle the controller by the edges to avoid contact with the components.

This figure displays an ISA controller. If you have an EISA Autoconfiguration enhanced controller,
there is a chip installed at location U51.

JUMPER DESCRIPTIONS

This section lists and describes all jumper settings for the WD1009V.

---------------------------------------------------------------------------
CHANGING THE CONFIGURATION
---------------------------------------------------------------------------

To change the jumper configuration:

1. Refer to Table 1 to determine your configuration.

2. To install a jumper shunt, place the shunt over the pins specified in
Table 1.

3. Push the shunt into place until it is flush against the base of the
jumper block.

---------------------------------------------------------------------------
W2 JUMPER - FLOPPY CABLE TYPE FOR THREE FLOPPY DRIVES
---------------------------------------------------------------------------

The W2 jumper specifies the type of floppy cable you are using in your installation if you are installing
a third floppy drive. If you have the WD1009V-SE1 hard drive-only controller, there are no jumper
pins to configure at this location. If you are installing one or two floppy drives, do not change the
default setting.

The default setting is a jumper installed on pins 2-3, which enables an end-twisted floppy cable for three
drives. Remove the jumper shunt from pins 2-3 and install it on pins 1-2 if you are using a
center-twisted floppy cable for three floppy drives. If you are unsure of the type of
cable you are using, refer to the Introduction to determine your cable type.

W3 JUMPER - FLOPPY DRIVE TYPE

This jumper applies to the WD1009V-SE2 Controller. This option allows you to configure the
controller for AT- or PS/2-type, 3 1/2", 1.44MByte floppy drives. The default jumper setting is a
jumper shunt installed on pins 1-2 to select an AT-type floppy drive (3 1/2" 1.44MByte). Remove the
jumper shunt from pins 1-2 and install it on pins 2-3 to designate a PS/2-type floppy drive (3 1/2"
1.44MByte).


---------------------------------------------------------------------------
W4 JUMPER - EISA CONTROLLER ENABLE OPTION
---------------------------------------------------------------------------
This jumper determines how you want the controller enabled in an EISA system. The default setting for
W4 is no jumper shunt installed. This enables the WD1009V Controller at all times. Install a jumper
shunt on pins 1-2 to allow the EISA host to enable or disable the WD1009V Controller. Leave this
jumper off if you are working in an ISA system.
---------------------------------------------------------------------------
W5 JUMPER - ESDI DRIVE AND BIOS OPTIONS
---------------------------------------------------------------------------
The W5 jumper block allows you to configure a number of important options, some of which are
dependent on your hard disk configuration or operating system capabilities. The default setting for all
W5 jumpers is no jumper shunt installed. You may need to refer to your hard disk drive or
operating system documentation in order to correctly set the controller card.

ALTERNATE SECTOR PINS 1-2 allow you to enable or disable the alternate sector capability. Install
a jumper shunt over these pins to enable the alternate sector, which reserves one sector per track for bad
sector swapping.

TRANSLATION MODE PINS 3-4 open enables Translation Mode on the WD1009V Controller. Install
a jumper shunt on these pins to disable the Translation Mode. Be sure to check your system capabilities
in matching your drive tables before you disable this feature.

SECTORS PER TRACK PINS 5-6 default setting forces your 10 or 15Mb/s drive to 35 or 53 sectors
per track (SPT) mode. Installing a jumper on pins 5-6 activates the Physical Mode. Physical Mode
parameters are determined by the drive jumper settings.

ERROR CORRECTION CODE PINS 7-8 specify the byte size of the error correction code (ECC). The
controller default setting enables a 4-byte ECC. Installing a jumper shunt on pins 7-8 enables the 7-byte
ECC, which is only used if you are performing certain diagnostics.

CACHEING PINS 9-10 allow you to enable or disable cacheing. The default setting (no jumper shunt
installed), enables the 64KBytes of multi-segmented adaptive look ahead cacheing. Cacheing increases
overall system performance by reading ahead and buffering the data sectors likely to be used by the host
on subsequent read commands. Install a jumper shunt on pins 9-10 if you want to disable cacheing. In
most cases, it is best to leave cacheing enabled. Refer to your software documentation for information
on how cacheing affects your software performance.

BIOS ADDRESS PINS 11-12 select the primary or secondary BIOS address. Leave the pins open to
select the primary BIOS address (C800:0). If a BIOS address conflict exists, install a jumper shunt on
pins 11-12 to select the secondary BIOS address (CC00:0).

WD1009V BIOS PINS 13-14 allow you to enable or disable the WD1009V BIOS. You most likely want
to enable the WD1009V BIOS, which is the default setting (pins 13-14 open). If you want to disable the
WD1009V BIOS, install a jumper shunt over pins 13-14.

IRQ PINS 15-16 and 17-18 function together to select the interrupt request (IRQ) address. Most
operating systems work with IRQ 14, which is the default setting.


If no jumper shunts are placed on pins 15-16 and 17-18, then IRQ 14 is selected. If a jumper shunt is
placed on pins 15-16 but not 17-18, IRQ 12 is selected. Leave pins 15-16 open and place a jumper
shunt on pins 17-18 to select IRQ 15. If jumper shunts are placed on both sets of pins, IRQ
11 is selected.

EISA DMA PINS 19-20 allow you to select the Direct Memory Access (DMA) channel in your EISA
system. When EISA DMA mode is enabled, it uses this DMA channel. The default setting of no
jumper shunt installed selects DMA channel 6. Install a jumper shunt on pins 19-20 to select DMA
channel 7.

HARD DISK CONTROLLER I/O ADDRESS PINS 21-22 select either the primary or secondary hard
disk controller I/O address. Leave pins 21-22 open to select the primary hard disk controller address
(1F0-1F7). Install a jumper shunt on pins 21-22 to select the secondary hard disk controller
address (170-177).

HARD DISK CONTROLLER PINS 23-24 enable or disable the hard disk controller. Leave pins 23-24
open to enable the hard disk controller. Place a jumper shunt on the pins to disable the hard disk
controller.

W6 JUMPER - FLOPPY CONTROLLER OPTIONS

This jumper block allows you to set a number of features related to your floppy controller. These
options apply only to the WD1009V-SE2 model.All default settings do not have a jumper shunt installed.

FLOPPY CONTROLLER PINS 1-2 allow you to enable or disable the floppy controller. Leave pins
1-2 open to enable the WD1009V-SE2 floppy controller. Place a jumper shunt on pins 1-2 to disable the
WD1009V floppy controller.

FLOPPY DMA PINS 3-4 allow you to select the Direct Memory Access (DMA) channel for the floppy
controller. To select DMA channel 2, leave pins open. To select DMA channel 3, install a jumper
shunt on pins 3-4.

FLOPPY CONTROLLER I/O ADDRESS PINS 5-6 select either the primary or secondary floppy
controller I/O address. Leave pins 5-6 open to select the primary floppy controller address (3F0-3F7).
Install a jumper shunt to select the secondary floppy controller address (370-377).

SPINDLE SPEED PINS 7-8 specify the spindle speed of 5 1/4" high density, 1.2MByte floppy drives.
Leave pins 7-8 open to designate a single-speed 1.2MB 5 1/4" drive. Install a jumper shunt over these
pins to designate a dual-speed 1.2MB 5 1/4" floppy drive.

W7 JUMPER - EISA AUTOCONFIGURATION

The W7 jumper allows you to enable or disable the EISA Autoconfiguration feature of your EISA
enhanced version of the WD1009V Controller. Refer to the Introduction to identify if your WD1009V
Controller is capable of EISA Autoconfiguration. Remove the jumper shunt if you want to disable the
EISA Autoconfiguration capability on your EISA-compatible WD1009V. Leave the jumper shunt on
pins 1-2 to enable the EISA Autoconfiguration feature.

CONFIGURING YOUR DISK DRIVES

OVERVIEW

This section provides information on configuring your ESDI hard disk drive(s) and floppy drive(s).
Refer to your drive installation or user manuals for specific jumper, connector, and switch locations.
Also refer to those manuals for exact configuration procedures. You need to know the types of cables
you plan to use for installation. These cables determine a number of the configuration selections on your
floppy and hard drives. If you are unsure of the types of cables you have, refer to the Introduction for
information on identifying your cables.


HARD DISK DRIVE CONFIGURATION


Your ESDI hard disk drive has jumpers, switches, and/or termination resistors that must be configured
before installing the WD1009V Controller in your system. The exact number of settings you need to
adjust or verify depends on the type and manufacturer of hard drive and computer you are
using.

There are three main hard drive settings that depend on the type of control cable you are using and the
position of the drive in your system:

þ Drive select number
þ Sectors per Track
þ Termination resistor setting

---------------------------------------------------------------------------
DRIVE SELECT NUMBER
---------------------------------------------------------------------------

The Drive Select number (DS#) selection depends on the type of control cable you use to connect the
hard drives to the WD1009V Controller. If you are using a 34-pin twisted control cable, and the first
drive is at the twisted end of the three-connector control cable, then both drives are
set to Drive Select 2. If the second drive is at the twisted end of the cable, then set both drives to Drive
Select 1.

If you are using a straight control cable, configure the first drive to Drive Select 1, and the second drive
to Drive Select 2.

Your actual drive select numbers depend on the starting Drive Select number of the jumpers. The Drive
Select numbers in this section are based on the jumpers starting at Drive Select 1. If your drive select
jumpers start at 0, then decrease the Drive Select numbers provided in this section by one.

--------------------------------------------------------------------------
SECTORS PER TRACK
---------------------------------------------------------------------------
ESDI hard drives must be configured for hard sector mode. The WD1009V does not support soft sector
mode. The drive sectors per track need to be set according to the speed of your drive:

þ for 10Mbit/sec drives, set the sectors per track for 35 SPT or less
þ for 15Mbit/sec drives, set the sectors per track for 53 SPT or less
þ for drives over 15Mbit/sec, refer to your drive documentation for the recommended sectors per
track setting
---------------------------------------------------------------------------
TERMINATION RESISTOR SETTING
---------------------------------------------------------------------------

For a single drive installation, the termination resistor needs to be installed on the drive.

For a dual drive installation, the drive termination resistor must be installed on the last physical drive
installed in a daisy-chain (three connector cable) configuration. Remove the termination resistor from
the middle drive at the center of the control cable. Disable the resistor by adjusting the jumper setting,
or by physically removing the resistor. Refer to your drive installation documentation for information on
properly removing the termination resistor, and on configuring the drive for your
system installation.

You can install three or four hard drives in your system by using two WD1009V Controllers. In this
installation, each WD1009V Controller interfaces two ESDI drives. Most operating systems currently
do not support more than two hard drives in a system. This installation will probably require software
drivers. Refer to your operating system or third party software vendor for information on special
software drivers. Refer to Appendix B for information on installing four hard drives in your system with
the WD1009V.

Once the drives are correctly configured, you can install them in your system according to the drive
installation instructions located in your drive installation manual. It may be helpful to mark each drive
to indicate which drive is the first drive and which is the second drive. Be sure that the cable is
correctly connected to each drive before installing the WD1009V Controller.

FLOPPY DISK DRIVE CONFIGURATION

The WD1009V-SE2 Controller can interface up to three floppy drives with one cable. If you are
connecting two floppy drives to the WD1009V Controller, floppy drive configuration is similar to hard
disk configuration when specifying the drive select numbers. The Drive Select number depends on the
type of floppy cable used and the position of drives on the cable. Most floppy cables are twisted cables.

If you are using a 34-pin twisted floppy cable, and the first drive is at the twisted end of the
three-connector floppy cable, then both drives are set to Drive Select 2. If the second drive is at the
twisted end of the cable, then set both drives to Drive Select 1.
Your actual drive select numbers depend on the starting Drive Select
number of the jumpers. The Drive Select numbers in this section are based
on the jumpers starting at Drive Select 1. If your drive select jumpers
start at 0, then decrease the Drive Select numbers provided in this
section by one.

If you are using a straight floppy cable, configure the first drive to Drive Select 1, and the second drive
to Drive Select 2.

If you plan to install three floppy drives in your system, you need a four-connector floppy cable and
software drivers that support this type of installation. There are two steps involved in successfully
installing three floppy drives in your system for use with the WD1009V Controller: configuration and
installation. This section describes the necessary configuration information. Installing The WD1009V
Controller describes the installation information needed to install the WD1009V, and prepare the floppy
drives for use.

---------------------------------------------------------------------------
CONFIGURATION
---------------------------------------------------------------------------

If you are installing three floppy drives with an end-twisted floppy cable, the configuration is similar to
the standard configuration of twisted floppy cable for two drives. The additional connector for the third
floppy drive is closest to the controller connector.

The W2 jumper on the WD1009V Controller should have a jumper placed on pins 2-3 to select an
end-twisted cable. Drive 1 is connected to the end connector, drive 2 to the middle floppy connector,
and drive 3 to the connector closest to the controller connector. In this installation, drive 1 and 2 are set
to Drive Select 2, and drive 3 is set to Drive Select 4. (Select Drive Select 4 if the drive select jumpers
begin at Drive Select 1, or select Drive Select 3 if the drive select jumpers start at Drive Select 0.)

If you are using a center-twisted floppy cable, the third floppy drive is placed at the end of the cable.
Using this cable, drive 3 is connected to the end floppy connector, drive 1 is connected to the middle
floppy connector, and drive 2 is connected to the connector closest to the controller connector. Again,
drive 3 is set to Drive Select 4, and drives 1 and 2 are set to Drive Select 2.

The W2 jumper on the WD1009V Controller should have a jumper shunt placed on pins 1-2 to select the
center-twisted cable. (Again, select Drive Select 4 if the drive select jumpers begin at Drive Select 1, or
select Drive Select 3 if the drive select jumpers start at Drive Select 0.)

Refer to your floppy drive installation or user manual for instructions on setting jumpers, drive select
options, and termination resistors.

---------------------------------------------------------------------------
TERMINATION RESISTOR SETTING
---------------------------------------------------------------------------

For a single floppy drive installation, the termination resistor needs to be installed on the drive. When
installing two or three floppy drives, the termination resistor must be installed on the last physical drive
installed in a daisy chain configuration. Remove the termination resistor from the middle drives at the
center of the cable. Disable the resistor by adjusting the jumper setting, or by physically removing the
resistor.

Refer to your drive installation documentation for information on properly removing the termination
resistor, and on configuring the drive for your system installation.

The installation of three floppy drives in your system will probably require software drivers. Refer to
your operating system or third party software vendor for information on special software drivers.

Once the drives are correctly configured, you can install them in your system according to the drive
installation instructions located in your drive installation manual. It may be helpful to mark each drive
to indicate which drive is the first drive, which is the second drive, and so on. Be sure that the cable is
correctly connected to each drive before installing the WD1009V Controller.

INSTALLING THE WD1009V CONTROLLER
This section provides the steps necessary to install your WD1009V Controller in your PC/AT system.

þ Step One: Preparing for Installation þ Step Two: Locating the Expansion Slot

þ Step Three: Connecting the Hard Drives þ Step Four: Connecting the Floppy Drives

þ Step Five: Installing the Activity LED þ Step Six: Installing the WD1009V Controller

STEP ONE:
PREPARING FOR INSTALLATION

þ The controller, hard disk drives, and floppy drives are correctly configured

þ Your hard disk and floppy drives are correctly installed according to the drive installation manuals

þ A termination resistor is installed on the last hard drive and last floppy drive

þ Connect the power supply connector to the drives

þ Any existing hard drive and floppy drive controller is removed or disabled from your system.

STEP TWO:
LOCATING THE EXPANSION SLOT

The WD1009V Controller fits into a 16-bit expansion slot or 32-bit EISA expansion slot inside your
computer. Once the cover is off the computer, you will recognize an area toward the back of the
computer that has expansion slots available for peripheral cards. This area may already have cards
installed, such as a video graphics card, or serial port card. When installing the WD1009V, it is best to
select the expansion slot that is closest to the drives in your system.

There are two possible types of expansion slots: a motherboard expansion slot, and a vertical
side-mounted expansion slot. In this installation, the motherboard is located beneath the expansion slot
area, and the cards are seated on the motherboard.

Slimmer systems may have side-mounted vertical expansion slots. Once you locate the desired
expansion slot, remove the expansion slot cover by loosening the screw that holds the cover in place.

The inside of your computer may differ from the illustrations in this manual. Refer to your computer
installation or user manual for the exact location of your system components.

STEP THREE: CONNECTING THE HARD DRIVES

Note: Be sure to align pin 1 on the cable connectors to pin 1 on the drive connector, and on the
controller connector. Pin 1 on the cable is indicated by a notch on the connector, or the pin 1 line on
the cable is color coded. Damage may occur if the cables are not properly connected.

This section provides information on connecting your hard disk drives to the WD1009V Controller.
During connection, do not mistake the hard disk drive control cable for the floppy cable. Also make
sure that the drives are installed properly before connecting them to the WD1009V Controller.

To connect the hard drives to the controller:

1. Be sure the drives are properly cabled together with the daisy chain cable when installing two hard
drives.

2. Connect the 34-pin control cable connector from the hard drives to the J5 connector. Be sure to
align pin 1 on the cable connector to pin 1 on the controller connector, and drive connectors.

Do not confuse the hard drive daisy chain cable with a floppy daisy chain cable. They are not
interchangeable.

3. Connect the 20-pin data cable from the first drive to the J4 connector on the controller connector.
Align pin 1 to pin 1 on the drive and controller. The first drive is the boot drive.

4. If you are installing two drives, connect the second drive (drive 1) data cable to the J3 controller
connector. Drive 1 is the second or D: drive in a dual hard drive installation.

5. Connect the power supply connector to the drives.

STEP FOUR: CONNECTING THE FLOPPY DRIVES

Note: Skip this section if you are disabling the floppy controller or are installing the WD1009V-SE1
Controller.

This section provides information on connecting your floppy disk drives to the WD1009V-SE2
Controller. During connection, do not mistake the hard disk drive control cable for the floppy cable.
Also make sure that the drives are installed properly before connecting them to the WD1009V
Controller.

To connect the floppy drives to the controller:

1. Be sure the drives are properly cabled together with the daisy chain
cable when installing two or more floppy drives.

2. Connect the 34-pin floppy cable connector from the floppy drives to the J1 connector. Be sure
to align pin 1 on the floppy cable connector to pin 1 on the controller connector and to the drive
Connectors. Do not confuse the hard drive daisy chain cable with a floppy daisy
chain cable. They are not interchangeable.

3. The hard drive connections are also displayed since the hard drives are connected to the
controllerbefore the floppy drives are connected.

4. Route the floppy and hard drive cables in your system between the drive area and selected
controller expansion slot. Do not force the cables between system components. The cables
should not obstruct any air flow paths or rest between the controller and computer cover.


STEP FIVE:INSTALLING THE ACTIVITY LED

This is an optional step. If your system provides an activity light-emitting diode (LED) indicator for
your hard drives, install the connector into the J6 connector on the WD1009V Controller.

STEP SIX: INSTALLING THE WD1009V CONTROLLER

Once all of the drives are correctly cabled to the WD1009V, you are ready to install the controller in
your system.

1. Carefully slide the controller board into the selected expansion slot.

2. Press evenly on the edges of the controller board as you insert it into the expansion slot. You
will feel the controller slip into place and seat firmly in the slot.

3. After the board is firmly seated in the expansion slot, secure the controller to the computer by
tightening the screw on the expansion slot cover.

4. Make sure that all cables and power cords inside the computer are reattached beforeclosing the
computer.

5. Replace and install the computer cover according to the instructions provided in your computer
installation manual.

6. Attach all cables and connectors to the back of the computer. Plug in the power cord.

The WD1009V is now installed. You now need to prepare the drives for use by performing some setup
routines.

PREPARING THE WD1009V FOR USE

Your drive needs to be prepared for use. You will need your operating system diskettes for this phase
of installation. This section describes the disk preparation procedures for your system using the
WD1009V BIOS routine and DOS operating system. If you are using a different operating system, refer
to your operating system documentation for set up procedures.

The WD1009V BIOS routine allows you to: þ perform a low-level format þ read and mark the hard
drive defect tables þ perform a read verify þ perform a surface analysis þ show the configuration
information þ set the BIOS options and drive parameters

Your DOS Debug utility allows you to access the WD1009V BIOS set up routines. The set up routines
are displayed in an easy-to-use menu on your screen.

ACCESSING THE WD1009V BIOS MAIN MENU
The WD1009V Setup Screen is accessed through the DOS Debug utility.

1. Turn the system power on.
2. Boot the system from the bootable DOS diskette.
3. Insert the diskette that contains the Debug utility into drive A:.
4. Type Debug at the screen prompt. Press [Return].
5. A dash (-) prompt is displayed. Type g=C800:5. This tells the system to access the WD1009V
BIOS routine from the Controller. If you set the WD1009V BIOS to the secondary BIOS address,
(jumper W5 with a jumper shunt installed on pins 11-12), type g=CC00:5.

6. Press [Return]. The WD1009V BIOS routine finds the drive parameters and displays the BIOS Main

Figure 13: Drive Translation Tables

The order and types of translation tables displayed on your screen are similar to those shown in Figure
13.

The following five choices are offered to provide flexibility for your operating system and drive
configuration. We recommend you use the third table for ESDI drives with less than 528Mbytes, and
the fifth table for drives over 528Mbytes. If you select the fifth table, you must enable WD1009V BIOS
INT 13. Refer to BIOS Setup Options for more information.

The first table lists the physical parameters but truncates the number of cylinders to a maximum of 1023,
which could cause a loss of capacity on a large drive.

The second table truncates the number of cylinders to 1023, increases the number of heads to 16, and
decreases the sectors per track to 17.

The third table allows the DOS maximum number of cylinders, heads, and sectors per track. This table
affords a maximum of 528MBytes.

The fourth table lists the actual physical parameters for the drive. Select this translation table only if
you have an operating system or a custom driver that supports the physical drive parameters of your
drive.
The fifth drive translation table allows you to use the full capacity of drives with more than 528MBytes.
You need to enable the WD1009V INT 13 to use this table.

---------------------------------------------------------------------------
SELECTING THE TRANSLATION TABLE
---------------------------------------------------------------------------

To select a translation table, use the up and down arrow keys to move through the tables listed. Place
the pointer that appears on the left side of the screen in front of the desired translation table. Press
[Return] to select the translation table for each drive. If there is another drive installed, the screen
displays the translation tables for that drive. Select the appropriate translation table and press [Enter].
This process continues until all installed drives have an assigned translation table.

If you only have one drive installed, or when you have completed selecting the translation table for the
last drive installed, press [Return] a few times to exit the BIOS Menu. The system automatically
reboots.

PARTITIONING

You need to partition the hard disk once the system is rebooted. The Fdisk program on your DOS
diskette sets up partitions on your drive.

To partition your ESDI drives:
1. Boot from a bootable DOS diskette.
2. Install the DOS diskette that contains the Fdisk program.
3. Type Fdisk at the prompt.
4. Press [Enter].
5. Follow the instruction displayed on screen to partition your ESDI
drives. Be sure to make the boot partition the active partition in
order to boot from your hard drive.

For more information on partitioning and Fdisk, refer to your operating system documentation.

HIGH-LEVEL FORMATTING

High-level formatting installs the operating system and prepares your disk to accept files.

To perform a high-level format:
1. Reboot from a bootable diskette.
2. Install the DOS diskette that contains the Format program in drive A:.
3. At the prompt, type Format C:/S to install DOS on the C: partition.
4. Press [Return].
5. Enter Y to format.

Once the format procedure is complete, you can use your hard drive in your system, and boot from the
hard drive. Remove the DOS diskette from drive A:. Press [Ctrl], [Alt], and [Del] simultaneously to
reboot your system from the first hard drive.


Once you reboot your system, the screen should display the C: prompt. If this does not occur, or if you
encounter error messages, refer to your operating system manual or the Troubleshooting section for
information on resolving problems.
Your WD1009V installation is now complete and your system is ready for use.


TROUBLESHOOTING

Note: If your system CMOS set up is erased and the WD1009V BIOS was used to low-level format
your hard drive, use your system configuration utility to reset the hard drive type to Type 1 for each
ESDI drive.

Figure A-1: WD1009V EISA Controller, EISA Enhanced Version


Figure A-1 shows the WD1009V with the chip installed at location U51. The following instructions are
for the EISA enhanced version of the WD1009V only.

Most systems require jumper W4 to be left open so that the WD1009V is always enabled. Install a
jumper shunt on jumper W7, pins 1-2 to enable the EISA Autoconfiguration features of the WD1009V
Controller.

Remember that jumpers W1, W2, W3, W4, and W7 need to be set manually. They cannot be
controlled through the autoconfiguration.

To use your EISA system's Autoconfiguration, you need to load the WD1009V-SE1/SE2
Autoconfiguration files on to your system during configuration. These files are on a diskette included
with the enhanced controller. They may also be downloaded from the Technical Support Bulletin Board.

Follow your EISA system configuration utilities manual for instructions on configuring your EISA
system.

APPENDIX B:
INSTALLING THREE OR FOUR HARD DRIVES


You can install up to four hard drives in your system with the use of two WD1009V Controllers. Each
WD1009V Controller can interface two ESDI drives.

Most operating systems do not support more than two hard drives. This installation will probably
require software drivers. Refer to your operating system or third party software vendor for more
information.

When installing three or four hard drives, each pair of drives are cabled according to the installation
instructions in Installing The WD1009V Controller. Connect two drives to each controller.

When preparing and installing the controllers and drives in your system, you need to determine which
controller will be designated as the second controller. Configure the second controller to the secondary
I/O Address and DMA channel. Also configure the second controller with a different IRQ address. The
BIOS and floppy controller must both be disabled on the second controller.

When preparing the drives for use through the BIOS options in the WD1009V BIOS Main Menu, be
sure to enable the Power Up Scan for Drives 2 & 3 option. This enables the power up scan for your
third and fourth drives.
