WESTERN  CAVIAR  INSTALLATION GUIDE 79-850086-003 SO225 11/98

 Jumper Settings
 ===============
 Western Digital hard drives have a jumper block (J8) located next to
 the 40-pin IDE connector on the hard drive. These jumpers select
 options on the hard drive. Your hard drive may have either a 6-pin or
 10-pin jumper block. The first 6 pins on each jumper block are
 identical. The additional four pins on the 10-pin jumper block are
 reserved for future enhancements.

 The Western Digital hard drive is factory set for single drive
 installation with a jumper in the neutral storage position (across
 pins 5-3 or 6-4).

 The Cable Select jumper option is usually not required. It needs
 special support in your system hardware.


 Single Hard Drive Installations
 -------------------------------
 If installing your new Western Digital hard drive as the only hard
 drive in your system, leave the jumper in the neutral storage
 position for possible future use. Jumpers are not required for single
 hard drive installations.


 Dual Hard Drive Installations
 -----------------------------
 If installing your new Western Digital hard drive with an existing
 drive on the same IDE interface cable, use a jumper to designate the
 master (C:) and the slave (D:) drive.


 Neutral storage placement in this position, the jumper has no effect
 on hard drive operation.

 If installing your new Western Digital hard drive with an existing
 drive on separate IDE interface cables, leave the jumper in the
 neutral storage position for possible future use. The system
 recognizes each drive as a single, stand-alone drive. Master/slave
 jumper settings are only used when there are two devices on the same
 IDE interface cable.


 Note for Apple Users: Apple systems do not support master/slave
 configurations. You can only install one EIDE hard drive to each
 port.

 This jumper should be repositioned to select the following options:

 - To designate the Western Digital hard drive as the master drive in
   a two-drive system, place the jumper on pins 5-6.

 - To designate the Western Digital hard drive as the slave drive in a
   two-drive system, place the jumper on pins 3-4.

 If installing your new Western Digital hard drive with a non-Western
 Digital hard drive, obtain jumper configuration information from the
 EZ-Drive software diskette, or your original drive manufacturer.

 Setting the Jumper: Carefully place the jumper over the two pins.
 Push the jumper into place until it is firmly seated against the
 base of the jumper block.

    +6-4-2+                           +6-4-2+

 The Caviar can be assigned as either a single, master, or slave
 drive.


 Single Drive Mode
 -----------------
 If you are installing the Caviar drive as the only intelligent drive
 in the system, you do not need install jumpers on the J8 connector.
 This is considered a standard single drive installation, and no
 jumpers are required. Note that even with no jumper installed, the
 Caviar checks the DRIVE ACTIVE/SLAVE PRESENT (DASP) signal to de-
 termine if a slave intelligent drive is present.

 If you have a dual installation (two intelligent drives), you must
 designate one of the drives as the master and the other as the slave
 drive. The jumper pins on the J8 connector need to be configured for
 the dual installation.


 Master Drive Mode
 -----------------
 To designate the drive as the master, place a jumper shunt on pins
 5-6. With the Caviar configured as the master drive, the Caviar
 assumes that a slave drive is present. The jumper on pins 5-6 is
 optional if the slave drive follows the same protocol (Common Access
 Method AT Bus Attachment) as the Caviar.


 Slave Drive Mode
 ----------------
 To designate the drive as the slave, place a jumper shunt on pins
 3-4. When the Caviar is configured as the slave drive, the Caviar
 delays spin up for three seconds after powerup reset. This feature
 prevents overloading of the power supply during powerup.


 Cable Select (CSEL)
 -------------------
 Caviar also supports the CSEL signal on the drive cable as a drive
 address selection. Place a jumper shunt on pins 1-2 to enable this
 option. When enabled, the drive address is 0 (Master) if CSEL is low
 or 1 (Slave) if CSEL is high.

 The drive will operate in all axis (6 directions).


 HARDWARE INSTALLATION
 ---------------------
 Before you begin, gather these supplies:
 - Computer system manual

 - Operating system installation disks or CD-ROM

 - Operating system manual

 - Small Phillips screwdriver and flat-blade screwdriver

 - Bootable DOS disk or Windows 95 or 98 startup disk


 Be sure to write down your serial and model numbers and the CCC
 code. These numbers are located on the drive label.


 Create a Bootable DOS Disk
 --------------------------
 For single hard drive installations, you must have a bootable DOS
 disk to install your new hard drive with EZ-Drive. Disk 1 of your
 standard DOS installation disk set is a bootable disk. If you do not
 have your original DOS installation disks, you can create a bootable
 DOS disk if you have a bootable C: hard drive.

 1. Insert a blank floppy disk into drive A.

 2. At the C: prompt, type format a:/s. Press ENTER.
    Create a Windows 95 or 98 Startup Disk

 For Windows 95 or 98 systems, you must have a bootable DOS or
 Windows 95 or 98 Startup disk to install your new hard drive with
 EZ-Drive. If using Windows 95 or 98, you should create a Windows
 95 Startup disk. To create a Windows 95 or 98 Startup disk you must
 have a bootable C: hard drive.

 1. Insert a blank floppy disk into drive A.

 2. From Windows 95 or 98, click My Computer.

 3. Click Control Panel.

 4. Click Add/Remove Programs.

 5. Select the Startup Disk tab.

 6. Click Create Disk. Follow the prompts to create a Windows 95
    Startup disk.


 Back Up Existing Drives
 -----------------------
 Protect your data by backing up your existing hard drive before
 installing your new Western Digital hard drive. Save the data to
 removable media such as floppy disks or tape. Most operating systems
 include a backup utility. Consult your operating system or utilities
 documentation for backup instructions.


 Unpacking and Handling the Hard Drive
 -------------------------------------
 Western Digital hard drives are precision instruments and should be
 handled with care during unpacking and installatiom. Hard drives are
 typically damaged by rough handling, shock, vibration, or
 electrostatic discharge (ESD). Be aware of the following precautions
 when unpacking and installing your Western Digital hard drive.

 - Do not unpack your hard drive until you are ready to install it.
   After your WD hard drive is unpacked, place the drive on the static
   shielding bag on a clean, level, padded work area. Your Western
   Digital hard drive comes packaged in a static shielding bag.

 - Save the packing materials in case you need to return your hard
   drive. Shipping your hard drive in anything other than the original
   packaging or WD supplied or approved materials will void your
   warranty.

 - To avoid ESD problems, ground yourself by touching the metal
   chassis of the computer before handling the hard drive. Articles of
   clothing generate static electricity. Do not allow clothing to come
   in direct contact with the hard drive or circuit board components.

 - Handle the hard drive by the sides only. Avoid touching the circuit
   board components.

 - Do not drop or knock the hard drive.

 - Before installation, do not stack hard drives or stand your Western
   Digital hard drive on its edge. You can, however, mount your hard
   drive horizontally or vertically.

 - Do not remove the tape seal or any labels from the drive; the
   warranty will be void.


 Open Your Computer
 ------------------
 1. Turn off your system.

 2. Discharge static electricity by touching the metal chassis of the
    computer.

 3. Unplug your computer.

 4. Remove the computer's outside cover. Consult your computer
    system manual for details. Be sure to keep all screws and other
    parts together for easy reassembly.


 Removing Existing Hard Drives
 -----------------------------
 If replacing an existing drive, follow these instructions.

 IMPORTANT
 Be sure to turn off the system power and unplug the power.

 1. Disconnect the power cord and IDE interface cable.

 2. Remove screws and slide the hard drive out of the drive bay.
    Handle the hard drive with care. Be careful not to scratch, tear,
    or remove the tape seal on the drive; this will void the warranty.

 If installing your new Western Digital hard drive with an existing
 drive on separate IDE interface cables, leave the jumper in the
 neutral storage position for possible future use. The system
 recognizes each drive as a single, stand-alone drive. Master/slave
 jumper settings are only used when there are two devices on the same
 IDE interface cable.

 Note for Apple Users: Apple systems do not support master/slave
 configurations. You can only install one EIDE hard drive to each
 port.

 If installing your new Western Digital hard drive with a non-Western
 Digital hard drive, obtain jumper configuration information from the
 EZ-Drive software diskette, or your original drive manufacturer.


 Mounting Hardware
 -----------------
 Inspect the bay to determine whether it is a 3.5-inch or 5.25-inch
 bay. The WD hard drive fits into a 3.5-inch bay. If installing the
 WD hard drive i- a 5.25-inch bay, you must install 5.25-inch mounting
 hardware. If you do not have mounting brackets, contact your system
 manufaturer, your local computer dealer, or call Western Digital's
 technical support.


 Drive Rails (Optional)
 ----------------------
 Some computer systems have 5.25-inch drive bays that require unique
 sliding drive rails to complete the hard drive installation. Because
 each system manufacturer has a different type of drive rail, rails
 are not included with WD hard drives.

 If your system requires drive rails, contact the computer system
 manufacturer. The following list provides phone numbers for common
 system manufacturers.


 Installing your new WD hard drive
 ---------------------------------
 IMPORTANT
 Your system must be turned off before connecting or disconnecting the
 power supply to the drive.

 1. Thread the cable through the empty drive bay and slide in the
    WD hard drive.

 2. Attach the end of the 40pin IDE interface cable to the 40-pin
    connector on the back of the WD hard drive. Match pin socket 1 on
    the IDE cable (indicated by a color stripe on the cable) to pin 1
    on the Western Digital hard drive.

    Note for Apple Users: Use an Apple supplied interface cable only.

    Pin 40 on an Apple supplied interface cable is indicated by a
    color stripe on the cable.

 3. Attach the computer system power supply cable to the 4 pin
    power connector on the back of the Western Digital hard drive.
    The 4 pin connector is keyed to ensure proper insertion.

 4. Single Installations: Attach the end of the 40 pin IDE interface
    cable from the Western Digital hard drive to the 40 pin connector
    on the motherboard or controller card. Match pin socket 1
    (indicated by a color stripe on the cable) on the IDE interface
    cable (next to the drive power connector) to pin 1 on the
    motherboard or controller card.


 Dual Installations
 ------------------
 Connect the two hard drives by using a 40 pin, three-connector IDE
 interface cable. Match pin socket 1 on the 40 pin, three-connector
 IDE cable to pin 1 on the drive's connector.

 5. Mount the WD hard drive in the drive bay using the four mounting
    screws provided. For proper grounding, be sure to use all four
    screws.

    If your system does not have an extra power connector, purchase a
    Y-adapter from your computer dealer.

 6. Check all cable connections. Replace the system cover.

 7. Plug in your computer.

 8. See the EZ-Drive Software Installation section for hard drive
    setup instructions.

WESTERN  CAVIAR  INSTALLATION GUIDE 79-850086-003 SO225  11/98


 SOFTWARE INSTALLATION
 ---------------------
 Before partitioning and formatting your new hard drive, you need to
 configure your system BIOS. Your computer system provides an initial
 setup ability (CMOS Setup) that allows you to tell the system what
 type of hardware you are using.


 Configuring the System BIOS
 ---------------------------
 Each system BIOS is different. The information supplied here is not
 meant to be followed step-by-step; it is provided only as a
 guideline.

 Refer to your system manual for details.

 1. Enter your CMOS setup program (sometimes called the Setup
    program). Refer to your system manual for instructions

    IMPORTANT
    If your system does not respond (locks up) on inintial boot, see
    Operating System and System BIOS Limitations.

 2. Enable options such as LBA or Translation Mode. If you do not have
    either option, you need to use EZ-Drive to install your new hard
    drive, upgrade the system BIOS, or install an EIDE controller card
    with onboard BIOS that supports the full drive capacity.

 3. Select an auto config drive type. The full capacity of your drive
    should display. If your system BIOS does not have an auto config
    drive type, select user defined and enter 1023 cylinders, 16
    heads, and 63 sectors for the drive parameters. Selecting user
    defined ensures that EZ-BIOS will install on your system.

    If your system BIOS does not have auto config or user defined,
    select Type 9. Selecting Type 9 ensures that EZ-BIOS will install
    on your system.


 EZ-Drive Software Overview
 --------------------------
 EZ-Drive is a software utility that quickly and easily partitions and
 formats your new hard drive. If needed, EZ-Drive installs added code
 in the boot sector of your hard drive if it determines that your
 system BIOS does not support the full capacity of your hard drive.

 EZ-Drive software is included with the Western Digital hard drive to:

 - Overcome the 8.4 GB, 2.1 GB, and 528 MB system BIOS limitantions.

 - Partition and format your new hard drive.

 - Copy system files needed to boot your new hard drive.

 - Copy the contents of an existing hard drive onto your new hard
   drive (optional).

 If you did not receive EZ-Drive software, you can download it from
 the Western Digital web site at WWW.WESTERNDIGITAL.COM.


 Operating System Compatibility
 ------------------------------
 You Can use EZ-Drive software with these operating systems:
 - DOS 5.0 and above

 - Windows 98

 - Windows 95

 - Windows NT 3.51 and 4.0 (do not use alternate jumper settings
   for hard drives >4.2 GB )

 - Windows 3.1x and Windows for Workgroups 3.11

 - OS/2 Warp 3.0 and 4.0

 IMPORTANT
 Windows NT 3.51 and 4.0 and OS/2 Warp 3.0 and 4.0 DO NOT support the
 EZ-Drive floppy boot protection scheme.

 If using one of these operating systems, you must disable floppy boot
 protection immediately after installing EZ-Drive. You CANNOT use
 EZ-Drive with these operating systems:

 - Macintosh

 - Novell NetWare

 - Unix

 If using a Macintosh computer, partition and format your new hard
 drive with the Apple Drive Setup software. If using Unix or Novell
 NetWare, consult your operating system manual to partition and
 format your hard drive.


 EZ-BIOS
 -------
 EZ-BIOS is code that installs on the boot sector of the hard drive if
 your system BIOS does not support the full capacity of your hard
 drive. EZ-BIOS helps your system overcome the 8.4 GB, 2.1 GB, and
 528 MB barriers. See Operating System and System BIOS Limitations.

 EZ-Drive determines if your system BIOS as set supports the full
 capacity of your hard drive. If it does, EZ-Drive only partitions and
 formats the hard drive; it does not install EZ-BIOS. If it does not,
 EZ-Drive partitions and formats the hard drive and installs EZ-BIOS
 on the boot sector of the hard drive.


 Partition and Format
 --------------------
 EZ-Drive automatically partitions and formats your hard drive. You
 can accept the EZ-Drive default partition sizes or create custom
 partitions.
 Since it is difficult to determine if your system BIOS supports 8.4
 GB or larger hard drives, we recommend using EZ-Drive 9.06W or later
 versions. It is a fast and easy way to partition and format your new
 hard drive.

 IMPORTANT. DOS, Windows 3.1x, and early versions of Windows 95 use
 FAT16 file systems which have a 2.1 GB partition limit. You must
 create multiple partitions on hard drives larger than 2.1 GB.


 Copying System Files
 --------------------
 EZ-Drive copies system files needed to boot your new hard drive.
 These files can be copied from your existing hard drive or diskette.
 Copying Data from an Existing Hard Drive to a New Hard Drive
 For DOS, Windows 3.1x, Windows 95, Windows 98, and Windows
 NT systems, use this feature to copy the contents (operating systems,
 data, hidden files, and programs) of an existing hard drive to your
 new hard drive. If you use this feature, you do not need to reinstall
 your operating systems and software programs on your new hard drive.

 Note: EZ-Drive cannot copy OS/2 HPFS and Windows NT NTFS
       partitions (some OS/2 and Windows NT systems have these
       partition types).


 Software Compatibility
 ----------------------
 Converting Ontrack Disk Manager Partitions to EZ-Drive
 Partitions: Ontrack Disk Manager and EZ-Drive cannot coexist in
 the same system. If your existing drive has Ontrack Disk Manager
 installed, use the EZ-Drive Fully Automatic Install to set up your
 new hard drive and convert Ontrack Disk Manager boot code to
 EZ-BIOS.

 Even though EZ-Drive converts Ontrack Disk Manager partitions to
 EZ-BIOS partitions without data loss, be sure to back up your
 existing hard drive before proceeding.

 Data Compression Software: EZ-Drive is compatible with Stacker,
 Drivespace, and Doublespace disk compression utilities. Other data
 compression software may not be compatible. Always back up your
 data before using any data compression software.

 Diagnostic Software: Some system manufacturer diagnostic software
 may be incompatible with EZ-Drive.

 Hard Disk Device Drivers: Products that use their own hard disk
 device drivers such as third-party disk controllers and some caching
 controllers may not be compatible with EZ-Drive.

 Memory Managers: EZ-Drive is fully compatible with the standard
 memory managers that come with DOS and Windows. However, EZ-Drive
 loads in conventional memory and may not be compatible with some
 third-party memory managers.


 Using EZ-Drive Software
 -----------------------
 Single Hard Drive Installation
 ------------------------------
 Follow the steps outlined below to set up your hard drive for use in
 a one-drive system. These steps are a guideline. Depending on your
 system and hard drive, the EZ-Drive screens you see may be different
 than those presented here.

 If installing your hard drive in a multiple-drive system, see the
 Adding Your New Hard Drive with an Existing Hard Drive section.
 IMPORTANT: Windows NT 3.51 and 4.0 and OS/2 Warp 3.0 and 4.0 DO NOT

 TROUBLESHOOTING
 ---------------
 This section lists procedures to help resolve problems that you may
 encounter when installing the Western Digital hard drive.

 - Refer to your system documentation to be sure that you followed
   the setup procedures correctly.

 - Make sure that you partitioned and formatted the EIDE drive and
   any additional drive with the EZ-Drive installation software. Refer
   to your operating system documentation to check these procedures.

 - If using DOS 3.3 and above, be certain to make one partition
   active during formatting.

 - Check the physical installation of your system to make sure that:
   - Jumper selections on the drive are correct for your installation.

   - Cables are correctly connected and seated.

   - Adapter card, if required, is properly seated, connected, and
     configured.

   - Power is properly connected to your system and the system is
     plugged in.


 Operating System and System BIOS Limitations
 --------------------------------------------
 Computer operating systems and system BIOSs have separate limitations
 that are related to specific hard drive capacities. Three capacity
 points that can affect how your operating system and system BIOS
 support your hard drive are 8.4 GB, 2.1 GB, and 528 MB. A brief
 description of these limitations follows.

 8.4 GB Barrier: There is an 8.4 GB hard drive limitations on some
 traditional system BIOSs. To access the full capacity of 8.4 GB and
 larger hard drives, your system BIOS must support extended BIOS
 functions, and your operating system must recognize extended BIOS
 functions. It is difficult to determine if your system BIOS supports
 8.4 GB or larger hard drives. We recommend using EZ-Drive 9.06W
 or later to ensure support of the full capacity of your hard drive.
 2.1 GB Barrier: Some computer systems built before early 1996 do
 not support hard drives with more than 4095 cylinders (hard drives
 larger than 2.1 GB), unless you update the system BIOS, install an
 EIDE controller card with onboard BIOS, or install third-party
 software such as EZ-Drive.

 528 MB Barrier: Most computer systems built before August 1994 do
 not support hard drives larger than 528 MB, unless you update the
 system BIOS, install an EIDE controller card with onboard BIOS, or
 install third-party software such as EZ-Drive.

 To determine if your system BIOS supports the full capacity of your
 hard drive, EZ-Drive compares the system CMOS settings to the
 actual drive size. If the values match, EZ-Drive only partitions and
 formats the hard drive; it does not install EZ-BIOS. If the values do
 not match, EZ-Drive partitions and formats the hard drive and
 installs EZ-BIOS on the boot sector of the hard drive.


 Operating System and System BIOS Limitations for 8.4 GB and
 Larger Hard Drives
 -------------------------------------------------------------
 The following is required to access the full capacity of an 8.4 GB or
 larger hard drive:

 - A system BIOS that supports extended functions

 - an operating system that recognizes extended BIOS functions

 The limitations of your system BIOS and your operating system
 combined determine your overall system limitation. For example, if
 your operating system recognizes extended BIOS functions, but your
 system BIOS has a 2.1 GB drive barrier, you are limited to your
 system BIOS's 2.1 GB drive barrier. Conversely, if your operating
 system does not recognize extended BIOS functions, but your system
 BIOS supports 8.4 GB hard drives, you are limited to your operating
 system's capability. Your system limitation is based on the lowest
 functioning barrier.

 Since it is difficult to determine if your system BIOS supports your
 8.4 GB or larger hard drive, we recommend using EZ-Drive 9.06W to
 support the full capacity of your hard drive. Another option is to
 upgrade your system BIOS. A properly upgraded system BIOS will
 support the full capacity of your hard drive if used with an
 operating system that recognizes extended BIOS functions. Contact
 your system manufacturer for more information.

 Operating systems that recognize extended BIOS functions:
 - Windows 95

 - Windows 98

 Operating systems that do not recognize extended BIOS functions.
 - DOS 6.xx and earlier

 - Windows 3.1x

 - Windows NT

 - Novell NetWare

 - OS/2 Warp

 Operating System Limitations and Exceptions
 DOS 6.xx and earlier
 Windows 3.1x
 8.4 GB maximum capacity limit. Hard drive capacities
 larger than 8.4 GB are recognized as 8.4 GB.

 Windows NT Windows NT 4.0 with Service Pack 3 supports hard
 drive capacities larger than 8.4 GB.

 Novell NetWare Novell NetWare 4.11: Drivers are available to support
 capacities larger than 8.4 GB.

 Novell NetWare 5 supports 8.4 GB and larger hard drives.

 OS/2 Warp Requires patch to support 8.4 GB or larger hard drives.


 System BIOS Limitations for Hard Drives Larger Than 2.1 GB
 -----------------------------------------------------------
 IMPORTANT
 If you installed a 2.5 GB or larger hard drive and your system does
 not respond (locks up) on initial boot, read this section.

 Hard drives larger than 2.1 GB have more than 4095 cylinders. On
 some systems, the system BIOS cannot properly recognize hard drives
 with more than 4095 cylinders.

 You will know if your system BIOS has this limitation after
 installing your drive if:

 - Your operating system shows a much smaller drive capacity than
   the actual drive capacity.

 - Your system locks up on initial boot, preventing you from accessing
   CMOS setup.


 Operating System Shows a Much Smaller Capacity
 ----------------------------------------------
 If your operating system shows a much smaller drive capacity, use
 EZ-Drive to overcome the 2.1 GB BIOS limitation.

 Your System Locks Up on Initial Boot
 ------------------------------------
 If you cannot access the CMOS setup because your system locks up
 on initial boot, follow the instructions below.

 1. Turn off your system power, check the IDE interface cable and
    power supply cable.

 2. Check jumper settings.

 3. Turn on your system power.

 4. Try to enter your CMOS setup and set the drive type to auto
    config.

 If your system still does not respond, your system BIOS may not
 support drives with more than 4095 cylinders. If this is the case,
 consider these solutions:

 A. Use EZ-Drive.
 If the system locks up and prevents entry to CMOS, you need to
 turn off your system power and disconnect the IDE interface cable
 from the system.

 - Enter your CMOS setup. Refer to your system manual for
   instructions.

 - Select the Hard Disk Type option for the new Western Digital
   hard drive. Select a user defined drive type and enter: 1023
   cylinders, 16 heads, and 63 sectors. If your system does not have a
   user defined drive type, select Type 9.

 - Reconnect your IDE interface cable to the system.

 - Run EZ-Drive or boot to the EZ-Drive 9.06W diskette.These
   new settings allow your system to boot so that you can install
   EZ-BIOS to access the full capacity of the drive.

 - OR -If you do not have a user defined or Type 9 drive type, use
   option B, C, or D below to change the parameters reported to
   the BIOS.

 B. Upgrade your system BIOS
 A properly upgraded system BIOS will support the full capacity of
 your hard drive. Contact your system manufacturer and closely
 follow their specific instructions. See page 3 for a list of common
 system manufacturers and page 12 for BIOS upgrade sources with
 their phone numbers.

 C. Install an EIDE controller card with an onboard BIOS that
 supports hard drives larger than 2.1 GB. For 8.4 GB or larger hard
 drives, the EIDE controller card must support extended BIOS
 functions.

 D. Rejumper the drive as described on the following page and install
 EZ-Drive. With these alternate jumper settings, you MUST install
 EZ-Drive. If you move this hard drive to another system, you
 must put the jumper back to the standard position.
 Note for Windows NT Users: If your system locks up, and you are
 using Windows NT, do not use these alternate jumper settings.
 You need to either use the standard jumper settings on page 2 and
 select a user defined drive type in CMOS setup or upgrade your
 system BIOS to support the full capacity of your new hard drive.

 IMPORTANT
 These alternative jumper settings DO NOT work with Windows NT, Novell
 NetWare, or Unix.

 Single Drive: If you have a 2.5 GB or larger hard drive, your system
 locks up on initial boot, and the drive you are installing is the
 only drive in your system, set the jumpers in these positions.

 Dual (Master) Drive: If you have a 2.5 GB or larger hard drive, your
 system locks up on initial boot, and the drive you are installing is
 the master drive in a twondrive system, set the jumpers in these
 positions.

 CAUTION: Use these jumper settings only if you encounter the
 specific BIOS limitation (system locks up) described in this section.
 These jumper settings cause the drive to report 4092 cylinders
 (2.1 GB) rather than the actual drive capacity. If you use these
 jumper settings, you MUST install EZ-Drive to access the full
 capacity of your new hard drive.


 Dual (Slave) Drive: If you have a 2.5 GB or larger hard drive, your
 system locks up on initial boot, and the drive you are installing is
 the slave drive in a twondrive system, set the jumpers in these
 positions.
