 Jumper Setting
 ==============

 Configuring the drive
 ---------------------
 Required materials:

 - 2-mm jumper connector (supplied as spare jumpers) Your Seagate
   drive is configured using the options jumper block. You can
   configure the drive:

 - For one- or two-drive operation.

 - To be the master or slave drive.

 - To operate as the master with drives that use a different
   master/slave timing protocol.

 - For computers that use cable-select.

 - To use a remote drive-activity LED.

 To configure the drive, attach a jumper to the pins on the options
 jumper block for the desired option.

 The configuration options are:
 Spare jumper
 Spare jumpers are provided on pins 2 and 4 and on pins 6 and 8 for
 configuring your drive. These settings are not used to configure the
 drive. The jumper is a 2-mm connector. If you use a larger connector,
 you may damage the jumper-block pins.

 One-Drive only
 --------------
 Use this configuration if there are no other drives attached to the
 hard disc controller.


 Master with slave present
 -------------------------
 Use this configuration if the drive is the first of two drives in
 your system. The master drive is Drive 0 in the System Setup record.


 Slave
 -----
 Use this configuration if the drive is the second drive in the
 system. The slave is Drive 1 in the System Setup record.


 Master/Slave timing protocol
 ----------------------------
 This protocol involves the communication between the computer and the
 disc drives during the boot cycle only. The computer querues the
 master drive for the status of both drives. The slave must report its
 status to the master within a certain time period. If it does not
 respond, a timeout error is issued and the computer does not identify
 the slave. Place a jumper on pins 3 and 4 and on pins 5 and 6 to
 extend the time period to 30 seconds that the Seagate master waits
 for the slave to respond.


 Cable-Select
 ------------
 Use the configuration if your computer uses cable-select. Refer to
 your computer user's manual.


 Remote LED
 ----------
 Place the ground wire side of the remote drive activity LED
 connector, usually the black wire, on pin 11(-) and the other side on
 pin 12(+) of the options jumper block. The LED may be damaged if the
 cable is attached incorrectly.

   +-----------------+

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


 Mounting the drive
 ------------------
 Required materials:

 - Four 6-32 UNC-2A screws

 The drive fits in a standard 3.5-inch bay and can be mounted in any
 orientation. Position the drive so that the cables are not strained
 or crimped. Secure it with four mounting screws not more than 6 full
 turns (0.20 inches) into the drive frame.

 CAUTION!
 To prevent drive mounting-hole damage, use only the type of screws
 specified.

 This completes the hardware installation.


 Attaching the cables
 --------------------
 Required materials:
 - A four-conductor power-supply cable

 - A 40-conductor interface cable with a 40-pin, female interface
   connector for each drive you want to attach.

 NOTE
 To ensure the integrity of your data, use a nonshielded cable with a
 maximum length of 18 inches (46 cm).

 1. Attach the interface cable. Pin 1 on the drive must align with pin
    1 of the hard-disc controller connector. Use the edge-stripe on
    the cable to denote pin 1. Pin 1 on the drive is located next to
    the four-pin power connector.


 CAUTION!
 The cable and connector bond is delicate. Pulling the cable to remove
 the connector may damage the cable.

 Attach an interface connector to the drive
 If your interface connector has a key, it will plug into the drive
 only one way. Make sure that you do not bend the pins when you attach
 the cable. Attach an interface connector to the hard-disc controller
 connector on the motherboard or host adapter (see your system user's
 guide or host adapter user's guide to determine the location of pin
 1). Make sure that pin 1 is aligned with pin 1 on the drive.


 Cable-select installation:
 -------------------------
 If your computer uses cable-select for connection, refer to its
 user's guide to determine which interface connector is used for the
 master and which is used for the slave.

 2. Attach a power-supply cable to the drive.

 Introduction
 -------------
 The drives in this manual are referred to by their model numbers:
 ST5540A for the Medalist 540sl, ST5851A for the Medalist 851sl,
 ST51080A for the Medalist 1080sl and ST51270A for the Medalist
 1270sl.


 Application
 ------------
 Your Seagate drive is designed for IBM AT and compatible personal
 computers. It uses the ATA interface. It is intended for use with
 UL-listed computers or similar products.


 Drive handling
 --------------
 Do not drop your drive. Do not remove the seals and labels on the
 drive. The drive warranty is voided if the seals and labels are
 removed.


 Static discharge
 ----------------
 Your drive contains components that can be damaged by static
 discharge. Static damage can be cumulative and may not manifest
 immediately.

 Observe these precautions:
 - Ground yourself before handling the drive. Wear a ground strap that
   is properly connected to earth ground, or touch the metal of a
   power supply that is plugged into a wall outlet while handling the
   drive.

 - Keep the drive in its antistatic bag until you are ready to install
   it. Do not attach any cables to the drive while it is in its bag.

 - Handle the drive gently and only by its edges or frame. Place it on
   an antistatic surface until you are ready to install it.

 - Do not touch the drive's connector pins or printed circuit board.


 Warranty
 --------
 Your drive comes with a three-year limited warranty.

 NOTE
 With regards to the EZ-Drive and SEG32BIT.386 software, there are no
 warranties, express or implied, including, but not implied,
 warranties of merchantability or fitness for a particular purpose.
 All such warranties are expressly and specifically disclaimed.
 Maintenance and repair. Seagate drives do not require maintenance.
 The head/disc assembly is sealed; a broken seal voids the warranty.
 Seagate customer service centers are the only facilities authorized
 to repair Seagate drives. Seagate does not sanction any third-party
 repair facilities.

 Warning. Turn off the computer before you remove its cover. Turn off
 the power before you install or remove any adapter card or the drive.


 Transferring the software from the drive
 Required materials:

 - Diskette Drive A

 - A bootable, blank, 1.2-Mbyte or larger diskette for Drive A

 - A bootable diskette with the Format command

 Recent developments in drive technology have pushed drive capacities
 beyond the limits that many older computers using DOS can address.
 Seagate provides software that allows these computers to surpass the
 address limit and access your new drive's full capacity. The software
 is stored on the drive at the factory and must be transferred to a
 diskette in Drive A before you partition and format the drive. The
 files stored on the drive include:

 - EZ-Drive. This is drive installation software that enables
   computers with BIOSs that restrict the hard disc capacity to 528
   Mbytes to surpass the 528-Mbyte barrier.

 - SEG32BIT.386. This is a 32-bit disk access driver to replace the
   native Windows 32-bit disk access driver. It extends 32-bit disk
   access support to drive capacities above 528 Mbytes, multiple block
   read/write and PIO modes 3 and 4.

 - SEAMOVE. This is a program that automatically copies the software
   and README files to a bootable diskette in Drive A. It removes the
   factory installed partition and format when the files are copied.

 - README. This is a text file that contains information about the
   Seamove transfer program.

 To transfer the software, you must put a blank, bootable diskette
 into Drive A. To create a bootable diskette:

 1. Insert your DOS diskette into Drive A.

 2. Type format a: /s. The drive reads the DOS diskette and prompts
    you to insert the diskette you want to format into Drive A.

 3. Insert the blank diskette. Press ENTER. When the format is
    complete, you can transfer the installation software files to the
    diskette.

 To transfer the software files:
 1. Boot the computer with the diskette to which you want to
    transfer the software files.

 2. Enter the System Setup. (Refer to your computer user's guide.
    System Setup may be called Setup, BIOS Setup or CMOS Setup.) If
    your computer uses an automatic setup system, go to step 5.

 3. Find the hard disc configuration in the System Setup screen.

 4. Select drive type 2 for your new Seagate drive. If your computer
    does not offer drive type 2, use the following values: 615
    cylinders, 4 heads and 17 sectors. Note. These are interim
    drivetype values that allow you to access the drive for
    extracting the installation files.

 5. Activate the prompt for the Seagate drive.

 6. Type seamove and press ENTER.
    This command transfers the files from the drive to the diskette in
    Drive A. When the transfer is complete, the Seamove program erases
    the files and the drive partition and reboots the computer. The
    computer returns an invalid drive specification error if you try
    to access the drive.

 CAUTION
 Do not write-protect the Seagate software diskette with EZ-Drive.
 The EZ-Drive program writes important information back to the
 diskette during the installation.


 Configuring the computer
 ------------------------
 Configuring the computer involves updating the computer's System
 Setup records with the new drive's translation geometry (cylinder,
 head and sector information) and partitioning and formatting the
 drive. The translation geometry is kept on the CMOS chip and is used
 by the BIOS to assign locations for the data on the drive. Many older
 BIOSs place limits on the translation geometry parameter values that
 do not allow it to assign data locations for more than 528 Mbytes
 when DOS is used. If your computer uses such a BIOS, it cannot access
 the full capacity of your new drive. This section covers the
 following issues involved with configuring your computer:

 - How to determine whether your computer can access your new drive's
   full capacity

 - Solutions you can use to surpass the 528-Mbyte barrier

 - Installing the drive using the EZ-Drive software

 - Installing the drive using the Standard setup

 - Replacing the Windows 32-bit disk access driver


 Determining whether your BIOS accepts more than 528 Mbytes
 ----------------------------------------------------------
 The following suggestions can help you to determine whether your BIOS
 limits the drive capacity to 528 Mbytes.

 - If you are using a 286 or 386 computer, the native BIOS cannot
   recognize more than 528 Mbytes.

 - If the copyright date of the BIOS is earlier than 1994, the BIOS
   probably will not recognize more than 528 Mbytes. The BIOS
   copyright date, manufacturer and version number appear on your
   screen at the beginning of power-on or rebot.

 - Install the drive using the Standard setup. (Transfer the free
   software stored on the drive to a diskette before you start the
   installation.) When the installation is complete, type DIR D: for
   the new drive, and check the number of bytes free. The number
   should be close to the formatted capacity of your drive. If the
   number is less than 528 Mbytes, you need to consider some
   alternatives for surpassing the 528-Mbyte barrier.


 Solutions for surpassing the 528-Mbyte barrier
 ----------------------------------------------
 - Use the free installation software, EZ-Drive, that is stored on the
   drive at the factory or equivalent software.

 - Upgrade the BIOS to one that supports more than 528 Mbytes. Such
   BIOS incorporate logical block addressing (LBA) and extended
   cylinder-head-sector (CHS) addressing.

 - Use a host adapter that supports more than 528 Mbytes.


 Using the EZ-Drive installation software
 ----------------------------------------
 NOTE
 The EZ-Drive software is authorized for installation only with the
 drive on which it is shipped. EZ-Drive allows your computer to access
 your Seagate drive's full formatted capacity. It bypasses the BIOS
 during the boot sequence and uses information it creates on Drive C
 to identify the drive before DOS is loaded. During the installation,
 EZ-Drive:

 - Determines how many drives are installed

 - Enters a drive type in System Setup for the new drive

 - Modifies the Drive C boot record with translation geometry for the
   new drive

 - Partitions and formats the new drive

 - Copies the boot files to the new drive if it is Drive C

 - Enables Maximum Overdrive, which enables read/write multiple in
   drives that have this feature. The Change Installed Features option
   that appears in the dialog box when the format is complete allows
   you to disable Maximum Overdrive.

 EZ-Drive is easy and safe to use. You can choose the fullyautomatic
 installation, which puts a single partition on the drive, or you can
 install the drive with multiple partitions of equal size and other
 custom features. Online help is available in the Select Installation
 Type menu as Information Help.

 If you already have a drive installed, EZ-Drive will not harm your
 data unless you instruct it to override that drive's partition and
 format. EZ-Drive automatically arranges the drive type position in
 System Setup to reflect how you have set the drive jumpers.

 NOTE
 EZ-Drive is designed for DOS installations. It supports Microsoft
 MS-DOS Version 5.0 or later.

 EZ-Drive does not support:

 - Toshiba laptops, XT or Micro Channel computers

 - Non-ATA hard drives (SCSI, ESDI, MFM and RLL)

 - Some Local Bus adapters that use 32-bit mode

 - Some systems that have PIO mode 3 or 4 active

 - OS/2 and NT

 NOTE
 The Seagate version of EZ-Drive cannot install a NON-Seagate drive
 without a Seagate drive present.

 1. Boot your computer with the Seagate software diskette. This is a
    precaution to ensure that the EZ-Drive installation does not
    conflict with any terminate-and-stay resident (TSR) programs that
    may be in memory.

 2. Type EZ and press ENTER.

 3. Disregard the Notice dialog box. The EZ-Drive software is
    authorized for installation only with the drive on which it is
    shipped. Press ENTER to continue.

 4. Locate the bottom box on the screen. The model number of each
    drive EZ-Drive identifies is listed in this box. If a drive you
    have installed is not listed or the drive order (Drive 0 is the
    master, Drive 1 is the slave) is incorrect or there is a drive not
    identified message, make sure the master and slave jumpers are set
    correctly on the drives and the I/O and power cables are properly
    connected.

 NOTE
 Other troubleshooting tips are available in the Information Help
 menu.

 5. If the drives are correctly identified, select Select Fully
    Automatic Installation in the Select Installation Type dialog
    box. This creates a single partition and formats the drive. If you
    are installing the drive as Drive C, EZ-Drive automatically
    writes the system files to the drive to make it bootable.

 6. When the format is complete, the Options dialog box appears.
    Select and read Important Information. This instruction tells you
    how retain the use of the EZ-Drive-installed drive when you boot
    to Drive A.

 7. Select Reboot to reboot the computer and save the installation.


 Partitioning and Formatting the drive
 -------------------------------------
 Before you can use your Seagate drive, you must partition and format
 it. In this guide we discuss partitioning and formatting your drive
 with DOS_refer to your DOS user's guide for assistance. If you are
 using another operating system, consult your operating system user's
 guide for partitioning and formatting instructions. Note. If you have
 not copied the free installation software to a diskette, your
 computer will detect a partition on the drive. You must erase this
 partition before you can access the full drive capacity. When you
 transfer the files to a diskette using SEAMOVE, the partition is
 automatically erased when the transfer is complete.


 Low-level formatting
 --------------------
 The drive is low-level formatted at the factory using 512 bytes per
 sector. Low-level formatting is not required.


 Partitioning
 ------------
 You must partition the drive into one or more logical drives before
 you can use it.

 CAUTION
 Partitioning or formatting a drive at any level erases all data on
 it. Make a backup copy of your existing files on another drive before
 you repartition or reformat. Seagate assumes no liability if you
 erase your data.


 High-level formatting
 ---------------------
 High-level formatting (henceforth referred to as formatting) builds
 the file allocation table (FAT) DOS uses to access files on the
 drive. If you put more than one partition on the drive, you must
 format each partition. Use the DOS FORMAT utility to format the
 drive.
