 Mounting Orientation
 --------------------
 The disk drive shall operate within specified error rates in all axis
 with no limitation. The test was done within  5 degrees from these
 positions.

 Performance and error rate must stay within specification limits if
 the disk drive is operated in the other permissible orientations from
 which it was formatted. Thus a disk drive formatted in a horizontal
 orientation must be able to run vertically and vice versa.


 Cabling
 -------
 The maximum cable length from the host system to the HDD plus circuit
 pattern length in the host system shall not exceed 18 inches.


 Identification
 --------------
 The following labels are affixed to every disk drive.

 1. A label placed on the top of the HDA containing the statement
    "Made by IBM" or equivalent, Part No., EC No. and FRU No.

 2. A bar code label can be placed on the disk drive based on user
    requirements. The location on the disk drive will be designated by
    Low End Storage.

 3. Labels containing the vendor's name, disk drive model number,
    serial number, place of manufacturing and UL/CSA logos.

 Except for the bar code, labels may be integrated with Low End
 Storage designed label.


 Air Cooling requirement
 -----------------------
 The system is responsible to provide sufficient air movement to main-
 tain file temperature 60*C at the center of TOP COVER of file.


 Interface Logic Signal Levels
 -----------------------------
 The interface logic signal have the following electrical
 specifications:

 Inputs:  Input High Voltage    -   2.3 V min.
          Input Low Voltage     -   0.8 V max.

 Outputs: Output High Voltage   -   3.0 V min.
          Output Low Voltage    -   0.5 V max.



 Addressing of HDD Registers
 ---------------------------
 The host addresses the drive through a set of registers called the
 Task File. These registers are mapped into the host's I/O space. Two
 chip select lines (-HCS0 and HCS1) and three address lines (ADDR 0-2)
 are used to select one of these registers, while a -IOR or -IOW is
 provided at the specified time.

 The HCS0 is used to address Command Block registers, while the HCS1
 is used to address Control Block registers.


 Connectors
 ----------
 The DC power connector is designed to mate with AMP part 1-480424-0
 using AMP pins part 350078-4 (strip) or part 61173-4 (loose piece),
 or their equivalent.

IBM       AT INSTALLATION (IDE-AT1)

 IDE Installation Guide Generic

 Installation requirements
 -------------------------
 To install an IDE drive inside your computer, you must have:

 1 The documentation that came with your computer.

 2 The documentation that came with your hard drive.

 3 A small, flat blade screwdriver.

 WARNING: Do not open the static-protective bag containing the drive
 until instructed to do so. Static electricity can damage the drive.


 Preparing the drive for installation
 ------------------------------------
 Master drive If this drive is the first or primary hard disk drive to
 be installed inside your computer, check the manual that came with
 your hard drive to locate the Master setting. If your drive is set to
 a Master, do not change the jumper position.

 Slave drive If this drive is the second or secondary hard disk drive
 in your computer, you must change the jumper position on the drive to
 Slave. Refer to the manual that came with your hard disk drive to
 locate the Slave setting.

 To change the jumper on the hard disk drive:

 1 Remove the drive from the static-protective bag and place it on top
   of the bag.

 2 Refer to your manual and locate the pins.

 3 If you need to change the setting, grasp the jumper and pull it off
   the pins.

 4 Line up the two holes in the bottom of the jumper with the
   approprate two pins on the drive. Push the jumper onto the pins
   until the jumper is completely seated and covers both pins.


 Installing the drive
 --------------------
 For the specific information on installing a hard disk drive, refer
 to the documentation that came with your computer. You will be
 required to mount the drive inside your computer, connect signal and
 power cables to the hard drive, and update the configuration
 information.


 Handling precautions
 --------------------
 01 Turn off all attached devices first; then turn off the computer.

 02 Unplug all the power cords from electrical outlets before starting
    installation.

 03 Disconnect all power cables from your computer and attached
    devices before starting installation.

 04 Limit your movement. Movement can cause static electricity to
    build up around you.

 05 Handle the drive carefully and by the edges.

 06 Do not touch any exposed printed circuitry.

 07 Prevent other people from touching the components or the drive.

 08 When you are installing the drive, touch the static-protective
    package containing the drive to a metal expansion-slot screw or
    other unpainted metal surface on the computer, for at least 2
    seconds. (This drains static electricity from the package and your
    body.)
 09 When possible, remove the drive and install it directly into the
    computer without setting it down. If this is not possible, place
    the drive, component side up, on the static-protective bag on a
    flat surface until the drive is installed.
 10 Do not place the drive on the computer cover or on a metal table.

 Note: Be sure to use the correct screws provided with your drive.
 Using the wrong ones might cause damage to the drive.


 Completing the installation procedure
 -------------------------------------
 The installation of the drive is complete. Reinstall the cover on the
 computer or storage enclosure. Store these instructions and any extra
 parts in a safe place in case you change your configuration.
 After installing your hard disk drive, use the information that came
 with your computer to reconfigure your system. When you power on your
 system, turn on all attached devices first; then turn on the
 computer.

 If you have any problems at this point, turn off all attached
 devices; then, turn off the computer and check that:

 1 The cables are installed correctly

 2 No options or cables are loose

 3 The jumpers are properly set Turn on all attached devices; then,
   turn on the computer. If you still have a problem, refer to the
   troubleshooting information in the documentation that came with
   your computer.


 Update configuration
 --------------------
 Whenever you add or remove an option from your computer, you must
 update the configuration information. Your computer might have an
 automatic configuration program, or you might have to follow a
 specific procedure. For more information, refer to the documentation
 that came with your computer.


 Preparing the drive for use
 ---------------------------
 Having successfully installed the hard disk drive, you need to
 prepare it for use. Depending on the operating system you are using,
 you might need to partition then format the hard disk. Refer to the
 documentation that came with your operating system for information on
 how to format your new drive.
 To make the drive just installed your primary drive, you might need
 to create a new system partition on the drive. For information on
 creating a new system partition, refer to the documentation that came
 with your operating system.


 Troubleshooting
 ---------------
 You might be able to solve a problem yourself. Before calling IBM,
 you might want to try some or all of the following troubleshooting
 procedures.

 1 Remove and reattach all drive cables

 2 Remove and reseat the drive

 3 Place the drive in a different slot, if one is available

 4 If your drive contains jumpers or switches, check that they are set
   as specified

 5 Reread any software instructions; be sure software settings are
   correct

 6 Inspect the drive for damage, such as bent pins

 7 Check the computer manual for instructions about the installation
   of upgrades. Look for a section about system setup or system
   configuration. Follow all procedures.

 8 After completing these steps, reassemble the computer and connect
   the power cord

 If you are still having problems and want to call IBM technical
 support, have available as much of the following information as
 possible:

 1 Drive model or P/N and description

 2 Computer manufacturer and model

 3 Exact wording of error message (if any)

 4 Description of the problem

 5 Hardware and software configuration information for your system

 If possible, be at your computer. Your technical support rep might
 want to walk you through the problem during the call.
