 NOTES
 1. Jumpers for JP1, 2, and 3 should not be selected concurrently.

 2. JP1 is for Master, JP2 is for Slave, JP3 is for Cable Selection
    mode.

 3. To enable Cable Selection mode, the JP3 jumper must be installed.
    In the Cable Selection mode, the drive address is determined as
    follows:

       - When CSEL signal (pin 28) is grounded or at a low level, the
         drive address is 0 (master).

       - When CSEL signal is open or at high level, the drive address
         is 1 (slave).

 4. Position JP4 is reserved.

 5. When JP5 is installed, write cache function is disabled.

 6. When JP6 is installed, auto reallocation and write cache functions
    are disabled.

 7. When JP7 is installed, the capacity is set to 541MB. Otherwise,
    the capacity is set to 528MB.

 Drive Mounting
 --------------
 The drive will operate in all axes (6 directions). Performance and
 error rate stay within specification limits even if the drive is
 operated in other orientations from which it was formatted.

 For reliable operation, it is recommended to mount the drive in a
 system securely enough to prevent excessive motion or vibration of
 the drive during seek operation or spindle rotation by using
 appropriate screws or equivalent mounting instruments.
 Drive level vibration test and the shock test are to be conducted
 with the drive attached to the table by using four bottom screws
 (6-32 UNC).

 Recommended screw torque to be applied to mounting screws is 0.6 -
 1.0 Nm (6 - 10 kg*cm).


 Identification Labels
 ---------------------
 The following labels are affixed to every hard disk drive shipped
 from the manufacturing location in accordance with appropriate hard
 disk drive assembly drawing.

  - A label contaning the IBM logo, IBM part number and the statement
    "Made by IBM Japan Ltd.".

  - A label containing the drive model number, date code, formatted
    capacity, place of manufacture, and UL/CSA/TUV logos.

  - A bar code label containing the drive serial number.

  - An user designed label per agreement.

 The labels may be integrated with the other labels.


 Cabling
 -------
 The maximum cable length from the host system to the HDD, plus the
 circuit pattern length in the host system, cannot exceed 45.7 cm.


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

  Inputs:  Input High Voltage    2.0 V min.
           Input Low Voltage     0.8 V max.

  Outputs: Output High Voltage   2.4 V min.
           Output Low Voltage    0.5 V max.


 There is a choice of 2 power connections to this drive. One DC power
 connector is designed to mate with AMP part 1-480424-0 (using AMP
 pins P/N 350078-4) strip or (part 61173-4) loose piece, or their
 equivalents. The other (3 pin) DC power connector is designed
 to mate with MOLEX 5480-03 (using MOLEX pins 5479). Equivalent
 connectors may be used. Pin assignments are shown below.

   +-----+         +-------+
   |3 2 1|         |4 3 2 1|
   +-----+         +-------+
    | | +- +5V      | | | +-- +12V
    | +--- +12V     | | +---- GND
    +----- GND      | +------ GND
                    +-------- +5V


 AT Signal Connector
 -------------------
 The AT signal connector i sa 40-pin connector.
 The drive uses single-ended drivers and receivers. The connector is
 designed to mate with 3M part 3417-7000 or equivalent.

 Note: It is intended that the hard disk drive should only be in
 electrical contact with the chassis of the PC at a designated set of
 mounting holes. Other electrical contact may degrade error rate
 performance. As a result of this, it is recommended that there should
 be no metal contact to the hard disk drive except at the mounting
 holes or the side rails into which the mounting holes are tapped.


 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 (HA 00-02)
 are used to select one of these registers, while a -HIOR or -HIOW 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.

 Error Register
 --------------
   +-----------------------------------+
   |       Error Register              |

   |BBK|UNC| 0 |IDNF|0 |ABRT|TK0NF|AMNF|
   +---+---+---+----+--+----+-----+----+

 This register contains status from the last command executed by the
 drive, or a diagnostic code.

 At the completion of any command except Execute Drive Diagnostics,
 the contents of this register are valid always even if ERR = 0 in the
 status register.

 Following a power on, a reset, or completion of an Execute Drive
 Diagnostic command, this register contains a diagnostic code.

 Bit Definitions
 BBK       Bad Block. BBK = 1 indicates a bad block mark was detected
           in the requested sector's ID field.

 UNC       Uncorrectable Data Error. UNC = 1 indicates an
           uncorrectable data error has been encountered.

 IDNF(IDN) ID Not Found. IDN = 1 indicates the requested sector's ID
           field could not be found.

 ABRT(ABT) Aborted Command. ABT = 1 indicates the requested command
           has been aupported to a drive status error or an invalid
           parameter in an output register.

 TK0NF     Track 0 Not Found. T0N = 1 indicates track 0 was not found
 (T0N)     during a Recalibrate command.

 AMNF(AMN) Address Mark Not Found. AMN = 1 indicates the data address
           mark has not been found after finding the correct ID field
           for the requested sector.


 Cable Noise Interference
 ------------------------
 To avoid any degradation of performance throughput or error rate when
 the interface cable is routed on top or comes in contact with the HDA
 assembly, the drive must be grounded electrically to the system frame
 by four screws. The common mode noise or voltage level difference
 between the system frame and power cable ground or AT interface cable
 ground should b ein the allowable level specified in the power
 requirement section.


 Unit Sound Power Level Testing
 ------------------------------
 Sound power emission levels are measured according to ISO 7779.


 Shipping Zone and Lock
 ----------------------
 A dedicated "shipping" (or "landing") zone on the disk, not on the
 data area of the disk, is provided to protect the disk data during
 shipping, movement, or storage. At power down, the heads are auto-
 matically parked and a head locking mechanism secures the heads in
 this zone.


 Buffering Operation (Look-ahead/Write cache)
 --------------------------------------------
 In order to improve the total performance, the drive utilizes its own
 buffer for lookahead. The total of 96KB of the buffer is divided into
 three segmented blocks. Those three segments are managed
 intelligently to obtain the best performance.

 APPLICATION NOTE: Deskstar DALA-3540 drives and ATAPI CD-ROM drives
 -------------------------------------------------------------------
 We are aware of reports of problems with applications of Deskstar
 drives with ATAPI CD-ROM drives, where the CD-ROM cannot be detected
 by its driver at boot time. These problems are occurring because of
 non-compliances in the ATA implementation by the CD-ROM
 manufacturers.

 Our laboratories have investigated several CD-ROM drives, and have
 determined that several ATAPI suppliers have not complied in their
 timing of the -DASP line, used for slave drive detection after a
 reset. Incorrect timing of -DASP can cause the Deskstar DALA-3540
 drive, as a master, to fail to recognise the presence of the slave.

 The incompatibility being discussed only occurs when the hard drive
 and the CD-ROM are sharing one bus. Dual bus Enhanced-IDE systems
 where the hard drive and ATAPI CD-ROM are on separate buses are not
 affected.


 ATAPI implementation
 --------------------
 The ATAPI implementation of a CD-ROM interface has only emerged
 into the marketplace in the last 6 months. There are several
 recognised problems associated with the total compliance of these
 drives with the ATA specification, which are still being addressed by
 changes, and the implementation cannot be regarded as stable.


 DASP timing
 -----------
 The ATA spec defines -DASP (device active, slave present) as a
 time multiplexed signal which indicates that a device is active,
 or that a slave is present. The signal has an open collector output,
 and each device has a 10K ohm pull-up resistor. During power on
 initialisation, or after -RESET has been negated, the -DASP will be
 deasserted by both devices within 1ms, then the slave will assert
 -DASP within 400ms to show that it is present. The master is expected
 to allow up to 450 ms for the slave to assert -DASP.

 The non-compliant ATAPI CD-ROM drives are asserting -DASP, but are
 deasserting it within 450 ms of -RESET being negated, where this
 should have been held until either a command was accepted, or 31
 seconds had elapsed.

 The Deskstar DALA-3540 drive was designed to check -DASP at 450ms,
 which is compliant with the ATA specification, but at that time, the
 non-compliant CD-ROM drives had deasserted -DASP, and were not
 visible to be recognised as slaves.
