 The CP2088 drive is designed to operate either as a master drive (C
 Drive) or a slave drive (D Drive). This feature is dependent on two
 drive settings; the status of hardware Jumper E1 and the firmware
 setting of a feature bit. When (E1) is closed, and the feature bit is
 set, the drive will assume the role of a Master Drive. When (E1) is
 open, and the feature bit reset, the drive will act as the Slave. In
 single drive configurations E1 must remain in the closed position.


 Get drive Feature byte (00)
 ---------------------------
 This command fetches the drive feature bytes and returns it in the
 Cylinder High and Cylinder Low Registers. The bit meaning is as
 follows:

   bit 15  RESERVED
   bit 14  RESERVED
   bit 13  RESERVED
   bit 12  RESERVED
   bit 11  RESERVED
   bit 10  RESERVED
   bit 9   RESERVED
   bit 8   Selection of non-Conner master/slave
   bit 7   RESERVED
   bit 6   RESERVED
   bit 5   Special reset mode
   bit 4   Enable Master/Slave
   bit 3   Disable look ahead reads
   bit 2   RESERVED
   bit 1   RESERVED
   bit 0   0 to enable the Power commands

 It is important to read the Feature byte and the only change the bits
 of interest leaving the outer bits unaffected.


 Set drive Feature byte (01)
 ---------------------------
 This command uses the Cylinder High and Cylinder Low Registers to set
 the feature byte in the EEPROM of the drive. See the above table for
 bit meaning.

 The drive may be mounted in any attitude!


 Recommended Mounting Configuration
 ----------------------------------
 This CP2088 is designed to be used in applications where the unit
 may experience shock and vibrations at greater levels than larger
 and heavier disk drives.

 The design features which allow greater shock tolerance are the use
 of rugged heads and media, a dedicated landing zone, closed loop
 servo positioning and specially designed motor and actuator
 assemblies.

 Four (4) side mounting points and four (4) bottom mounting points are
 provided to the customer. The drive is mounted using 3mm x 0.5mm
 thread screw. The screw insertion depth should not exceed 4mm into
 the mounting holes. The system integrator should allow ventilation
 to the drive to ensure reliable drive operation over the operating
 temperature range.

 For additional vibration isolation, an external suspension system
 may be used.


 Interface Connector
 -------------------
 The CP2088 drive has a 44 pin right angle interface/power connector
 mounted on the PCB. The recommended mating connector is DuPont part
 number 69764-044 or equivalent. The maximum cable lenght is two
 feet.


 Diagnostic Routines
 -------------------
 The microprocessor performs diagnostics upon application of power.
 If an error is detected the drive will not come ready.


 Magnetic Field
 --------------
 The externally induced magnetic flux density may not exceed 6 gauss
 (DC - 700KHz) or 1.0 gauss (700KHz - 1.5MHz) as measured at the
 drive surface.


 Acoustic Sound Emission
 -----------------------
 Pressure: The sound pressure level for the operating drive will not
 exceed 34 dB(A) max. at a distance of 1 meter from the drive.

 Seek Times
 ----------

       +----------------------------------+--------+
       |Physical track to track      max. |   5 ms |
       |Logical                      max. |  10 ms |
       +----------------------------------+--------+
       |               Average msec. typ. |  19    |
       |               Average msec. max. |  40    |
       +----------------------------------+--------+
       |Latency                msec. avg. |   8.6  |
       +----------------------------------+--------+
       The timing is measured through the interface with the drive
       operating at nominal DC input voltages. The timing also assumes
       that:
             - BIOS and PC system hardware dependency have been
               subtracted from timing measurements.

             - The drive is operated using its translation parameters.


       The average seek time is determined by averaging the seek time
       for a minimum of 1000 seeks of random length over the surface
       of the disk.


 Functional Description
 ----------------------
 The CP2088 contains all necessary mechanical and electronic parts to
 interpret control signals, position the recording heads over the
 desired track, read and write data, and provide a contaminant free
 environment for the heads and disks.


 Read/Write and Control Electronics
 ----------------------------------
 One integrated circuit is mounted within the sealed enclosure in
 close proximity to the read/write heads. Its function is to provide
 head selection, read preamplification, and write drive circuitry.

 The microprocessor-controlled circuit card provides the remaining
 electronic functions which include:

        - Read/Write Circuitry
        - Rotary Actuator Control
        - Interface Control
        - Spin Speed Control
        - Dynamic Braking
        - Power Management

 A microprocessor performs diagnostics upon application of power. If
 an error is detected the drive will not come READY. At power down or
 the start of STANDBY MODE or SLEP MODE the heads are automatically
 retracted to the inner diameter of the disk and are latched and
 parked on a landing zone that is inside the data tracks.


 Drive Mechanism
 ---------------
 A brushless DC direct drive motor rotates the spindle at 3486 RPM.
 The motor/spindle assembly is dynamically balanced to provide minimal
 mechanical run-out to the disks and to reduce vibration of the HDA. A
 dynamic brake is used to provide a fast stop to the spindle motor
 and return the heads to the landing zone inside the data tracks
 when power is removed or upon initiation of STANDBY MODE.


 Air Filtration System
 ---------------------
 Within the sealed enclosure, a 0.3 micron filter which provides a
 clean environment for the heads and disks.


 Head Positioning Mechanism
 --------------------------
 The read/write heads for the CP2088 is supported by a mechanism
 coupled to the voice coil actuator.


 Read/Write Heads and Disks
 --------------------------
 Data is recorded on 65mm diameter thin film disk through micro-
 miniature THIN FILM or MIG heads.

 The drive is designed to be used in applications where the unit may
 experience shock and vibrations at greater levels than larger and
 heavier disk drives.


 Universal Translate Mode
 ------------------------
 Conner has established a Universal Translate Mode which enables the
 user to configure the drive in an AT environment to any cylinder,
 head, and sector configuration desired. The translate configuration
 is limited only by the maximum capacity of the drive. Upon initial
 power up to the drive it will default to a predetermined configura-
 tion shown below:

          Cylinders        Heads       Sectors
 CP-2088     548             8           38


 Error Correction
 ----------------
 The CP2088 drive use a Reed-Solomon code to perform error detection
 and correction. The error correction polynominal is capable of
 correcting one error burst with a maximum of 22 bits or 2 error
 bursts of up to 11 bits each, per 512 byte block. Single bursts of
 11 bits or less are corrected with no performance degradation.


 Execute Drive Diagnostic
 ------------------------
 Command Number: 90 hex

 Description
 This command performs the internal diagnostic tests implemented by
 the drive. The diagnostic tests are only executed upon receipt of
 this command.

 The drive sets BSY immediately upon of the command. If the drive is a
 master, the drive performs the diagnostic tests and saves the
 results. It then checks to see if a slave drive is present and waits
 up to 5 seconds for the slave to complete its diagnostics. If the
 slave successfully completes its diagostics, it asserts -HOST PDIAG.
 If unsuccessful, the master drive resets BSY in the Status register
 and generates an interrupt.

 The value in the Error register should be viewed as a unique 8-bit
 code and not as the single-bit flags defined previously. The inter-
 face registers are set to initial values except for the Error
 register.

 The table below details the codes in the Error register and a
 corresponding explanation.

 Error Code    Description
 01 hex        No error detected
 02 hex        Format device error
 03 hex        Sector buffer error
 8x hex        Slave drive failed

 Additional codes may be implemented at the manufacturer's option.

 NOTE
 If the slave drive fails diagnostics, the master drive shall "OR" 80
 hex with its own status and load that code into the Error register.
 If the slave drive passes diaagnostics or there is no slave drive
 connected, the master drive shall sect bit 7 of the Error register
 Task File to 0.
