Installation of the Drive and Adapter Card
1. Remove power to the computer

  2. If another hard disk controller is installed, it is necessary to
     prevent it from responding to the addresses 1F0-7H and 3F6-7H.
     It is also necessary to ensure that the controller is
     electrically disconnected or tri-stated from IRQ14 of the mother-
     board bus. This may be done either by removing the board, by
     electrically disconnecting the signal from the interface, or by
     setting the jumpers of the board to select the alternate address
     for the hard disk.

3. Insert the board into any available card slot.

  4. Configure the Host adapter for the correct configuration of your
     computer BIOS.

     Adapter Card Jumpers   E1 and E3 always not installed
                            E2 and E4 always installed

     Note: E3 and E4 are located in a straight line with a pin between
           them, as shown below. Jumper in refers to the pin jumpered
           to the center pin.

                         o  o  o

5. Connect power to the Disk Drive.

  6. Run the DOS FDISK program (or equivalent) to establish DOS

     Note: DOS 3.2 and below have limitations of 32 megabytes unless
           software utility is used to overcome this.

  7. Run the DOS format program by typing "Format C:/S". The volume
     may be named with the addition of the "/V". The format will be
     completed and the system transferred if the "/S" option was used.
     The system will ask for a volume name if the "/V" option is used.

8. Files can then be copied to the C: drive from the floppy.

  9. When the system is rebooted, the system should boot from the hard
     drive (Drive C:) if the floppy is removed.

Installation direction
The drive may be mounted in any attitude!

Recommended Mounting Configuration
This drive is designed to be used in applications where the units 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

Ten base mounting points are provided to the customer. The drive is
mounted using 6-32 x 1/8" max. insertion for the sides, and 0.20"
insertion for the bottom. 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.

Power Connector
The drives have a 4 pin DC power connector (J4) mounted on the PCB.
The recommended mating connector is AMP part number 1-480424-0
utilizing AMP pins, part number 350078-4 or equivalent. DC power may
also be supplied to the drive in some interfaces through a 3 pin
connector is Molex part number 39-01-0033 utilizing Molex pins, part
number 39-00-0031 or equivalent.

Task File Interface Connector
A 40 pin Task File Interface connector mounted on the printed circuit
board. The recommended mating connector is Molex part number 10-91-
2401 or equivalent. Two drives may be daisy chained together at this
connector, and the maximum cable lenght is two feet.

 Magnetic Field
 The disk drive will meet its specified performance while operating in
 the presense of an externally produced magnetic field under the
 following conditions.
   |Frequency         |   Field Intensity|
   |   0 to 700 Khz   |   6 gauss maximum|
   | 700Khz to 1.5Mhz |   1 gauss maximum|

Acoustic Noise
The sound pressure level will not exceed 40 dBA at a distance of 1
meter from the drive.



Key Features
The CP30104H is a high performance 3.5 inch low-profile (1") 121
megabyte (formatted) disk drives with 19 ms average seek time, that
is designed to operate on an IBM PC/AT or equivalent in translate
mode. The CP30064H is a 60 megabytes (formatted) versions of the
drive. The drives feature low power requirements and high shock
resistance, enabling battery operation in portable environments.

Because the drive contains the Task File within its control logic, it
requires a simplified adapter board to operate. Conner Peripherals
has developed an adapter board to be used in conjunction with the
drive on an AT or equivalent system.

 - Low power requirements enabling battery operation in portable

 - High performance rotary voice coil actuator with embedded servo

- One of seven run length limited code.

- High shock resistance

- Sealed HDA

- Automatic actuator latch against inner stop upon power-down.

 - Microprocessor-controlled diagnostics routines that are auto-
   matically executed at start-up.

- Automatic error correction and retries

- 512 bytes block size

- Emulates Task File with support additional commands.

- Up to two drives may be daisy-chained on the AT interface.

- 32K Look Ahead buffer

Split ECC
The new generation of Conner drives feature a split sector, that is a
512 byte sector split into two segments. This allows improved error
correction performance. The first 254 bytes of the sector are written
with their own ECC syndrome which allows for a corrections of any
single defect of up to 8 consecutive bits. The second 267 bytes of a
sector also have their own ECC syndrome which allows an additional
defect correction in the second half of the sector. This allows for
1 ECC correction for each half of a sector or up to two for each
sector depending on placement.

Some diagnostics expect an uncorrectable error to be reported when
there are two defects more than 8 bits apart. This will not happen if
the defects are in different segments off the sector, and in that
case the improved correction capability will correct both errors. On
a read long, the drive returns 512 bytes of data plus 7 bytes of ECC.

Seek Times

       |Track-to-Track         msec.      |   8    |
       |               Average msec. typ. |  < 19  |
       |               Average msec. max. |  35    |
       |Latency                msec. avg. |   8.8  |
       The timing is measured through the interface with the drive
       operating at nominal DC input voltages. The timing also assumes
             - BIOS and PC system hardware dependency have been
               subtracted from timing measurements.

             - The drive is operated using its translation drive

       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.

Write Precomp Register
(-HOST CS0, address 1 write only) A register previously used to set
write precompensation, that is present but is used only for enabling
or disabling LOOK AHEAD READ's.

Functional Description
The drive 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 pre-amplification, and write drive circuitry.
The read/write heads are supported by a mechanism coupled to the
voice coil actuator.

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

        - Read/Write Circuitry

        - Rotary Actuator Control

        - Interface Control

        - Spin Speed Control

        - Dynamic Braking

        - Power Management

At power down or the start of STANDBY MODE the heads are automatic-
ally retracted to the inner diameter of the disk and are latched and
parked on a landing zone that is off the data tracks.

Drive Mechanism
A brushless DC direct drive motor rotates the spindle. The motor/
spindle assembly is balanced to provide minimal mechanical runout 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 when power is
removed, or upon initiation of STANDBY MODE.

Air Filtration System
The head-disk assembly is a sealed enclosure with an integral 0.3
micron filter which maintains a clean environment for the heads and

Head Positioning Mechanism
The four read/write heads are supported by a mechanism coupled to the
voice coil actuator in the CP30104H. Two heads are removed and a
counter balancing weight is substituted in the CP30064H.

Read/Write Heads and Disks
Data is recorded on 95mm diameter disk through four miniature metal-
in-gap heads. The configuration is one disk and two heads for the

Error Correction
The drive performs internal error correction. The error correction
polynominal is capable of correcting one error burst with a maximum
of 8 bits in each half of a 512 byte block.

 Reliability and Maintenance
 MTBF                    100,000 hours (base on field return data

Peripherals shall not be liable for errors contained herein or for
incidental consequential damages in connection with the furnishing,
performance, or use of this material.

If at power on, the drives spins up but is ignored by the system
(indicated by the system taking a long time to boot) it is possible
the IRQ14 is not becoming active. Check to make sure that the
interrupt is isolated electrically from the original hard disk
controller's IRQ13.

If at power on, the drive does not spin up right away or does not
spin up until after the computer completes power on, it is possible
that RESET is either continually active or is electrically
connected to some other signal.

If when taking a directory it is inacccurate or does not change, it
is possible that the adapter board is connected to bit 7 when address
3F7 is read.

If the computer completes its power on sequence before the drive is
up completely and subsequently gets a 17xx error of some sort, and if
a subsequent warm boot is sucessful, it is possible the BIOS is
expecting a different status at power on before the system is ready.
Either delay the power on sequence or change the BIOS to expect a 00
status before the drive becomes ready.

Additionally, if the drive does not function as indicated, combina-
tions of jumpers E2, E3 and E4 can be made to determine the correct
configuration. An explanation of the jumpers follows:

   Jumper E2 enables or disables chip select 1 (CS1). Installed
   enables it.

   Jumper E3 will clear IRQ14 with deassertion of Host SLV/ACT.

   Jumper E4 will clear IRQ14 with a status read only.

Care must be exercised with the routing of the power & signal cables.
They should not be routed next to the drive PCB or other high
frequency or large current switching signals. Improper drive
operating can result from improper cable routing.
