Cable Select Option
The drive can be configured so the status of a master or slave can be
determined by the cabling from the host system. The drive can
recognize it self as either Drive 0 or Drive 1.

The drive is configured as either a master (drive 0) or a slave
(drive 1) depending on the value of the CSEL signal (pin 28). If CSEL
is grounded, then the drive address - 0. If CSEL is open, then the
drive address - 1.

Special cabling is required from the system manfacturer to selectivly
ground or open the CSEL signal.

 1. Install a 40 pin Data Cable ensuring that pin 1, which can be
    identified by the striped edge of the cable, is closest to the
    power connector on the drive.

2. Install a DC power cable to the back of the drive.

 3. Verify the jumper configurations for Master/Slave operation
    (Note:  Master will be the bootable drive. The slave will not
    be bootable.) Also make sure the existing C: drive is jumped
    to be the Master in a two drive system, not the only drive in
    the system.

4. Apply power to the computer.

 4a. When memory test is complete go into your system's Standard
     CMOS set-up.
     (Note: There are various ways to get into CMOS set-up, please
     refer to system's manual for instructions.)

 4b. If your system's BIOS supports a user programmable drive
     type, program the BIOS with the default parameters of your
     drive. If your system does not support a user programmable
     drive type choose parameters that closely match but do not
     exceed the drives MegaByte capacity. Escape from set-up
     then choose write to CMOS and exit.

 5. Boot from a DOS diskette that has FDISK.EXE and FORMAT.COM on
    it. At the A> prompt type in FDISK. At the menu options select
    option 1 to create a DOS partition. Another menu will appear
    and from those options choose 1 to create a Primary DOS
    partition. Select yes to make 1 large partition and it will
    automatically become active. Then escape from FDISK.

 6. At the A> prompt type in FORMAT C:/S This does a high-level
    format on the drive and transfers the system files in order for
    the drive to be bootable. (Note: IDE drives are low-level
    formatted from the manufacturer and only need a high-level

    To configure the drive as a slave drive repeat steps 1-4 and
    proceed with steps 5a. and 6a. as follows:

  5a. At the C> prompt type in FDISK. When the menu options appear
      select option 5 to switch to the second drive. Enter fixed
      disk drive number 2. Then choose option 1 to create a DOS
      partition, then select option 1 again to create a Primary DOS
      partition or option 2 to create an Extended DOS partition.
      (Note: C and D drives will always be the Primary partitions
      but only the Primary partition on C: will have a status of

  6a. Proceed with a high-level format on the drive by typing FORMAT
      D: (Note: Make sure the correct drive letter has been selected
      for format).

 7. The drive is now bootable. As a test remove the DOS diskette
    from A and press reset to reboot the computer,  a  C> should be
    displayed, the drive is now ready for operation.
