BASIC INSTALLATION STEPS

- Drive is shipped with an ID of 6 to provide spare jumpers.
  Choose address jumpers according to specific installation requirments.

- The last physical device on the SCSI bus must be terminated.
  Any other SCSI device connected between the host and the device at
  the end of the bus must NOT be terminated.

- Install a 50-pin ribbon connector. The striped edge of the 50-pin ribbon 
  cable represents pin 1 and must be oriented towards pin 1 at the drive 
  connector and the host connector.

- Install the DC power connector.

- Secure the drive in a bay with 6-32 x 1/4" screws.

- Set the drive type in the AT BIOS setup to "not installed". 
  Note: This intelligent drive will identify itself to the system and 
  SCSI host adaptor.

- The drive is now ready for partitioning and high-level formatting
  with any operating system. For example:

    Partition the drive using the FDISK program from MS-DOS 
    version 3.3 or higher.

    High-level format the drive using the FORMAT command from 
    MS-DOS version 3.3 or higher.
