  DCAACHG.EXE: 'SET MAXIMUM CAPACITY' utility for DCAA-34330 Drive	
  ================================================================

  The DCAACHG.EXE utility provides the means to change the capacity 
  of the DCAA-34330 drive by modifying the number of 'logical'
  cylinders on the drive.

  The utility runs under DOS so a DOS bootable diskette will be required to
  boot the system before the utility can be executed.
    	
  The following changes to drive total cylinders are possible:	

  1) 8126 cylinders (CHS = 8126,16,63)
  2) 8192 cylinders (CHS = 8192,16,63)
  3) 8400 cylinders (CHS = 8400,16,63) - Ship default setting.

    To execute the utility proceed as follows:

  1) Boot the system from the DOS bootable diskette. 

  2) Insert the diskette containing the DCAACHG.EXE utility.	

  3) At the A:\ command prompt type DCAACHG & press the ENTER
     key.
     A menu will appear prompting you to select a drive capacity	
     by pressing the appropriate function key:

     F1: Help Screen
     F3: Set to 4.22GB  (8192 cylinders)
     F4: Set to 4.19GB (8126 cylinders)
     F5: Set to 4.33GB  (8400 cylinders)

  4) Press the required function key.
     A window will appear and the utility will detect all DCAA-34330 drives 
     attached to the Primary and Secondary IDE ports. This may take upto a
     minute to complete.

  5) Once the detection is complete, DCAA-34330 drives will be highlighted.
     Using cursor keys and the Y/N keys select drives for capacity setting
     by placing a 'Y' in the selection column.

  6) Press the ENTER key when all selections are made.
     Follow the onscreen prompts to confirm your selection by pressing 
     the ENTER key, or quit by pressing a Function key.

  7) The drive capacity will be changed according to your selection.
     A window will appear reporting that the update has completed
     successfully & the new total cylinder number for the drives selected 
     will be displayed.

  8) You can now power down the system/drive.
