DC-200/DC-200M OS/2 Driver README File            Version 1.02


     +====================================================+
     |    IBM OS/2 2.x disk driver for DC-200/DC-200M     |
     +====================================================+


     PTI1S506.ADD is the driver for IBM OS/2 2.0 and IBM OS/2 2.1.

     You will only need this driver under the following situations:

     - You want to install TURBO MODE under OS/2.
     - Your DC-200/DC-200M is installed with more than two IDE drives
       attached.



     RECOMMENDED PARTITION SETUP

     PRIMARY Partitions should be created on ONLY THE FIRST TWO HDs.  These
     recommendations are made to avoid changing the original OS/2 assigned
     drive order. The error message "Cannot Find COUNTRY.SYS" is a symptom
     of this setup problem.

     If your DC-200/DC-200M is installed as the PRIMARY controller, Hard Drives
     D2 and D3 (i.e. the "THIRD" and "FOURTH" HDs) attached to the second
     connector should be partitioned as LOGICAL UNITS.

     If your DC-200/DC-200M is installed as the SECONDARY controller, ALL HD
     partitions on the controller should be created as LOGICAL UNITS.


     These are the steps to recreate PRIMARY partitions as LOGICAL UNITS.

     1. Backup the data.

	Backup any necessary data stored on D2 and/or D3.

     2. Delete the selected PRIMARY partition(s).

	Delete the PRIMARY partition(s) created on D2 and/or D3. From a DOS
	BOOT, use the "SIFDISK.EXE" utility from the PROMISE DOS Utility
	diskette to accomplish this.

	WARNING: Deleting partitions will destroy data.  Be careful to
	select the correct drive partition(s) you wish to delete.


     3. Install the PTI1S506.ADD driver in OS/2.

	Follow steps under the "DRIVER INSTALLATION" below.

     4. Create partitions as LOGICAL UNIT(s).

	Open the "Drives" folder in the OS/2 desktop and run the FIXED DISK
	UTILITY.  Partition the drive(s) as LOGICAL.

     5. Format the partitions.

	Proceed to Format the new partitions.

     6. Restore data.

	Restore the backed up data onto the partitions.



     DRIVER INSTALLATION

     Please follow the steps below in installing the driver for DC-200/DC-200M.

     1. Install the OS/2 driver.

	Copy PTI1S506.ADD to the OS2 directory of your system.

	Use a text editor to edit the CONFIG.SYS file. Add a line as
	follows:

	BASEDEV = PTI1S506.ADD

	Note: This statement must not contain either drive or path
	      information.

     2. Delete the "BASEDEV = IBM1S506.ADD" device setting.

	Delete the command line "BASEDEV = IBM1S506.ADD" from the
	CONFIG.SYS file, if it exists.

     3. Reboot the system.



   The following switches are available on this driver and may apply to
   your system:

   /V    : Verbose - display driver information at initial time
   /A    : Adapter index - the ordering of adapters
   /I    : Ignore adapter - driver will not initialize the adapter indicated
   /<!>R : Reset adapter - enable or disable reset
   /<!>DM: DASD Manager support - enable or disable IBM-supplied DASD device
	   manager
   /U    : Unit number - the fixed disk drive number
   /T    : drive Timeout - the total allowable error recover time


  Notice:
  Drives must be installed sequentially.  Drives D0 and D1 must first be 
  installed before D2 and D3 can be accessed.
