OS/2 README FILE

BEFORE INSTALLING THE DRIVERS OR MAKING ANY CHANGES; TURN OFF THE CACHE
  ON THE DC4030VL-2.  FAILURE TO DO SO CAN RESULT IN INCOMPLETE INSTALLATION.

  BEFORE LEAVING OS/2 EACH TIME BACK UP THE FOLLOWING 3 FILES:
  1: CONFIG.SYS
  2: OS2.INI
  3: OS2SYS.INI

  The driver for OS/2 2.0 and 2.1 can be found on this disk under the
  subdirectory OS/2. There is one driver in this directory:

  PTI1S506.ADD

  You will need this driver to provide the following:

  1. 32-bit access and block transfer mode
  2. support for the DC4030VL-2 as the PRIMARY controller with more than
     two hard drives attached
  3. support for the DC4030VL-2 as the SECONDARY controller

  RECOMMENDED PARTITION SETUP

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

  If your DC4030VL-2 is installed as the PRIMARY controller, hard drives
  D2 and D3(the third and fourth hard drives) attached to the second
  connector should be partitioned as LOGICAL UNITS.

  If your DC4030VL-2 is installed as the SECONDARY controller, ALL hard
  drive partitions on the controller should be created as LOGICAL UNITS.

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

  1. Back up all necessary data stored on D2 and D3

  2. Delete the selected PRIMARY partition(s)
     (You can use the SIFDISK.EXE utility on this 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 the steps under "DRIVER INSTALLATION" below)

  4. Create the 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

  6. Restore the data

  DRIVER INSTALLATION

  Please follow the steps below in installing the drives for the DC4030VL-2.

  1. Copy PTI1S506.ADD to the OS/2 directory of your system. For example,
     if the OS/2 is in drive C, copy the driver to C:\OS2.

  2. Add BASEDEV=PTI1S506.ADD to your Config.SYS file using a text editor
     (this statement must not have either a drive or a path specified)

     If your motherboard CPU has a 16-bit external bus(for example the IBM
     486 SLC2), change this statement to:

     BASEDEV=PTI1S506.ADD/W

     Certain motherboard CPUs have a 16-bit external bus and require this
     setting.  If no parameter is specified, the controller will function
     under the default 32-bit data access mode.

  3. Delete the line "BASEDEV=IBM1S506.ADD" from the Config.SYS

  4. Save the setting and REBOOT the system

  To install the DC4030VL-2 as a SECONDARY disk controller, refer to
  the Users Manual that came with the DC4030VL-2 under SECONDARY
  CONTROLLER INSTALLATION first. If you have already loaded the OS/2
  drivers for the DC4030VL-2 and made the changes in the CSU then the
  DC4030VL-2 is ready to act as a SECONDARY controller.

  Notice:
  Please don't use DC4030VL-2 with D0 and D2/D3 but no D1 for OS/2, because
  the PTI1S506.ADD does not support this condition.

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

  /V :Verbose - display driver information at bootup
  /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
  /W :16-bit data transfer(for DC4030VL-2 only)
