			DRIVER INSTALLATION PROCEDURE

+---------------------------------------------------------------------------+


    +------------------------+
    |			     |
    |	 WINDOWS DRIVERS     |
    |			     |
    +------------------------+

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

  The files PTICTRL.386 and PTI13.386 are disk drivers for Microsoft
  Windows 3.10 and 3.11 for the DC-4030VL Disk Accelerator.

  Use of these two files are optional. Your DC-4030VL-2 is fully plug-in
  compatible with Windows 32 bit Disk and File Access.

  These drivers provide the following functions:

  1. support for the DC4030VL-2 as the PRIMARY controller with more than
     two hard drives attached
  2. support for the DC-4030VL-2 as the SECONDARY disk controller
  3. support for the DC4030VL-2 under Windows in the event you
     encounter difficulties using 32-bit disk or 32-bit file access with
     the default Microsoft drivers

  Please follow the steps below to install the driver for the DC-4030VL-2.
  Step 1 and 2 are not needed when only ONE Promise
  controller is installed as the PRIMARY disk controller with one
  (drive 0) or two (drive 0,1) IDE drive(s) attached.

  All these operations can be performed under DOS.

  1. Install the DOS driver

     Copy DOSDRV.SYS to your system with the appropriate path.

     Add Device = [drive:][\path\] DOSDRV.SYS in the CONFIG.SYS file.
     Note: This statement must precede any other statement which would
     access the physical drive(s) supported by this driver.

     If your mainboard CPU has a 16-bit external bus (for example, IBM
     486 SLC2), add the /W parameter to the statement.

  2. Reboot the system.

  3. Copy the drivers PTICTRL.386 and PTI13.386 to your system in
     the appropriate path.

     It is recommended that the drivers PTICTRL.386 and PTI13.386
     be copied to the Windows SYSTEM directory.

  4. Go to the SYSTEM.ini file found in your Windows directory.
     Check if the following line exist in the [386Enh] section of
     your SYSTEM.ini file:

     [386Enh]
     32BitDiskAccess=ON

     If the statement does not exist, add it into the [386Enh] section.
     If the statement exists, but 32BitDiskAccess is set to "OFF", you
     need to change it to "ON".

     The SYSTEM.ini file can be edited by using a txt editor or by using
     SYSEDIT.EXE utility in Windows.

  5. Delete the command lines "device=*wdctrl" and "device=*int13"
     from the [386Enh] section of your SYSTEM.INI file, if they exist.

  6. Install the virtual devices "PTICTRL.386" and "PTI13.386".

     Add the following command lines in the [386Enh] section of the
     SYSTEM.INI file:

     device=[drive:][\path\]PTICTRL.386
     device=[drive:][\path\]PTI13.386

     The [drive:] and [\path\] point to the directory that contains
     PTICTRL.386 file and PTI13.386. Note that the setting must specify
     the full path of the device drivers.

  7. If your mainboard CPU has a 16-bit data access bus (for example, IBM
     486 SLC2), add this additional statement:

     DisksAccessMode= /W

     Adding this additional statement configures the controller to work
     in 16-bit data access mode.  Certain motherboard CPUs have a 16-bit
     external data bus and require this setting (for example, IBM 486
     SLC2). If no parameter is specified, the controller will function
     under the default 32-bit data access mode.


  Start Windows to activate the drivers.

    |	   OS/2 DRIVERS     |
    |			    |
    +-----------------------+

  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)

  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.


  The drivers for NetWare 3.X can be found on this diskette under the
  subdirectory NetWare.  There are two drivers in this directory:

  PTIA310.DSK for NetWare 3.10
  PTIA311.DSK for NetWare 3.11

  These drivers provide the following functions:

  1. 32-bit access and block mode transfer under NetWare 3.1X
  2. Support for the DC4030VL-2 as the PRIMARY controller with
     more than two hard drives attached
  3. Support for the DC4030VL-2 as a SECONDARY disk controller

  Please follow the steps below to install the drivers for NetWare 3.1X.
  Remember that PTIA310.DSK is for NetWare 3.10 and that PTIA311.DSK is
  for NetWare 3.11.  The driver, ISADISK.DSK, provided by NetWare should
  be substituted with our drivers in the NetWare installation.

  After installing the DC4030VL-2 as a PRIMARY disk controller:

  1. Bring up the NetWare server until the ":" prompt appears on the screen
  2. Type the following command after the prompt

  load PTIA310 port=1f0 int=e[/W]

  Remember that PTIA310.DSK is for NetWare 3.10 and PTIA311.DSK is for
  NetWare 3.11.

  Adding the /W parameters configures the controller to work in 16-bit data
  access mode.	Certain motherboard CPUs have a 16-bit external data bus
  and require this setting(for example the IBM 486 SLC2).  If no parameter
  is specified, the controller will function under the default 32-bit data
  access mode.


  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.

  1. Bring up the NetWare server until the ":" prompt appears
  2. Type the following command after the prompt if your DC4030VL-2 is at
     IRQ12

     load PTIA310 port=170 int=c[/W]

  3. Type the following command after the prompt if your DC4030VL-2 is at
     IRQ15

     load PTIA310 port=170 int=f[/W]

  Remember that PTIA310.DSK is for NetWare 3.10 and that PTIA311.DSK is for
  NetWare 3.11.

  Adding the /W parameter configures the controller to work in 16-bit data
  access mode.	Certain motherboard CPUs have a 16-bit external data bus
  path and require this setting(for example the IBM 486 SLC2).	If no
  parameter is specified, the controller will function under the default
  32-bit data access mode.

	 please type the following commands to copy
	 the installation shell script from diskette to hard disk.

	# cd /tmp
	# doscp -m b:/unix/ptiinst .
	# sh ./ptiinst b:


   3. During installation, it will ask another blank diskette.
      Please insert that diskette as requested.

   4. The system will ask you for the IRQ of the secondary hard
      disk controller by the following question:

	 If you will install one Promise caching controller
	  as the secondary hard disk controller,
	  what is the IRQ of the secondary hard disk controller
	  in this system (12 or 15)? (default=15)

      Please choose the appropriate one according to the jumper setting
      of that controller.

   5. Done! if you are running AT&T UNIX SVR 4.0.

   6. If you are running SCO UNIX, type the following commands after
      the driver is installed.

	 # cd /
	 # shutdown -y -g0 -i6

      The commands will shutdown and reboot your system with the new kernel.

   NOTICE:
    1.) Primary controller means the hard disk controller with
	IRQ 14, and secondary controller is the hard disk
	controller with IRQ 12 or 15.
    2.) If you will install two Promise caching controller
	in the same system, please read the following:
	. After the machine has been powered on and the controller
	  has checked its memory size, you can press the function
	  key <F2> to enter the setup menu.  Then, press <F1> to
	  enter the Set-up Configuration submenu. Now you are ready
	  to setup the BIOS starting address.
	. The BIOS starting address of each Promise controller must
	  be different.
	  For example, you can set one BIOS starting address to be
	  dc000, and another to be c8000.


  ******** Add Secondary Hard Disks *******

  If you have attached more than one hard disk to the cable, you must
  do the following things to make this hard disk "visible" to the system.

  1. Please type the following command:

     # ptidiskadd

  2. The command will ask you of the following three questions:

	Which controller will the hard disk be attached to?

	 1. the primary controller
	 2. the secondary controller

	Please choose answer(1 or 2)(default=1):

	Which cable (of this controller) will the hard disk be attached to?

	 1. the first cable
	 2. the second cable

	Please choose the answer(1 or 2)(default=1):

	Will the hard disk be the master(single) or slave drive on this cable?

	 1. the master or single hard disk
	 2. the slave hard disk

	Please choose the answer(1 or 2)(default=2):

     Please answer the questions according to your setting.

  4. The other steps are very similar to the procedures about
     "Adding secondary hard disks" presented in the System Administor's
     Guide of SCO UNIX Operating System. Please refer to the System
     Administor's Guide for further reference.

  NOTICE:
  1.) When using the ptidiskadd, you MUST set the
      Promise controller to "cache disabled".
      With "cache disabled", the system will be able to identify the
      bad sector of the hard disk.
  2.) This utility will not work until you install the
      Promise driver and reboot with the new kernel.
  3.) With both primary and secondary Promise controller installed,
      you can add up to 8 hard disks.


  ******** Remove the Driver ********

  If you want to remove the driver and recover to the original hard disk
  device driver, please type the following command after the prompt #:

	 # removepkg

  Certain installed package name(s) will be displayed on the screen.
  Please choose "Promise Caching Controller Driver"
  The remove procedure will continue.

			 COEXISTENCE EXPLANATION

+==========================================================================+


  This section of the Readme file is designed for those that are going to
  be installing two DC4030VL-2 controllers in the same system.	The following steps
  are written for this explicit purpose.  If you want to install the
  DC4030VL-2 as a SECONDARY controller, please see the User Manual that came
  with your DC4030VL-2.

  Be certain that the PRIMARY DC4030VL-2 is set at
  "Dual Controller[Primary]".  This needs to be done in the CSU setup.
  We recommend that you install the primary card first and change the
  settings so that they do not interfere with the default settings of the
  SECONDARY.  Be certain the SECONDARY DC4030VL-2 is set at
  "Dual Controller[Secondary]".  This needs to be done in the CSU setup.
  These changes should be made before going to the following steps.

  BEFORE MAKING ANY CHANGES TO YOUR SYSTEM TURN OFF THE CACHE ON THE
  DC4030VL-2.  FAILURE TO DO SO CAN RESULT IN INCOMPLETE INSTALLATION.

  1. Install both your PRIMARY and SECONDARY controllers in your PC
  2. Connect all the cables and drives
  3. Power on the system and press F2 when the CSU prompt of the PRIMARY
     controller is displayed:

     Primary Controller: Firmware V3.0, BIOS V3.0
     DriveCache DC4030VL-2:Cache Memory Test(Hit A Key To Abort).....K
     Press F2 to Enter Cache Setup Utility

     If you did not enter the Cache Setup Utility of the PRIMARY controller
     by pressing F2, the CSU prompt message of the SECONDARY controller will
     be displayed on the screen:

     Secondary Controller: Firmware V3.0, BIOS V3.0
     DriveCache DC4030VL-2: Cache Memory Test(Hit A Key To Abort).....K
     Press F2 to Enter Cache Setup Utility

	     +------------------------------------------------+
	     |	 The CSU prompt of the SECONDARY controller   |
	     |	 might appear on the screen before that of    |
	     |	 the PRIMARY.  The sequence depends on the    |
	     |	 BIOS address of each controller.	      |
	     +------------------------------------------------+


  Be certain that the IRQ's or BIOS addresses do not interfere with any
  other cards in your system.  If in the event they do you may have trouble
  at bootup.
