QLogic Fast!SCSI IQ PCI ADD Driver for OS/2

				Version 2.02	       	  January 9, 1995



* This release has been tested with OS/2 Version 2.1 and OS/2 Warp Version 3


* The following files are on this disk for supporting OS/2:

    \OS2\QL10.DDP     	Device driver profile script required for the OS/2
    			Device Driver Install utility

    \OS2\QL10OS2.ADD	OS/2 ADD driver for QLogic Fast!SCSI IQ PCI adapters

    \OS2\README.TXT	This file


* To initially install OS/2 on a SCSI disk attached to the Fast!SCSI IQ PCI
  adapter or to install OS/2 from a CD-ROM player attached to the Fast!SCSI
  IQ PCI adapter:

  Installing OS/2 Version 2.1:

    1. Make a copy of the IBM OS/2 Diskette 1 (use diskcopy command)
    2. Copy the QL10OS2.ADD file from the \OS2 directory on the QLogic driver
       diskette onto the root directory on the copy of the OS/2 Diskette 1
    3. Edit the CONFIG.SYS file located on the copy of OS/2 Diskette 1, add
       the following statement to the end of the file:

       		BASEDEV=QL10OS2.ADD

    4. Start the installation by inserting the IBM OS/2 Installation
       Diskette into drive A and restarting the system, use the modified
       copy of Diskette 1 when prompted to insert Diskette 1 

  Installing OS/2 Warp Version 3 from CD-ROM:

    1. Make a copy of the IBM OS/2 Warp Diskette 1 (use diskcopy command)
    2. To make room for the QLogic driver, delete the following files from
       the copy of Diskette 1:

          For an ISA/EISA (non-Micro Channel) computer, delete:  IBM2*.*
          For a Micro Channel computer, delete:  IBM1*.*

    3. Copy the QL10OS2.ADD file from the \OS2 directory on the QLogic driver
       diskette onto the root directory on the copy of the OS/2 Diskette 1
    4. Edit the CONFIG.SYS file located on the copy of OS/2 Diskette 1:
       a. Insert the letters REM before any lines in the CONFIG.SYS that refer
          to the files deleted in step 2 above
       b. Add the following statement to the end of the file:

       		BASEDEV=QL10OS2.ADD

    5. Start the installation by inserting the IBM OS/2 Installation
       Diskette into drive A and restarting the system, use the modified
       copy of Diskette 1 when prompted to insert Diskette 1 

  Installing OS/2 Warp Version 3 from diskettes:

    1. Start the installation by inserting the IBM OS/2 Installation
       Diskette into drive A and restarting the system, insert other
       diskettes as requested
    2. During the installation from diskette, select "Advanced Installation"
    3. When the System Configuration window is displayed, select the CD-ROM
       Device Support icon and then select the type of CD-ROM device to be
       supported
    4. After completing the OS/2 installation from diskettes, follow the
       procedure below to install the QLogic ADD driver using the Device
       Driver Install utility


* To install the QLogic Fast!SCSI IQ PCI ADD driver on previously installed
  OS/2 system:

    1. Boot up OS/2 system
    2. Insert QLogic SCSI driver diskette into drive A (or B)
    3. Select "System Setup" from OS/2 System program group
    4. Select "Device Driver Install" from the System Setup group
    5. Change source directory to A:\OS2 (or B:\OS2)
    6. Select "Install"
    7. Select the "QLogic Fast!SCSI IQ PCI ADD Driver" followed by "OK". The
       driver will be copied to your boot disk and your CONFIG.SYS file will
       be updated 
    8. You must reboot your system after installing the driver


* OS/2 currently does not support removable SCSI disk devices.  The QLogic
  ADD driver provides limited support for these devices by treating them
  like a fixed disk device.  The disk media must be inserted when booting
  OS/2, and the system must be rebooted when changing the disk media.  To
  enable removable disk support, add the /!R parameter to the BASEDEV=
  command in your CONFIG.SYS file as follows:

       		BASEDEV=QL10OS2.ADD /!R


* The following command line parameters are supported by the QLogic
  Fast!SCSI IQ PCI ADD driver:  (add to end of BASEDEV=QL10OS2.ADD line
  in config.sys file)

  /A:d		Specifies which adapter (0-2) that following command line
  		parameters apply to.

  /I		Ignore the specified adapter (must follow "/A:d" parameter).

  /DM  /!DM	Enable/disable DASD manager support for specified adapter
		and/or devices (add ":d,d,d" to specify list of SCSI IDs or
		":(d,d),(d,d),(d,d)" to specify ID,LUN pairs).  Default is
		enabled.

  /SM  /!SM	Enable/disable SCSI manager support for specified adapter
		and/or devices (add ":d,d,d" to specify list of SCSI IDs or
		":(d,d),(d,d),(d,d)" to specify ID,LUN pairs).  Default is
		enabled.

  /!R		Report removable disk devices to OS/2 as fixed disks.
  		By default removable disks will be reported as removable.

  /SR  /!SR	Enable/disable SCSI bus reset during boot on specified
		adapter.  Default is enabled.  Do not disable the SCSI bus
		reset if synchronous negotiation is enabled on any device.

  /ET  /!ET	Enable/disable embedded target support for specified adapter.
		Default is enabled (all 8 LUNs supported).  Specify /!ET for
		supporting LUN 0 only.

  /V		Enable verbose mode (display configuration data during boot).
		Default is disabled.

  /RA           Reorder adapters.  This parameter is used to reverse the order
                in which the Fast!SCSI PCI Basic adapters are configured.
                This parameter is required on some systems with AMI BIOS and
		more than one Fast!SCSI PCI Basic adapters.
