				  Version 2.14	       	    July 22, 1994



* This release has been tested with OS/2 Version 2.1 and Beta Version 2.99


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

    \OS2\QL40.DDP     	Device driver profile script required for the OS/2
    			Device Driver Install utility

    \OS2\QL40CHK.EXE	Adapter presence-check program invoked by the OS/2
    			Device Driver Install utility

    \OS2\QL40OS2.ADD	OS/2 ADD driver for QLogic Fast!SCSI/QLA400 adapters

    \OS2\README.TXT	This file


* To initially install OS/2 on a SCSI disk attached to the Fast!SCSI/QLA400
  or to install OS/2 from a CD-ROM player attached to the Fast!SCSI/QLA400:

    1. Make a copy of the IBM OS/2 Diskette 1
    2. Copy the QL40OS2.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=QL40OS2.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 


* To install the QLogic Fast!SCSI/QLA400 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" and the installation of the ADD driver
       will proceed automatically
    7. 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=QL40OS2.ADD /!R
