Welcome to Adaptec EZ-SCSI 4.02 
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

This readme is divided into 3 sections: Windows 95/NT, Windows 3.x
and DOS. Each section contains instructions on getting started, 
and specific tips for that Operating System(s). 
At the end of this file you will find a section on how to contact
Adaptec.

Windows 95 and NT

=-=-=-=-=-=-=-=-=

This section contains information on the following for
the above operating systems:

   A.) Getting Started
   B.) Help on installing Windows 95 from a SCSI CD-ROM
   C.) Help on installing NT on a SCSI hard drive
   D.) Installing Host Adapter Drivers (also called miniports)
   E.) Specific Host Adapter Driver Tips


A.) Getting Started
===================

   Insert the "Adaptec EZ-SCSI Setup Disk" into your floppy drive 
   and run SETUP.EXE.
   Follow the instructions.

   When the Adaptec EZ-SCSI installation is complete, please select the
   "EZ-SCSI README" option for additional information.

B.) Help on Installing Windows 95 from a SCSI CD-ROM
====================================================

   1. Run DOS Install as explained in the DOS section, and
   reboot. All the drivers needed to view your CD-ROM 
   drive will be loaded in config.sys, and you will be able
   to install Windows 95.

   (This of course assumes you had DOS already loaded on your
   system so that EZ-SCSI could load MSCDEX. If this file
   is not available you will be prompted for it by EZ-SCSI)

   2. Take note of the lines containing aspi*dos.sys and aspicd.sys
   in config.sys, and MSCDEX in autoexec.bat.
   
   3. Install Windows 95

   4. Say yes when it asks you should it create an emergency
   repair diskette for you. 

   5. When installation is complete you should copy the lines 
   noted in step 2 above into config.sys and autoexec.bat
   on this emergency diskette. This disk will allow you to
   reboot your system in an emergency and access your CD-ROM to 
   restore Windows 95.

C.) Help on Installing NT on a SCSI hard drive
==============================================
   If you do a floppyless install of NT 3.51 from 
   your SCSI CD-ROM using winnt /b, you may run into
   a blue screen the first time the NT Installer
   reboots your system. The reason for this is the
   installer cannot find your SCSI hard drive.
   You must reboot again, and just after the banner for
   NT appears, you have 2 seconds within which to
   press F6. This will pop up the screen that allows
   you to specify your SCSI host adapter. You should 
   specify Other and insert the EZ-SCSI setup floppy
   when it requests one. Then continue with the rest
   of the installation.
   
   This trick is also useful, if during installation
   you want NT to use the host adapter driver on the 
   EZ-SCSI setup disk instead of the usually older 
   embedded driver.

D.) Installing Host Adapter Drivers (also called miniports)
===========================================================

   What is a SCSI miniport?  A SCSI miniport is a device driver that controls
   your SCSI host adapter.  For example, if you are running Windows 95 with
   an Adaptec AHA-2940, the miniport driver you are using is named
   aic78xx.mpd.  Windows 95 and NT come with embedded drivers for most of
   Adaptec's host adapters. Included in this setup disk, are 
   newer Adaptec miniports.

   =-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-
   Automatic Installation by EZ-SCSI
   =-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-
  
   When you run Setup from this floppy, Adaptec EZ-SCSI will determine if the
   miniport driver included on this disk is newer than what you already have
   installed on your system.  If it is, your installed miniport driver will
   be automatically updated with the newer version.
   After EZ-SCSI completes its installation it will reboot your computer.
   Upon reboot, if your system doesn't yet see your host adapter, 
   you will need to take one of the following sets of steps, to complete
   the installation of the miniport driver on your system. The usual cause of
   this is a non plug and play host adapter, or a non plug and play O.S. such
   as NT.

   Additional Steps when Plug and Play doesn't work

   Windows 95
   ----------

   If you would like to manually update your SCSI miniport driver,
   simply follow these steps:

   1.)  Run Device Manager.  You can do this by moving the mouse pointer
        over "My Computer," clicking the right mouse button, and selecting
        the "Properties" menu option.
   2.)  Select the "Device Manager" option.
   3.)  Expand the "SCSI controllers" tree to view your SCSI host adapter(s).
   4.)  Double-click on your SCSI host adapter.
   5.)  Select the "Driver" option.
   6.)  Select the "Change Driver..." option.
   7.)  Select the "Have Disk..." option.
   8.)  Enter your floppy drive letter (e.g. A:\) as the location to copy
        the manufacturer's files from.
   9.)  Insert the Adaptec EZ-SCSI Setup Disk into your floppy drive and
        click "OK."
   10.) Select the name of your host adapter and click "OK."
   11.) Click "OK" and the driver will be copied to your hard drive.
   12.) You must restart your computer for the changes to take effect.
        Click "Yes" to restart your computer.  Click "No" to return to the
        System Properties window.

   NOTE:  The miniports may be manually updated by simply copying them to
          your Windows' IOSUBSYS subdirectory.  For example:

          C:\>copy a:\*.mpd c:\windows\system\iosubsys

   If you purchased the CD-ROM version of Windows 95, additional SCSI
   miniport drivers are located in the \Drivers\Storage directory of your
   Windows 95 CD-ROM.

   Windows NT 3.51
   ---------------
   1.) Open the Main program group
   2.) Click on the "Windows NT Setup" icon
   3.) Select "Add/Remove SCSI Adapters..."
   4.) Select "Add..."
   5.) Press OK to continue
   6.) On the Select SCSI Adapter Option dialog, scroll through
       the list of Adapters to the end and select "Other (Requires ...) "
   7.) At the "Insert Disk" dialog box make sure you have 
       inserted the EZ-SCSI Setup floppy into your floppy drive.
       Type a:\winnt and press OK.
   8.) Choose the host adapter you wish to add from the list in the 
      "Select OEM Option", and follow the rest of the dialogs.
   9.) You must restart your computer for the changes to take effect.


E.) Specific Host Adapter Driver Tips
=====================================
   The following non-standard command line option is available for AHA-2920 
   miniports in Windows 95 (FD16_700.MPD):

   DisableSynchronousTransfers=d+
      Where "d+" represents one or more decimal digits, each indicating a single
      SCSI target ID.  This option disables synchronous transfers 
      (SDTR negotiation) on the indicated SCSI target IDs.   
      For example,
         DisableSynchronousTransfers=245 
      turns off Synchronous Data Transfer Negotiations (and thus synchronous 
      transfers) on SCSI target IDs 2, 4, and 5.

   Adding options to Windows 95
   1.)  To add these options to the Windows 95 miniport driver, click the right
        mouse button once on the "My Computer" icon and select "Properties".  
        This will bring up the System Properties dialog box. 
   2.)  Select the "Device Manager" tab.
   3.)  Open the "SCSI Controllers" sub-tree, and select the 
        "Future Domain PCI SCSI Host Adapter" branch.
   4.)  Click on the "Properties" button.
   5.)  Select the "Settings" tab.
   6.)  Type the desired options in the "Adapter Settings" edit box, 
        separating each option with a semi-colon (;).

   You can also set other settings such as Disconnect Disable through the 
   Settings Tab of  the particular device whose properties you wish to alter.
   To disable the option, un-check the appropriate box in the Options group.  
   To enable the option, check the appropriate box in the Options group.


 The following non-standard command line options are available for AHA-2920 
 miniports in Windows NT 3.51 and higher (FD16_700.SYS):

   1.) Start the registry editor 
	From the Run command type x:\winnt\system32\regedt32.exe
	-where x is the drive where this directory is located.
        Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
   2.) Open the name of the particular miniport ("Fd16_700")
   3.) Create a key named "Parameters" using the "Edit"-->"Add Key" command.
   4.) Open "Parameters" and create a key named "Device"
   5.) Open "Device"
   6.) 
      a) To disable synchronous transfers, perform the "Edit"-->"Add Value" 
         command with the following information:
         Value Name:      DisableSynchronousTransfers
         Data Type:       REG_DWORD
         Value:           non-zero value to disable synchronous transfer

      b) To disable disconnects, perform the "Edit"-->"Add Value" command with the
         following information:
         Value Name:      DisableDisconnects
         Data Type:	  REG_DWORD
         Value:	     	  non-zero value to disable disconnects
    
      c) To set the maximum LUN to be scanned, perform the "Edit"-->"Add Value" 
         command with the following information:
         Value Name:      MaximumLogicalUnit
         Data Type:       REG_DWORD
         Value:           maximum LUN to scan up to (if one is entered, only LUN 0
                          will be scanned)
      
      d) To use the AdapterScansUp parameter, perform the "Edit"-->"Add Value" 
         command with the following information:
         Value Name:      DriverParameter
         Data Type:       REG_SZ
         Value:           AdapterScansUp=1
   7.) Exit the registry Editor and reboot the system

   Getting Started
   ===============

   CASE 1 - You are using a SCSI CD-ROM drive for the first time
   -------------------------------------------------------------
   Install the DOS version of EZ-SCSI first as described in the 
   DOS "Getting Started" section below. This will install
   the CD-ROM drivers so that you can access your CD-ROM, under 
   Windows 3.1/3.11 and DOS. Then follow the steps in CASE 2


   CASE 2 - You can see your CD-ROM in File Manager
   ------------------------------------------------
   Insert the "Adaptec EZ-SCSI Setup Disk" into your floppy drive 
   and run SETUP.EXE. Follow the instructions.


   CASE 3 - You do not have a CD-ROM drive
   ---------------------------------------
   You can install DOS EZ-SCSI in order to load the drivers that
   will allow you to use your SCSI removable drives such as IOMEGA
   ZIP and JAZ or the Syquest EZ 135.  
   However in order to install the many useful applications that come
   with EZ-SCSI you will need to order the floppy replacement diskettes from
   the number mentioned in the section "Contacting Adaptec".


   When EZ-SCSI completes installation, it copies over a larger 
   readme.txt to your EZ-SCSI directory with information on 
   supported host adapters, peripherals and some further tips.
   Since the file is too large for Notepad to handle, please use 
   DOS EDIT or Microsoft Write to view it.
