This disk set contains the OrCAD ESP Design Environment version 4.20 (ESP).

To install ESP, change drives to the desired high density floppy drive 
containing the ESP disk (I.E. type A: followed by the Enter key).  Then
type INSTALL at the command prompt.  The install program will ask you to
answer some questions that will enable you to customize the installation
of ESP on your PC.


ADDITIONAL NOTES:

    ------------
    Using FIXDAT
    ------------
  

FIXDAT is a program that transfers configuration information from older  
versions of ESP to newer versions--eliminating the need to reconfigure
tool sets, local configurations, and the on/off status of Transfers after
updating the software.  

When you install your new product or update, you are asked--at the 
beginning of the installation process--if you want to automatically update
the ORCADESP.DAT files in your design directories.  If you answer "YES," 
INSTALL runs a program called FIXDAT.  INSTALL automatically handles
the details and updates your configuration information.

FIXDAT is designed to run properly when the OrCAD directory structure is
found on one disk drive and the environment variables are set to point
to the proper directories.  If you ask INSTALL to run FIXDAT, and FIXDAT 
cannot find the files it needs (either because more than one disk is used or
environment variables do not point to the proper directories), it reports 
an error. In these cases, you can run FIXDAT as a separate program from the 
system command prompt. If you do not run FIXDAT when you install your update,
the ORCADESP.DAT file is copied to a TEMPLATE directory on the disk drive 
you specified as the drive on which to install the OrCAD software.  
FIXDAT takes two arguments:  

o     The path and filename of the old ORCADESP.DAT file to update.  
      In this discussion, the file to update is called the oldDATfile.  

o     The path and filename of the new ORCADESP.DAT file.  In this 
      discussion, this is called the newDATfile.  

This is how FIXDAT works:  

1.  First, FIXDAT reads in newDATfile followed by oldDATfile.  

2.  Then FIXDAT compares the two files and finds buttons in newDATfile
    that have the same name as buttons in oldDATfile.  If it finds a match, it
    copies the local configuration setting from oldDATfile to newDATfile. 
    When FIXDAT is through with the comparison, you have a new newDATfile
    that has all of oldDATfile's local configuration settings.   

3.  FIXDAT then replaces oldDATfile with the updated newDATfile.  

    Note that if the newDATfile has new buttons in it that don't exist in the
    oldDATfile, the local configuration settings for the new buttons are set to
    OrCAD's defaults.  

------------------------------------------------------------------ 
Syntax  

FIXDAT [oldDATfile newDATfile] [switches]  

      Updates oldDATfile so that it has all of the buttons found in        
      newDATfile.  The settings in oldDATfile remain unchanged.  

/A   Reads the ORCADPROJ environment variable to find the TEMPLATE        
     design directory.  The ORCADESP.DAT files in ALL of the design        
     directories are updated to the version of the ORCADESP.DAT file in        
     the TEMPLATE design.  oldDATfile and newDATfile are not specified        
     when the /A switch is used.  

/L   Reads the ORCADPROJ environment variable to find the TEMPLATE        
     design directory.  The ORCADESP.DAT file in the current directory        
     only is updated to the version of the ORCADESP.DAT file in the        
     TEMPLATE design directory.  oldDATfile and newDATfile are not        
     specified when the /L switch is used.  

/U   Does the transfer even if oldDATfile and newDATfile are already       
     the same version.  The /U switch can be used in conjunction with the
     /L switch or /A switch.  If so, oldDATfile and newDATfile are not
     specified.  

      NOTE: FIXDAT reports an error if either newDATfile or oldDATfile        
            does not exist.  

------------------------------------------------------------------ 
Examples  

The next sections describe how to use FIXDAT to:  

o     Update all your ORCADESP.DAT files  

o     Update TEMPLATE's data file and data files in selected designs  

o     Update one ORCADESP.DAT file  

------------------------------------------------------------------ 
Update all your ORCADESP.DAT files  

If your directory structure is standard and you want to update all your
data files, follow these steps:  

1.  Change to the TEMPLATE design and enter this command:  

      C:\ORCAD\TEMPLATE>fixdat orcadesp.dat orcadesp.NEW  

    ORCADESP.DAT is the data file with all your current configuration
    settings.  ORCADESP.NEW is the data file with the latest updates to the
    design environment, and is saved in the TEMPLATE directory only when
    FIXDAT is not run during installation.  This command updates your data
    file to the new version without losing your configuration settings.  

2.  To update the data file in each design, enter this line from anywhere in
    the directory structure:  

      C:\>fixdat /a  

3.  Delete ORCADESP.NEW from your TEMPLATE design to prevent copying it
    to new designs.  If you allow INSTALL to automatically update the
    ORCADESP.DAT files, INSTALL automatically deletes ORCADESP.NEW for
    you.  

------------------------------------------------------------------ 
Update TEMPLATE's data file and data files in selected designs  

1.  Change to the TEMPLATE design and enter this line:  

      C:\ORCAD\TEMPLATE>fixdat orcadesp.dat orcadesp.NEW  

    Again, ORCADESP.DAT is the data file with all your current configuration  
    settings.  ORCADESP.NEW is the data file with the latest updates to the
    design environment, and is saved in the TEMPLATE directory only when
    FIXDAT is not run during installation.  This command updates TEMPLATE's 
    data file to the new version without losing your configuration settings.  

2.  Change to the design containing the ORCADESP.DAT file you want to
    update.  

3.  Enter this line at the prompt:  

      C:\ORCAD\YOURDESN>fixdat /L  

4.  Repeat steps 2 and 3 for each design you need to update.  

5.  Delete ORCADESP.NEW from your TEMPLATE design to prevent copying it
    to new designs.  

------------------------------------------------------------------ 
Update one ORCADESP.DAT file  

To update a data file in a specific design without updating any other data  
files, follow these steps:  

1.  Copy the new data file ORCADESP.NEW to a floppy disk.  In this example, 
    the floppy disk is in drive A.  

2.  Delete ORCADESP.NEW from your TEMPLATE design.  

3.  Enter this line:  

      C:\>fixdat \orcad\yourdesn\orcadesp.dat a:\orcadesp.NEW  

    FIXDAT updates ORCADESP.DAT in the YOURDESN design to match the
    version of ORCADESP.NEW in the A: drive.  


    ------------------------------------
    ESP ADDITIONAL TECHNICAL INFORMATION
    ------------------------------------


1. In order to run OrCAD executables from outside of the ESP environment 
   you must first add a statement to your AUTOEXEC.BAT file. This line 
   tells the OrCAD executables which driver to load. If you used a VGA
   driver, you would add the following line:

   SET ORCADDD=C:\ORCADESP\DRV\VGA640.DRV

   This assumes that you had installed the default directories onto 
   your C: drive.

2.  If special video drivers are created using the GENDRIVE utility
    these drivers will not be displayed in the configuration scroll 
    boxes.  To select your custom driver, delete the existing 
    driver selected and type in the custom driver name.
