===========================================================
1) What is in this archive and what is required to
   install it.
===========================================================

This is the dBASE IV 1.5 disk set.  This version of dBASE
includes a fix that will allow it to work on faster
processors than earlier builds of dBASE IV 1.5.  Those
earlier builds would not reindex tables properly on fast
machines.  Re-indexing could lead to the error "File is
already open."  That is fixed in this version.

The files contained in this archive will install dBASE IV
1.5 build number XX71. You must already have dBASE IV 1.5
build number XX67 or build number XX69 in order to install
this version.  It is not sufficient to have dBASE IV 1.0
or 1.1 in order to install this version.  You must have
the serial number from the original floppies you used when
you installed dBASE IV 1.5, in order to install this
version of dBASE.

To check your build number, launch dBASE and at the dot
prompt type

   ? VERSION(1)

The response will include one of the three build numbers,
xx67, xx69 or xx71.

2) How to download this archive and prepare a set of
   installation diskettes from it.
===========================================================

Download the file dBIVxx71.EXE from

ftp://ftp.inprise.com/pub/VdBASE/devsupport/dbasedos/patches/db4/

Create a temporary directory on your hard disk and copy
dBIVxx71.EXE to it.  Change directories to this temporary
directory and run dBIVxx71.EXE.  This will create a copy of
this readme file, a file called FILELIST.TXT and five
subdirectories containing the install files.  The file list
shows what should be on the five floppy diskettes you will
create for the install files.


===========================================================
3) How to prepare a set of five floppy diskettes to hold
   the install files.
===========================================================

To install dBASE, you must create a set of five installation
diskettes.  The following process will erase any information
on any of the diskettes, so make sure either the diskettes
are empty, or they contain only unwanted files.

Write "Install Disk" on a label and stick it on the first
diskette.  Put the diskette in the floppy drive.  It must
be given a particular volume name, and be formatted to a
particular size.  If the floppy is not the "a" drive,
substitute the proper drive letter for a: in the
instructions that follow.  Type

   format a: /v:124000AS071 /f:720

This will format the diskette and give it a volume name of
124000AS071, and a capacity of 720 K.  Note that versions
of DOS on some windows machines may refuse to format a disk
for 720 K.  The error in that case will be "Invalid media
or Track 0 bad - disk unusable."  In that case, use windows
explorer to format the disk for 720 K, and with the proper
volume name.

Label the next diskette "System Disk 1."  Put it in the
drive and type

   format a: /v:124001AB071 /f:720

Label the next diskette "System Disk 2."  Put it in the
drive and type

   format a: /v:124002AB071 /f:720

Label the fourth diskette "System Disk 3."  Insert that
diskette and type

   format a: /v:124003AB071 /f:720

Label the last diskette "Sample Programs."  Put that in the
drive and type

   format a: /v:124010AB071 /f:720

You should now have the following five newly-formatted
floppy diskettes, with the following labels and volume
names:

     Disk label          Volume name

  1) Installation        124000AS071
  2) System Disk 1       124001AB071
  3) System Disk 2       124002AB071
  4) System Disk 3       124003AB071
  5) Sample Programs     124010AB071


===========================================================
4) Copying the install files to the floppy diskettes.
===========================================================

From the DOS prompt, change directories to be in the
temporary directory you created in step 2), above.  Change
directories from here into the dbaseiv subdirectory.  Put
the disk labeled "Install Disk" in the floppy drive.  Type

   xcopy /h disk1of5\*.* a:

This will copy all of the files from the directory disk1of5
to the floppy, including one hidden file.

Insert the floppy labeled "System Disk 1" and type

   xcopy /h disk2of5\*.* a:

Insert the floppy labeled "System Disk 2" and type

   xcopy /h disk3of5\*.* a:

Insert the floppy labeled "System Disk 3" and type

   xcopy /h disk4of5\*.* a:

Insert the floppy labeled "Sample Programs" and type

   xcopy /h disk5of5\*.* a:


The floppies should now contain the files listed in the
file FILELIST.TXT.  Note that the first four diskettes
should contain one hidden file each, and the fifth should
contain two hidden files.  To get a file listing of all the
files on one of these floppies, type

   dir /a:-d a:


===========================================================
5) Installing dBASE from the floppy diskettes.
===========================================================

Insert the floppy labeled "Install Disk."  Change
directories to the floppy drive and type

   install

The install program will prompt you for any information
required.  When it asks for a serial number, enter the
serial number you were issued with your original copy of
dBASE IV 1.5.

This will install dBASE IV 1.5 build number xx71.  After
the installation is complete, you can test for the build
number by following the directions for doing so, above.
