Before You Install XDS
----------------------

Hardware Requirements

    CPU:     80386 minimum, 80486 or higher recommended
    Display: VGA minimum, SVGA recommended for XDS Environment
    RAM:     12MB minimum, 16MB or more recommended
    DASD:    In case of full installation:
                 Native XDS-x86 - 11.4MB
                 XDS-C          - 6.9MB
                 Both           - 15.2MB

Software Requirements

    Operating System: IBM OS/2 Warp Version 3 or OS/2 Warp Version 4

    For Native XDS-x86, no additional software is required. For XDS-C,
    an ANSI-compliant C compiler should be installed. XDS-C supports
    the following compilers out-of-the-box:

    IBM C Set++*
    IBM Visual Age C++*
    Watcom C/C++

    Manual setup would be required if another C compiler is used.


Getting Help
------------

    The documentation is shipped in Postscript format on a separate
    diskette or, in case of on-line distribution, in a zip file.
    Printed manuals are available from some distributors at extra cost.

    Select the "Documentation" component during install to have the
    on-line manuals installed. They will be available from the
    "XDS Information" subfolder.


Installing XDS
--------------

Installing Over Versions Prior to 2.21

    XDS-C for OS/2, versions prior to 2.21, did not have an install
    program; Native XDS-x86 v2.21 was also released without one first.
    If you have such a product, you have to either delete it manually 
    or install a new product to a different directory. In either case,
    ensure that new product's directories precede or replace old ones
    in PATH and BOOKSHELF environment variables and that XDSDIR points
    to a new product's installation directory.

    NOTE: if you have XDS Environment installed, you may wish to keep
    your profile. 

If You Have Another XDS Product Installed

    IMPORTANT: If you already have one or more XDS products installed,
               read the following notes carefully.

    1. Since XDS products share a number of files, they have to be
       installed in the same directory. So you will not be allowed
       to set installation directory. If you do not have enough disk
       space, you have to delete all XDS products and install them
       on a different drive.

    2. Names of all files copied to your hard disk during installation
       are initially FAT-compatible. There is a script which you might
       use to expand names of files corresponding to library modules
       to match module names (only in case of installation onto a file
       system which supports long file names, e.g. HPFS). To operate
       properly, the installation program SHRINKS FILE NAMES BACK
       to 8.3 convention BEFORE INSTALLING a new XDS product, so you
       may need to re-run that script after installation.

Floppy Disk Installation

    To install an XDS product from floppy disks, insert the disk labeled
    as first into your floppy drive and type

    A:
    INSTALL

    at the OS/2 command prompt, then follow the on-line instructions.

Archive Installation

    To install an electronically shipped product, create a temporary
    directory on your hard drive and unpack the downloaded archive
    into it, then type

    INSTALL

    at the OS/2 command prompt and follow the on-line instructions.
    
    You may also create installation floppies if you are short in disk
    space, or to make a backup, by running the MKDISKS.CMD script.

Adding And Removing Components

    Each XDS product consists of several components. During install,
    you are prompted to select the required components. You may add
    or remove components any time later by launching the INSTALL 
    program as described above and following the on-line instructions.
    Remove all components to remove the entire product.


Late-Breaking News
------------------

    XDS Environment, optionally included in Native XDS-x86 2.31 and
    XDS-C 2.31 packages, is at 2.21 level. The new IDE is currently 
    in beta and will be available for 2.31 users at no extra cost.


Service and Technical Support
-----------------------------

    Electronic support is provided for XDS products. To ask a technical
    question or report a suspected product defect, send an e-mail
    message to support@xds.ru, or fill in an on-line form available
    on XDS Web pages at http://www.xds.ru/xds/.

    A distributor may provide additional support, of which you should
    have been informed when you purchased your XDS product.
