    <title>Configuring Wine</title>
    <para>
      Now that you hopefully managed to successfully install
      the Wine program files,
      this chapter will tell you how to configure the Wine environment
      properly to run your Windows programs.
    </para>
    <para>
      First, we'll give you an overview about which kinds of
      configuration and program execution aspects a fully configured
      Windows environment has to fulfill in order to ensure that many
      Windows programs run successfully without encountering any
      misconfigured or missing items.
      Next, we'll show you which easy helper programs exist
      to enable even novice users to complete the Wine environment
      configuration in a fast and easy way.
      The next section will explain the purpose of the Wine configuration file,
      and we'll list all of its settings.
      After that, the next section will detail the most important and
      unfortunately most difficult configuration part:
      how to configure the file system and DOS drive environment that
      Windows programs need.
      In the last step we'll tell you how to establish a working Windows
      registry base.
      Finally, the remaining parts of this chapter contain descriptions
      of specific Wine configuration items that might also be
      of interest to you.

        <para>
          A Windows installation is a very complex structure. It consists of
          many different parts with very different functionality.
          We'll try to outline the most important aspects of it.

              of these directories are expected to exist. But unlike
              Unix directory structures, most of these locations are
              not hardcoded, and can be queried via the Windows API
              and the registry. This places additional requirements on
              a Wine installation.

              System DLLs. In Windows, these usually reside in the
              <filename>system</filename> (or
              <filename>system32</filename>) directory. Some Windows
              programs check for their existence in these
              directories before attempting to load them. While Wine
              is able to load its own internal DLLs
              (<filename>.so</filename> files) when the program
              asks for a DLL, Wine does not simulate the presence of
              non-existent files.

          While the users are of course free to set up everything
          themselves, the Wine team will make the automated Wine source
          installation script, <filename>tools/wineinstall</filename>,
          do everything we find necessary to do; running the
          conventional <userinput>configure && make depend && make && make
            install</userinput> cycle is thus not recommended, unless
          you know what you're doing. At the moment,
          <filename>tools/wineinstall</filename> is able to create a
          configuration file, install the registry, and create the
          directory structure itself.

        <para>
          The Wine configuration file is the central file to store
          configuration settings for Wine.
          This file (which is called <filename>config</filename>)
          can be found in the sub directory <filename>.wine/</filename>
          of your user's home directory
          (directory <filename>/home/user/</filename>). In other words, the Wine
          configuration file is <filename>~/.wine/config</filename>.
          Note that since the Wine configuration file is a part of the
          Wine registry file system, this file also
          <emphasis>requires</emphasis> a correct "WINE REGISTRY
          Version 2" header line to be recognized properly, just like
          all other Wine registry text files (just in case you decided
          to write your own registry file from scratch and wonder why
          Wine keeps rejecting it).

        <title>Creating Or Modifying The Configuration File</title>
        <para>
          If you just installed Wine for the first time and want to
          finish Wine installation by configuring it now, then you could
          use our sample configuration file <filename>config</filename>
          (which can be found in the directory
          <filename>documentation/samples/</filename> of the Wine source
          code directory) as a base for adapting the Wine configuration
          file to the settings you want.
          First, I should mention that you should not forget to make
          sure that any previous configuration file at
          <filename>~/.wine/config</filename> has been safely moved out
          of the way instead of simply overwriting it when you will now
          copy over the sample configuration file.
        </para>
        <para>
          If you don't have a pre-existing configuration file and thus
          need to copy over our sample configuration file to the
          standard Wine configuration file location, do in a
          <glossterm>terminal</glossterm>:
  <screen>
  <prompt>$ </><userinput>mkdir ~/.wine/</>
  <prompt>$ </><userinput>cp <replaceable>dir_to_wine_source_code</replaceable>/documentation/samples/config ~/.wine/config</>
  </screen>
          Otherwise, simply use the already existing configuration file
          at <filename>~/.wine/config</filename>.
        </para>
        <para>
          Now you can start adapting the configuration file's settings with an
          <glossterm>editor</glossterm> according to the documentation
          below.
          Note that you should <emphasis>only</emphasis> change
          configuration file settings if wineserver is not running (in
          other words: if your user doesn't have a Wine session running),
          otherwise Wine won't use them - and even worse, wineserver will
          overwrite them with the old settings once wineserver quits!!

            Sets the graphics driver to use for Wine output.
            x11drv is for X11 output, ttydrv is for text console output.
            WARNING: if you use ttydrv here, then you won't be able to run
            a lot of Windows GUI programs (ttydrv is still pretty "broken"
            at running graphical apps). Thus this option is mainly interesting
            for e.g. embedded use of Wine in web server scripts.
            Note that ttydrv is still very lacking, so if it doesn't work,
            resort to using "xvfb", a virtual X11 server.
            Another way to run Wine without display would be to run X11
            via Xvnc, then connect to that VNC display using xvncviewer
            (that way you're still able to connect to your app and
            configure it if need be).
          </para>
          <para>
            <programlisting>"Printer" = "off|on"</programlisting> Tells wine
            whether to allow printing via printer drivers to work.
            This option isn't needed for our built-in psdrv printer driver
            at all.
            Using these things are pretty alpha, so you might want to
            watch out. Some people might find it useful, however. If
            you're not planning to work on printing via windows printer
            drivers, don't even add this to your wine configuration file
            (It probably isn't already in it).
            Check out the [spooler] and [parallelports] sections too.
          </para>
          <para>
            <programlisting>"ShellLinker" = "wineshelllink"</programlisting>

            up Windows icons in e.g. KDE or Gnome that are given by programs
            making use of appropriate shell32.dll functionality to create
            icons on the desktop/start menu during installation.

            your wine is stripped.

            This section sets up wine's font handling.

          <para>
            <programlisting>"Resolution" = "96"</programlisting>
            Since the way X handles fonts is different from the way
            Windows does, wine uses a special mechanism to deal with
            them. It must scale them using the number defined in the
            "Resolution" setting. 60-120 are reasonable values, 96 is
            a nice in the middle one. If you have the real windows
            fonts available , this parameter will not be as
            important. Of course, it's always good to get your X fonts
            working acceptably in wine.
          </para>
          <para>
            <programlisting>"Default" = "-adobe-times-"</programlisting>
            The default font wine uses. Fool around with it if you'd like.
          </para>
          <para>
  OPTIONAL:
          </para>
          <para>
            The <literal>Alias</literal> setting allows you to map an X font to a font
            used in wine. This is good for apps that need a special font you don't have,
            but a good replacement exists. The syntax is like so:
            <programlisting>"AliasX" = "[Fake windows name],[Real X name]"&lt;,optional "masking" section></programlisting>
            Pretty straightforward. Replace "AliasX" with "Alias0",
            then "Alias1" and so on. The fake windows name is the name
            that the font will be under a windows app in wine. The
            real X name is the font name as seen by X (Run
            "xfontsel"). The optional "masking" section allows you to
            utilize the fake windows name you define. If it is not
            used, then wine will just try to extract the fake windows
            name itself and not use the value you enter.
          </para>
          <para>
            Here is an example of an alias without masking. The font will show up in windows
            apps as "Google".
            <programlisting>"Alias0" = "Foo,--google-"</programlisting>
            Here is an example with masking enabled. The font will show up as "Foo" in
            windows apps.
            <programlisting>"Alias1" = "Foo,--google-,subst"</programlisting>

          <para>
            The [spooler] section will inform wine where to spool
            print jobs. Use this if you want to try printing. Wine
            docs claim that spooling is "rather primitive" at this
            time, so it won't work perfectly. <emphasis>It is optional.</emphasis> The only
            setting you use in this section works to map a port (LPT1,
            for example) to a file or a command. Here is an example,
            mapping LPT1 to the file <filename>out.ps</filename>:
            <programlisting>"LPT1:" = "out.ps"</programlisting>
            The following command maps printing jobs to LPT1 to the
            command <command>lpr</command>. Notice  the |:
            <programlisting>"LPT1:" = "|lpr"</programlisting>
            The [ports] section is usually useful only for people who
            need direct port access for programs requiring dongles or

                  A boolean setting (default: <literal>Y</literal>)

                  NetBIOS name to the Unix host name of your computer, if
                  necessary truncated to 31 characters. The Unix hostname is the output

                  including the first dot ('.'). Among other things, this means that

          You can map a Windows fixed disc drive onto any node in your

          For example, you could map your Windows drive <filename>C:</filename>
          onto your Unix directory <filename>/usr/share/wine-C</filename>.
          Then the Windows folder <filename>C:\Windows\Fonts</filename> would

          Make sure that you have assigned drive letters for directories

          It is best to use a number of drive letters, and map them onto
          directories that cover small sections of the file system containing
          the files that Wine will need to access. This is safer than simply
          assigning a single drive letter to the Unix root directory 
          <filename></filename>/, which would allow Windows applications to
          access the whole of your Unix file system (subject, of course,
          to Unix permissions). If one of them misbehaved, or if you
          accidentally installed a virus, this might leave you vulnerable.

          For replaceable media, such as floppy discs and CD-ROMs, you should

        <para>
          The <filename>dosdevices</filename> directory contains the entries
          that tell Wine how to map Windows disc drive letters onto Unix file
          system nodes, and how to map Windows serial and parallel ports onto
          Unix devices. It is located in the <filename>.wine</filename>
          sub-directory of your home directory,
          i.e. <filename>~/.wine/dosdevices</filename>.

        <para>
          The entries in the <filename>dosdevices</filename> directory are
          symbolic links to Unix file system nodes and devices. You can
          create them by using the <command>ln</command> command in a Unix
          terminal. Alternatively, many File Managers have the capability of
          creating symbolic links.

        <para>
          For example, if you have decided to map your Windows

          Replaceable media are a little more complicated. In addition to

ln -s /mnt/floppy a:

          you also need to create a link for the device itself. Notice that

ln -s /dev/fd0 a::

        </para>
        <para>
          For serial and parallel ports, you simply create a link to

          This tells Wine and Windows programs where the
          <filename>Windows</filename> directory is.  It is
          recommended to have this directory somewhere on your
          configured <medialabel>C</medialabel> drive, and it's also
          recommended to just call the directory "windows" (this is
          the default setup on Windows, and some stupid programs
          might rely on this).  So in case you chose a "Windows"
          setting of "c:\\windows" and you chose to set up a drive C
          e.g. at <filename>/usr/local/wine_c</filename>, the
          corresponding directory would be
          <filename>/usr/local/wine_c/windows</filename>.  Make one
          if you don't already have one. <emphasis>No trailing slash</emphasis> (<emphasis>not</emphasis>
          <filename>C:\\windows\</filename>)! Write access strongly
          recommended, as Windows programs always assume write access

        </para>
        <para>
          <programlisting>"System" = "c:\\windows\\system"</programlisting>
          This sets up where the windows system files are. The Windows
            system directory should reside below the directory used for the
          <literal>Windows</literal> setting.
            Thus when using the example above, the system directory would be
            <filename>/usr/local/wine_c/windows/system</filename>.
          Again, no trailing slash, and write access!
        </para>

          <programlisting>"Temp" = "c:\\temp"</programlisting> This should
          be the directory you want your temp files stored in,

        <para>
          <programlisting>"Path" = "c:\\windows;c:\\windows\\system;c:\\blanco"</programlisting>
          Behaves like the <envar>PATH</envar> setting on UNIX

            sol.exe</userinput>, if <filename>sol.exe</filename>
          resides in a directory specified in the
          <literal>Path</literal> setting, wine will run it (Of
          course, if <filename>sol.exe</filename> resides in the
          current directory, wine will run that one). Make sure it
          always has your <filename>windows</filename> directory and
          system directory (For this setup, it must have
          <filename>"c:\\windows;c:\\windows\\system"</filename>).

        <para id="dirsymlinks">
          <programlisting>"ShowDirSymlinks" = "1"</programlisting>
          Wine doesn't pass directory symlinks to Windows programs by
          default, as doing so may crash some programs that do
          recursive lookups of whole subdirectory trees
          whenever a directory symlink points back to itself or one of its
          parent directories.
          That's why we disallowed the use of directory symlinks
          and added this setting to reenable ("1") this functionality.
          If you <emphasis>really</emphasis> need Wine to take into
          account symlinked directories, then reenable it, but
          <emphasis>be prepared for crashes</emphasis> in certain
          Windows programs when using the above method! (in other words:
          enabling it is certainly not recommended)

        <title>More detailed explanation about file system differences</title>
        <para>
          Windows uses a different (and inferior) way than Unix to describe the
          location of files in a computer. Thus Windows programs also expect
          to find this different way supported by the system.
          Since we intend to run Windows programs on
          a Unix system, we're in trouble, as we need to translate
          between these different file access techniques.
        </para>
        <para>
          Windows uses drive letters to describe drives or
          any other form of storage media and to access files on them.
          For example, common drive names are
          <filename>C:</filename> for the main Windows system partition
          on the first harddisk and <filename>A:</filename> for the
          first floppy drive.
          Also, Windows uses <filename>\</filename> (backslash) as the
          directory separator sign, whereas Unix uses
          <filename>/</filename> (slash).
          Thus, an example document on the first data partition in
          Windows might be accessed by the name of
          <filename>D:\mywork\mydocument.txt</filename>.
        </para>
        <para>
          So much for the Windows way of doing things.
        </para>
        <para>
          Well, the problem is, in Unix there is no such thing as
          <quote>drive letters</quote>. Instead, Unix chose to go the
          much better way of having one single uniform directory tree
          (starting with the root directory
          <filename>/</filename>), which has various storage devices
          such as e.g. harddisk partitions appended at various directory
          locations within the tree (an example would be
          <filename>/data1/mywork</filename>, which is the first data
          partition mounted/attached to a directory called data1 in the
          root directory <filename>/</filename>; mywork is a sub
          directory of the data partition file system that's mounted
          under <filename>/data1</filename>).
          In Unix, the Windows example document mentioned above could e.g.
          be accessed by the name of
          <filename>/data1/mywork/mydocument.txt</filename>,
          provided that the administrator decided to mount (attach) the first
          data partition at the directory /data1 inside the Unix
          directory tree. Note that in Unix, the administrator can
          <emphasis>choose</emphasis> any custom partition location he
          wants (here, <filename>/data1</filename>), whereas in Windows the system
          <emphasis>selects</emphasis> any drive letter it deems
          suitable for the first data partition (here,
          <filename>D:</filename>), and, even worse, if there is some
          change in partition order, Windows automatically
          <emphasis>changes</emphasis> the drive letter, and you might
          suddenly find yourself with a first data partition at drive
          letter <filename>E:</filename>, with all the file naming and
          referencing confusion that entails. Thus, the Windows way of
          using ever-changing drive letters is <emphasis>clearly
          inferior</emphasis> to the Unix way of assigning
          <emphasis>fixed</emphasis> directory tree locations for every
          data storage medium.
          As we'll see soon, fortunately this Windows limitation of
          changing drive letters doesn't affect us in Wine at all, since
          we can properly map <emphasis>never-changing</emphasis> drive letters to <emphasis>fixed</emphasis> locations inside the Unix directory tree (and even if the location of the respective Unix directory changes, we can still simply update the Wine drive mapping to reflect the updated location and at the same time keep the original drive letter).
        </para>
        <para>
          OK, now that we know some theory about Windows and Unix drive
          and filename mapping, it's probably time to ask how Wine
          achieves the magic of mapping a Unix directory location to a
          Windows drive...
        </para>
        <para>
          Wine chose to do the following:
          In Wine, you don't assign some real physical storage medium
          (such as a harddisk partition or similar) to each drive letter
          mapping entry.
          Instead, you choose certain sub directory trees inside the Unix
          directory tree (that starts with <filename>/</filename>) that
          you would like to assign a drive letter to.
        </para>
        <para>
          Note that for every Unix sub directory tree that you intend to
          start Windows programs in, it is <emphasis>absolutely
          required</emphasis> to have a Wine drive mapping entry:
        </para>
        <para>
          For example, if you had a publicly writable <quote>Windows
          directory space</quote> under <filename>/usr/mywine</filename>, then in order to be
          able to access this sub directory tree from Wine, you should
          have a drive mapping entry that maps a certain drive letter
          (for example, let's take drive letter <filename>P:</filename>)
          either to <filename>/usr/mywine</filename> or <filename>/usr</filename> (to also access any directories belonging to the parent directory) or <filename>/</filename> (to also access any directory whatsoever on this system by this drive letter mapping). The DOS drive/directory location to access files in <filename>/usr/mywine</filename> <emphasis>in Wine</emphasis> in these configuration cases would then be <filename>P:\</filename> or <filename>P:\mywine</filename> or <filename>P:\usr\mywine</filename>, respectively.

        <title>Installing Wine Using An Existing Windows Partition As Base</title>
        <para>
          Some people intend to use the data of an existing Windows partition
        with Wine in order to gain some better compatibility or to run already
        installed programs in a setup as original as possible.
        Note that many Windows programs assume that they have full write
        access to all windows directories.

        This means that you either have to configure the Windows
        partition mount point for write permission by your Wine user
        (see <link linkend="config-drive-vfat">Dealing with FAT/VFAT partitions</link>
        on how to do that), or you'll have to copy over (some parts of) the Windows
        partition content to a directory of a Unix partition and make
        sure this directory structure is writable by your user.
        We <emphasis>HIGHLY DISCOURAGE</emphasis> people from directly using a Windows partition with
        write access as a base for Wine!! (some programs, notably
        Explorer, corrupt large parts of the Windows partition in case
        of an incorrect setup; you've been warned).
        Not to mention that NTFS write support in Linux is still very
        experimental and <emphasis>dangerous</emphasis> (in case you're using an NT-based
        Windows version using the NTFS file system).
        Thus we advise you to go the Unix directory way.

        <para>
          This document describes how FAT and
          VFAT file system permissions work in Linux
          with a focus on configuring them for Wine.
        </para>

        <sect3>
          <title>Introduction</title>
          <para>
            Linux is able to access DOS and Windows file systems using
            either the FAT (older 8.3 DOS filesystems) or VFAT (newer
            Windows 95 or later long filename filesystems) modules.
            Mounted FAT or VFAT filesystems provide the primary means
            for which existing programs and their data are accessed
            through Wine for dual boot (Linux + Windows) systems.
          </para>
          <para>
            Wine maps mounted FAT file systems, such as
            <filename>/c</filename>, to drive letters, such as
            <quote>c:</quote>, by means of symbolic links in the
            <link linkend="config-drive-sections"><filename>dosdevices</filename></link>
            directory. Thus, in your dosdevices directory, you could type
            the command:
          <programlisting>
ln -s /c c:
          </programlisting>
          </para>
          <para>
            Although VFAT filesystems are preferable to FAT filesystems
            for their long filename support, the term <quote>FAT</quote>
            will be used throughout the remainder of this document to
            refer to FAT filesystems and their derivatives. Also,
            <quote>/c</quote> will be used as the FAT mount point in
            examples throughout this document.
          </para>
          <para>
            Most modern Linux distributions either detect or allow
            existing FAT file systems to be configured so that they can be
            mounted, in a location such as <filename>/c</filename>,
            either persistently (on bootup) or on an as needed basis. In
            either case, by default, the permissions will probably be
            configured so that they look like:

          <para>

            group and are only writable by "root"
            (<literal>755</literal> permissions). This is restrictive in
            that it requires that Wine be run as root in order for

          <title>Running Wine as root</title>
          <para>
            Running Wine as root is the easiest and most thorough way of giving
            programs that Wine runs unrestricted access to FAT files systems.
            Running wine as root also allows programs to do things unrelated
            to FAT filesystems, such as listening to ports that are less than
            1024.  Running Wine as root is dangerous since there is no limit to
            what the program can do to the system, so it's <emphasis>HIGHLY DISCOURAGED</emphasis>.
          </para>
        </sect3>

        <sect3>
          <title>Mounting FAT filesystems</title>
          <para>
            The FAT filesystem can be mounted with permissions less restrictive
            than the default.  This can be done by either changing the user that
            mounts the FAT filesystem or by explicitly changing the permissions
            that the FAT filesystem is mounted with.  The permissions are
            inherited from the process that mounts the FAT filesystem.  Since the
            process that mounts the FAT filesystem is usually a startup script
            running as root the FAT filesystem inherits root's permissions.  This
            results in the files on the FAT filesystem having permissions similar
            to files created by root.  For example:
          </para>
  <screen>
  <prompt>~></prompt><userinput>whoami</userinput>
  <computeroutput>root</computeroutput>
  <prompt>~></prompt><userinput>touch root_file</userinput>
  <prompt>~></prompt><userinput>ls -l root_file</userinput>
  <computeroutput></computeroutput>-rw-r--r--   1 root     root            0 Dec 10 00:20 root_file
  </screen>
          <para>
            which matches the owner, group and permissions of files seen
            on the FAT filesystem except for the missing 'x's.  The
            permissions on the FAT filesystem can be changed by changing
            root's umask (unset permissions bits).  For example:
          </para>
  <screen>
  <prompt>~></prompt><userinput>umount /c</userinput>
  <prompt>~></prompt><userinput>umask</userinput>
  <computeroutput>022</computeroutput>
  <prompt>~></prompt><userinput>umask 073</userinput>
  <prompt>~></prompt><userinput>mount /c</userinput>
  <prompt>~></prompt><userinput>cd /c</userinput>
  <prompt>/c></prompt><userinput>ls -l</userinput>
  <computeroutput>-rwx---r--   1 root     root           91 Oct 10 17:58 autoexec.bat
  -rwx---r--   1 root     root          245 Oct 10 17:58 config.sys
  drwx---r--  41 root     root        16384 Dec 30  1998 windows</computeroutput>
  </screen>
          <para>
            Mounting the FAT filesystem with a umask of
            <literal>000</literal> gives all users complete control over
            it. Explicitly specifying the permissions of the FAT
            filesystem when it is mounted provides additional control.
            There are three mount options that are relevant to FAT
            permissions: <literal>uid</literal>, <literal>gid</literal>
            and <literal>umask</literal>.  They can each be specified
            when the filesystem is manually mounted.  For example:
          </para>
  <screen>
  <prompt>~></prompt><userinput>umount /c</userinput>
  <prompt>~></prompt><userinput>mount -o uid=500 -o gid=500 -o umask=002 /c</userinput>
  <prompt>~></prompt><userinput>cd /c</userinput>
  <prompt>/c></prompt><userinput>ls -l</userinput>
  <computeroutput>-rwxrwxr-x   1 sle      sle            91 Oct 10 17:58 autoexec.bat
  -rwxrwxr-x   1 sle      sle           245 Oct 10 17:58 config.sys
  drwxrwxr-x  41 sle      sle         16384 Dec 30  1998 windows</computeroutput>
  </screen>
          <para>
            which gives "sle" complete control over
            <filename>/c</filename>.  The options listed above can be
            made permanent by adding them to the
            <filename>/etc/fstab</filename> file:
          </para>
  <screen>
  <prompt>~></prompt><userinput>grep /c /etc/fstab</userinput>
  <computeroutput>/dev/hda1  /c  vfat  uid=500,gid=500,umask=002,exec,dev,suid,rw 1 1</computeroutput>
  </screen>
          <para>
            Note that the umask of <literal>002</literal> is common in
            the user private group file permission scheme.  On FAT file
            systems this umask assures that all files are fully
            accessible by all users in the specified user group
            (<literal>gid</literal>).
          </para>
        </sect3>

        <sect3>
          <title>Shadowing FAT filesystems</title>
          <para>
            Shadowing provides a finer granularity of control.  Parts of
            the original FAT filesystem can be copied so that the
            program can safely work with those copied parts while
            the program continues to directly read the remaining
            parts.  This is done with symbolic links. For example,
            consider a system where a program named
            <application>AnApp</application> must be able to read and
            write to the <filename>c:\windows</filename> and
            <filename>c:\AnApp</filename> directories as well as have
            read access to the entire FAT filesystem.  On this system
            the FAT filesystem has default permissions which should not
            be changed for security reasons or can not be changed due to
            lack of root access.  On this system a shadow directory
            might be set up in the following manner:
          </para>
  <screen>
  <prompt>~></prompt><userinput>cd /</userinput>
  <prompt>/></prompt><userinput>mkdir c_shadow</userinput>
  <prompt>/></prompt><userinput>cd c_shadow</userinput>
  <prompt>/c_shadow></prompt><userinput>ln -s /c_/* .</userinput>
  <prompt>/c_shadow></prompt><userinput>rm windows AnApp</userinput>
  <prompt>/c_shadow></prompt><userinput>cp -R /c_/{windows,AnApp} .</userinput>
  <prompt>/c_shadow></prompt><userinput>chmod -R 777 windows AnApp</userinput>
  <prompt>/c_shadow></prompt><userinput>perl -p -i -e 's|/c$|/c_shadow|g' ~/.wine/config</userinput>
  </screen>
          <para>
          The above gives everyone complete read and write access to
          the <filename>windows</filename> and
          <filename>AnApp</filename> directories while only root has
          write access to all other directories.

          Reading labels and serial numbers just works automatically
          if you specify the correct symbolic links for the devices
          (with double colons after the drive letters) in your
          <link linkend="config-drive-sections"><filename>dosdevices</filename></link>

          If you don't want to read labels and serial numbers directly from

          <filename>.windows-serial</filename> respectively. These are
          simple ASCII files that you can create with any text editor;
          the label can be set to any string you like, the serial

<title>DLL Overrides</title>

<para>
  The wine configuration file directives [DllDefaults]
  and [DllOverrides] are the subject of some confusion. The
  overall purpose of most of these directives are clear enough,
  though - given a choice, should Wine use its own built-in
  DLLs, or should it use <filename>.DLL</filename> files found
  in an existing Windows installation? This document explains
  how this feature works.

  <title>The [DllPairs] section</title>
  <para>
    At one time, there was a section called [DllPairs] in the
    default configuration file, but this has been obsoleted
    because the pairing information has now been embedded into
    Wine itself. (The purpose of this section was merely to be
    able to issue warnings if the user attempted to pair
    codependent 16-bit/32-bit DLLs of different types.) If you
    still have this in your <filename>~/.wine/config</filename> or
    <filename>wine.conf</filename>, you may safely delete it.

<sect3>
  <title>The [DllOverrides] section</title>
  <para>
    This section specifies how you want specific DLLs to be
    handled, in particular whether you want to use "native" DLLs
    or not, if you have some from a real Windows configuration.
    Because built-ins do not mix seamlessly with native DLLs yet,
    certain DLL dependencies may be problematic, but workarounds
    exist in Wine for many popular DLL configurations. Also see
    WWN's [16]Status Page to figure out how well your favorite
    DLL is implemented in Wine.
  </para>
  <para>
    It is of course also possible to override these settings by
    explicitly using Wine's <parameter>--dll</parameter>
    command-line option (see the man page for details).  Some
    hints for choosing your optimal configuration (listed by

<sect2 id="config-system-dlls">
<title>System DLLs</title>
<para>
  The Wine team has determined that it is necessary to create
  fake DLL files to trick many programs that check for
  file existence to determine whether a particular feature
  (such as Winsock and its TCP/IP networking) is available. If
  this is a problem for you, you can create empty files in the
  configured <filename>c:\windows\system</filename> directory
  to make the program think it's there, and Wine's built-in DLL
  will be loaded when the program actually asks for it.
  (Unfortunately, <filename>tools/wineinstall</filename> does
  not create such empty files itself.)
</para>
<para>
  Applications sometimes also try to inspect the version
  resources from the physical files (for example, to determine
  the DirectX version). Empty files will not do in this case,
  it is rather necessary to install files with complete
  version resources. This problem is currently being worked
  on. In the meantime, you may still need to grab some real
  DLL files to fool these apps with.
</para>
<para>
  And there are of course DLLs that wine does not currently
  implement very well (or at all). If you do not have a real
  Windows you can steal necessary DLLs from, you can always
  get some from one of the Windows DLL archive sites
  that can be found via internet search engine.
  Please make sure to obey any licenses on the DLLs you fetch...
  (some are redistributable, some aren't).
</para>
</sect2>

<sect2 id="config-dll-missing">
<title>Missing DLLs</title>

<para>
  In case Wine complains about a missing DLL, you should check whether
  this file is a publicly available DLL or a custom DLL belonging
  to your program (by searching for its name on the internet).
  If you managed to get hold of the DLL, then you should make sure
  that Wine is able to find and load it.
  DLLs usually get loaded according to the mechanism of the
  SearchPath() function.
  This function searches directories in the following order:

  <orderedlist>
    <listitem>
      <para>
        The directory the program was started from.
      </para>
    </listitem>
    <listitem>
      <para>
        The current directory.
      </para>

    <listitem>
      <para>
        The PATH variable directories.
      </para>
    </listitem>
  </orderedlist>

  In short: either put the required DLL into your program
  directory (might be ugly), or usually put it into the Windows system
  directory. Just find out its directory by having a look at the Wine
  configuration file variable "System" (which indicates the location of the
  Windows system directory) and the associated drive entry.
  Note that you probably shouldn't use NT-based native DLLs,
  since Wine's NT API support is somewhat weaker than its Win9x
  API support (thus leading to even worse compatibility with NT DLLs
  than with a no-windows setup!), so better use Win9x native DLLs
  instead or no native DLLs at all.

<title>Configuring the graphics driver (x11drv, ttydrv etc.)</title>

<para>
Wine currently supports several different display subsystems
(graphics / text) that are available on various operating
systems today.
For each of these, Wine implements its own interfacing driver.
This section explains how to select one of these drivers
and how to further configure the respective driver.
Once you're finished with that, you can consider your Wine installation
to be finished.
</para>

<para>
The display drivers currently implemented in Wine are:
x11drv, which is used for interfacing to X11 graphics
(the one you'll most likely want to use) and ttydrv
(used for text mode console apps mainly that don't really need
any graphics output).
Once you have decided which display driver to use, it is chosen
with the <literal>GraphicsDriver</literal> option in the
[wine] section of <filename>~/.wine/config</filename>.
</para>

<sect2>
<title>Configuring the x11drv graphics driver</title>

<sect3>
  <title>x11drv modes of operation</title>

  <para>
    The x11drv driver consists of two conceptually distinct
    pieces, the graphics driver (GDI part), and the windowing
    driver (USER part). Both of these are linked into the
    <filename>libx11drv.so</filename> module, though (which you
    load with the <literal>GraphicsDriver</literal> option). In
    Wine, running on X11, the graphics driver must draw on
    drawables (window interiors) provided by the windowing
    driver. This differs a bit from the Windows model, where the
    windowing system creates and configures device contexts
    controlled by the graphics driver, and programs are
    allowed to hook into this relationship anywhere they like.
    Thus, to provide any reasonable tradeoff between
    compatibility and usability, the x11drv has three different
    modes of operation.

          windows will just be Wine-drawn windows inside the
          Wine-provided desktop window (which will itself be
          managed by your window manager), and Windows
          programs can roam freely within this virtual
          workspace and think they own it all, without
          disturbing your other X apps.
        Note: currently there's one desktop window for every
        program; this will be fixed at some time.

<title>Setting the Windows and DOS version value</title>

<para>
The windows and DOS version value a program gets e.g. by calling the
Windows function GetVersion() plays a very important role:
If your Wine installation for whatever reason fails to provide
to your program the correct version value that it expects,
then the program might assume some very bad things and fail (in
the worst case even silently!).

Fortunately Wine contains some more or less intelligent Windows
version guessing algorithm that will try to guess the Windows
version a program might expect and pass that one on to the
program.

Thus you should <emphasis>not</emphasis> lightly configure a version value, as this will be a "forced" value and thus turn out to be rather harmful to proper operation. In other words: only explicitly set a Windows version value in case Wine's own version detection was unable to provide the correct Windows version and the program fails.

      <title>Using ODBC</title>
      <para>
        This section describes how ODBC works within Wine and how to configure it.
      </para>
      <para>
        The ODBC system within Wine, as with the printing system, is designed
        to hook across to the Unix system at a high level.  Rather than
        ensuring that all the windows code works under wine it uses a suitable
        Unix ODBC provider, such as UnixODBC.  Thus if you configure Wine to
        use the built-in odbc32.dll, that Wine DLL will interface to your
        Unix ODBC package and let that do the work, whereas if you configure
        Wine to use the native odbc32.dll it will try to use the native
        ODBC32 drivers etc.
      </para>
      <sect2>
        <title>Using a Unix ODBC system with Wine</title>
        <para>
          The first step in using a Unix ODBC system with Wine is, of course,
          to get the Unix ODBC system working itself.  This may involve
          downloading code or RPMs etc.  There are several Unix ODBC systems
          available; the one the author is used to is unixODBC (with the
          IBM DB2 driver). Typically such systems will include a tool, such
          as <command>isql</command>, which will allow you to access the data from the command
          line so that you can check that the system is working.
        </para>
        <para>
          The next step is to hook the Unix ODBC library to the wine built-in
          odbc32 DLL.  The built-in odbc32 (currently) looks to the
          environment variable <emphasis>LIB_ODBC_DRIVER_MANAGER</emphasis>
          for the name of the ODBC library.  For example in the author's
          .bashrc file is the line:
        </para>
        <programlisting>
export LIB_ODBC_DRIVER_MANAGER=/usr/lib/libodbc.so.1.0.0
        </programlisting>
        <para>
          If that environment variable is not set then it looks for a
          library called libodbc.so and so you can add a symbolic link to
          equate that to your own library.  For example as root you could
          run the commands:
        </para>
        <screen>
<prompt># </prompt><userinput>ln -s libodbc.so.1.0.0 /usr/lib/libodbc.so</userinput>
<prompt># </prompt><userinput>/sbin/ldconfig</userinput>
        </screen>
        <para>
          The last step in configuring this is to ensure that Wine is set up
          to run the built-in version of odbc32.dll, by modifying the DLL
          configuration.  This built-in DLL merely acts as a stub between the
          calling code and the Unix ODBC library.
        </para>
        <para>
          If you have any problems then you can use WINEDEBUG=+odbc32 command
          before running wine to trace what is happening.  One word of 
          warning. Some programs actually cheat a little and bypass the ODBC 
          library. For example the Crystal Reports engine goes to the registry 
          to check on the DSN.  The fix for this is documented at unixODBC's
          site where there is a section on using unixODBC with Wine.

      <sect2>
        <title>Using Windows ODBC drivers</title>
        <para>
          Native ODBC drivers have been reported to work for many types of 
          databases including MSSQL and Oracle. In fact, some like MSSQL can 
          only be accessed on Linux through a Winelib app.   Rather than
          just copying DLL files, most ODBC drivers require a Windows-based
          installer to run to properly configure things such as registry keys.
        </para>
        <para>
          In order to set up MSSQL support you will first need to download
          and run the mdac_typ.exe installer from microsoft.com.  In order to 
          configure your ODBC connections you must then run CLICONFG.EXE and 
          ODBCAD32.EXE under Wine.  You can find them in the windows\system
          directory after mdac_typ runs.  Compare the output of these programs
          with the output on a native Windows machine.  Some things, such
          as protocols, may be missing because they rely on being installed
          along with the operating system.  If so, you may be able to copy
          missing functionality from an existing Windows installation as
          well as any registry values required.  A native Windows installation
          configured to be used by Wine should work the same way it did
          when run natively.
