        help
          If you want to use one of the FAT-based file systems (the MS-DOS and
          VFAT (Windows 95) file systems), then you must say Y or M here
          to include FAT support. You will then be able to mount partitions or
          diskettes with FAT-based file systems and transparently access the
          files on them, i.e. MSDOS files will look and behave just like all
          other Unix files.

          This FAT support is not a file system in itself, it only provides
          the foundation for the other file systems. You will have to say Y or
          M to at least one of "MSDOS fs support" or "VFAT fs support" in
          order to make use of it.

          Another way to read and write MSDOS floppies and hard drive
          partitions from within Linux (but not transparently) is with the
          mtools ("man mtools") program suite. You don't need to say Y here in
          order to do that.

          If you need to move large files on floppies between a DOS and a
          Linux box, say Y here, mount the floppy under Linux with an MSDOS
          file system and use GNU tar's M option. GNU tar is a program
          available for Unix and DOS ("man tar" or "info tar").

          The FAT support will enlarge your kernel by about 37 KB. If unsure,
          say Y.

          To compile this as a module, choose M here: the module will be called
          fat.  Note that if you compile the FAT support as a module, you
          cannot compile any of the FAT-based file systems into the kernel
          -- they will have to be modules as well.

config MSDOS_FS
        tristate "MSDOS fs support"
        select FAT_FS
        help
          This allows you to mount MSDOS partitions of your hard drive (unless
          they are compressed; to access compressed MSDOS partitions under
          Linux, you can either use the DOS emulator DOSEMU, described in the
          DOSEMU-HOWTO, available from
          <http://www.tldp.org/docs.html#howto>, or try dmsdosfs in
          <ftp://ibiblio.org/pub/Linux/system/filesystems/dosfs/>. If you
          intend to use dosemu with a non-compressed MSDOS partition, say Y
          here) and MSDOS floppies. This means that file access becomes
          transparent, i.e. the MSDOS files look and behave just like all
          other Unix files.

          If you have Windows 95 or Windows NT installed on your MSDOS
          partitions, you should use the VFAT file system (say Y to "VFAT fs
          support" below), or you will not be able to see the long filenames
          generated by Windows 95 / Windows NT.

          This option will enlarge your kernel by about 7 KB. If unsure,
          answer Y. This will only work if you said Y to "DOS FAT fs support"
          as well. To compile this as a module, choose M here: the module will
          be called msdos.

config VFAT_FS
        tristate "VFAT (Windows-95) fs support"
        select FAT_FS
        help
          This option provides support for normal Windows file systems with
          long filenames.  That includes non-compressed FAT-based file systems
          used by Windows 95, Windows 98, Windows NT 4.0, and the Unix
          programs from the mtools package.

          The VFAT support enlarges your kernel by about 10 KB and it only
          works if you said Y to the "DOS FAT fs support" above.  Please read
          the file <file:Documentation/filesystems/vfat.txt> for details.  If
          unsure, say Y.

          To compile this as a module, choose M here: the module will be called
          vfat.

config FAT_DEFAULT_CODEPAGE
        int "Default codepage for FAT"
        depends on MSDOS_FS || VFAT_FS
        default 437
        help
          This option should be set to the codepage of your FAT filesystems.
          It can be overridden with the "codepage" mount option.
          See <file:Documentation/filesystems/vfat.txt> for more information.

config FAT_DEFAULT_IOCHARSET
        string "Default iocharset for FAT"
        depends on VFAT_FS
        default "iso8859-1"
        help
          Set this to the default input/output character set you'd
          like FAT to use. It should probably match the character set
          that most of your FAT filesystems use, and can be overridden
          with the "iocharset" mount option for FAT filesystems.
          Note that "utf8" is not recommended for FAT filesystems.
          If unsure, you shouldn't set "utf8" here.
          See <file:Documentation/filesystems/vfat.txt> for more information.

config NTFS_FS
        tristate "NTFS file system support"
        select NLS
        help
          NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.

          Saying Y or M here enables read support.  There is partial, but
          safe, write support available.  For write support you must also
          say Y to "NTFS write support" below.

          There are also a number of user-space tools available, called
          ntfsprogs.  These include ntfsundelete and ntfsresize, that work
          without NTFS support enabled in the kernel.

          This is a rewrite from scratch of Linux NTFS support and replaced
          the old NTFS code starting with Linux 2.5.11.  A backport to
          the Linux 2.4 kernel series is separately available as a patch
          from the project web site.

          For more information see <file:Documentation/filesystems/ntfs.txt>
          and <http://www.linux-ntfs.org/>.

          To compile this file system support as a module, choose M here: the
          module will be called ntfs.

          If you are not using Windows NT, 2000, XP or 2003 in addition to
          Linux on your computer it is safe to say N.

config NTFS_DEBUG
        bool "NTFS debugging support"
        depends on NTFS_FS
        help
          If you are experiencing any problems with the NTFS file system, say
          Y here.  This will result in additional consistency checks to be
          performed by the driver as well as additional debugging messages to
          be written to the system log.  Note that debugging messages are
          disabled by default.  To enable them, supply the option debug_msgs=1
          at the kernel command line when booting the kernel or as an option
          to insmod when loading the ntfs module.  Once the driver is active,
          you can enable debugging messages by doing (as root):
          echo 1 > /proc/sys/fs/ntfs-debug
          Replacing the "1" with "0" would disable debug messages.

          If you leave debugging messages disabled, this results in little
          overhead, but enabling debug messages results in very significant
          slowdown of the system.

          When reporting bugs, please try to have available a full dump of
          debugging messages while the misbehaviour was occurring.

config NTFS_RW
        bool "NTFS write support"
        depends on NTFS_FS
        help
          This enables the partial, but safe, write support in the NTFS driver.

          The only supported operation is overwriting existing files, without
          changing the file length.  No file or directory creation, deletion or
          renaming is possible.  Note only non-resident files can be written to
          so you may find that some very small files (<500 bytes or so) cannot
          be written to.

          While we cannot guarantee that it will not damage any data, we have
          so far not received a single report where the driver would have
          damaged someones data so we assume it is perfectly safe to use.

          Note:  While write support is safe in this version (a rewrite from
          scratch of the NTFS support), it should be noted that the old NTFS
          write support, included in Linux 2.5.10 and before (since 1997),
          is not safe.

          This is currently useful with TopologiLinux.  TopologiLinux is run
          on top of any DOS/Microsoft Windows system without partitioning your
          hard disk.  Unlike other Linux distributions TopologiLinux does not
          need its own partition.  For more information see
          <http://topologi-linux.sourceforge.net/>

          It is perfectly safe to say N here.

        help
        The sysfs filesystem is a virtual filesystem that the kernel uses to
        export internal kernel objects, their attributes, and their
        relationships to one another.

        Users can use sysfs to ascertain useful information about the running
        kernel, such as the devices the kernel has discovered on each bus and
        which driver each is bound to. sysfs can also be used to tune devices
        and other kernel subsystems.

        Some system agents rely on the information in sysfs to operate.
        /sbin/hotplug uses device and object attributes in sysfs to assist in
        delegating policy decisions, like persistently naming devices.

        sysfs is currently used by the block subsystem to mount the root
        partition.  If sysfs is disabled you must specify the boot device on
        the kernel boot command line via its major and minor numbers.  For

          greater than 4K are supported up to a maximum of 1 Mbytes (default

          (larger than 4GB), full uid/gid information, hard links and
          timestamps.  

          Squashfs is intended for general read-only filesystem use, for
          archival use (i.e. in cases where a .tar.gz file may be used), and in
          embedded systems where low overhead is needed.  Further information

          Sun added support for registering RPC services at an IPv6
          address by creating two new versions of the rpcbind protocol
          (RFC 1833).

          This option enables support in the kernel RPC server for
          registering kernel RPC services via version 4 of the rpcbind
          protocol.  If you enable this option, you must run a portmapper
          daemon that supports rpcbind protocol version 4.

          Serving NFS over IPv6 from knfsd (the kernel's NFS server)
          requires that you enable this option and use a portmapper that
          supports rpcbind version 4.

          If unsure, say N to get traditional behavior (register kernel
          RPC services using only rpcbind version 2).  Distributions
          using the legacy Linux portmapper daemon must say N here.

          SMB (Server Message Block) is the protocol Windows for Workgroups
          (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
          files and printers over local networks.  Saying Y here allows you to
          mount their file systems (often called "shares" in this context) and
          access them just like any other Unix directory.  Currently, this
          works only if the Windows machines use TCP/IP as the underlying
          transport protocol, and not NetBEUI.  For details, read
          <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
          available from <http://www.tldp.org/docs.html#howto>.

          Note: if you just want your box to act as an SMB *server* and make
          files and printing services available to Windows clients (which need
          to have a TCP/IP stack), you don't need to say Y here; you can use
          the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
          for that.

          General information about how to connect Linux, Windows machines and
          Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

          To compile the SMB support as a module, choose M here:
          the module will be called smbfs.  Most people say N, however.

          CONFIG_SMB_NLS_REMOTE.

          The nls settings can be changed at mount time, if your smbmount
          supports that, using the codepage and iocharset parameters.

          smbmount from samba 2.2.0 or later supports this.

          NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
          used by Novell NetWare clients to talk to file servers.  It is to
          IPX what NFS is to TCP/IP, if that helps.  Saying Y here allows you
          to mount NetWare file server volumes and to access them just like
          any other Unix directory.  For details, please read the file

          the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.

        help
          Coda is an advanced network file system, similar to NFS in that it
          enables you to mount file systems of a remote server and access them
          with regular Unix commands as if they were sitting on your hard
          disk.  Coda has several advantages over NFS: support for
          disconnected operation (e.g. for laptops), read/write server
          replication, security model for authentication and encryption,
          persistent client caches and write back caching.

          If you say Y here, your Linux box will be able to act as a Coda
          *client*.  You will need user level code as well, both for the
          client and server.  Servers are currently user level, i.e. they need
          no kernel support.  Please read
          <file:Documentation/filesystems/coda.txt> and check out the Coda
          home page <http://www.coda.cs.cmu.edu/>.

          To compile the coda client support as a module, choose M here: the
