1config FAT_FS
2	tristate
3	select NLS
4	help
5	  If you want to use one of the FAT-based file systems (the MS-DOS and
6	  VFAT (Windows 95) file systems), then you must say Y or M here
7	  to include FAT support. You will then be able to mount partitions or
8	  diskettes with FAT-based file systems and transparently access the
9	  files on them, i.e. MSDOS files will look and behave just like all
10	  other Unix files.
11
12	  This FAT support is not a file system in itself, it only provides
13	  the foundation for the other file systems. You will have to say Y or
14	  M to at least one of "MSDOS fs support" or "VFAT fs support" in
15	  order to make use of it.
16
17	  Another way to read and write MSDOS floppies and hard drive
18	  partitions from within Linux (but not transparently) is with the
19	  mtools ("man mtools") program suite. You don't need to say Y here in
20	  order to do that.
21
22	  If you need to move large files on floppies between a DOS and a
23	  Linux box, say Y here, mount the floppy under Linux with an MSDOS
24	  file system and use GNU tar's M option. GNU tar is a program
25	  available for Unix and DOS ("man tar" or "info tar").
26
27	  The FAT support will enlarge your kernel by about 37 KB. If unsure,
28	  say Y.
29
30	  To compile this as a module, choose M here: the module will be called
31	  fat.  Note that if you compile the FAT support as a module, you
32	  cannot compile any of the FAT-based file systems into the kernel
33	  -- they will have to be modules as well.
34
35config MSDOS_FS
36	tristate "MSDOS fs support"
37	select FAT_FS
38	help
39	  This allows you to mount MSDOS partitions of your hard drive (unless
40	  they are compressed; to access compressed MSDOS partitions under
41	  Linux, you can either use the DOS emulator DOSEMU, described in the
42	  DOSEMU-HOWTO, available from
43	  <http://www.tldp.org/docs.html#howto>, or try dmsdosfs in
44	  <ftp://ibiblio.org/pub/Linux/system/filesystems/dosfs/>. If you
45	  intend to use dosemu with a non-compressed MSDOS partition, say Y
46	  here) and MSDOS floppies. This means that file access becomes
47	  transparent, i.e. the MSDOS files look and behave just like all
48	  other Unix files.
49
50	  If you have Windows 95 or Windows NT installed on your MSDOS
51	  partitions, you should use the VFAT file system (say Y to "VFAT fs
52	  support" below), or you will not be able to see the long filenames
53	  generated by Windows 95 / Windows NT.
54
55	  This option will enlarge your kernel by about 7 KB. If unsure,
56	  answer Y. This will only work if you said Y to "DOS FAT fs support"
57	  as well. To compile this as a module, choose M here: the module will
58	  be called msdos.
59
60config VFAT_FS
61	tristate "VFAT (Windows-95) fs support"
62	select FAT_FS
63	help
64	  This option provides support for normal Windows file systems with
65	  long filenames.  That includes non-compressed FAT-based file systems
66	  used by Windows 95, Windows 98, Windows NT 4.0, and the Unix
67	  programs from the mtools package.
68
69	  The VFAT support enlarges your kernel by about 10 KB and it only
70	  works if you said Y to the "DOS FAT fs support" above.  Please read
71	  the file <file:Documentation/filesystems/vfat.txt> for details.  If
72	  unsure, say Y.
73
74	  To compile this as a module, choose M here: the module will be called
75	  vfat.
76
77config FAT_DEFAULT_CODEPAGE
78	int "Default codepage for FAT"
79	depends on MSDOS_FS || VFAT_FS
80	default 437
81	help
82	  This option should be set to the codepage of your FAT filesystems.
83	  It can be overridden with the "codepage" mount option.
84	  See <file:Documentation/filesystems/vfat.txt> for more information.
85
86config FAT_DEFAULT_IOCHARSET
87	string "Default iocharset for FAT"
88	depends on VFAT_FS
89	default "iso8859-1"
90	help
91	  Set this to the default input/output character set you'd
92	  like FAT to use. It should probably match the character set
93	  that most of your FAT filesystems use, and can be overridden
94	  with the "iocharset" mount option for FAT filesystems.
95	  Note that "utf8" is not recommended for FAT filesystems.
96	  If unsure, you shouldn't set "utf8" here.
97	  See <file:Documentation/filesystems/vfat.txt> for more information.
