6 | If you want to use one of the FAT-based file systems (the MS-DOS and | |
7 | VFAT (Windows 95) file systems), then you must say Y or M here | |
8 | to include FAT support. You will then be able to mount partitions or | |
9 | diskettes with FAT-based file systems and transparently access the | |
10 | files on them, i.e. MSDOS files will look and behave just like all | |
11 | other Unix files. | |
12 | ||
13 | This FAT support is not a file system in itself, it only provides | |
14 | the foundation for the other file systems. You will have to say Y or | |
15 | M to at least one of "MSDOS fs support" or "VFAT fs support" in | |
16 | order to make use of it. | |
17 | ||
18 | Another way to read and write MSDOS floppies and hard drive | |
19 | partitions from within Linux (but not transparently) is with the | |
20 | mtools ("man mtools") program suite. You don't need to say Y here in | |
21 | order to do that. | |
22 | ||
23 | If you need to move large files on floppies between a DOS and a | |
24 | Linux box, say Y here, mount the floppy under Linux with an MSDOS | |
25 | file system and use GNU tar's M option. GNU tar is a program | |
26 | available for Unix and DOS ("man tar" or "info tar"). | |
27 | ||
28 | The FAT support will enlarge your kernel by about 37 KB. If unsure, | |
29 | say Y. | |
30 | ||
31 | To compile this as a module, choose M here: the module will be called | |
32 | fat. Note that if you compile the FAT support as a module, you | |
33 | cannot compile any of the FAT-based file systems into the kernel | |
34 | -- they will have to be modules as well. | |

36 | config MSDOS_FS | |
37 | tristate "MSDOS fs support" | |

39 | help | |
40 | This allows you to mount MSDOS partitions of your hard drive (unless | |
41 | they are compressed; to access compressed MSDOS partitions under | |
42 | Linux, you can either use the DOS emulator DOSEMU, described in the | |
43 | DOSEMU-HOWTO, available from | |
44 | <http://www.tldp.org/docs.html#howto>, or try dmsdosfs in | |
45 | <ftp://ibiblio.org/pub/Linux/system/filesystems/dosfs/>. If you | |
46 | intend to use dosemu with a non-compressed MSDOS partition, say Y | |
47 | here) and MSDOS floppies. This means that file access becomes | |
48 | transparent, i.e. the MSDOS files look and behave just like all | |
49 | other Unix files. | |
50 | ||
51 | If you have Windows 95 or Windows NT installed on your MSDOS | |
52 | partitions, you should use the VFAT file system (say Y to "VFAT fs | |
53 | support" below), or you will not be able to see the long filenames | |
54 | generated by Windows 95 / Windows NT. | |
55 | ||
56 | This option will enlarge your kernel by about 7 KB. If unsure, | |
57 | answer Y. This will only work if you said Y to "DOS FAT fs support" | |
58 | as well. To compile this as a module, choose M here: the module will | |
59 | be called msdos. | |
60 | ||
61 | config VFAT_FS | |
62 | tristate "VFAT (Windows-95) fs support" | |
63 | select FAT_FS | |
64 | help | |
65 | This option provides support for normal Windows file systems with | |
66 | long filenames. That includes non-compressed FAT-based file systems | |
67 | used by Windows 95, Windows 98, Windows NT 4.0, and the Unix | |
68 | programs from the mtools package. | |
69 | ||
70 | The VFAT support enlarges your kernel by about 10 KB and it only | |
71 | works if you said Y to the "DOS FAT fs support" above. Please read | |
72 | the file <file:Documentation/filesystems/vfat.txt> for details. If | |
73 | unsure, say Y. | |
74 | ||
75 | To compile this as a module, choose M here: the module will be called | |
76 | vfat. | |

83 | This option should be set to the codepage of your FAT filesystems. | |

91 | help | |
92 | Set this to the default input/output character set you'd | |
93 | like FAT to use. It should probably match the character set | |
94 | that most of your FAT filesystems use, and can be overridden | |
95 | with the "iocharset" mount option for FAT filesystems. | |
96 | Note that "utf8" is not recommended for FAT filesystems. | |

97 | If unsure, you shouldn't set "utf8" here - select the next option |
98 | instead if you would like to use UTF-8 encoded file names by default. | |
