138 help
139 If you want to use one of the FAT-based file systems (the MS-DOS and
140 VFAT (Windows 95) file systems), then you must say Y or M here
141 to include FAT support. You will then be able to mount partitions or
142 diskettes with FAT-based file systems and transparently access the
143 files on them, i.e. MSDOS files will look and behave just like all
144 other Unix files.
145
146 This FAT support is not a file system in itself, it only provides
147 the foundation for the other file systems. You will have to say Y or
148 M to at least one of "MSDOS fs support" or "VFAT fs support" in
149 order to make use of it.
150
151 Another way to read and write MSDOS floppies and hard drive
152 partitions from within Linux (but not transparently) is with the
153 mtools ("man mtools") program suite. You don't need to say Y here in
154 order to do that.
155
156 If you need to move large files on floppies between a DOS and a
157 Linux box, say Y here, mount the floppy under Linux with an MSDOS
158 file system and use GNU tar's M option. GNU tar is a program
159 available for Unix and DOS ("man tar" or "info tar").

Linus Torvalds1da177e2005-04-16 15:20:36 -0700161 The FAT support will enlarge your kernel by about 37 KB. If unsure,

165 fat. Note that if you compile the FAT support as a module, you
166 cannot compile any of the FAT-based file systems into the kernel

269 disabled by default. To enable them, supply the option debug_msgs=1
270 at the kernel command line when booting the kernel or as an option
271 to insmod when loading the ntfs module. Once the driver is active,
272 you can enable debugging messages by doing (as root):
273 echo 1 > /proc/sys/fs/ntfs-debug
274 Replacing the "1" with "0" would disable debug messages.

289 The only supported operation is overwriting existing files, without
290 changing the file length. No file or directory creation, deletion or
291 renaming is possible. Note only non-resident files can be written to
292 so you may find that some very small files (<500 bytes or so) cannot
293 be written to.
294
295 While we cannot guarantee that it will not damage any data, we have
296 so far not received a single report where the driver would have
297 damaged someones data so we assume it is perfectly safe to use.
298
299 Note: While write support is safe in this version (a rewrite from
300 scratch of the NTFS support), it should be noted that the old NTFS
301 write support, included in Linux 2.5.10 and before (since 1997),
302 is not safe.

1178 help
1179 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
1180 used by Novell NetWare clients to talk to file servers. It is to
1181 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
1182 to mount NetWare file server volumes and to access them just like
1183 any other Unix directory. For details, please read the file
1184 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
1185 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
1186
1187 You do not have to say Y here if you want your Linux box to act as a
1188 file *server* for Novell NetWare clients.

1190 General information about how to connect Linux, Windows machines and
1191 Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

1193 To compile this as a module, choose M here: the module will be called
1194 ncpfs. Say N unless you are connected to a Novell network.

1201 help
1202 Coda is an advanced network file system, similar to NFS in that it
1203 enables you to mount file systems of a remote server and access them
1204 with regular Unix commands as if they were sitting on your hard
1205 disk. Coda has several advantages over NFS: support for
1206 disconnected operation (e.g. for laptops), read/write server
1207 replication, security model for authentication and encryption,
1208 persistent client caches and write back caching.
1209
1210 If you say Y here, your Linux box will be able to act as a Coda
1211 *client*. You will need user level code as well, both for the
1212 client and server. Servers are currently user level, i.e. they need
1213 no kernel support. Please read
1214 <file:Documentation/filesystems/coda.txt> and check out the Coda
1215 home page <http://www.coda.cs.cmu.edu/>.
1216
1217 To compile the coda client support as a module, choose M here: the
1218 module will be called coda.
