- WHAT IS THIS DRIVER?
- ==================
- This module implements the native filesystem of BeOS <http://www.be.com/>
- for the linux 2.4.1 and later kernels. Currently it is a read-only implementation.
- Which is it, BFS or BEFS?
- ================
- Be, Inc said, "BeOS Filesystem is officially called BFS, not BeFS".
- But Unixware Boot Filesystem is called bfs, too. And they are already in the
- kernel.
- Because of this nameing conflict, on Linux the BeOS filesystem is called befs.
- HOW TO INSTALL
- ==============
- step 1. Install the BeFS patch into the source code tree of linux.
- Apply the patchfile to your kernel source tree.
- Assuming that your kernel source is in /foo/bar/linux and the patchfile is called
- patch-befs-xxx, you would do the following:
- cd /foo/bar/linux
- patch -p1 < /path/to/patch-befs-xxx
- if the patching step fails (i.e. there are rejected hunks), you can try to
- figure it out yourself (it shouldn't be hard), or mail the maintainer
- (Will Dyson <will_dyson@pobox.com>) for help.
- step 2. Configuretion & make kernel
- The linux kernel has many compile-time options. Most of them are beyond the
- scope of this document. I suggest the Kernel-HOWTO document as a good general
- reference on this topic. <http://www.linux.com/howto/Kernel-HOWTO.html>
- However, to use the BeFS module, you must enable it at configure time.
- cd /foo/bar/linux
- make menuconfig (or xconfig)
- The BeFS module is not a standard part of the linux kernel, so you must first
- enable support for experimental code under the "Code maturity level" menu.
- Then, under the "Filesystems" menu will be an option called "BeFS filesystem (experimental)",
- or something like that. Enable that option (it is fine to make it a module).
- Save your kernel configuration and then build your kernel.
- step 3. Install
- See the kernel howto <http://www.linux.com/howto/Kernel-HOWTO.html> for
- instructions on this critical step.
- USING BFS
- =========
- To use the BeOS filesystem, use filesystem type 'befs'.
- ex)
- mount -t befs /dev/fd0 /beos
- MOUNT OPTIONS
- =============
- uid=nnn All files in the partition will be owned by user id nnn.
- gid=nnn All files in the partition will be in group nnn.
- iocharset=xxx Use xxx as the name of the NLS translation table.
- debug The driver will output debugging information to the syslog.
- HOW TO GET LASTEST VERSION
- ==========================
- The latest version is currently available at:
- <http://befs-driver.sourceforge.net/>
- ANY KNOWN BUGS?
- ===========
- As of Jan 20, 2002:
-
- None
- SPECIAL THANKS
