| 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 naming 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. Configuration & 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. |
