He doesn't 34respond to the address given above... 35 36This filesystem doesn't have a maintainer. 37 38What is this Driver? 39==================== 40This module implements the native filesystem of BeOS http://www.beincorporated.com/ 41for the linux 2.4.1 and later kernels. Currently it is a read-only 42implementation. 43 44Which is it, BFS or BEFS? 45========================= 46Be, Inc said, "BeOS Filesystem is officially called BFS, not BeFS". 47But Unixware Boot Filesystem is called bfs, too. And they are already in 48the kernel. Because of this naming conflict, on Linux the BeOS 49filesystem is called befs. 50 51How to Install 52============== 53step 1. Install the BeFS patch into the source code tree of linux. 54 55Apply the patchfile to your kernel source tree. 56Assuming that your kernel source is in /foo/bar/linux and the patchfile 57is called patch-befs-xxx, you would do the following: 58 59 cd /foo/bar/linux 60 patch -p1 < /path/to/patch-befs-xxx 61 62if the patching step fails (i.e. there are rejected hunks), you can try to 63figure it out yourself (it shouldn't be hard), or mail the maintainer 64(Will Dyson <will_dyson@pobox.com>) for help. 65 66step 2. Configuration & make kernel 67 68The linux kernel has many compile-time options. Most of them are beyond the 69scope of this document. I suggest the Kernel-HOWTO document as a good general 70reference on this topic. http://www.linuxdocs.org/HOWTOs/Kernel-HOWTO-4.html 71 72However, to use the BeFS module, you must enable it at configure time:: 73 74 cd /foo/bar/linux 75 make menuconfig (or xconfig) 76 77The BeFS module is not a standard part of the linux kernel, so you must first 78enable support for experimental code under the "Code maturity level" menu. 79 80Then, under the "Filesystems" menu will be an option called "BeFS 81filesystem (experimental)", or something like that. Enable that option 82(it is fine to make it a module). 83 84Save your kernel configuration and then build your kernel. 85 86step 3. Install 87 88See the kernel howto <http://www.linux.com/howto/Kernel-HOWTO.html> for 89instructions on this critical step. 90 91Using BFS 92========= 93To use the BeOS filesystem, use filesystem type 'befs'. 94 95ex:: 96 97 mount -t befs /dev/fd0 /beos 98 99Mount Options 100============= 101 102============= =========================================================== 103uid=nnn All files in the partition will be owned by user id nnn. 104gid=nnn All files in the partition will be in group nnn. 105iocharset=xxx Use xxx as the name of the NLS translation table. 106debug The driver will output debugging information to the syslog. 107============= =========================================================== 108 109How to Get Lastest Version 110========================== 111 112The latest version is currently available at: 113<http://befs-driver.sourceforge.net/> 114 115Any Known Bugs? 116=============== 117As of Jan 20, 2002: 118 119 None 120 121Special Thanks 122============== 123Dominic Giampalo ...
