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