1 1.1 jdolecek Running unixfs 2 1.1 jdolecek -------------- 3 1.1 jdolecek 4 1.1 jdolecek NOTE: This version allows writes only to files/dirs with 5 1.1 jdolecek world write permission. 6 1.1 jdolecek 7 1.1 jdolecek This directory contains all the files for unixfs. 8 1.1 jdolecek 9 1.1 jdolecek unixfs_res unixfs module 10 1.1 jdolecek Killunixfs kills the unixfs module 11 1.1 jdolecek OpenRoot opens a filer window on the mounted filesystem 12 1.1 jdolecek Howto this file. 13 1.1 jdolecek mountufs utility to mount partition 14 1.1 jdolecek 15 1.1 jdolecek There are also several obey files containing commands to mount various 16 1.1 jdolecek FFS partitions e.g. 17 1.1 jdolecek 18 1.1 jdolecek wd0a - first IDE disc partition A (typically /) 19 1.1 jdolecek wd0e - first IDE disc partition E (typically /usr) 20 1.1 jdolecek 21 1.1 jdolecek These obey files use the mountufs utility. Depending on what controller 22 1.1 jdolecek your IDE discs are attached to you may need to edit these files. 23 1.1 jdolecek 24 1.1 jdolecek Once a partition has been mounted the obey file OpenRoot can be 25 1.1 jdolecek use to open a filer window on the mounted partition. 26 1.1 jdolecek 27 1.1 jdolecek To remove unixfs run the Killunixfs obey file. 28 1.1 jdolecek 29 1.1 jdolecek The mountufs utility 30 1.1 jdolecek -------------------- 31 1.1 jdolecek 32 1.1 jdolecek The mountufs utility simplifies the mounting of a harddisc partition 33 1.1 jdolecek via unixfs. mountufs takes two arguments, the RISCOS filesystem and 34 1.1 jdolecek the device e.g. 35 1.1 jdolecek 36 1.1 jdolecek mountufs ADFS wd0a 37 1.1 jdolecek 38 1.1 jdolecek The mountufs command will lookup the SWI base for the specified 39 1.1 jdolecek filesystem and will use the unit number and partition from the 40 1.1 jdolecek device to formulate the correct combined SWI for the unixfs_mount 41 1.1 jdolecek command. 42 1.1 jdolecek 43 1.1 jdolecek The unixfs_mount command 44 1.1 jdolecek ------------------------ 45 1.1 jdolecek 46 1.1 jdolecek A partition is mounted using the command unixfs_mount xxxxx where 47 1.1 jdolecek xxxxx is the combined SWI, drive and partition number in hex 48 1.1 jdolecek This number can be calculated as follows 49 1.1 jdolecek 50 1.1 jdolecek SWI base + (drive * 8) + partition 51 1.1 jdolecek 52 1.1 jdolecek For example partition e on the first IDE disc on the internal IDE 53 1.1 jdolecek controller (ADFS::4) would be 54 1.1 jdolecek 55 1.1 jdolecek 40240 + (4 * 8) + 4 = 40264 56 1.1 jdolecek 57 1.1 jdolecek 58 1.1 jdolecek SWI bases 59 1.1 jdolecek 60 1.1 jdolecek 40240 ADFS (Acorn) 61 1.1 jdolecek 41FC0 IDEFS (ICS) 62 1.1 jdolecek 40980 SCSIFS (Various) 63 1.1 jdolecek 4BBC0 ATAFS (Yellowstone) 64
