ISOFS is an installable file system for OS/2 to access ISO rawfiles suitable for burning on CD. It allows transparent access to the contents of the raw file. Currently only Joliet filenames are supported but this may change in the future.
This file system is based on the sources of AEFS a cryptographic file system written by Eelco Dolstra. See below for further information.
This software requires the EMX runtime fix 3. It can be downloaded from: ftp://ftp.leo.org/pub/comp/os/os2/leo/gnu/emx+gcc/emxrt.zip.
You need WarpIn 0.9.4 or above to install this filesystem driver or the sources. Get it from
http://warpin.netlabs.org
or
http://www2.rz.hu-berlin.de/~h0444vnd/os2.htm Note: This address may not be valid in the future!
Unzip the zip-file to any place on your hard disk. Start WarpIn with the installation package by doubleclicking on isofs_Vx-x-x.wpi. You may select to install only the driver, the sources or both.
During driver installation WarpIn adds the following lines to your CONFIG.SYS:
A folder will be created on your desktop containing the documentation and objects to mount and unmount ISO files.IFS=<install-path>\stubfsd.ifs ISOFS RUN=<install-path>\isofsdmn.exe
The first line loads the FSD (file system driver), which is really a stub that passes requests to the daemon, which is started in the second line and does the real work. You may also want to add the bin-dir to the PATH environment variable, but that's merely a convenience.
Use WarpIn to deinstall the filesystem.
NOTE: Currently WarpIn corrupts your CONFIG.SYS while trying to remove the inserted statements. Deselect all config.sys entries in the Undo configuration listbox to make sure your system will remain bootable. Remove the entries in question by hand!
To access an ISO file as a volume, you must attach (`mount') it to a drive letter. This can be done by typing
The file 'filename' may be accessed now as drive X:. Copy, extract or view files contained in the image as if they were on your harddisk.mntisofs X: <drive>:\<path>\<filename>
When you are done using the volume, you can type
to detach it.umntiso X:
All programs use the GNU getopt syntax. They all support the following options:
The isofsdmn program is the file system daemon. The syntax is:
isofsdmn option*
It is typically started in CONFIG.SYS by a RUN statement (not a CALL statement) or from a script using the detach command.
The options are:
The mntisofs program attaches an ISO file to a drive letter. The syntax is:
mntisofs option* drive-letter: path
The options are:
Examples:
mntisofs --jcharset cp850 X: c:\directory\isoimage.raw
mntisofs y: c:\directory\another_isoimage.raw
mntisofs --jcharset cp850 z: c:\directory\another_isoimage.raw
You may access all these mounted drives in parallel.
The umntaefs program detaches an ISO file from a drive letter. The syntax is:
umntiso option* drive-letter:
The options are:
This release is a developer release which may contain bugs. Don't expect it to be rock solid.
The makefiles require GNU make.
To build the FSD (stubfsd.ifs) you need Microsoft C 6.00. This compiler can be downloaded from the IBM Developer Connection Device Driver Kit for OS/2 site at http://service.boulder.ibm.com/ddk. You also need the FSD helper library and header file, which is included in the FSD toolkit: ftp://ftp.leo.org/pub/comp/os/os2/leo/devtools/doc/ifsinf.zip.
To build the daemon and the support programs you need gcc or pgcc, available from various locations.
In general it isn't absolutely necessary to rebuild the FSD. In fact I took the precompiled FSD from the AEFS package and rewrote only the daemon.

This file system is based on AEFS a cryptographic file system written by Eelco Dolstra <edolstra@students.cs.uu.nl>. Without that work ISOFS wouldn't have been possible! It only took me a few days to get the first version run. Thanks.
The charset conversion was taken from the cdrecord package by J. Schilling.
