This is the current version of XOS as described on
the Overview page. Anyone new to XOS
should use this version. Anyone currently working with version
3.1.69 should seriously consider switching to this version. All
current devleopment is being done on this version.
The only method currently available to download and
install this version as a bootable system uses the mkxosinst program
to create an XOS boot disk on a USB "flash stick". See the
Install page for details.
(about 500KB) This is the executable for the MS Windows program
(version 1.2.0) that is used to create an XOS boot disk.
(about 18MB) This is the data file used by xosmkinst. It contains
all of the executable code and source files for XOS.
(about 1.7MB) This zip file contains the complete source for
xosmkinst.exe. It contains 3 VC++ 6 projects. The swc and zlib
projects must be built before xosmkinst is built. It may be
necessary to modify some of the search paths depending on where
on your system the VC++ 6 files are located.
The following zip files are provided for anyone who
just wants to examine the XOS code without creating a bootable disk.
Everything in these files is included in the xid file above so
it is not necessary to download any of these if you are using
the xid file.
(about 10.5MB) This file contains the xossys directory tree which
contains all of the executable code, library files, and header
(about 5.2MB) This file contains the xossrc directory tree which
contains all of the internally written XOS source code.
(about 5.2MB) This file contains the xosaux directory tree which
contains all of the source code for external packages.
Unfortunately, the XOS documentation that has been
written is seriously out of date. These two manuals describe a
version of XOS (3.2.0) which is only slighter newer than version
3.1.69. Unfortunately, we have not had the resources to update these
manuals and this situation is not likely to change very soon.
Since the basic structure of XOS has not changed and we believe
that these manuals will provide some useful information, we have
decided to make than available as-is. Please refer to the list
of differences on the Overview page
when using these manuals.
NOTE: Some versions of the Acrobat plug-in have signficant
bugs. It will often work better to right-click on the links,
save to a file, and use the external Acrobat reader to view the

(about 1.5MB) This is the XOS Programmer's Guide which describes
the XOS API.
This version of XOS is obsolete, deprecated, not
supported, etc. It is provided in case anyone really wants to
look at it. If you are seriously interested in doing anything
with XOS please use version 4.5.0.
There are two
ways to download and install version 3.1.69 of XOS. You can download
the binary and boot zip files and install XOS from these. You can
also download the source zip file if desired. Alternately, you can
download a zipped ISO image of a bootable XOS CD.
XOS can be run from this CD or it can be copied to a hard drive.
This CD also includes the complete XOS and external sources.
xos_3_1_69.zip (about 2.6MB) This Zip
