A lot of this source code is nasty.  Much of it is a bit short on comments, many modules have incomplete functionality, and in general the code could be cleaned up and optimized a ton.  I apologize for the current state of the code, and offer this as an excuse -- all of this stuff was written over the course of a semester, in order to demonstrate the usefullness and plausibility of a stream-based operating system.  So now that we've got the base down, let's work on making it fully functional!

        First, the standard explanation: SOBS was developed with gcc/nasm under DOS.  Therefore, the bootloader is a DOS executable.  This does not mean SOBS is reliant on DOS to run!  Developing under DOS was quicker than developing under Linux because the system could be compiled and tested without dumping the image to a disk and rebooting.
        These archives contain the programs you will need to load and boot a SOBS system, as well as some of the files needed to write SOBS objects.  The contents are:
 
omdos -- This program looks at afis.dir and objects.boot, loads the rdoff modules into ram and spawns pmjmp.  Use omdos to boot the system.
pmjmp -- Flops into protected mode and jumps into the SOBS system.
atn -- at&t to nasm syntax translator.

To compile C programs to rdoff objects, you will also need djgpp and nasm.  The commands to compile are:

        gcc -S test.c
        atn test.s test.atn
        nasm -f oldrdf -o test.rdf test.atn

Proof-of-Concept SOBS Code

        These files are the ones presented in the SOBS: A Stream-Based Operating System document, and form a SOBS system which was used to demonstrate the bridge object by transparently using a remote filesystem.
        The archives contain the following objects:
omboot
sys386
objctrl
debug
mem
vfsm
timer
tasker
keyboard
printer2
video
bridge2
dshell
