I dunno how much u have thought about this project  and how far.. but u will have
to use a bit of assembly language for sure.. cant escape. Even I tried an op sys
completely in C.. but ended up using a lot of ASM, so give it a thought. How
will u go with boot process? and rest of the part in java! seems novel coz of
speed of java  based progs. give it a thot too.

thanks for your comments. Well, I am absolutely aware of using asm in kernel
operations. Yet, the basic parts of the system  will be written  in C++ and asm -
I use the lcc32 compiler which can generate asm. files from existing C/C++ files
- but I actually only wanted  to build the GUI with Java so the asm parts will be
very small and short.

In fact, I planned to build to two types of systems: one that would run as a
subsystem on existing ops like Windows and Unix and which would be installed in
the corresponding Java paths of the system. The booting process would look like
starting a normal application, for example typing "core.exe" in Windows "start"
and then take over the system control.
The other version would be a small kernel, which does only the bare minimum of
tasks, like sys controll, memory management, and so on.

hmm... that seems the good  idea, especially the second option wud be a great
experience. I mean, the feelin that evrything running on ur comp is ur code
completely is nice one to have.

if you are still interested you may join the_core_project. This is a yahoo user
group which can be found in yahoogroups->computers&internet->operating systems.

Right now, there are two members, me and Karthik, a cool guy from India who
immediately joined with me. You can also check out the Core OS homepage which is
so far listed at my geocities server.

Why don't you just use the linux kernel and write a java  based solid
user interface  instead?

Free from X windows system, optimized for desktop use. Different ideas.
Not originated from CDE ( xfce ) or windows ( kde, gnome ).
Something unique and also usefull...

cool response but I want to write an operating  system without too much of
console operations and which is eays-to-use and which comes with an
self-explainging desktop surface.

I don't have anything against the Linux community, there are some cool guys and
the work they do is absolutely great, but I think Linux would be even greater
for many users, especially newbies, if they would not need to worry about
hardware settings, kernel hacking, console keying etc.

Bye the way, if you have some free  time and experience with the Java Swing API -
it would also be a benefit if you have some C kernel programming  experience -
and feel free to join the_core_project which is a yahoogroup listed under
groups->computers&internet->operating systms.

I am the moderator of this group  and any queris or suggestions  may be sent to
me.
