a shell is not to be mistaken for an operating system. sure, you could 
write an alternative CLI for DOS, but that doesn't hide DOS itself. it's 
still there, supporting your CLI. if you want to write a real OS, you 
can't depend on interrupts to back you up. you have to code everything 
yourself: basic drivers, file system(unless you use one that already 
exists), kernel(unless you borrow or modify someone else's), etc. I'm 
not sure if it would be possible with DOS or Windows, but as long as you 
don't use any of the OS' standard C functions and just write your own, 
it works at least with ELF(go to www.gaztek.org and download the GazOS 
source. it's not the best OS, considering the "commands" are built right 
into the kernel :)
