when i remove -O from my Makefile the kernel grew bigger, and crossed
0xb000, so i changed it accordingly, and that didn't work.
so i guess there is 16k limitation for kernel and user program.

too bad, but there's not much to work on that either.

that's what i've been doing right now. currently, legos uses conio
which i've used long time ago. so i work on interface like linux has.
like using open() + write() instead of cputs().
right now, i don't have open(), that's because i have to write code
for virtual filesystem first.
i haven't investigate deeper on legos, i'm still figuring out how
to do fork(). what do you think?
i also don't understand why some functions (like cls()) are in the
kernel instead of the libc?
i'll send you diff if you like.
