Gera, no need for excuses. :) SqueakNOS is a great thing by itself, showing how
it easy to control the hardware using high level language (instead of
assembly), and its not some kind of black voodoo except if you don't
have any documentation.

P.S. I remember the QNX floppy demo disks, which is a bootable
diskette containing
the OS + net & graphics drivers + browser. So, basically you can boot
PC with it and it detects your network card (if you're lucky
and got right vendor), and then you can go & browse the internet.
All of it fits into 1.44 Mb diskette.
So, i don't think that making networking or IDE i/o is hard thing.
Just give it a time.
