At a first glance it looks quite good. However I can't see whether it
can handle ELF format kernels correctly (my mini kernel relies on that,
because it is basically linked to an ELF executable). It doesn't have
to. We can still define our own a.out type format, meaning a simple
memory image that only needs to be copied. I don't know how much space
is left in the boot block but the old GazOS boot block was able to load
basically the same ELF binary format Multiboot can handle. If you want
to, you can try to find your way through these sources and squezze the
same functionality into the new boot sector. To tell you the truth I
don't think this can be done because 512 bytes is simply too small for
this lot of features.

In case of questions I'd say it's better to ask and answer them directly
on the list. Anyway your working speed is really high, Wael. I would
certainly have needed weeks for that code.

Armin, Isaac: I'm a little bit confused because there hasn't been a
reaction from you yet concerning device drivers. Do you have problems
with my mini kernel? Or haven't you done anything (I don't have trouble
with that, really :-))? Or do you work silently on and on without anyone
knowing about it? Please tell me. I'd really like to know so that we
don't happen to lose oversight on this project.

So, fellows, I'll return to this list next saturday or sunday. I'll see
you then.

Bye,
Gregor
