I think I am beginning to, you are addressing your immediate

top-down though :-)

If there are any c.l.a archives around, try and find articles
in the 1998-2000 range. There were an extremely large number
of OS design messages with very little relevence to Ada
specifically. This thread is nowhere near the extremes of the
messages in that era :-)

PS. If you decide to go further, watch out for GRUB. It has
two issues which I found presumptious when I was playing with
this stuff (toy OSes) a couple of years ago.

1) To get to 32-bit protected-mode, an initial set of gates
(interrupt, task etc) has to be established. GRUB does this.

2) The documentation (GRUB version 0.96 I think) clearly stated
that the implementors intended to implement a more "complete"
memory-manager.

Both these issues, in my opinion, should be within the kernel
space and not the bootloader.
