cat6k msfc2 boot procedure details?

Good morning,

I try to understand the boot process of a msfc2 in cat6500 in
hybrid mode. After reading the appropriate docs at CCO and some
practise, I understand how to boot it and mostly (*sigh*) it
works.

Asking these detailed questions to ppl also administrating
cat6k revealed a deep lack of knowledge ;-(

Can anyone enlighten me/us?
