I remember I once disassembled the boot-sector. It was all pretty clear
what it did (It's put into address &Hc000 and executed from, if I
remember right, &Hc01e), except for one thing. When it starts, it saves
the data that is present in DE and A registers. DE is some kind of
address, that is called to if MSXDOS.SYS is not found or something. Does
anybody know what the exact meaning of this data is? It might be useful
when writing a program in the boot-sector that needs to go to basic
afterward, like a menu where you can choose which file you want to
execute, or something.
