Hi!

I really need the entry point to be at offset 0, so that I can get
pointers to my data. I could not figure out how to do it any other
way. And if 0 is taken, I thought I'd put header at the end.

Why not just put the structure at 0, and put pointers in the structure to everything else you need?

segments:offsets rear its ugly head here. I need %ds to point to my
data, and the way to do it is copy it from %cs; that needs start to be
at 0.

If you can find a solution that does not need this (some
segment/offset arithmetics at beggining of wakeup?) we could use it,
but I was lost between relocations.


Let me look at it in the morning. Got a specific pointer?
