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.
Hm, why exactly is that necessay?

It is not _neccessary_. Try to come up with another method that gets
relocations right. I could not :-(.

(Actually, putting table at the offset 0 and short jump at beggining
of the table would probably do the trick. But that still keeps code at
offset 0 :-).

Why not just put a pointer to the start of the code in the table, and make an indirect call to it?

Where is this code?
