that's impossible.

masking it off as you do is fine.

i'd expect so, although nm on the executable will show you.

the deeper problem is that (as i understand it) you're entering the code
in real mode, which is of course quite unreal.  in that case you'll
need to do what 9load does in l.s (using x16.h) to write the real mode
code, because 8a/8l isn't very good at 16-bit code
(though 8l could make it easier, with some as yet unquantified amount of work).

i'd put it what's needed a separate l16.s prefix, using x16.h
to write it (most of what you need is at the start of 9load's l.s),
then link l16.$O in front of a slightly modified l.$O and enter the kernel at l16.$O's start.
