Don't know about its meaning, but its "weight" (size?) is V86_TOS
bytes. "?" after `dup' mean ununitialized value(s) and, thus, this segment
may be easily not present in executable image.
My apologies to everyone, I didn't see that V86_TOS was a constant.

This is "POST Reset Flag" (see RBIL, memory.lst, Table M0021). Though,
there is not described value 00AAh.
That's what I couldn't see.
Ok, thanks to all. I knew it would be a difficult task. I was more referring to the SEQ issue mentioned by Jeremy.ASM> (6) Finally, a simple and un-intentioned question about TASM/NASM.

This is a lot of work, especially because NASM language is not
completely equal (and much more dumb) and error prone.
It's a pitty that EMM (as ATAPI) can't be compiled with free (-ly downloadable) compilers, but anyway I would think twice before trying this.
