e.g. Eric implemented it as 'RAM' = 'I=', and 'ROM=' = 'X=', and
wondered why I didn't accept it (because it's wrong)
As I said: as soon as someone finds out what that's supposed to do _EXACTLY_, ...
=== ROM=mmm-nnn
So it seems I was right after all: not that it says much, but it's exactly what I described:

No bigdeal. Would have surprised me if it ran QBASIC NIBBLES and won't let you continue until you win the game. ;-)
=== RAM
EMM386.EXE NOEMS => UMBs
EMM386.EXE RAM => UMBs + PageFrame
default: RAM
ALMOST EXACTLY:
=== RAM=mmm-nnn
Explained here (not fully): http://support.microsoft.com/default.aspx?scid=kb;en-us;74212
There's a range of memory that is searched with the search algorythm proposed there. The range is fixed C000-DFFF, unless overriden (presumably) with the RAM= parameter.
You can also directly INCLUDE other areas with the I= forces to include these areas (with no need to be checked by the algorythm). The I= switch on EMM386.EXE has a higher order of precedence than the search algorithm.
And above that all, areas under the X= flag are unconditionally EXCLUDED.
then let me rephrase because I didn't explain myself well.some others like Win 3.11 compatThere is probably a patent to prevent us of it anyway :(
should probably be fixed before we call it FreeDOS 1.0 ...

There's a technote about Win 3.1 compatibility, and why this probably will never happen, so I don't repeat it here.
What I meant is: there are TECHNICAL (not LEGAL) problems by which we don't have it.
And by technical I mean noone set to do it (of course, there are older threads and technotes and that all).
