MSC 5.1 will not generate 386 instructions under any circumstances, not
automatically, not today, not tomorrow, not next year, not ever.  MASM 5.1
will generate some of the 386 instructions, but not all.  You have to
get somebodies (Phar Lap is an example) 386 compiler and DOS extender.


Chewey, get us outta here!
