Someone wrote about all this earlier, but I believe the basic idea is this:

Up to a 4Mb code segment, and a ?Mb data segment.  The important thing about
(1) is that it allows the code segment to grow past the 640K.  It probably
does this with soem type of built in swapping??  And this method is not usable
for the data segment, or at least not for dynamic allocation.

Just my guess, and I hope it's accurate so I don't get flamed to death :-)
