I did say "full memory" didn't I?  The 386+ processors are
capable of addressing up to 4G.  :o)

Seriously, yes, I did make a mistake, but there was enough info
there for anyone to figure it out.  I think the proper number
should be:
BX=0010
CX=0000

This would be 0x00100000 when put together which is 64k * 16 ==
1Meg.  I think it should work as intended.  Again: untested
though.
