DR DOS most likely reclaims portions of memory between 640KB and 1MB that
are not actually in use. While that entire portion is "reserved" only
a small portion of it is actually used in most systems. There are MS DOS
add ons that does the same thing. QRAM, 386Max, etc. are all memory 
managers that reclaim this memory space. Some also move TSRs and
network drivers to EMS freeing up the lower 640KB for applications 
that can only run in low memory.
