This does not sound quite right. It looks like you have 1MB of 
convention memory divided into the usual 640K of available
and 384K of reserved memory and not 640K of conventional and 384K of
extended memory. I do not believe you can add extended memory
in anything less than 512KB chunks. The 384KB in the 640KB to
1MB address range is reserved but is still part of the conventional memory
space. Because much of it is not in actual use, it is possible
to "high load" TSRs and drivers into this area. Because this
memory is still conventional memory, nothing special is
really needed other knowing what slots are not used. Try QRAM or Move'EM.
They are designed to do this with 286 machine with or without the
C&T NEAT chipset.
