after the ExtendedWrite command I get the error message from the
dpmi_int13 call (BIOS) returning 0x01 ERR_BAD_COMMAND in AH.
it is possible the memory is not set up correctly.  I think I ran into
that bug once before, but I thought I fixed that with the 2 calls to
dosmemput, dosmemget.

Calls to ExtendedRead do not seem to fail however, when I use it to
get partition information.
the code almost looks exactly the same.
