What line ? Seems you lost the context..
/ram and /use=xxxx-yyyy are options of EMM386.EXE (check output of
EMM386 /HELPDEVICE). /use forces usage of an UMB area as upper RAM
for device drivers. As said before, you should try to
/use=F000-(not more than F7FF) to map RAM over your BIOS ROM
setup code (which is only used at system boot, if ever).
F7FF as upper limit is worth a try, but might crash your
system; in this case, try a lower value (F6FF worked for me).

1B00 is a hexadecimal number giving an estimate for the size of
command.com
to the system software. Maybe the value 1B00 is just too low;
with my 7.02 Beta, SIZE=2180 works fine and gives a significant
rise in lower memory. Try SIZE=2800 and you should see a
difference with MEM /ap.
