Actually, FDAPM should be loaded in the :DOSHIGH section of
FDAUTO.BAT. I didn't type the "LH" command before it, in my example,
but this is what's in the default FDAUTO.BAT file:


:DOSHIGH

lh fdapm APMDOS
lh ctmouse
REM lh share

if not exist %DOSDIR%\BIN\DOSLFN.COM goto NOLFN
lh %DOSDIR%\BIN\DOSLFN.COM
REM - Add other stuff here once LFN is loaded..



If you modified your FDAUTO.BAT, you should check that FDAPM is
loaded. (Note: the slash in the FDAPM command line option is optional
.. that's the same as FDAPM /APMDOS or FDAPM APMDOS)
