Good evening:

Thanks very much to Eric Auer and Michael Devore for all of the
suggestions!  The support has been OUTSTANDING!

OK, I have learned a bit more.  Apparently, NTFS4DOS is
slightly smarter than the documentation would have me believe.

I did some experiments with MS-DOS 6.22 and let the wizard
create the floppy disk.  It wrote just "NTFS4DOS" to autoexec.bat
with something called  I removed that from autoexec.bat
since I have NO IDEA what it is.

So, I learned that you can just run NTFS4DOS from the command
line, without any arguments, and it behaves pretty well and does
what I need (maps the NTFS partition and it stays mapped until

Under MS-DOS 6.22, newest version of UMBPCI:

Conventional Memory    640     138    501
Upper                               64         0      64

Under MS-DOS 6.22, EMM386.EXE (MS-DOS flavor)

Conventional Memory    640      226    414
Upper                               51          0      51

FreeDOS, development kernel,, sys
Newest HIMEM, Newest UMBPCI

Conventional Memory    639      141     498
Upper                                64         4       60

FreeDOS, development kernel,, sys
Newest HIMEM/EMM386

Conventional Memory    639       384    255
Upper                                64          4      60

Trying to use installhigh/loadhigh doesn't help and, in fact,
crashes MS-DOS 6.22 (error messages from FreeDOS).

There are argument differences in himem and emm386:

MSDOS: (from Datapol's documentation)


MSDOS: (based on sheer guesswork)
DEVICEHIGH=a:\emm386.exe noems

FreeDOS: (based on suggestions)
DEVICEHIGH=a:\fdos\emm386.exe x=test memcheck vds noems max=256M

Does this spark any ideas?  It looks like chasing another K of Upper
memory won't help.  It also looks like installhigh/loadhigh isn't the
way to go.  (Thanks to Eric Auer for suggesting that or I probably
wouldn't have noticed the significance of that autoexec.bat file).

Thanks again for the great support!  I appreciate it a lot.
