I have never tried this method. When I fooll around with MS DOS or other
DOSes, I usually remove DDOS and install the new DOS from scratch. I'll see
if I can explain a few things. When using more than one DPS, you usually put
each version on it's own primary partition. My experience is that when you
do this, the other DOS (the one not being used) is hidden and you cannot
access that partition. You boot the partition you want by changing the boot
partition with fdisk.

You may be able to do this, however, I have never tried it. Be sure to back
up exverything before trying this. I would first install DRDOS. Then I
would copy the autoexec.bat ile to a file named autodos7.bat and copy the
config.sys file to dconfig.sys. I would copy the COMMAND.COM file to the
DRDOS directory. Then edit the dconfig.sys file to show the COMMAND.COM is
at d;/DRDOS/COMMAND.COM on the COMSPEC line. This will allow you to have
your DRDOS set up separately from your MS DOS. Boot the system and make sure
it boots to DOS okay. Then delete the config.sys, autoexec.bat and
command.com files from the root directory.
Now, install MS DOS 6.22xxxx whatever it is. Now your system should boot to
MS DOS. run CHKDSK /V nad make sure that MSDOS can read the drive okay (I
have not had a problem, but seems like some people have had problems if
formatted with DRDOS.) If everything is okay, then change to C:\DRDOS
directory and run LOADER. This will now make the system bootable to either
DRDOS or MSDOS. The MSDOS will use the COMMAND.COM in the root directory and
the DRDOS will use the one in the DRDOS directory. MSDOS will use the
AUTOEXEC.BAT and CONFIG.SYS files when booting. DRDOS will ignore these
files and use the DCONFIG.SYS and AUTODOS7.BAT files when booting.
As I have stated above, I have never tried this. I have no use for MSDOS and
have had no reason to try it. I may try it one of these days just for
reference purposes.
As far as having problems with DRDOS v7.0x FDISK, I have never run into a
problem with it. I have just seen several references to people having
problems with it and not recommend using it. Thus far. in response to my
message, all I have seen is a possible formatting problem, but have doubts
about that too. Someone else said they have used it on small drives and had
no problems. When I get more responces and see an actuall problem that I can
actually dupilicate myself, I am not sure there is any problem. I have used
DR/Novell/Caldera OpenDOS for many, many years and have ocassionally put
MSDOS on my computer to check out things. Even IBM DOS, RXDOS, FreeDOS, and
many other things to check them out. I do not recall re-formatting the drive
with other than DRDOS except way back when I was using MS DOS 3.3 and MSDOS
5.0.
