I have heard about this problem from some users of the FreeDOS VirtualBox images at
https://www.lazybrowndog.net/freedos/virtualbox/ \
<https://www.lazybrowndog.net/freedos/virtualbox/>
As far as I found out, "Bad or missing command interpreter" doesn't necessarily mean \
COMMAND.COM doesn't exist. It can also mean it can't be loaded. This seems to be an \
issue of JEMMEX on some machines.
You could experiment with JEMMEX settings. Others here know a lot more about that and \
perhaps have the time to help you.
Another possibility: If you use FreeDOS for non-commercial purposes, it would be \
legal to use the memory manager of Calderas DR-DOS instead. The full DR-DOS can be \
found here ftp://ftp.uni-bayreuth.de/pub/pc/caldera \
<ftp://ftp.uni-bayreuth.de/pub/pc/caldera> with all the necessary notes and licensing \
information. Please read it. For your convenience the driver alone can be downloaded \
here: https://www.lazybrowndog.net/freedos/dremm386.zip \
<https://www.lazybrowndog.net/freedos/dremm386.zip>.
Unzip it to a folder like C:\UTIL\DRDOS.
Look for a line similar to this one in C:\FDCONFIG.SYS:
15678?DEVICE=C:\FDOS\BIN\JEMMEX.EXE NOEMS X=TEST I=TEST NOVME NOINVLPG
and replace it by this one
15678?DEVICE=C:\UTIL\DRDOS\DREMM386.EXE NOEMS EXCLUDE=D000-D7FF
And in C:\AUTOEXEC.BAT after the following line
IF „%config%"==„4" goto end
add this line:
C:\UTIL\DRDOS\DREMM386.EXE PIC=ON
Please give some feedback if this works for you.
Note: DR-DOS EMM386 doesn't have all the features of JEMMEX so you need to test if \
your programs work with this driver. Try also different settings to get more free \
memory. I know that this is not a perfect solution.
