This is the only reason I can see why it doesn t work. If you are running Windows95, the C:\COMMAND.COM command processor is probably not
OpenDOS , but Windows. Though usually invalid command processors will
just display "Wrong DOS version" and return to the prompt (in this case to
IBMBIO.COM s internal prompt emulation), the Windows95 command processor
is an exception of the rule. Attempting to run it from a different DOS than
Windows95 via SHELL=, it will just crash instead of returning. I recommend
to put the OpenDOS command processor in the OpenDOS directory (it should
be there already) and change the directive to

SHELL=c:\opendos\command.com c:\opendos /E:384 /P:autodos7.bat

BTW, referencing to the command processor in the root directory is dangerous
if you don t have boot disks at hands. For convenience of game players, the
CONFIG.SYS parsing has changed a little: Even in F5 mode the SHELL=
directive will be parsed always. So if you are referencing to the wrong command
processor, that is Windows95 COMMAND.COM, your system will hang without
a change to bypass this directive. To avoid this, at least the last physical
SHELL= directive in CONFIG.SYS must point to a valid command processor
for OpenDOS (if you like, you can put this "emergency" SHELL= even in a
dead section of CONFIG.SYS, which will normally be bypasssed, e.g.

 ... 
 GOTO end
 SHELL=c:\opendos\command.com c:\opendos /E:384 /P:autodos7.bat
 :end
