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 Matthias ------------------------------------------------------------ Matthias Paul eMail: Web: http://www.rhrz.uni-bonn.de/~uzs180/mpdokeng.html
