Program can not be run in DOS mode

Program can not be run in DOS mode

[bob olbrich]

Hello,

     I just came across Cygwin a few days ago, so I decided to try it.
Eventually, I got it to download and install successfully. However,
it does not want to boot.
    The error in the subject occurs every time I use the shortcut on
my desktop. By using the step-by-step boot in Win98, I found
that the error occurs after the following line:

     Call c:\windows\command.com /e:4096 /c c:\cygwin\cygwin.bat

   Cygwin.bat looks like:

       @echo off

       C:
       chdir \cygwin\bin

       bash --login -i

    One more command is executed (c:\windows\win.com /wx)
 and the machine reboots to Windows. Can someone with more experience
help?

Thanks,  Bob Olbrich   rjob@gulftel.com

What's invoking win.com and why?  You can't "boot" Cygwin.  You can *run*
cygwin.bat from Windows however.

Hi Bob,

what gave you the impression, the Cygwin bash is a DOS application? The
Cygwin bash uses the API and services of Windows, it is not a *replacement*
to the command.com, but just another alternative shell for Windows. You will
not succeed. No way.

Greetings,
Jorg

      I downloaded setup.exe from the cygwin page. I ran setup.exe, chose a mirror site, and
downloaded all of the contents. I ran setup again and chose to install from a local directory.
That completed with no errors. Finally, the desktop icon was produced. Have I missed
something? Are there some post-install steps to follow?

Re: Program can not be run in DOS mode

Click on the icon and that will put you at the bash prompt.  Do you know 
Unix because if you do then you will now what to do here as you are 
essentially and a shell prompt IE much like a C:\ when you go to Command 
Prompt on NT or MS-Dos prompt on Windows.  At this prompt however you use 
unix commands like:

ls -l
cd /bin

Now you can get familiar with Cygwin - but go remove the Call line you 
mentioned from your autoexec.bat file.

  I think I solved the problem! For the shortcut cygwin.pif "properties", "program",
"advanced" had MS-DOS mode checked. I unchecked this and checked "suggest MS-DOS mode
as necessary". This eliminated the attempted re-boot and put me in a window with the
$ prompt.
