           Summary: Can't run DOS applications (without dosbox)
           Product: Wine
           Version: 1.7.20
          Hardware: x86-64
               URL: http://www.dosgamesarchive.com/download/simcity/
                OS: Linux
            Status: UNCONFIRMED

Noticed while looking at bug 7387. I'm not sure if my system is at fault or
wine, so leaving as unconfirmed for now.

austin(a)aw25 ~/oldbugs/7387 $ sha1sum simcity.zip 
1b8bd90cabb66ec3b13ed0c877bcf977b8fbf3b9  simcity.zip
austin(a)aw25 ~/oldbugs/7387 $ du -h simcity.zip 
568K    simcity.zip

Trying to run the demo in a clean 32-bit prefix:
austin(a)aw25 ~/s $ wine SIMDEMO.EXE 
winevdm: Cannot start DOS application Z:\home\austin\s\SIMDEMO.EXE
         because vm86 mode is not supported on this platform.
         You should install DOSBox.

I should have vm86 support:
austin(a)aw25 ~/s $ grep -i vm86 ~/wine-git/include/config.h
/* Define to 1 if you have the <sys/vm86.h> header file. */
#define HAVE_SYS_VM86_H 1

attached is a +winevdm,+module,+relay,+tid trace

--- Comment #1 from André H. <nerv(a)dawncrow.de> ---
thx for the log, found it:
/* enter_vm86 will fail with ENOSYS on x64 kernels */

this means you need a 32-bit kernel and Wine is right with:

vm86 mode is not supported on this platform.
You should install DOSBox.
