   Hi all, I'm reposting the below message, with the original   
   author's permission, because I think it may be helpful to many   
   sysops...

   PKZIP and dosemu don't play very well, especially if you are using a 64bit   
   linux os.   
      
   There is a way to disable DPMI (which causes the issue) via command line,    
   by adding -) to the command line, but that really doesn't help if the zip   
   and unzip routines are hardcoded into software, like interlord.   
      
   Alas, after a shit load of research I have found a work around.   
      
   First you will need pkzip 2.04g (google for pkz204g.exe or ask me to drop it   
   in your inbound).   
      
   Create a directory via dosemu to house pkzip and pkunzip (I created one in my   
   doors dir called pkzip).   
      
   Copy and run pkz204g.exe, it should uncompress all the PK stuff into   
   doors/pkzip.   
      
   Create a file in your pkzip dir called pkzip.cfg and add the following to   
   that file:   
      
   DPMI=Disabled   
      
   Next you need to set the path for your pkzip folder and disable dpmi for   
   pkunzip via your autoexec.bat. Edit autoexec.bat and add the following to   
   your path statement:   
      
   d:\doors\pkzip (where ever your created your pkzip folder)   
      
   so my path statement looks like this now:   
      
   path z:\bin;z:\gnu;z:\dosemu;d:\doors\pkzip   
      
   you also need to add the following to your autoexec.bat file right after your   
   last lredir statement:   
      
   SET PKUNZIP=-)   
      
   Now exit out of dosemu and head back into it so that your new autoexec.bat   
   takes effect.   
      
   As to why PKZIP uses a cfg file and PKUNZIP requires a variable set is beyond   
   me, why not use either or for both. Then again, we are talking about the   
   90's here/   
      
   You should now be able to run pkzip.exe and pkunzip.exe from any directory   
   without getting the dreaded DPMI error.   
      
   If you have any questions, there is a huge discussion on SciNet in the   
   gaming echo about beating dosemu into submission when it comes to running   
   old dos door games in linux.
