Hi all, I'm reposting the below message, with the original

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.
