No, you already have this.

Steven said:

    try marking named.exe as MPUNSAFE


So, assuming you are in the directory with named.exe and markexe.exe is in 
%PATH%:

markexe MPUNSAFE named.exe <Enter>

That's how you "mark" "named.exe" as "MPUNSAFE"

If you run:

markexe /?

you'll find out lots of neat things it can do.

Verify that your marking is in effect with:

markexe DISPLAY named.exe

which should (among other things) list MPUNSAFE.

You've been doing this stuff a while, so I'm surprised this was not more 
obvious to you.

BTW, if you don't have the toolkit installed for some reason (Arca Noae does 
not distribute the toolkit with ArcaOS, as it is not part of our licensing 
agreement with IBM), you may install the toolkit from RPM (yum install 
os2tk45 or use ANPM). Note that the Netlabs RPM distribution does not 
install the toolkit to the "expected" location, but the binaries should be 
locatable.
