curaga,
to be honest, I have never run dosbox, just read quite a lot about it, amongst other how it compares to dosemu, and which one is more suitable under which circumstances and for which purposes, and dosbox did never appeal to me as a replacement for dosemu.
Anyway, in the meantime I downloaded the dosemu rpm binaries, and after overcoming the biggest hurdle of extracting the rpm it seems to work quite nicely.
Still couldn't harm though having an extension I guess, but not of high priority then.
On a sidenote, I can remember having had to do a lot of trial and error to set dosemu up correctly years ago.
