Try this:
http://dosemu.sourceforge.net/stable/
Look at section 'Binaries'
Read the 'README.bindist; this tells you to download
both:
dosemu-1.0.2.1.bin.tgz and
dosemu-freedos-b8p-bin.tgz
follow the install instructions.
If you want, don't create a 'mydos' directory,
just unpack the two .tgz files (they're actually .gz)
in your $HOME directory. You should then have a
dosemu/ which contains the indicated structure.
cd to dosemu and run the script (./dosemu) - you're
running dosemu in console mode. Do a 'dir' at the
C:\ prompt; you should get a directory structure that
looks exactly like what you see in /$HOME/dosemu/freedos.
Copy any programs you wish to run into the /freedos
directory. For instance, I run quicken in dosemu. I created
a directory /$HOME/dosemu/freedos/quicken and copied
all quicken files into it. When I'm in dosemu at the C:\
prompt I just issue quicken/q and it runs fine.
Any problems with scattered/garbled screen, change
console resolution to 640x480 in lilo.conf. For quicken,
best also to use "ibm" character set in
/dosemu/conf/dosemu.conf.
Hope that helps!
