Run legacy DOS applications in Linux

I use Linux as my personal computing OS and it does pretty much everything I need, is stable, relatively secure, and free. However there are times when I could really use a DOS box to run some ancient DOS based program that doesn't have a Linux equivalent. This isn't a problem for Windows users who can just open a command prompt window. And it's not a problem for Linux users either, with dosemu an open source DOS emulator/virtual machine. 

For Ubuntu/Debian dosemu is intalled simply with:

apt-get install dosemu

A specific directory becomes your "C:" and you can run all those old DOS programs. I have to say that seeing autoexec.bat and config.sys in my C:\ made me a little nostalgic for the old days. The feeling passed quickly though.
