[comp.sys.ibm.pc] How do .DRV files work?

Can someone explain to me what a .DRV file is and how an application
program uses it to deal with many different hardware configurations?
Is it a device driver?  Is it added to the environment?  Help.

P.S.  If anyone is wondering why I have double posted this, I gave
      it the wrong distribution before.
