     to each adapter family:

         readme_xp.txt:   AccelePort 2p, 4p, 8p, and 16p.
         readme_fep5.txt: AccelePort C/X, Xem, and Xr.

     Installation documentation can be found at Digi's Web 
     site, http://www.digi.com, or at Digi's FTP server, 
     ftp://ftp.digi.com.

     When installing a beta driver on Windows XP or Server 2003,
     run the program Digiclean.cmd to move the existing INF files 
     for the adapter. This ensures that the new driver files will 
     be installed instead of the old driver files. Digiclean.cmd 
     is part of the driver software package and can be found in 
     the same directory as the new driver files.

     Note: using Digiclean.cmd is not necessary on Windows Vista.
