-	tristate "ICN 2B and 4B support"
-	depends on ISA
-	help
-	  This enables support for two kinds of ISDN-cards made by a German
-	  company called ICN.  2B is the standard version for a single ISDN
-	  line with two B-channels, 4B supports two ISDN lines.  For running
-	  this card, additional firmware is necessary, which has to be
-	  downloaded into the card using a utility which is distributed
-	  separately.  See <file:Documentation/isdn/README> and
-	  <file:Documentation/isdn/README.icn> for more
-	  information.
