            Bug ID: 214670
           Summary: MCS9900-based parallel port card unsupported
           Product: Base System
           Version: 11.0-RELEASE
          Hardware: Any
                OS: Any
            Status: New

         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: fuz@fuz.su

It seems that due to an oversight, parallel port cards with the MCS9900 chi=
pset
are not supported by the FreeBSD kernel. After adding the following patch a=
nd
adding appropriate device hints, the card is supported and works fine:

 };

Please add this patch to the FreeBSD kernel so the card is supported
out-of-the-box.
