cam(4) gives examples of how you can do this by using device hints in loader.conf(5) or device.hints(5). Another example: http://lists.freebsd.org/pipermail/freebsd-fs/2011-March/011036.html You may need the workaround from: http://svn.freebsd.org/changeset/base/227635 for some problematic BIOS. I'm not sure if this is what you meant by "hints which aren't really solutions", but they seem to be a practical method for fixing device names with ahci(4). b. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
