We're about 75% there. SCSI and HP-IB are not yet supported in a new config kernel; some autoconfiguration hackery has to be done there, yet. These changes are enough to network boot a diskless kernel. New config glue is enabled with the "NEWCONFIG" kernel option. If that option is not present, an old config kernel will be built. Any kernel configured with config(8) will automatically pick up the NEWCONFIG option from std.hp300.
