reading the DIO device ID at select code 7, but rather hard-wire the ID
to the IHPIB ID. This prevents us reading what might look like a valid
ID to another device when IHPIB is present. (IHPIB doesn't always return
a correct device ID, grumble.)
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.
