The super-scsi device is only needed (as an alias for the entire bus) if no other SCSI device has been available at boot time. As soon as at least one device came up at boot time, you can do scsi -f /dev/rsd0.ctl -r ^^^^ use whatever device is actually already available This used to hang the entire machine in older systems, but recent 2.2-current's seem to work (at least with an AHA2940 that never worked with -r before). I think Justin's SCSI branch cleans up allot in this area. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
