SCSI disk devices are numbered sequentially, ordered by SCSI address. So in your case, sd0 - SCSI address 1 - internal 100M sd1 - SCSI address 2 - CDROM sd2 - SCSI address 4 - external 400M The boot command would be bsd(2,0,0)sdmach rootdev=sd2 You need to pass the rootdev=sd2 specificiation to have the kernel use the disk you booted from (sd2) rather than sd0 as the root file system. For more information, see page 145 of the release 2.x "Network and System Administration" manual. louie
