Also, the SCSI host ID reported by cat /proc/drivers/nvram (also 7, in my case) TOS reports the SCSI host ID during boot (when scannig for bootable disks) IIRC. There may be some control panel to view the NVRAM settings as well (stuff like default video mode was accessible from the CT60 control panel so the SCSI host ID might be there as well).
