/usr/sbin/mount -rF cdfs /dev/cdrom/c0b0t#l0 /mnt
where /mnt is the mount point directory and t# is the SCSI ID of the CD-ROM device. For example, if your CD-ROM drive is set to a SCSI ID of 5, you would specify /dev/cdrom/c0b0t5l0.
cd /mnt/arcagnts/sco5
dd if=VOL.000.000 of=/dev/install
/dev/install is the default floppy drive on your system. If you want to use a different floppy drive, specify that device instead.
