Configuring for the DEC UNIX Environment

Digital UNIX Version 4.0 and later
With Version 4.0 of their UNIX operating system, DEC
introduced a new method of configuring the CAM SCSI
Driver. Modify the file /etc/ddr.dbase as follows:
1. Locate the Database entry for the DEC TLZ07 DAT Drive
2. Copy this entry and paste it later in the file, taking care to
maintain the file syntax.
3. Modify the new entry as shown below. Modified sections
are shown in bold. See the beginning of this chapter for
