                      9: utilities are used to format/verify new drives, copy from tape to
                     10: disk or from disk to disk, and install the root

                     53: below). After each execution
                     54: the utility restarts from the beginning waiting for new arguments from
                     55: the user. To execute another utility
                     56: the boot has to be restarted.

                     70: boot device and file to boot. This is also the command used to get the
                     71: boot activate the stand alone utilities.
                     72: See Power 6 Installation Manual and Console Processor Manual for detail.
                     73: .HP 14
                     74: ls     list a directory. Asks the user for directory name of the form

                     80: on any controller. Asks the user for controller number and drive name.
                     81: The name "other" can be used for a drive which is not one of the drive

                     83: case the program
                     84: asks the user for the drive parameters. (number of heads, sectors and
                     85: cylinders). The format takes 5 to 10 minutes to complete, depending on
                     86: the drive type.

                     90: whole drive. Soft errors are reported while hard error terminates the
                     91: verify process. See the VDDC manual for status words reported by the

                     94: vdverify       read/verify a drive on a vddc controller. Same as the
                     95: verify option of the vdformat program.
                     96: .HP 14
                     97: fastcopy       a fast copy program from tape to disk or from
                     98: disk to disk. It uses a large buffer (up to 63 Kbytes) for each read/
                     99: write operation.
                    100: .HP 14
                    101: devcopy        disk/tape to disk copy program. This program uses a 1Kbytes buffer
                    102: for I/O.
