 The MACHINE computers do not generally need any specific preparation.

+You might want to check that the console ``path'' in the PDC firmware
+points to the device you plan to use, and change it if necessary. Most
+models will allow to select console path from BOOT_ADMIN> prompt. To get
+to the prompt -- terminate the autoboot process and if prompted so select
+"Enter Boot Administration mode."
 
-dnl need to provide more details on how to do so! c'n'p boot(8)
+To select first serial port as console type:
+
+	BOOT_ADMIN> path console rs232_a.9600.8.none
+
+or to select graphics as console:
+
+	BOOT_ADMIN> path console graphics
+	BOOT_ADMIN> path keyboard hil
+or
+	BOOT_ADMIN> path console graphics
+	BOOT_ADMIN> path keyboard ps2
+
+On some models, such as 712, PDC firmware does not allow changing the
+console path. In this case boot into the boot> prompt (assuming booting
+from bootp/tftp or otherwise substitute your boot device for lan):
+
+	BOOT_ADMIN> boot lan isl
+
+and then at the boot> prompt:
+
+	boot> machine console rs232.9600.8.none
+
+WARNING!
+Make sure you have typed the console path correctly or 712 can
+go comatose and will require a special "dagger" board to be revived.
+
+After changing the console path machine has to be power cycled
+for changes to take effect.
+
+In most case the primary boot device path is already set to the right
+value. In those cases it has to be changed use:
+
+	BOOT_ADMIN> search
+
+to display the list of all bootable devices and then:
+
+	BOOT_ADMIN> path primary SCSI.TARGET.LUN
+
+Substitute FWSCSI or SESCSI for SCSI if it is displayed so in the path list
+above and use TARGET and LUN of the device listed or just simply copy
+over the string.
+
+Also consult the boot(8) page for more information on boot commands.
