  The boot order is PCMCIA or floppy -> Flash -> Disk -> Lan ->

  back to PCMCIA or floppy. Typing reboot from the command prompt will

  cycle through the boot devices. On some models, you can set the next

  boot device using the nextboot command: nextboot compact-flash | disk

  For more information, use the help command: help

  Hit [Enter] to boot immediately, or any other key for command prompt.

  Like you said, the script will run fsck, mount the appropriate slices,

  and then run mgd and start the cli. You can do this all manually if

  you want or run the script, does not matter. The script is just

  easier to remember if your not familiar with the manual method.

  : Question...

  :

  : I am wondering though about how you get to the boot prompt itself?

  :

  : Your instructions say:

  : 1) obtain console access

  : 2) power off the system and boot it up in single user mode

  : 3) type -s at the boot prompt.

  :

  : So JUNOS runs off of UNIX BSD which is what youll be accessing when

  you

  : boot the router. So you have to use -s (single user mode) and then

  you run

  : the script.

  :

  : I think the script must run the fsck and mount and starts the

  management

  : daemon

  : if my information is correct, but getting to the boot prompt is

  confusing me.

  :

  : So I am assuming that when the Juniper router reboots that

  : it will automatically boot to Multiuser mode unless you specify

  single

  : user mode (which has no password)?

  : The question is then how do you get to the boot prompt so that

  : you can specify the -s option. Does it come up automatically?

  :

  : As you can tell I do not have the luxury to test out this sequence.
