Appendix C
Boot Commands
The BootModule AT commands execute from within the router’s bootup software, when debug mode is
selected before the main router firmware (ZyNOS) is started. When you start up your Prestige, you are
given a choice to go into debug mode by pressing a key at the prompt shown in the following screen. In
debug mode you have access to a series of boot module commands, for example
ATUR
(for uploading
firmware) and
ATLC
(for uploading the configuration file). These are already discussed in the
Transferring Files
chapter.

ATHE
to view all available Prestige boot module commands as shown in the next screen.
ATBAx
allows you to change the console port speed. The x denotes the number preceding the colon to give the
console port speed following the colon in the list of numbers that follows; e.g.,
ATBA3
will give a console
port speed of 9.6 Kbps.
ATSE
displays the seed that is used to generate a password to turn on the debug
flag in the firmware. The
ATSH
command shows product related information such as boot module
version, vendor name, product model, RAS code revision, etc.
ATGO
allows you to continue booting the
system. Most other commands aid in advanced troubleshooting and should only be used by qualified
engineers.
