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 ZyWALL, 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 Firmware
and Configuration File Maintenance chapter.

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.
