Understanding the boot.sys File

Understanding the boot.sys File
The system uses the boot.sys file to store the prioritized boot stack parameters and file groups the system uses
during startup. Modify this file only through system CLI commands and not through external means. Boot
parameters contain information the system needs to locate the operating system image file, including:
• bootmode: This setting is typically configured to normal, and identifies how the system starts.
• boot stack information: The boot stack is made up of prioritized file group entries that designate the
When a system is started for the first time, the boot.sys file is configured to use the normal boot mode and
load the operating system software image from the /flash directory.
There is no CLI configuration file contained on the local file system. This causes the system to automatically
start its CLI-based Quick Setup Wizard upon the first successful boot. Refer to Getting Started for more
information on using the Quick Setup Wizard.

commands described in this section in the Exec Mode. Unless otherwise specified, you must have security
administrator or administrator privileges to execute these commands.

File System Management Commands
