Configuring the Boot Image/Configuration Settings
The Boot Image/Configuration pane lets you choose which image file the adaptive security appliance
will boot from, as well as the configuration file to use at startup. Choose Configuration > Device
Management > System Image/Configuration > Boot Image/Configuration.
You can specify up to four local binary image files for use as the startup image, and one image located
on a TFTP server for the device to boot from. If you specify an image located on a TFTP server, it must
be first in the list. If the device cannot reach the TFTP server to load the image, it tries to load the next
image file in the list located in flash.
If you do not specify any boot variable, the first valid image on internal flash will be chosen to boot the
system. The Boot Image/Configuration pane includes the following fields:
• Boot Order—Displays the order in which binary image files will be used to boot.
• Boot Image Location—Displays the physical location and path of the boot file.
• Boot Configuration File Path—Displays the location of the configuration file.
