Variable
OL-11157-01
To configure the ACE to autoboot the system image identified in the boot
environment variable, use the config-register command in the Admin context
from the configuration mode and set the configuration register to 0x1.
A config-register setting of 0x1 instructs the ACE to boot the system image
identified in the BOOT environment variable and to load the startup-configuration
file stored in Flash memory. The BOOT environment variable is identified
through the boot system command to specify a list of image files on various
devices from which the ACE can boot at startup (refer to
the
ACE).
If the ACE encounters an error or if the image is not valid, it will try the second
image (if one is specified). Upon startup, the ACE loads the startup-configuration
file stored in Flash memory (nonvolatile memory) to the running-configuration
file stored in RAM (volatile memory).
