3.2.2 Specifying a Boot ROM File for the Next Device Boot

A Boot ROM file is an application file used to boot the device. When multiple Boot ROM
files are available on the storage device, you can specify a file for the next device boot
by executing the following command.
Follow these steps to specify a file for the next device boot:
Specify a Boot ROM file
on a card
Caution:
The file for the next device boot must be saved under the root directory of the device
(for a device supporting storage device partition, the file must be saved on the first
partition). You can copy or move a file to change the path of it to the root directory.

3.2.3 Upgrading Boot ROM

During the operation of the device, you can use Boot ROM in the storage device to
upgrade those that are running on the device.
Since the Boot ROM programs of switching and routing processing units (SRPUs) and
line processing units (LPUs) vary with devices, users are easily confused to make
serious mistakes when upgrading Boot ROM. After the validity check function is
enabled, the device will strictly check the Boot ROM upgrade files for correctness and
version configuration information to ensure a successful upgrade. You are
recommended to enable the validity check function before upgrading Boot ROM.
Follow these steps to upgrade Boot ROM:
