3. The system downloads the build image from the file server.
4. The system compares the current local build image to the downloaded build image as follows.
a If the build image versions match, the system does not try to load any image and
comes up with the Dell prompt.
00:02:55: %STKUNIT0-M:CP %BMP-5-BMP_RELEASE_HEADER_INFO:

00:02:55: %STKUNIT0-M:CP %BMP-5-BMP_RELEASE_HEADER_INFO:

b If the build images versions are different, the system stores the downloaded build
image in the local Flash and loads the build image from the Flash. This process is
repeated until the build image versions match.
The system looks for the configuration file on the file server. If the system does not
find a configuration file, the download fails. If the build image processing is
successful, BMP stops. If the build image download also fails, the current offer is
treated as invalid and BMP tries to send DISCOVER messages.
