It is also possible to use the special switch setting 999 in the above procedure. With this setting
the IP address is still forced to 192.168.100.100, but the A500 proceeds to boot any installed
application code after the POST. However, if there is a large version incompatibility between
the embedded application and the PSI Diagnostic host, the host may not be able to communicate
to allow a new code download. The boot state, however, as accessed using the 888 setting,
should be accessible from all Diagnostic host versions.
