Boot Agent Configuration Customization Options (Word 32h)

Word 32h is used to store the version of the boot agent that is stored in the Flash
image. When the Boot Agent loads, it can check this value to determine if any first-time
configuration needs to be performed. The agent then updates this word with its
version. Some diagnostic tools to report the version of the Boot Agent in the Flash also
read this word. This word is only valid if the PPB is set to 0b. Otherwise the contents
might be undefined.
