In general, a good way to find things is to search for the value in the dump of a camera where the value is known, and then look for recognizable landmarks nearby.

In this case, look for the strings "StartDiskBoot" and "not executable". Both are referenced by a function which calls another function that decodes the diskboot. The "not executable" string is printed if the diskboot is unencoded. The actual function that gets the dancing bits values is a few calls deeper.
Don't forget what the H stands for.
