Commodore 1581 - Auto Boot Loader

AUTO BOOT LOADER
During some operations (power-up reset, burst INQURE, burst
QUERY, an initialize command) the 1581 will automatically look for a
file or the disk named 'COPYRIGHT CBM 86' that is a USR type-file.
The format of the file is the same as that described previously for the
utility loader. If it is present, the file is automatically loaded and
executed.
The automatic loading of this file can be disabled by either
renaming it, setting the appropriate flag in the BAM sectors (see
Appendix C), or by setting a flag variable in RAM to disable further
autoboots (see JDEJAVU jump table vector in Chapter 10).
At the end of the autobooted program it should return control to
the 1581 via the JCBMBOOTRTN jump table vector.
