one number less than your current highest priority.
Important:
Run the Exec mode show boot command to verify that there are less than 10 entries in the boot.sys
file and that a higher priority entry is available (minimally there is no priority 1 entry in the boot stack).
If priority 1 is in use, you must renumber the existing entries to ensure that at least that priority is available.
The maximum number of boot stack entries that can be contained in the boot.sys file is 10. If there are already 10 entries
in the boot stack, you must delete at least one of these entries (typically, the lowest priority) and, if necessary, renumber
some or all of the other entries before proceeding. Use the no boot system priority command to delete a book stack
entry.
