Переименуйте Catalyst OS
Компании, специализирующиеся на аутсорсинге it разбираются в этом. Можно видеть, что название CatOS в замененном модуле супервизора начинается с RTSYNC. Можно оставить систему для выполнения, как это. Можно также изменить имя файла и поддержать его как стандартное имя как показано здесь:
Access2> (enable) rename RTSYNC_cat6000-sup32pfc3k8.8-5-8.bin
cat6000-sup32pfc3k 8.8-5-8.bin
Access2> (enable) dir

После переименования файла необходимо изменить переменные загрузки.
