; Модуль парсинга - это стандартный компонент, встраиваемый во вторичный загрузчик.
; Данный модуль позволяет стандартно произвести разбор ini файла
; (и с использованием полученных данных ОС будет загружаться дальше).
; В начале найдем открывающий "[" - это будет указывать на начало
; секции. Поддерживается 1 секция это [loader], остальные секции могут иметь
; любые имена, но они должны быть заключены в в скобки []
