This paper describes in detail the authors exploration in this direction from the perspective of the writing of operating system, and then experiments with pyos. This is the last part of the content, which will describe in detail the programming part of the 8259A chip, which will be described in detail in the next article for interrupt handling and program validation in the operating system. This article is just a bit of my experience in the process of
