In the first two sections, we loaded a piece of code into system memory through a floppy disk, and instructed the CPU to execute the code that was added to the memory, in fact, the operating system kernel was loaded. But we load the code, the maximum can only be a byte, an operating system kernel, less than hundreds of trillion, thus, the system kernel can not directly read into the system memory from the floppy
