characteristics of the address [1]. Therefore, its 4-bit low address should be blocked. It should be noted that the memory address is the physical address of the system. When Windows is running in protection mode, it must be converted to a linear address to directly read and write the memory space. Articles about this conversion method are common and will not be described here. The above program provides a method to read the base address in the confi
