positions, and the technical knowledge or quality required for these jobs. Determine the confidence in your career and see what options you may have in the software industry. In your software career, you may encounter various job opportunities. The development of each job varies with the characteristics or personality of each person. For the ever-changing IT industry, it is helpful to determine the target and plan in advance.While introducing each type of job, we will learn about some common to
address in the address space. The CPU can directly read and write data directly from three places: memory address space, port, CPU internal register. 14.1-Port Read/writethe CPU and the chip on which the port resides are connected via address bus, so the port address and memory address are transmitted via address bus. In a PC system, the CPU can locate up to 64KB different ports. The address range for the port is 0~65535.The read/write to the port can only be used in and out instructions. diff

Push al; push register (high/low) byte (invalid command), must be a word, 16-Bit Data push 8 h; push constant (invalid command)

Why do we have to worry about this nonsense? Because by default the A20 address line is disabled at boot time, so the operating system has to find out how to enable it, and that may be nontrivial since the details depend on the chipset used.Classical A20 control, via the keyboard controller
