Modes(Addressing)
| Mode | Stage | Register Bits | Description |
|---|---|---|---|
| Real Mode | Boot | 16 | 寄存器16位，地址总线20位，最大寻址空间为1M（2^20字节），PhysicalAddress = Segment * 16 + Offset，不支持多任务 |
| Protected Mode | Kernel | 不提供直接的无力内存访问，需要通过操作系统进行地址转换 | |
| Virtual 8086 Mode | Real Mode in Protected Mode |
