检查点机制的状态检查操作就是将进程在该运行时刻的用户级寄存器上下文和用户数据段保存到检查点文件中。
Statecheck operation of checkpoint preserves the user register context and user data segment of process checkpointed at this time to checkpoint file.
当设置好这些数据结构,代码段以及系统寄存器之后,可以通过设置控制寄存器CR0的PE位(第0位)为1来进入保护模式。
With these data structures, code modules, and system registers initialized, the processor can be switched to protected mode by loading control register CR0 with a value that sets the PE flag (bit 0).
