为什么我们不能立即移动数据段寄存器?。
8086- why can't we move an immediate data into segment register?
一个逻辑地址包含了段寄存器的说明符及偏移量。
A logical address consists of a segment register specifier and offset.
要使用给定的段描述符，它的值需载入段寄存器中。
To use a given segment descriptor, its value is loaded into one of the segment registers.
更新段寄存器时，与其相应的段描述符必须在核心内存中修改，然后重新载入段寄存器。
In order to update a segment register, the corresponding segment descriptor must be modified in kernel memory and then reloaded into the segment register.
每次将段选择器加载到段寄存器中时，对应的段描述符都会从内存加载到相匹配的不可编程CPU寄存器中。
Each time a segment selector is loaded on to segment registers, the corresponding segment descriptor is loaded from memory into a matching non-programmable CPU register.
在保护模式下，哪个寄存器引用栈段描述符。
In protected mode, which register references the descriptor for the stack segment?
最简单的方法是将转换因子手动放入.data 段中，并将其直接加载到寄存器中。
The easiest way to do this is to put the conversion factor in the .data section manually and load it directly in.
除了段描述符的号码以外，这些寄存器的内容对所有软件来说都是不可访问的。
Other than segment descriptor numbers, the contents of these registers are inaccessible to all software.
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.
CS寄存器有两个部分：可见段选择子部分和隐藏的基地址部分。
The CS register has two parts: the visible segment selector part and the hidden base address part.
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).
