For a code to be able to run with access to 64-bit registers, another kind of protected mode is employed, called longmode.
一个代码能够访问64位寄存器，采用另一种保护模式，称为长模式。

I don't know much about this longmode, but from what I have read, this mode doesn't allow the processor to create a task using the 8086 virtual mode.
我不知道这漫长的模式，但是从我读到的，这种模式不允许处理器使用虚拟8086模式创建一个任务。

The problem is that this works when the CPU is in 32-bit VPAM (Virtual Protected Address Mode), which is what an i386 OS USES, but not when the CPU is in the so-called "LongMode" that AMD introduced.
