问题描述
在Intel 64& IA-32体系结构手册第3A卷，第9章处理器管理和初始化"，我发现了以下内容:
In the Intel 64 & IA-32 architecutures manual vol 3A, Chapter 9 Processor Management and Initialization, I found the the following:
这是否意味着旧版16位&在IA-32e模式下运行的操作系统上，32位应用程序可以与64位应用程序共存.
Does this mean that legacy 16-bit & 32-bit application can coexist with 64-bit application on an operating system running in IA-32e mode.
但是，据我所知，传统的16位代码通常不受64位操作系统支持.如果支持，如何启动16位应用程序?
But as I know, legacy 16-bit code is generally not supported by 64-bit operating system. If it is supported, how can I startup a 16-bit application?
推荐答案
16位DOS应用程序无法在64位Windows上运行，因为在长模式下无法使用virtual-8086模式
16-bit DOS apps can't run under 64-bit Windows, because virtual-8086 mode isn't available in long mode
但是16位保护模式仍然可用，因此技术上可以运行16位Windows 3.x应用程序.这就是葡萄酒 .不幸的是，尽管64位Windows无法具有相同的功能，但原因不是不，因为64位模式无法运行16位指令，而是因为重要部分已经增加.
However 16-bit protected mode is still available, so technically it's possible to run 16-bit Windows 3.x apps. That's how Wine runs 16-bit Windows apps in 64-bit Linux. Unfortunately 64-bit Windows doesn't have the same capability, although the reason is not because 64-bit mode cannot run 16-bit instructions but because the significant part has been increased.

因此，如果要在64位Windows上运行16位应用程序，则必须使用虚拟机
So if you want to run 16-bit apps on 64-bit Windows you have to use a virtual machine
