A method for Launch WIN.COM of NT in DOS ? or VM in DOS ?

[Cpcdos]

Hi,

I would know how launch win.com of windows 2k / XP from DOS ?

For this message "can not run in dos mode" , I use HxDOS extender for launch PE format/WIN32 executable in DOS, WIN.COM launches,
i have flickers and a small white square in middle of screen, and a return in dos ...

i'm aware that NT kernel don't use DOS...

And...
If is not possible, there are a solution for execute a VM in DOS ? or a very good emulator ?

Thank!

Hi,

DOS is an OS and NT based kernels are also OSes - unlike Win95 which ran on top of DOS. You wouldn't expect to be able to run the Linux kernel on top of MS-DOS....

What are you trying to achieve and why? Perhaps there's a better alternative solution?

Cheers,
Adam

You can't do it. Windows NT is not a DOS application, and it expects to run on top of "bare metal" - nothing else. Or at least a sophisticated virtual machine, which makes it think that it is doing so. I would be very surprised if you could find something like that for MS-DOS - especially now that it has been off the market for more than twenty years.

Yeah I understand ..


But on this program http://www.japheth.de/HX.html
With this extender i can run DosBox or QEMU on DOS
I have test with DLL(s) emulation (opengl32 / SDL) with this program, in dos it work !

If you are satisfied with qemu on top of DOS, why not just run a VM on bare metal?
Is there any very special reason for the DOS?

This reminds me of an early thread by Antti.

You can't run XP on top of the DOS. The so-called NT-family (NT3.1, NT3.5, NT4.0, W2000, XP, WS2003, XP64, MCE2005) don't have WIN.COM file that could be launched from DOS command line. They are based on NTLDR technique. NTLDR is second stage NT loader that is booted by boot sector and immediately switches CPU to protected mode. The DOS-based line of Microsoft's OS is the following: Win 1.0, 2.0, 3.0, 3.11, Win95, Win98, Win98SE, WinME. These OS can be launched on top of the DOS. The modern line starting from Vista is also booted like classic NT-family but they switched to BOOTMGR second stage loader.
