When does Windows(or WindowsXP) start virtual DOS mode?
When you open a Command Prompt window? When you run an EXE file designed for real mode ( in that case how does Windows detect that the program is designed for real mode if I assembled it with MSAM6.11 under WinXP)? Or sometime else?

afaik, when you start a 16bit executable - running a 32bit windows console mode application (like cmd.exe) doesn't start it. Open the Task Manager and look for ntvdm.exe .

It's easy for windows to see if the application is realmode or a 32bit executable - realmode apps don't have a PE file header.
