Like windows?
Theres lots of os's like (and unlike) windows. Or do you just mean windows?

There is no sure way. Most operating systems run in protected mode. The few that dont are nothing more than dos style single tasking environment.

If you want something where your app can tell 'windows' to switch to real mode then as far as im aware you cant. Why would windows let the apps control the environment, thats like saying 'heres the memory heap dive in and take what you need'. That's not the point of an operating system. System States are not controllable by tasks.

VM86 mode is only there for backward compatability. If you need 'read' real mode, then you're not going to find it in the form of MS windows or a gui.

VM86 mode is about as good as it gets without resorting to plain old DOS (with no windows).
