Not a chance it would work. Windows NT/2K don't let silly little 16-bit
programs run wild and do things like that. You'll crash your program,
perhaps even the VDM if you're lucky, but you won't reboot the machine. If
Win9x lets you do this, then I'm glad I'm not on Win9x anymore. Under
Windows, there is an API to do it, but I don't recall the name of it. If you
executed that instruction, it would be the equivalent of a hard shutdown
(i.e. turning the power off without shutting Windows down). Then you run
into all kinds of problems such as the two FAT tables differing on FAT
partitions, the possibility of spooled disk data being lost, etc.
