If you could turn off everything that *isn't* in DOS, you might have fun running the Linux kernel. You run DOS in an emulator on top of Linux because you can't *get* DOS to run native on that hardware. Drivers are needed that don't exist. What you probably want is a flavor of Linux modified for use in an RTOS, where a user process can preempt the kernel itself. But on modern hardware, "other time-critical programs that will carve out slices of CPU time" are likely a "Who cares?" issue. Commonly used hardware is orders of magnitude faster than the machines DOS was made to run on, and there are cases like games where you might specifically *want* to steal CPU slices, because otherwise your game runs *too* fast and is unplayable. . ______ Dennis https://plus.google.com/u/0/105128793974319004519 ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
