DOS ain't dead - How to detect FreeDOS kernel from Turbo Pascal program?

How to detect FreeDOS kernel from Turbo Pascal program? (Developers)

Hello,

I am looking for a method of detection of running FreeDOS kernel from Turbo Pascal compiled program. Because under FreeDOS various shells can be loaded (for example FreeCOM can be replaced by 4DOS) this cannot be a method referring to simple shell call. What I need is to find if my Pascal program runs under FreeDOS kernel, regardless of the command interpreter used.

For now I use ugly and dirty code of type "if exist {boot drive}\kernel.sys then RunningUnderFreeDOS" but this ugliness fails miserably when multiboot (and multikernel) configuration is working because while kernel.sys is present, it doesn't mean it is loaded.
