NTVDM error message

[Dave Navarro]

As far as I know, the only way to detect Windows NT/2000 is by checking for the OS environment variable.

There's a KB article about it, but I don't remember which one. If I find it again, I'll post a link.

There is a PB/DOS function in the Source Code forum for detecting what version of Windows a DOS box is being run under (or if it is being run in OS/2), although I don't know if it works on Windoze 2000.

I hit a *similar* error in Win2K today... the cause was continual referencing of ENVIRON$("OS")... if I did it once and set a variable then the problem went away. This issues did not show up in the IDE, only when run directly or from the command-line.

Note: BIT(PBVHOST,8) does not indicate WIN2000 is running - it works fine in other versions (I've not checked NT4 though). The simpliest way I've found to tell if Win2K is active is to check the environment variable "OS=Windows_NT" with ENVIRON$.

Has anyone ever come across the NT 4 message:

NTVDM Invalid Parameter - Ignore, Exit?

It's something to do with NT's virtual Dos Machine hence NTVDM.

I'm getting this error when loading EXE's from a batch file...

TIA
