As Paul said, some of these things require PInvoke's. Others are available directly from the OS or the EMDK.

Hi, Not sure there are C# calls to do this but you can PINVOKE some C calls to get this in CAD.dll CAD_GetOemVersionNumber CAD_GetOemBuildNumber CAD_GetLoaderVersionNumber There are some examples in the C EMDK look in C:\PROGRAM FILES\Motorola EMDK for C\v2.1\Samples\C\Standard\SysInfoSample\SysInfoSample.c also attached.
