There's ample evidence that you often don't know what you're talking about, but it doesn't stop you. As an example in a long list of them, you never go further to elucidate your stoopid musical theories.

I'm not in any way into IT and computers, but I doubt that the notion of "operating system" applies for a computer such as those which control injection. As far as I know, it's just simple code flashed onto an EP-ROM, in a binary form. There are no programs to execute or files to read. As Jim said, there are certainly strong "barriers" to prevent "foreign" and unwanted code to run and possibly jeopardize the behavior of the injectors. Does the notion of a virus apply there ? I'm not sure. -- remplacez "lesptt" par "laposte" pour me joindre substitute "laposte" for "lesptt" to reach me
