Hi everyone... a bit of an arb question now... I am writing an application to access an ISA card. I am using the instructions inp and outp &nbsp;to access address 0x300 but those only work for win95. As I understand it, those instructions just read the card which sounds straight forward. Now for the arb question... if I want to use winNT or some strange platform that requires a driver, I must rewrite some code. In spite of looking like a fool now, I must ask what is a driver in laymans terms? What does it do that is so special and different from inp and outp? More importantly how does it do it and how does it work? How would my program read what the driver retrieves? And the next step is what are the steps I should follow to write my own driver. Stop laughing ;-) Thanks for any clues...

ISA drivers...

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
