- Okay, I've finally learned that OS/2 is not quite the perfect OS for
- lab environments. Maybe I long for a bit of the control of DOS days. Anyway,
- I have to write my own device driver to access memory mapped controllers on
- a digital to analog (No - of course the manufacturer has no intention of
- creating DD in the forseeable future).
-
- I need help. I've got the development kits for OS/2 1.2 and 2.0. They include
- some minimal examples of device drivers, but no real documentation. Can
- someone tell me where to get adequate documentation to write a trivial device
- driver (it will be really stupid). Book suggestions? Pay for more software
- from IBM?
-
- Second request: Does anyone have an example device driver (in masm) fully
- functional they would make available to me. I need examples of DevHlp calls
- to get mapping of physical memory. Any help most greatly appreciated.
