CN17500C/N1750 - Building OS/2 Device Drivers

= Course N1750 - Building OS/2 Device Drivers =

Synopsis
You'll learn to develop, compile, install, and test device driver programs for the OS/2 1.3 and 2.X platforms.

How you will benefit
You'll be able to:
 * Develop, compile, install, and test device driver programs
 * Understand programming and operational characteristics common to both character and block device drivers
 * Grasp the structure and operation of OS/2 device drivers
 * Design and implement an OS/2 device driver for a peripheral
 * Understand bimodal operation (real and protected-model), ROM BIOS compatibility support, interrupt handling, serialization, and the use of device helper services
