OS2DD303 - OS/2 Adapter Device Driver (ADD)

= Course OS2DD303 - Adapter Device Drivers (ADD) = OS/2 Device Drivers for SCSI or Proprietary Interfaces

Objective
This five day workshop will enable programmers to write OS/2 Adapter device drivers (ADD). An ADD communicates with SCSI or proprietary I/O interfaces which usually connect to DASD, CD-ROM, etc.

This class will identify the protocol on how the ADD communicates with the Device Manager (DMD) using the IORB interface. Installation and debug techniques will also be covered. The Developer Connection Device Driver Kit (Devcon-DDK) will be used extensively in order to build and test the ADD.

Target audience
IBM or OEM programmers who code device drivers for PC I/O interfaces such as SCSI or proprietary.

Attendee prerequisites

 * Programming expertise: C (MASM useful)
 * Have written device drivers for DASD I/O hardware (DOS device drivers, ROM BIOS, test utilities)
 * Attendee must be a licensee of the following software:
 * OS/2 2.x, OS/2 Warp
 * Developer Connection Device Driver Kit (Devcon-DDK), MSC 6.0
 * Knowledge of OS/2 Physical Device Driver (recommend attendance at OS2DD101 workshop)
