OS2DD301 - OS/2 PM Video Device Driver

OS/2 PM Video Device Driver - Course OS2DD301

OS/2 1.x/2.x Presentation Manager Video device driver

Objective
To expedite Independent Hardware Vendors (IHV) support of OS/2 1.x/2.x by writing Presentation Manager Device Drivers (PM DD) to support various Video Display boards.

This class will cover the core PM DD modules used to interface OS/2 applications to the display; this will include support for WIN and GPI calls. Graphics engine interfacing will be covered in detail.

Target audience
IBM or IHV programmers who code device drivers for... a. Display cards b. Bus type may be: ISA, EISA, VLB, or MCA.

Attendee prerequisites
a. Programming expertise: C, MASM b. Intimate knowledge of IHV hardware & programming protocol c. Other device drivers for IHV hardware (DOS, ROM BIOS code, utilities) d. Purchased development software (OS/2 2.1, DDK, MSC 6.0, MASM 5.1)
