OS2DD102 - OS/2 1.x Device Drivers

Enabling hardware support for multiple OS/2 applications.

Objective
To expedite Independent Hardware Vendors (IHV) support of OS/2 2.x by writing Physical Device Drivers (PDD) to support PC hardware. This will permit the hardware to be used by multiple OS/2 applications.

This class will identify the protocol on how to communicate with the kernel using the DevHlp interface. Installation and debug techniques will also be covered.

Target audience
IBM or IHV programmers who code device drivers for...
 * a. I/O interfaces (i.e. Serial, parallel, etc)


 * b. Bus type: ISA, EISA, VLB, or MCA.

Attendee prerequisites

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

Length

 * 5 days
