Who Trains SCO?

Teaching a company the inner workings of their own products is no small challenge - especially when the products are as large and intricate as SCO UnixWare and SCO OpenServer. But that's the degree of expertise we offer at ATCS.

We've taught Internals throughout SCO:

Engineering Technical Support Custom Engineering

Professional Services Kernel Engineering TEAM

Engineering Services Escalations Consulting

We've taught SCO Internals throughout the computer industry to companies such as:

Data General Fujitsu Force Computers

We customize our internals course upon request. Topics we've covered previously:

731 - Writing UnixWare 7 Device Drivers

Course Overview

Writing UnixWare 7 Device Drivers is designed for:

Experienced C programmers who would like to learn how to write a device driver.
Programmers who already know how to write device drivers for another version of UNIX or any other multi-tasking operating system.

In this course, students learn the what device drivers are and how to write them for UnixWare's multi-user, multi-tasking, multi-processor environment.

Writing UnixWare 7 Device Drivers is a high level course that is taught with task-oriented lectures and hands-on labs.

Course Objectives

By the end of this course, students will be able to:

Diagram the UnixWare architecture and explain the functionality of the major components of the kernel
Describe basic features of the Intel 386 through Pentium II I/O hardware as it relates to device drivers
Compare and contrast the various types of device drivers
Explain the synchronization mechanisms used to protect sensative resources in a single and multi-processor system.
Write, install, and use a interrupt and non-interrupt character device driver
Create demand-loadable device drivers
Create auto-configuring device drivers
Create streams device drivers
Create block-I/O device drivers
Describe the architecture of SCSI and other storage technology device drivers in UnixWare 7
