Preface

A ThinkPad Enabled for S/390, generally known as a ThinkPad/EFS system, is the smallest S/390 currently available, and is intended for development and demonstration purposes.

It is based on an IBM ThinkPad running Linux, and the S/390 emulation product FLEX-ES. FLEX-ES is a product of Fundamental Software, Incorporated (FSI) of Fremont, California. This package (the ThinkPad, Linux, and FLEX-ES) can run all current S/390 operating systems.

This IBM Redbook introduces the ThinkPad/EFS system, describes the setup process of the system in some detail, and then describes the installation and use of an OS/390 package known as the OS/390 AD CD-ROM system.

While this publication is primarily directed at members of the IBM S/390 Partners in Development program (also known as PartnerWorld), most of the content applies to any ThinkPad/EFS system.

The author

Bill Ogden is a retired IBM Senior Technical Staff Member, still working part-time on favorite projects at the International Technical Support Organization, Poughkeepsie Center. He specializes in entry-level OS/390 and z/OS systems, writes extensively, and teaches ITSO workshops relating to these areas. Bill has been with the ITSO since 1978. Many of his projects for the last several years have been related to IBM’s S/390 Partners in Development organization.

Thanks to the following people for their contributions to this project:

Jim Obrizok, Linda Lovallo, and Frank Yolton, of the S/390 Partners in Development program, who coordinated the PID elements of the project and helped obtain required hardware.

Scott Carter, Martin Groen, Peter Ward, David MacMillan, Ray La Croix, and Tom Valerio, of Fundamental Software, Inc., who provided considerable help with the details of planning and installation.

Mike Hammock, of IntelliWare Systems, Inc., who provided useful feedback about typical system use.

Special notice

This publication is intended to help new users of ThinkPad/EFS systems better understand the platform. The information in this publication is not intended as the specification of any programming interfaces.
