S/390 Partners in Development: ThinkPad Enabled for S/390

An IBM Redbooks publication


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 Redbooks publication 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.
