iBCS EMULATION FOR LINUX ======================== 12 February 1997 release INTRODUCTION ------------ The iBCS kernel module for Linux provides access to the wide variety of applications available for i386 and Sparc based implementations of Unix. Support of SVR4, SVR3, Xenix and BSD is provided with the iBCS module handling the non-standard extensions made by various vendors in a completely transparent fashion on a per process basis allowing your applications from a SCO based PC to run side by side with those from a multiprocessor Wyse system on your Linux PC(*). Not only does this give Linux arguably the largest application base of any Unix but it also makes Linux the ideal tool to integrate and extend existing Unix networks. (*) It is, of course, the user's responsibility to ensure that any licensing requirements of your existing packages are adhered to.

Install it on as many machines as you like. There is no small print to read and no lawyers will pursue you for license infringement (of the iBCS emulator). If, on the other hand, you simply do not believe that anything good is free then the cost is 99 pounds sterling per machine you run the emulator on. Send this money to any iBCS developer (or developers) of your choice who I am sure will make good use of it. Alternatively you may send the money direct to the charity of your choice or use it any other way that will benefit society (or not - your choice). Supporting operating systems and applications which I don't have running is difficult to say the least. Donations of OS flavours (ideally with development system), applications and hardware is particularly welcome. Hardware, in particular, is a continuous problem. SUPPORT ------- There should be nothing in the emulator to support, however if you have questions feel free to ask the developers. If you think you have found a bug in the emulator you can employ anyone you like (including me!) to fix the problem at any price you agree. It would be appreciated if you send the patch to jaggy@purplet.demon.co.uk so it is incorporated in future releases. If you feel you cannot live without paying money regularly to someone on the off chance you may wish to ask them a question sometime then contact the developers who will be happy to discuss how much you should send them. A list of people who are believed to have contributed to the iBCS emulator is contained in the CREDITS file in the main distribution. APPLICATION VALIDATION ---------------------- In general the application vendor will be better placed to test their applications on iBCS/Linux as they will have the knowledge and test procedures to fully exercise the product. If you really do not wish to install a Linux PC and run your application yourself you will find that there are plenty of people interested in being paid to use your software for a change. Some applications that people have used successfully are listed in the COMPAT file of the main distribution. This is however a *very* small ad hoc subset of applications which work.
