INTRODUCTION ------------ This directory contains PRELIMINARY information on the Long Trail reference design. This reference design is provided by IBM to enable PowerPC OEM customers to easily build Common Hardware Reference Platform (CHRP) compatible desktop uniprocessor PowerPC systems. This ftp site is intended for Alpha customers, IBM field representatives, IBM technical marketing and key development partners. The information is not classified and may be distributed, but please use caution. DISCLAMER --------- Files may be in rough form and are generally written, or provided, for engineers and programmers to develop a Long Trail system or clone. The documents may, and often do, change frequently. It is the user's responsibility to obtain the latest version. FILE FORMAT ----------- Non-Cadence design files are generally in postscript or text format. The file names are obviously geared toward a Unix workstation. For a PC user, the files must be renamed during transfer. Several files in the pass2 subdirectory are Cadence design files. Files with a .tar suffix are compound files that have been "zipped". Files with a .Z suffix have been compressed.
