Greetings. If you have ever attempted to download and use the ABI documents from either Caldera or from SGI for the MIPS ABI and or the System V Interface Definition Fourth Edition documents, you will find that they are corrupted. I have uploaded the repaired documents in both PDF and PS format: ftp://ftp.cotw.com/ABI Ralf, would you please replace the files on the SGI FTP site with these? I have already emailed Caldera to update the documents. Thanks. -Steve -- Steven J. Hill - Embedded SW Engineer
