Alpha is big- or little-endian (so, it's bi-endian), Alpha is little-endian in practice. I've never heard of DEC--or anybody else for that matter--building a big-endian alpha.

But I might be mistaken. I think you are mistaken. The ARC MIPS platform, which Windows NT originally was written for, was also little-endian. -- Christian "naddy" Weisgerber naddy@mips.inka.de
