I think that some of the early 386s had bugs in their 32 bit multiply instructions. I remember I had to upgrade a machine before I could run Xenix386 on it. Those were the days - running Unix and GNU Emacs on a 1 megabyte machine (might have been two - my memory is a bit dim). It worked pretty well as long as you quit out from emacs before trying to compile anything. -- Doug Rabson, RenderMorphics Ltd. Mail: dfr@render.com Phone: +44 71 266 5090 FAX: +44 71 266 1623
