I have a beta-test copy of XENIX 386, so it's possible that the final release might differ, though it's hard to imagine how much. From this keyboard, XENIX 386 2.2.1-beta looks like XENIX 286 2.2.1 with demand paged virtual memory and 386 development support, with many (not all) utilities recompiled in 386 mode. It does not support streams, RFS, or any fancy networking, or, at least, the interfaces aren't documented and the kernel doesn't have any symbols which would lead you to believe that they are there. I suspect that the comment above is mild hype, referring to the ultimate migration of SCO XENIX 386 into the Microsoft/ISC/AT&T 386 common OS base, meaning that if it ain't completely V.3 now, it will be upgraded to that over the next year or so. This is all speculation on my part. I don't see the lack of streams, etc., as a big loss for now, though I suppose they are eventually desirable. I will say that anyone running XENIX 286 on a 386 machine is crazy not to be running XENIX 386--the difference in performance is dramatic. The C compiler can generate 286 objects as well as 386 objects, so developers for the 286 are covered. People hacking for their own pleasure will love the 386 environment--all sorts of things which never could possibly work on the 286 (can you say GNU Emacs?) now compile and run. The MH mail system runs wonderfully-- it used to run out of memory all the time in 286 small model and large model was impossible because of the amount of initialized data. -- Steve Dyer dyer@harvard.harvard.edu dyer@spdcc.COM aka {ihnp4,harvard,linus,ima,bbn,m2c}!spdcc!dyer
