That all needs to be redone. The VM stuff is actually pretty easy since Mach 2.5 ran on a VAX and the code for pmap.c is available from CMU. The hard part is all the CPU support, memopry exception handlers, locore, and device drivers. As someone else has remarked, it's only worth doing if you love VAXen -- if all you want is a BSD machine, get an Intel. -- Paul Vixie Redwood City, CA <paul@vix.com> decwrl!vixie!paul
