Anyway I am sure the FreeBSD and NetBSD teams : could have some fun with this after they have tired with porting 4.4 : BSD. This sort of evil non-canonical SMP has been attempted by other vendors before.. I'd say your best bet is to wait until the LiteSS or LinuxSS single-servers become available.. Port Mach 3.0 to your MP hardware platform an use that. Since the Unix single-server relies upon the Mach kernel to schedule threads onto the processor pool, it should be cleaner to achieve a real SMP Unix implementation. BTW- The Mach 3.0 code for several SMP machines is freely available. Sequent Symmetry (24 x i386) and Omron Luna (4 x MC88000) come to mind. -- Jim Doyle
