Not on any of the multi-CPU motherboards I ever worked with. The CPUs
shared SDRAM and used the same physical address space. They both saw
the same PCI/ISA buses and all other peripherals. There was no way you
could run two different OSes without some sort of hypervisor -- there
was no practical difference between them and a modern multi-core CPU.
