It's more than that. The first question to ask is "which motherboards?".
ALR, Compaq, Intel, Micronics, etcetera all use slightly different approaches
to multi-processing - on some models it is true SMP and on others not.
SCO and Corollary have made a fair amount of money and have done a lot of
work to work on a lot of diverse hardware. Windows NT requires separate
HAL driver for different multi-processor Intel systems.
