QNX4 Multiple Cores

For the old QNX2 and QNX4 RTOS

I think that the only option for QNX 4 was to specify which priority on each of the two chained interrupt controllers was highest. This was a kernel option you could send as a parameter at boot time, but only once. So for example you could have interrupt 3 be the highest, and then the order would be 3, 4, 5, 6, 7, 0, 1, 2. Since 2 was the cascade, 8-15 would then have lowest priority. You could also specify which of these interrupts had the highest priority.
