Does anyone know how the versabus adaptor maps Versabus IRQ's and BR's
to cpu Interrupt processor levels? I have gone through the versabus
boards and the boards versabus IRQ's and BR's do not map cleanly to cpu IPL's
(I need to figure out what spl level to use to block out a device given
its IRQ and BR).
