Mark Pizzolato 4d817f1deb VAX: Added support for the DEQNA device on Ultrix 1.x. Henry Bent observed that the deqna driver in this OS counted on older DEQNA firmware which automatically enabled interrupts after a software reset.
CPU Idle detection for this OS is now supported and the combination of SET CPU IDLE=ULTRIX-1.X and explicitly using a DEQNA device (SET XQ TYPE=DEQNA) will enable the automatic enabling of device interrupt generation.
