Thanks for the reply. I'm DEFINITELY interested in trying what you suggest. QUESTION: (This would help simplify my work.) From all the vortex-diag output, of before and after values, do you have the bit patterns that I COULD use to put my machines back in unhappy mode? I can, perhaps rediscover them on my own, or go to other machines but if you have the information handy, it would save me effort. -wdc
