Hi, One of my major struggles in doing audio with my powerbook is the lack of a programmable RTC. I have a via-pmu based pmac and use the genrtc module. More presicely I need these iotctls: RTC_IRQP_SET, RTC_PIE_ON, RTC_PIE_OFF. Would it be possible/wise to add these using via-pmu timer 1? Is there a PMU command for this, or would it require direct IO like via_calibrate_decr()? Thanks, -- Martin
