(Ultra-DMA uses both edges of the clock, so there can be more transitions than EIDE, and the spectrum will be higher in freq, also with more sensitivity to clock skew, due to timing constraints.) -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
