[...] Henry's original question mentioned that the same question was posted to comp.unix.ultrix but got no responses. For the sake of completeness it probably should be mentioned here that there was a subsequent answer there (from Jeff Mogul) that not only gave the same information as Han's post here, but also added that other clock rates were possible and offered a modified clock driver to implement them. --bruce
