I enabled it in my BIOS, but found that the system's periodic syncs caused this to not work. So then I changed kern.update to be some ridiculously high value around 10 hours. Today I found that this was a _really_ bad idea, when I was toying with my sound drivers and the system froze. I lost a lot of info; luckily most of it was easily replaceable. So can anyone tell me the "right" way to do this? thanks. -tim
