good to know  : )

Thanks all, for your knowledge and advice.  One more latency question: in my 
BIOS, I can set the PCI latency.  It's set to 32 by default; I set it to 64 
a while ago, I think in an attempt to fix some video card / TV-capture 
related issue.  How does that number tie into the jack/ardour latency situation?
