BIOS revision history noting dual-core was added in rev.K: http://www.shuttle.com/share/fae/hq/...readmefn25.htm

If you have a Shuttle SN25P equipped with an AMD Athlon 64 X2 processor running Windows XP and are experiencing hangs, especially during periods of high-speed USB2 activity, AND running in USB 1.1-only or single-core (/onecpu in boot.ini) modes clears up the problem, please contact Shuttle if you haven't done so already and get a case number assigned to your problem. The front line techs are sympathetic, but to back them up, we end-users need to raise the visibility of this particular problem to Shuttle management.
