hmm, when I %cat /proc/cpuinfo I get processor :0 at the top of a list of stuff then, just below that, processor :1 at the top of an identical list. Are those two cores? I think CONFIG_MCORE2=y is recommended for the Atom. Does MCORE2 mean 'two cores' or 'core no.2'? The <help> window(under Symmetric multi-processor support) says nothing about 'cores' Are 'cores' and 'cpus' the same thing in this context? Well, this has taken me all morning and half the afternoon and I haven't even started 'Power management...' options yet. I'll just say 'yes' to SMP and carry on. Hopefully have the definitive answer by midnight and I can make the darn kernel. mw mw
