CPU0 -> 866/256/133/1.65v SL47S CPU1 -> 866/256/133/1.70v SL48V Both are shown detected by the BIOS, and both are shown as 866MHz 133MHz busses, and 256k cache (as one would expect) > > If both CPUs are reporting the same ID, I can see how we're not > launching the second proc; We assume that ID 0 is the BSP and > additional processors have different APIC IDs. Is something really > borked here? Yep! But the acpidump -t shows 2 different ID's....
