From my knowledge, AMD64 populates ACPI cpu tables with all processors, including every core - the only oddity might be info about where those 'cores' are - Since AMD64 is a NUMA, it should be somewhere :) However, it all depends on BIOS (although those motherboards which boast the sign 'dual-core support' should include it) and what I said complies to 64-bit mode. In 32-bit, it should present standard Intel MP 1.4 tables.... I think :P -- Paweł Lasek
