FAQ (please search the archives in the future). The 'HTT' bit in the Features line just means that your processor implements the registers that enumerate logical processors. In other words, that feature means that we can ask the processor how many logical cores it has. It can claim to only have one core though. If it actually has multiple cores then we print the message during boot that you noticed in the other guy's dmesg. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
