You would need to check your new dmesg to see if it is. Currently HT is only available on P4 Xeons. The acpi_cpu entries might just be because the BIOS in your box is built using a ASL template shared among many motherboards or some such. The acpi_cpu entries are not the same as entries in the mptable or MADT per se. They use a different numbering scheme and other weirdness. I think a simple P4 I have here at work has two ACPI CPU "slots" as well actually. Hmm, nope, only has one. *shrug* You just have a weird BIOS. :) -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
