Disabled HTT in the kernel but not the BIOS?

This is fine. It still shows it even though it will only load 0 and 2.
If you are really worried, turn it off in bios.

Subject: Disabled HTT in the kernel but not the BIOS?
I have a dual Xeon/HTT server that I run with
set to 0. At boot, it detects 4 CPUs:
FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu2 (AP): APIC ID: 6
cpu3 (AP): APIC ID: 7
but top confirms that only processors 0 and 2 are actually running. So,
than top being unwilling to report more than 50% CPU load, are there any
other problems with running like this, such as the cache being split for
benefit of the HTT that I'm not enabling? I can live with the cosmetic
glitch, but don't want to take a pointless performance hit.
