By default the system will detect a HTT processor, but can only launch
the second 'virtual' CPU core if you recompile the kernel with the SMP
option enabled.

I'm personally unclear why it'd be necessary to disable HTT in the
BIOS if you're using a non-SMP kernel on a uniproc box.

I'm experiencing some strangeness with a uniproc HTT-capable machine
and SATA with either SMP or non-SMP kernels, so I'll try turning off
HTT in the BIOS later this week and see if that helps.
