FWIW, I don't have a HT option in my bios. i just updated the bios to the
latest version from Dell and still no option.

Maybe they put the wrong CPU's into my workstation that is classified to
not have HT XEON Cpus?

If that's the case, can I tweak something to ignore the bios and turn on
HT?

Anyway, I'm sure it's an Intel thing.... 1-bit never made me feel so
ripped off... ;)
