Both top and /proc/cpuinfo show one processor.

Does top show one or two processors?

Subject: p4 hyper-threading
Hi,
I seem to be unable to make the hyper-threading functionality of my Pentium
4 3.2ghz processor work. I've searched google and redhat list archives and
haven't found a similar post and resolution to this so I have no idea what
is wrong.
This is an HP system, with latest BIOS
Hyper-threading is enabled in bios
Added acpismp=force to my grub boot line (kernel /vmlinuz-2 (See http://nuz-2.ora-code.com).4.20-28.7smp ro
root=/dev/hda7 hdc=ide-scsi acpismp=force) Applied every single errata
update redhat has for 7.3 Using redhat kernel: kernel-smp-2 (See http://smp-2.ora-code.com).4.20-28.7
And still top and /proc/cpuinfo only list one processor.

this should work...but this is my first p4 hyperthreaded chip.
Anyone have any other ideas of what I can check/change to make
hyper-threading work on this p4?
Thanks,
Dan
