OK, from RedHat

    3.20.4. SMP Motherboards, GRUB, and LILO

This section is specific to SMP motherboards only. SMP, short for=20
Symmetric Multiprocessing, is a computer architecture providing fast=20
performance by making multiple CPUs available to complete individual=20
processes simultaneously (multiprocessing).

If the installation program detects an SMP motherboard on your system,=20
it will automatically create two boot loader entries.

Note 	*Note*
  =09

Intel=AE Pentium=AE 4 systems with hyperthreading will have an SMP kernel=
=20
installed by default.

The two GRUB entries will be Red Hat Linux (/kernel version/) and Red=20
Hat Linux (/kernel version/-smp). The Red Hat Linux (/kernel=20
version/-smp) will boot by default. However, if you have trouble with=20
the SMP kernel, you can elect to boot the Red Hat Linux (/kernel=20
version/) entry instead. You will retain all the functionality as=20
before, but you will only be operating with a single processor.

The two LILO entries will be linux and linux-up. The linux entry will=20
boot by default. However, if you have trouble with the SMP kernel, you=20
can elect to boot the linux-up entry instead. You will retain all the=20
functionality as before, but you will only be operating with a single=20
processor.

------------------------

So, as I read this, and maybe it might work (or at least the machine=20
might start) on other systems, but all I see is "Pentium 4 with=20
hyperthreading" as an exception. The original poster didn't say a word=20
about what his hardware situation was. I was trying to read minds and=20
didn't know about this processor's special properties.

All I have known before today, was just like this from wikipedia.org

-------------------
*Symmetric Multiprocessing*, or *SMP*, is a multiprocessor=20
<http://en.wikipedia.org/wiki/Multiprocessor> computer architecture=20
where two or more identical processors are connected to a single shared=20
main memory <http://en.wikipedia.org/wiki/Main_memory>. Most common=20
multiprocessor systems today use an SMP architecture.
