I've just recently picked up a new motherboard (and a few other toys),
including a single core Athlon 64 3000+ processor. The intention is to
use this processor for a few months, then upgrade to a dual core CPU.

My understanding is that the dual core CPU will need a different HAL. Is
this the case, and if so, can I switch later without reinstalling?

I know it's possible to go from dual-CPU to single-CPU, but I recall
that it's not possible to go the other way without a lot of hassle. With
that in mind is there any way I can install the SMP HAL without having a
dual core CPU installed during installation?

Thanks in advance (and responses in the form of a URL are more then
welcome. I've done some reading but I can't find an answer to this
exact question)

Are you tired of having your hands cut off by snowblowers?

One question: Why buy a single core, only to upgrade a"few months" as you say
to a dual core?

That's a waste of money. If you are tight on money because you want to get
the single core now, why just save the cash that you would have bought the
3000+ CPU and put it towards the dual core down the road?

First, make certain that you do any necessary BIOS upgrade *before* you
install the new processor.
Then, install the processor and do a repair install using the Windows
installation disc.

I was hoping to avoid a repair install, although I'll do it if I need
to. There isn't any way to trick Windows into installing the
SMP-capable HAL in the first place is there?

Because I have pans for the 3000+ CPU down the road... So it won't be
going to waste either, I just can't justify the cash for two upgrades at
the same time.

The 3000+ CPU will end up replacing a 300MHz server in my basement, and
that server will eventually replace the 133MHz box I'm using as a
firewall, which will allow me to increase the grade of encryption used
on my VPN. However, the other end of the VPN won't be upgraded for 5-6
months either, so there is little reason to upgrade everything across
the board, but I may as well get a new toy now rather then waiting

It depends on what HAL your system uses at present. See the following link:

http://support.microsoft.com/?kbid=309283

In the past I have upgraded a couple of Celeron's to P4's with
hyperthreading. The new CPU was recognised and the ACPI Multiprocessor HAL
was correctly loaded on the first boot with no user interaction.
