Moving from Dual-CPU to Single

[Jay Barry]

Hello,

I'm currently running XP Professional on a dual-P3 600 machine. A
nice new P4 2600 is arriving shortly, and in an ideal world I'd pull
the drive out of the old system and throw it into the new one without
a reinstallation.

Most of the hardware changes can be dealt with, but something I am
very unsure of is how to move from the multi-processor kernel back to
a single processor one.

Assuming I can get past the dual->single move, is this approach
workable or should I back everything up and do a reinstallation?

Thanks,
jay

Hi Jay

It's perfectly possible that such a change in hardware could happen without
anything more than any necessary BIOS tweaks followed by, probably, a repair
install (also known as an in-place upgrade). But, in a situation where you
are already prepared (in terms of system configuration) to back-up and
re-install, a full clean re-installation should always be the preferred
route.

Hope that helps
Pete

Greetings --

Normally, unless the new motherboard is virtually identical to the
old one (same chipset, IDE controllers, etc), you'll need to perform a
repair (a.k.a. in-place upgrade) installation, at the very least:

This may also require re-activation. If it's been more than 120
days since you last activated that specific Product Key, you'll most
likely be able to activate via the Internet without problem. If it's
been less, you might have to make a 5 minute phone call.

Bruce and Pete,

Thank you both for your replies, the in-place upgrade was painless.
