Question about using sysprep to switch motherboards in Windows XP

Okay, I'm about to upgrade from an ASUS A7N266-VM motherboard (nVidia nForce 220-D chipset with IGP-64 and MCP-D) with an Athlon XP 1700 to a Biostar M7NCG 400 motherboard (nForce2 chipset, also IGP/MCP) with a new Athlon XP 2500+ (Barton core). I'm running a pretty new copy of Windows XP that I activated only last month.

I've tried to do lots of research and there seems to be a strong indication that things are much more likely to go smoothly if I use sysprep before switching the drives. The question I have is, which sysprep options should I use? -activated -reseal?

It's the activation question that has me stymied. If I just do -reseal, it sounds like I'll have to reactivate XP. I thought -activated might be a way around that, but I'm not sure I understand what the consequences of using -activated might be.

Any tips from those of you who've had success switching motherboards under XP would be much appreciated! Keep in mind that I'm using a motherboard with everything (network, video, audio) onboard.

Thanks!

yes, you can go ahead and reseal.

I stated the following from one of my other threads:

"You run sysprep and "RESEAL" Windows XP.
Then you put the new board in, and it re-activates Windows XP and populates the device manager list.
You do need to re-activate with the same key-code, and if you exhaust that number of activations, it will prompt you to call
Microsoft and you get a new release key at no cost from them over the phone.

If you have hardware conflicts with the new motherboard and any device, you will have extensive problems noticeable by memory dumps."

I've swapped several boards in different machines. One ended up being a bad move.
I had no way of knowing that an older ATI card would conflict with a newer MSI board. Therefore the whole Win XP install became corrupt. I had to start all over on that machine.
Just an example to learn from and understand that it is still a difficult process.
