Hi,
A motherboard is considered the heart of the system, not as a peripheral.
The XP license allows for upgrading of most hardware and peripherals on any
license. However, there is one major difference between an OEM and a retail
license. A retail license is transferable to other machines, an OEM license
usually is not. What this means is that a retail license can be transferred
to a new motherboard, but an OEM license usually cannot. Without knowing
what type of license you have, I cannot tell you if you can upgrade your
motherboard without purchasing a new license or not. In general, OEM
licenses are either sold as such (OEM full license, sometimes with a piece
of hardware) or are preinstalled on a machine (eg: HP, Compaq, Dell,
Gateway, Packard Bell, and numerous others).
