Tualatins have a few redefined pins, if they don't say it's compatable it probably isn't, BUT Compgeeks has an adapter for $8, AND the adapter not only allows you to use Tualatins, but also allows you to modify the detected voltage AND bus speed. For example, with that $8 adapter you COULD get a Tualatin Celeron 1100 and set it at 1.65v, 133MHz bus using the adapter. That would make it 1466MHz and provide similar performance to the PIII 1400, all for $8. So sometimes it's GOOD to "need" an adapter!
