Nope. Some companies sold processor upgrades for the ZIF sockets ages ago,
but I doubt they're findable now. Maybe eBay.

On the other hand, L2 cache upgrades do work, and NetBSD knows how to turn
on the L2 cache on those.

I don't think that changing the CPU will make the job any easier. But it
may make the job more satisfying when it's done.

It [Microsoft's security ad on the NY Times editorial page] simply seeks
to pass responsibility from a corporation with $40 billion in the bank
earning interest, onto its users - saying: "if we goof, we're not to
blame. You just haven't used our stuff CORRECTLY".
