The Sempron 2200+ is a model 8 it seems.

Does it support powerNow! ?
Can I use that to control the multipliers?

Is it 'superlocked', i.e. would a couple of changes to
the bridges (L3, L5, L6 for ex) would allow me to
boot at a faster mutiplier or not?

Otherwise is there a tool to install on windows to use
PowerNow to cool the chip or is it built into winXP?

For ex:

has a client for win98~ 2000.

There are Sempron drivers but only for the 3100+/Athlon64

unless its a mobile sempron chip, its not going to have PowerNow!. Power Now! is basically just the same as cool n quiet except with more steps between. I dun understand why u'd need to use it neway i doubt that proc gives off a lot of heat n consumes a lot of power.

Edit - then again I'm not sure if semprons would even have powernow!
