Yes!  Do not fault Fry's Electronics or the motherboard manufacturer.

Essentially, the motherboard supports both XP and non-XP versions of the
processor.  You may safely(1) "transform" your Athlon 1500+ processor into
an Athlon XP 2200, change the "CPU Speed" setting.  I am fairly sure
that the proper setting is "133/133" and that "166/133" is an
overclocking option, but I have a slower processor.

(1) I say safely because you really do have the XP version of the
    processor which has been rated at a certain level.  My guess is that
    a normal Athlon 1500+ may be clocked up to an Athlon XP 2200, but it
    would exceed the original processor specifications.

PS: I am not sure if the situation is similar with the P4.  I have very
little experience with them.
