OK, here is my question: Why is the CPU speed reported as 801.83MHz?
Is there something really wrong with my setup here? I have this machine
configured to dual boot with the other OS being the x64 version of XP,
and it reports a 2.2GHz CPU (for what it's worth...).
Is this just some cosmetic thing, or is my CPU really running that slow?
