Vio is the I/O voltage of the CPU.
My Pentium 3 has a Vio voltage of 3.3v, so it runs off 3.3v from the PSU.
My Pentium 4 has a Vio voltage of 1.5v(same as Vcore), and it gets it's power from the 12v(because it's the same as Vcore, and Vcore comes from 12v).
Britney machines have a Vio(often referred to as Vht, for Voltage HyperTransport) of 1.2v, which comes from either the 5v or 3.3v(I don't know which one, might vary depending on mobo).

Just don't worry about. Keep it at default.
