If you set the MB to about 3.5 volts then you'll be just about right. Assuming there is a ready way to add the diode in series with your existing PS, between it and the CPU. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
