Does the motherboard support Pentium III Coppermine processors?
All BIOSes for the Tacoma motherboards from version 1.90 onwards include the microcode for Pentium III Coppermine processors. The actual support of such processor is, howevwer, dependant on the voltage regulator of the motherboard. That regulator must be able to provide the correct voltage for Pentium III Coppermine processors. Tacoma motherboards with part number 6733070700 or higher have such a voltage regulator, thus they support Pentium III Coppermine processors. The part number can be found on a label on the motherboard.
