All currently manufactured AMD parts are 3.5 volts if I'm not mistaken (contact www.amd.com and browse around). IBM's line of processors do not have floating point units the last time I looked. I think it is safe to say that ANY 100Mhz part is 3.5 volt. There are some companies that take 3.5 volt parts and install them on a litlle circuit board with regulator that plugs into a 5V 486 socket. I don't know how good these are at running FreeBSD. Does anyone out there have any idea? ====================================== When philosophy conflicts with reality, choose reality.
