Okay Peaopl I finally broke down and bought the power logix g4 1.6ghz 7447a upgrade. My Digital Audio 533 mhz now is 1.6ghz and It's like 3 times as fast as it was. and it worked. It's got a new life, now just HAVE TO UPGRADE THE RAM .75GBS MORE I was just wondering which linux distro runs good with upgraded g4s. Yippie.
