I'm currently running a Blue and White G3 400 and want to install this G4 with AltiVec in it because i'm running OS X 10.2 and want the performace gain.The upgrade is an XLR8 G4 ZIF @ 466MHz compatible with beige and Blue and white G3s.The CPU is in perfect condition.I set the jumpers on the CPU for my system correctly, install the CPU, turn on the system and get about 3 or 4 beeps and the system wont start up.I try to upgrade my G3 firmware to 1.1 but the installer tells me my firmware is already up to date.Anyone know what to do so i get this working?
