Ho riesumato il mio vecchio G4 per dargli una rinfrescata, ho acquistati MAX POWER Processor Upgrades G4 7447a, mi viene inviato assieme un CD con il nuovo firmware da installare prima

di montare il processore, seguo il procedimento alla lettera ma non me lo accetta.

Se chi è più preparato di me (non ci vuole molto) mi sa dire se

sbaglio o se probabilmente non va bene per il mio Mac.


Allego dati del mio Mac e parte manuale installazione.

This package contains:

• CD-ROM with manual and firmware installation

Pre-Installation Instructions:

Before proceeding, refer to the illustrations in this manual to familiarize yourself with the Newer Technology MAXPower G4 processor card. The Newer Technology MAXPower G4 card plugs into a socket on the motherboard of the Mac. Your Mac may vary slightly from the illustrations; don’t panic! It is not difficult.

Before installing your card, if you plan to use OS9 (actually boot from OS 9, as opposed to running Classic in OS X) you must remove the CPU Plugins file from the “/System Folder/Extensions/Multiprocessing/†folder after booting using the original CPU.

Firmware Update:

IMPORTANT: This upgrade REQUIRES theNewer Technology 7447A Firmware Updateprovided on CD or it WILL NOT WORK.

1. Your computer must have the latest Apple Boot ROM version for your particular model of G4.

2. To determine what version Apple Boot ROM your computer has, run Apple System Profiler (System Profiler in OS X) and look under Hardware Overview.

3. If your computer has an earlier version than what is listed below, download the latest version and follow the instructions.
