About Your Power Mac G4 AGP Update
The Power Mac G4 AGP Update increases the reliability of the Rage 128 Pro graphics card in Power Mac G4 computers.
English - North American Mac OS 9.0.4 or later
We attempted to run the update on a single processor PowerMac G4 AGP with the Rage 128 Pro and the installer informed us that this machine did not need the update. Similar to an update released earlier this month, this release could be for multi-processor PowerMac G4s only, though the documentation says nothing to this affect. However, with the update being smart enough to know where it can and canit be used, you should not have any trouble if you check it on your G4.
You can find more information on the update at Appleis Web site.
