No, this limit was absolutely and finally removed with the Quicksilver 2002, not the MDD (although it was indeed removed in the MDD). But, this limit could be conditionally and temporarily/semi- permanently removed with all G4s. The "LBA48 property" is in all G4s that I own, but I only own AGP video G4s, not the earlier PCI video G4s. These properties ... one for the HD bus and another for the optical bus ... are there for large drive support, but these are not enabled, unless and until you do something to enable them, which takes a script in your TERMINAL window to effect. Search for 'LBA48' and I'm sure you'll find the scripts and their installation instructions. > ... but does my PowerMac G4 Sawtooth AGP Graphics > have a maximum limit of 128GB or a maximum limit per drive of 128GB. > The limit applies on a per-device basis. HOWEVER, the property applies on a bus basis. IOW, if you enable the LBA48 property on the HD bus, then any and all devices attached to the HD bus will have the LBA48 property, but the optical bus won't. You have to enable the optical bus separately. > I have a 20GB boot drive (primary master) and a 20GB on the same cable > (primary slave).

If you want to try applying the so-called LBA48 property enablement method, this will add the large drive property to your boot ROM, wherein this property is stored in your Mac's NVRAM. It will remain there, and enabled, until you cause the NVRAM to be reset. Another method is the Intech High-Cap kext, which applies only after booting. As the High-Cap kext appears not to work with 10.5, I have elected to apply the LBA48 property to my Digital Audio G4 (dual 1.0 GHz), and I use this property with complete transparency across 10.3, 10.4 and 10.5. In every case, I am using the highest level of each OS, and with all applicable updates. N.B. The High-Cap applies to all buses collectively, not just one. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
