It is my understanding that if the LBA48 property has been introduced to O.F. "persistently", then a volume which is larger than 128 GB may indeed be the boot volume. But, it is still safer to limit the boot volume to two partitions, the first of which is 128 GB (131,072 MB, actual capacity) with the remainder being used for data storage which is not boot-dependent. Thereafter, the other volumes may be larger than 128 GB. Just a short refresher course: 1) the basic support, which is pre-MDD, is LBA28, 2) support for LBA48 before or during boot may be added "persistently" using the O.F. hack, and 3) support for LBA48 after boot may be added using the Intech High-Cap kernel extension, for appropriate versions of MacOS X, and 4) LBA48 really means that the OS software sends TWO commands (CDBs) to the controller, the first of which contains the first 28 bits, and the second of which contains the remaining 20 bits). The only PowerPC Mac which I still have on my desk is a Mirror Drive Door model, and the MDD models all have LBA48 permanently available. My MDD machine was supplied with two very large HDDs, and both seem to work appropriately. The machine also included two DVD burners which is certainly a luxury. -- -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
