Or would it? The LBA48 property is added "persistently" (meaning, it stays installed even after the machine is rebooted, or is powered-off), but only to the on-mobo IDE channel(s). There is one LBA48 installer script for the HD bus, and another for the optical bus, as these two buses are usually 2:1 ... higher performance for the HD bus and lower performance for the optical bus. Once these properties have been "persistently" added, these are present during booting, too, so you could ... theoretically ... boot from a single-partition 500 GB drive. The main difference between this and the "High-Cap kext" is the kext is only available after booting has been completed, therefore it cannot be used during the booting process itself, thereby forcing OS X to reside "below the line". The LBA48 property exists solely for the on-mobo ATA channels, and it does not, and cannot be used for the-off-mobo channels, which are PCI cards. Besides which, the off-mobo ATA channels are really being modeled as SCSI and not as PATA, and there is no limit for a true SCSI, although there is that very same 131,072 MB limit for a simulated SCSI. > > Just buy a PCI SATA controller card? > Always an option, and as most new drive developments is being done on SATA drives, this is the smart choice, although one with an investment in large PATA drives might prefer the first choice, LBA48. --~--~---------~--~----~------------~-------~--~----~ 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.
