The LBA48 property, which is required to support drives larger than 131,082 MB, is a protocol extension, not a hardware extension. For LBA24, the card issues one CDB (command data buffer) to the drive. For LBA48, the card issues two CDBs, each one describing 24 bits. Apple's G4 firmware can be changed to enable the LBA48 property. No PCI ATA card can be similarly enabled. Which is perhaps one very good reason to stick with Apple's on-mobo ATA controllers. --~--~---------~--~----~------------~-------~--~----~ 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.
