( > see > <http://www.everymac.com/systems/apple/powermac_g4/stats/powermac_g4_500_dp > .html>) ATA-1 through ATA-8 is a standard for the ATA bus. E.g. ATA-6 (revision 6 of the ATA standard) is also called Ultra-ATA/133. For more information you can visit Wikipedia: http://en.wikipedia.org/wiki/Parallel_ATA#Features_introduced_with_each_ATA_revision This is what what you can see at the everymac.com specs page. The names used in Open Firmware for the device paths don't necessarilly correlate with the used ATA standard revision. If you had two buses, both ATA-5 Standard (i.e. Ultra-ATA/100), what would be their names in Open Firmware so the buses can be distinguished? So, the Open Firmware names are: ATA-3 is used for the second (most of the times slower) bus for the optical drive and the ZIP drive/floppy drive. ATA-4 is used for the primary hard disk drives bus. I believe these names are used for all Power Macs, regardless which ATA procotol version they are providing. Even my G3 B&W (not even a Keylargo IDE chip and thus no LBA-48 support) has these namings in Open Firmware. Anyway, please check in your Open Firmware for the correct names.
