I'm using pata-cmd64x for a few month now on my G3 powermac. So far no problems except it only runs in UDMA/25 mode instead of UDMA/33 as the ide driver does. And of course - no cdrom or zip because they are connected to the Heathrow controller... scsi0 : pata_cmd64x scsi1 : pata_cmd64x ata1: PATA max UDMA/25 cmd 0xfd63d090 ctl 0xfd63d082 bmdma 0xfd63d050 irq 0 ata2: PATA max UDMA/25 cmd 0xfd63d070 ctl 0xfd63d062 bmdma 0xfd63d058 irq 0 ata1.00: ata_hpa_resize 1: sectors = 312581808, hpa_sectors = 312581808 ata1.00: ATA-7: SAMSUNG SP1654N, BV100-50, max UDMA/100 ata1.00: 312581808 sectors, multi 16: LBA48 pata_cmd64x: active 3 recovery 1 setup 1. ata1.00: ata_hpa_resize 1: sectors = 312581808, hpa_sectors = 312581808 ata1.00: configured for UDMA/25 scsi 0:0:0:0: Direct-Access ATA SAMSUNG SP1654N BV10 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 312581808 512-byte hardware sectors (160042 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 0:0:0:0: [sda] 312581808 512-byte hardware sectors (160042 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: [mac] sda1 sda2 sda3 sda4 sda5 sda6 sda7 sd 0:0:0:0: [sda] Attached SCSI disk > I'm not aware of anyone having done any PPC ports yet, although a couple > of people have asked and said they would look at it.
