I've tested only on my own rig with 'known good' 80-wire cables and similar UDMA/66 HD's from Quantum & Seagate without any problems as a single master and a master/slave setup. I've also tested the IBM-DJNA-371350 as a single master but it still complains about the 80-wire. Here's the full output for the controller and drives: amd74xx 0000:00:06.0: UDMA133 controller amd74xx 0000:00:06.0: IDE controller (0x10de:0x03ec rev 0xa2) amd74xx 0000:00:06.0: IDE port disabled amd74xx 0000:00:06.0: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xf000-0xf007 Probing IDE interface ide0... hda: IC35L020AVVA07-0, ATA DISK drive hdb: IBM-DJNA-371350, ATA DISK drive hda: host max PIO5 wanted PIO255(auto-tune) selected PIO4 hda: UDMA/100 mode selected hdb: host max PIO5 wanted PIO255(auto-tune) selected PIO4 hdb: skipping word 93 validity check hdb: UDMA/66 mode selected ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hda: max request size: 128KiB hda: 39102336 sectors (20020 MB) w/1863KiB Cache, CHS=38792/16/63 hda: cache flushes supported hda: hda1 hda2 hdb: max request size: 128KiB hdb: 26712000 sectors (13676 MB) w/1966KiB Cache, CHS=26500/16/63 hdb: cache flushes not supported hdb: hdb1 hdb2 ____________________________________________________________ Click here for great quotes from top international movers! http://thirdpartyoffers.juno.com/TGL2131/fc/BLSrjnsKdC5Yn1q3PFnPdCgRLI4c75mnvWkMCAAJlN0ufwRLtHzCJ2EfhC4/ -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
