Historically it depended whether you had a PATA controller with SATA bridge, a SATA controller with SATA drives, a PATA controller with PATA drives or a SATA controller with PATA bridge. Often the bridges are on the card or mainboard. So some VIA systems would historically use /dev/hda for the first SATA device. Even more fun is stuff like Jmicron where the BIOS settings determined whether PATA or SATA was /dev/hda Alan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
