* Please set local bus speed using kernel parameter idebus
* for example, "idebus=33" stands for 33Mhz VLbus
* To activate controller support, use "ide0=qd65xx"
- * To enable tuning, use "ide0=autotune"
- * To enable second channel tuning (qd6580 only), use "ide1=autotune"
+ * To enable tuning, use "hda=autotune hdb=autotune"
+ * To enable 2nd channel tuning (qd6580 only), use "hdc=autotune hdd=autotune"
