 Everything else is rejected with a "BAD OPTION" message.
 
+For legacy IDE VLB host drivers (ali14xx/dtc2278/ht6560b/qd65xx/umc8672)
+you need to explicitly enable probing by using "probe" kernel parameter,
+i.e. to enable probing for ALI M14xx chipsets (ali14xx host driver) use:
+
+* "ali14xx.probe" boot option when ali14xx driver is built-in the kernel
+
+* "probe" module parameter when ali14xx driver is compiled as module
+  ("modprobe ali14xx probe")
