* There is a 25/33MHz switch in configuration
* register, but driver is written for use at any frequency which get
* (use idebus=xx to select PCI bus speed).
- * Use hda=autotune and hdb=autotune for automatical tune of the PIO modes.
- * If you get strange results, do not use this and set PIO manually
- * by hdparm.

* Version 0.1, Nov 8, 1996
