/*
- *
- * Version 0.01 Initial version hacked out of ide.c
- *
- * Version 0.02 Added support for PIO modes, auto-tune
- *
- * Version 0.03 Some cleanups
- *
- * Version 0.05 PIO mode cycle timings auto-tune using bus-speed
- *
- * Version 0.06 Prefetch mode now defaults no OFF. To set
- * prefetch mode OFF/ON use "hdparm -p8/-p9".
- * Unmask irq is disabled when prefetch mode
- * is enabled.
- *
- * Version 0.07 Trying to fix CD-ROM detection problem.
- * "Prefetch" mode bit OFF for ide disks and
- * ON for anything else.
- *
- * Version 0.08 Need to force prefetch for CDs and other non-disk
- * devices. (not sure which devices exactly need
- * prefetch)
- *
* HT-6560B EIDE-controller support
* To activate controller support use kernel parameter "ide0=ht6560b".
* Use hdparm utility to enable PIO mode support.
