  *                      "Prefetch" mode bit OFF for ide disks and

+ *  Version 0.08        Need to force prefetch for CDs and other non-disk
+ *                      devices. (not sure which devices exactly need

  *
  *  HT-6560B EIDE-controller support
  *  To activate controller support use kernel parameter "ide0=ht6560b".
  *  Use hdparm utility to enable PIO mode support.
