*** Linux disables the "pre-fetch" or "read-ahead" modes of these interfaces

*** Linux disables the "prefetch" ("readahead") mode of the RZ1000

*** Use of the "serialize" option is no longer necessary.

*** For the CMD640, linux disables "IRQ unmasking" (hdparm -u1) on any
*** drive for which the "prefetch" mode of the CMD640 is turned on.
*** If "prefetch" is disabled (hdparm -p8), then "IRQ unmasking" can be
*** used again.

*** For the CMD640, linux disables "32bit I/O" (hdparm -c1) on any drive
*** for which the "prefetch" mode of the CMD640 is turned off.
*** If "prefetch" is enabled (hdparm -p9), then "32bit I/O" can be

*** The CMD640 is also used on some Vesa Local Bus (VLB) cards, and is *NOT*
