- This setting is irrelevant for most IDE disks, with direct memory
- access, to which multiple sector mode does not apply. Multiple sector
- mode is a feature of most modern IDE hard drives, permitting the
- transfer of multiple sectors per Programmed Input/Output interrupt,
- rather than the usual one sector per interrupt. When this feature is
- enabled, it can reduce operating system overhead for disk Programmed
- Input/Output. On some systems, it also can increase the data
- throughput of Programmed Input/Output. Some drives, however, seemed
- to run slower with multiple sector mode enabled. Some drives claimed
- to support multiple sector mode, but lost data at some settings.
- Under rare circumstances, such failures could result in massive
- filesystem corruption.

- command line "hdx=ide-scsi" (try "man bootparam" or see the

+ may grab those ports and thus can prevent the controller

+
+ Also, currently, IDE generic doesn't allow IRQ sharing
+ meaning that the IRQs it grabs won't be available to other

- There are two drivers for MFM/RLL/IDE hard disks. Most people use
- the newer enhanced driver, but this old one is still around for two
- reasons. Some older systems have strange timing problems and seem to
- work only with the old driver (which itself does not work with some
- newer systems). The other reason is that the old driver is smaller,
- since it lacks the enhanced functionality of the new one. This makes
- it a good choice for systems with very tight memory restrictions, or
- for systems with only older MFM/RLL/ESDI drives. Choosing the old
- driver can save 13 KB or so of kernel memory.
-
- If you want to use this driver together with the new one you have
- to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
- driver from probing the primary interface.
-
- If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
- instead of this one. For more detailed information, read the
- Disk-HOWTO, available from
