	  This enhanced support may be necessary for Linux to be able to
	  access the 3rd/4th drives in some systems. It may also enable
	  setting of higher speed I/O rates to improve system performance with
	  these chipsets. Most of these also require special kernel boot
	  parameters to actually turn on the support at runtime; you can find
	  a list of these in the file <file:Documentation/ide.txt>.

config BLK_DEV_4DRIVES
	bool "Generic 4 drives/port support"
	help
	  Certain older chipsets, including the Tekram 690CD, use a single set
	  of I/O ports at 0x1f0 to control up to four drives, instead of the
	  customary two drives per port. Support for this can be enabled at
	  runtime using the "ide0=four" kernel boot parameter if you say Y
	  here.

	  There are unclear terms in ATA-4 and ATA-5 standards how certain
	  hardware (an 80c ribbon) should be detected. Different interpretations
	  of the standards have been released in hardware. This causes problems:

config BLK_DEV_HD_ONLY
	bool "Old hard disk (MFM/RLL/IDE) driver"
	depends on BLK_DEV_IDE=n
	help
	  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 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
	  <http://www.tldp.org/docs.html#howto>.
