config BLK_DEV_HD_ONLY

	bool "Old hard disk (MFM/RLL/IDE) driver"

	depends on !ARM || ARCH_RPC || ARCH_SHARK || BROKEN

	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 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

	  <http://www.tldp.org/docs.html#howto>.
