	  to be probed before the ATA/66 and ATA/33 controllers. Without
	  these, those machine used to have the hard disk on hdc and the

config BLK_DEV_HD_ONLY

	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>.
