 	  This is the virtual block driver for virtio.  It can be used with
           lguest or QEMU based VMMs (like KVM or Xen).  Say Y or M.

+	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>.
