447 it a good choice for systems with very tight memory restrictions, or
448 for systems with only older MFM/RLL/ESDI drives. Choosing the old
449 driver can save 13 KB or so of kernel memory.

451 If you want to use this driver together with the new one you have
452 to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
453 driver from probing the primary interface.

455 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
456 instead of this one. For more detailed information, read the
