+ 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 unsure, say N.
+ 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>.
