1037 depends on !ARM || ARCH_RPC || ARCH_SHARK || BROKEN
1038 help
1039 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1040 the newer enhanced driver, but this old one is still around for two
1041 reasons. Some older systems have strange timing problems and seem to
1042 work only with the old driver (which itself does not work with some
1043 newer systems). The other reason is that the old driver is smaller,
1044 since it lacks the enhanced functionality of the new one. This makes
1045 it a good choice for systems with very tight memory restrictions, or
1046 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1047 driver can save 13 KB or so of kernel memory.
1048
1049 If you want to use this driver together with the new one you have
1050 to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
1051 driver from probing the primary interface.
1052
1053 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1054 instead of this one. For more detailed information, read the
1055 Disk-HOWTO, available from
1056 <http://www.tldp.org/docs.html#howto>.
