There are unclear terms in ATA-4 and ATA-5 standards how certain
hardware (an 80c ribbon) should be detected. Different interpretations
of the standards have been released in hardware. This causes problems:
for example, a host with Ultra Mode 4 (or higher) will not run
in that mode with an 80c ribbon.

bool "Old hard disk (MFM/RLL/IDE) driver"
depends on BLK_DEV_IDE=n
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>.
