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.
If you are experiencing compatibility or performance problems, you
MAY try to answer Y here. However, it does not necessarily solve
any of your problems, it could even cause more of them.
It is normally safe to answer Y; however, the default is N.
