As a manufacturer of Fast-20 disk drives, I can report on what we see in the 
"real world" in respect to negotiating for a 50 nsec transfer period.

We have found that different host adapters are using different values; some 
use 0Ch while others use 0Dh. We will honor either one of these values as 
meaning that the adapter "really" wants the 50 nsec value. In turn, we return 
the same value sent by the host.
