The bus master works in 64bits?

Of course… And I don’t claim that every case of “RTFM” is justified but there are certainly times where the person asking the question is just being lazy.
The phone book example was somewhat of a “fun” example. Many better examples exist.

Tax attorneys don’t read the entire tax code but they know how to find the answer.
Doctors don’t read every medical publication but they know how to find an answer.
etc…
My point is that not reading the manual is not an excuse for not trying to find an answer.
