Probably both sources are wrong :-).
The only thing I can say is, I installed from 2.1 CD with atapi.flp.
HD was master and CD was slave on the primary IDE channel.
I had problems with using both IDE channels, i. e. HD master on primary
and CD master on secondary, as my IDE-chip (CMD640B) does not support
concurrent access to both channels.
