Some IDE controllers only update ID fields such as sector information on specific commands such as the DIAG command. The master/slave device is therefore selected both before and after sending the DIAG command; otherwise reading the IDE registers yields the master's ID fields. (Reza's patch originally *moved* the master/slave selection from after the DIAG command before it, however Feng asked for the original master/slave select to be preserved; effectively making the master/slave select *bracket* the DIAG command. See this subthread: <http://thread.gmane.org/gmane.comp.bios.tianocore.devel/10545/focus=10550>.)
