Last question (for me...) is, I already have the "Combo Drive" factory 
installed in my MDD G4, and am ready to put a new Pioneer DVR-107D in 
the lower space.
Once installed and the machine rebooted, can I expect that header bar 
icon to display both the Combo Drive and the DVD drive?

Thanks for your help.
