Early probing (4 sec. break) question

Hello,

booting verbose gives me:

OK set boot_verbose=YES
OK boot

---> What does it do here? It takes three seconds obviously doing nothing,
	would be nice if there was a output line so you don't assume the box
	may be hanging! In non verbose mode the Calibrating... line doesn't
	show up so to the user there's another second of visably doing nothing!

Thanks, -Harry
