Hi Clint
It's probably not missing - just appears and disappears faster on faster hardware. I've not seen the boot blob in years :-)
Roderick (Mensys) posted this to the eCSTestTeam mailing list earlier this month about eCS 2.2 GA:-
"Last nuts and bolds. Lot of issue's resolved. Hopefully at the end of this month."
Notice it is a "hopefully" not a definitely.
Regards
Pete
