You don't have to press the check button to "use" the ok prompt. 
Pressing <esc> when the chime sounds and it will drop to ok.

You can abuse the TS mfg tag to permanently disable pretty boot.  Pretty 
boot is disabled if TS != SHIP so:

ok change-tag TS show

will make pretty boot disabled always until you change the tag. 'show' 
can be any 4 letters it just has to be the same length as 'SHIP' or 
change-tag won't work.  Could could also delete-tag TS and then add-tag 
TS <somestring>.  Just don't use the strings 'SMT', 'ASSY, 'FINAL' or 
'RUNIN' as they will cause various stages of the manufacturing procedure 
to try and run.
