Re: 21A error during boot

Tech-Archive recommends: Speed Up your PC by fixing your registry

Hi again. A RAM overlay does not store any writes to the EWF partition (it
instead puts them in memory), but it still depends on the EWF partition for
configuration information. This is what distinguishes a RAM overlay from a
RAM REG overlay.

It looks like you've resolved the problem - glad to see it worked. =) Just
wanted to clarify the difference between RAM and RAM REG overlays.
