Possible to make a bootable CF card ROM w/o secondary disk/partiti

[Guest]

I've been reading up on using the EWF RAM Reg mode to write protect my CF
boot media, and I'm trying to determine if it allows for the protected volume
to be completely ROM in order to satisfy an industry standard requiring a
static signature.

It's my understanding that the EWF volume in this mode is stored in the
registry on the protected volume, but I am not so clear on when, if, or how
often XPe writes to the EWF volume.

Thanks.

1. You will want to use FAT as the file systems since EWF doesn't protect
the whole partition using NTFS.
2. The only time it writes to the EWF partition is when there is a change to
EWF.

Thanks a lot. I think that's all I needed to know.

This is a very interesting issue, and new information at least to me.
I was under the impression
that EWF could protect the media at leest from the filesystem, except
from some functions
like hibernation that write directly to the media. What part of an
NTFS partition is not protected
by EWF?
