Re: Secure Boot Manager

["Jeff" <jeffr76 () yahoo com>]

I have had a similar problem that I solved with gsx server(Vmware)
this way the volumes could not be read.
it was a little slow but it worked on ok and was secure enough
we used grub to make sure that you could not boot the computer and the
vmware images were stored on an encrypted file
