When I used the pre-released sys7.0b4, I found that the Blesser will
recognize the file with signature of "ZSYS". The new system(7.0b4)
has signature of "zsys", so if you want to do it, at your own risk,
you could make some modification.

I don't have releases S7.0 yet, has any one mixed the S7.0 and S6.0.x
successfully? My hard disk's volume information was changed after
I installed pre-released S7.0b4, I am really afraid of this happens
again when I install the released S7.0
