Does boot0 use / save the existing MBR (there already is code in there to l=
for  an f11 key press then boot to Acronis's standalone restorer (It=20
looks like a tailored Linux :))=2C if not boot to 'active slice')?
Does FreeBSD's slice / partition boot block have enough info to boot FreeBS=
D   =20
if another boot manager selects it? Thinking I could possibly add FreeBSD's
slice to Win 7's list of target OS's? =20
slice 1 is Win XP
slice 2 is FreeBSD (/=2C page=2C /usr=2C /var=2C /tmp & /home BSD partition=
slice 3 is Win 7 RC
slice 4 is Acronis's hidden recovery setup   =20
It appears that the Acronis' MBR looks for an f11 key press=20
(if found boot Acronis=2C if not boot the 'active partition').=20
Active partition was Win 7's boot manager which had Win 7 and=20
Win XP as targets with Win XP as it's default).
Acronis's standalone boot menu knows itself and Win 7's boot manager.
I'm guessing whatever wrote the MBR saved the old boot code=2C
so it could use it as an alternate target=2C (if one hit the
the trigger key by mistake).
