Hi Clay,
First off... I should warn you that Charon isn't using B1.0 yet. I think you may
be about to become a beta-tester, though.
Second... for use in Guide, try using B1_PATH (not USNOB1_PATH). That oughta do
the trick. Just for reference, use of B1.0 from the hard drive is documented (at
least a little) at
