Thanks Jerry.  I'm so paranoid about messing up the other OS on the HD
though.  The installer's fdisk suggests an entirely different layout to
everything else I've seen:

Geometry 9729/255/63 = 156296385 sectors (76316 MB)
Offset      Size(ST)   End        Name   PType  Desc    Subtype   Flags
         0         63         62      -  12     unused  0
        63    5981220    5981282  ad0s1   7     fat     11
   5981283   13971447   19952729  ad0s2   8     freebsd 165
  19952730       5670   19958399      -  12     unused  0
  19958400  136337040  156295439  ad0s3   4     extended DOS, LBA 15
 156295440       6048  156301487      -  12     unused  0

If I just immediately 'Q'uit the darned thing will it not make any
changes to global drive geometry? It would probably take me several
days to get my win2k installation back to how it is now, if I lost it.

All I really want is for the installer to use the freebsd slice as is.

I'm tempted to just try UPGRADING but mergemaster always confuses me.
