I just re-read the section in the handbook.  Step 6 says to install the 
boot blocks with disklabel.  Maybe this is the part I've missed? 

The bsdlabel man page shows this example:

bsdlabel -B da0s1

da0 is my boot disk.  It is labeled as follows:

blacklamb# bsdlabel da0s1
# /dev/da0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:  1024000        0    4.2BSD     2048 16384 64008
  c: 17783112        0    unused        0     0         # "raw" part, 
don't edit
  d: 16759112  1024000    4.2BSD     2048 16384 28552

So can I safely issue this command without destroying the data on my drive?

Thanks again,

Drew
