I am trying to install 386bsd on my 386/16 (a Mitsubishi system with 6
megs). I have a 70 meg CDC Wren II drive (it is an MFM based drive),
which has quite a few bad blocks (nothing out of the ordinary, but a few
more then BSD seems to be happy with).  Anyway, some of the blocks seem
to be in the inode table (when formatting the entire drive for bsd
inodes 3250 -> 3253 are bad).  So, I have two questions:
1) Is it possible to use bsd with bad blocks in the inode table.
2) I think the answer is yes, that I just have to mark them with bad144.
 I have had little luck getting bad144 to work at all.  Usaully I get
messages saying that the label is bad, but I am unsure as to what that
means.  Also, how do sector and cylinder numbers map to ufs blocks?

thanks,
alex
