As you discovered, the problem is mapping which slice on BSD corresponds to which slice on Linux. booting BSD with the -v option (Boot: -v) <-at the boot prompt that shoudl print out verbose information about how BSD views each slice.. you should then be able to work out which is which sorry I can't be much more help. julian On Sun, 14 Dec 1997, Bryan Batten wrote: > Hi Julian, > > Thanks for your input regarding my problem.
