Or should that be 2 cylinders? as in first partition starts at 1, next
one at 1 +2 ?

at the beginning of the first bsd partition. I must say this all
sounds rather complicated to me as I have an entire ide disk dedicated
to bsd and didn't have to worry about any sort of translation. As far
as I understand, translation is only necessary if you are trying to
coexist with a DOS partition. This made life easy as the disk just
contains bsd partitions, and the first partition in the disklabel can
simply have an offset of 0. The procedure was just to disklabel it
with the real geometry and newfs it and write bootblocks to it.

Good luck,
