I can boot from a floppy (break out of the boot and go to hd0:/netbsd) so
(if I'm thinking correctly) the system is pretty close.  The only thing
that seems amiss is the bootcode magic on the partition, which doesn't
really make any sense, since I've tried a dozen combinations of
installboot, fdisk, and everything in /usr/mdec.  The NetBSD partition is
active, and the partitions and BIOS geometry all seem to be correct.

I know there was a list of the commands that sysinst executes to set up
the partition tables.  Do you know where that is?
