Since disklabel doesn't install a proper bootblock, I need to install
a bootblock that can be used by the miniroot on /dev/sdob for booting.

Having just discovered that the man pages for installboot don't seem 
to tell the whole story, how and where on sd0 do I install a bootblock
so that I can boot the miniroot, so that I can install NetBSD 1.5?

I have partitioned the disk with disklabel, and I used dd to copy the
miniroot to /dev/rsd0b. While running in nfsboot mode I can mount the
/dev/sd0b partition and see that it is all there. However, when I try
to boot from sd(,,1) I get:

no disklabel 

device not found

What am I doing wrong?

Thanks in advance.
