Well, both pmax and vax are little endian, and the pmax have its disklabel
at the same place as vax, but the boot block layout is different.

To make a filesystem from a decstation I would assume that this would
be a simple way (even if netboot is simpler :-)

# disklabel -W sd0		Enable writing to boot sector
# dd if=hpboot of=/dev/rsd0c	Write the vax boot sector, destroys old label
# disklabel sd0 > /tmp/hej	Save proto disklabel
# disklabel -R sd0 /tmp/hej	Write fresh disklabel
# disklabel -e -r sd0		Edit new disklabel
# newfs sd0blah...		Newfs the new partitions.

This is totally untested but it may work :-)
