The second stage boot block is simply called "boot" and resides at
the root of the root file system, as well as /usr/mdec. There's nothing
wrong with the installation of the boot blocks, it's just that the boot
blocks them selves are probably bad/broken/corrupt. I believe the
/usr/mdec is part of the base.tgz file. So you'll probably want to grab
the 1.5 base.tgz and pull out /usr/mdec over top of your existing
/usr/mdec with tar or pax. If I had time to fool with my VAX I could post
the second stage block for you. I'll see if I can bring it up when I get
home.
