If that's as far as it gets then it seems that the boot block
is unable to read the root directory.  It should be printing
out each directory entry it finds, and it obviously hasn't found
anything.  You might want to mount the filesystem and make sure 
it's O.K.  

Beyond that is FCode debygging.  Boot with -DV.  Once you get the
message "The file just loaded does not appear to be executable."
you enable debug on an interesting function, say search-directory
and tell the boot block to read a file:

ok debug search-directory
ok " /ofwboot" do-boot

Once it gets to the routine under debug you can single-step through
it to see where it hangs.

Hm.  It should have printed a number in there somewhere.

It should not have a stach depth change.

I'm suspecting your bootblock is corrupt somehow.  How are you 
generating it?
