   Sorry to post, but I couldn't find a valid path to Andy.  I have just
had the same problem.  I have a copy of the 640K PC distribution, that
I want to get up and running on my 512K AT.  I will need to remake the
kernel at some point to use at_wini.c.  As a first step I proceeded to
create the AT disk set from the proto files in the proto.a archive on
the tools diskette and mkfs (running under MINIX).  I get precisely
the same error as Chris no matter what proto file is used.  Even a
minimal proto file (e.g. only a root directory and an empty
subdirectory) creates only the root directory before giving the error
message.  I then made an empty root file system using the mkfs option
on the startup menu and copied the neccesary files to create a 
root file system of the correct size.  But, as pointed out in the 
READ_ME file in the distribution, since mknod cannot add sizes to the
special files it creates, all the files in /dev have size 0, instead
of 512 (for mem, kmem, etc.), 1200 for at0, at1, and so on.

  Is there a fix?

Thanks,
Mike
