Re: writing cdhdtape to CD

I can't check the CD at the moment, but the cdhdtape file should be a 
good place to start...

I think the cdhdtape image file I have is OK, based on the facts that 
it's the same size as this one:

ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0/alpha/installation/diskimage/cdhdtape

(there's not an md5 value for it on ftp.netbsd.org that I can check 
against) and I can dd it to a hard disk and boot the PWS from that 
disk successfully.

I've totally failed to mount cdhdtape though.  I guess I'm doing 
something wrong:

# uname -mrs
NetBSD 5.0 i386
#
# ls -li
total 3714
4659209 -rw-------  1 ray  wheel     1984 Apr 26 16:54 README.files

#

I tried mounting NetBSD-5.0/i386's boot-big.fs file using this 
approach too as a test, but kept getting this 'incorrect super block' 
error.  I'll be happy if you can point out my mistake.
