Cheers. I haven't had time to read that yet. I've also uploaded some 
1.4H RPCINST kernel to my web site. It may be possible to install 1.4 and 
1.4.1 using these but I haven't tried yet. The kernel does boot okay 
though. I can also upload kernels for SHARK and CATS if people want 
them.

For anyone who wants to give it a try the URL is
