I've learned a lot about the TFTP protocol these last few days...

1) Solaris 10's TFTP server implementation and the HP712 aren't compatible. the
HP wants an option that Solaris doesn't implement.

2) Using Wireshark during boot, it appears the entire LIF file is being
transferred.

3) After downloading the LIF onto another system using tftp, the md5sum matches
what's on the tftp server.

..and I still get that 'btlb' output mentioned above just before a hard hang.
No I/O error messages though.

It seems to be loading the kernel, and then something goes wrong before the
kernel runs. I doubt it's a hardware problem as I get a working install of
HP-UX 10.20 if I boot from disk; It even starts X11 with CDE.
