[rescue] Hardware fingerprinting on Ultra 5/10?

[Paul Mantz]

Sorry to derail, but I have a quick question about flashing the PROM.
I tried flashing my Ultra 5 to the latest version( that i could find
on sun.com, made somewhere around 2001), and I got some sort of error
like "cannot load, multiple bootable ELF images", when I rebooted
after telling it to boot from the updater file.  Does anyone know what
this means, and how I can get around it?
