Cannot boot from 6.2 install cd

[Nick Folino]

This is my first try at fbsd on my Sun 420R.  I've tried the 6.2 boot-only
and 6.2 disc1 cd's.  It gets to this point and just hangs:

Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...
nothing to autoload yet.
jumping to kernel entry at 0xc0060000.

Any idea what is happening at this point and where to look?

Thanks,
Nick
