[is there a port-sparc64 list?]

Just fyi:

Here's as far as I got with an UltraSPARC 5, 128MB Memory, ATI Rage 3D
(4MB):

...

....

and there it hangs.

GAH!  And then I reboot and my PROM/NVRAM has been zeroed!
(I was going to get everything before the mainbus0 line, but can't!)

How do I reset my PROM/NVRAM?
