[rescue] 3-1-4-3 beep error codes on Sun Ultra20 m2 system

[Jerry Kemp]

Hello Andrew,

Thank you for the post.

I had seen some of the pages under /ultra20.ws/ , but I had overlooked this one.

the motherboard LED code for me is 80, which on this page provided maps to "Reserved".

My understanding is/was that the Ultra20 M2 motherboard was a completely different motherboard than was used on the original Ultra 
20.  I can share that my motherboard looks nothing like the motherboard layout depicted in the picture(s).

Thanks again,

Jerry
