Re: M4000 failing to boot Debian Sparc64

Hi Frank,

Thank you for your fast answer. I also thought when installing that it was
an incompatibility problem with the processor architecture, as you stated.

However, having a look at the wiki (https://wiki.debian.org/Sparc64) it
seems to me that machines with a sun4u SPARC VII+ processor should be able
to run it, right? Our M4000 has a VII+ processor.

Maybe I have not fully understood the wiki or your message, therefore sorry
if I'm wrong.

Best regards.
