The first one says *DRAM ECC* is disabled on that node - not the node itself. Looks like it confuses you too.

So this is a purely informational message. There's a lot of messages like that in the kernel. I still don't understand what your problem is with this particular one.

"ECC disabled in the BIOS or no ECC capability, module will not load." - I think that sentence is explaining the situation pretty good:
either ECC checking is disabled in the BIOS
or
ECC capability cannot be detected.
What do you think it should say instead?

That message says:
"Either enable ECC checking or ..."
That first part refers to the user going into the BIOS and enabling ECC checking. It says so above too: "ECC disabled in the BIOS".
