hi There. I aquired recently an octane, without any OS .I want to know
which netBSD is OK for this hardware, and where i can download it. there
is an external CDROM connected on it. thanks !!

Quoting Eric Rapilly :

Unfortunately NetBSD doesn't run on the Octane. Linux had some
experimental support at some point, but I get the impression it has
been abandoned. Your best (and perhaps only) bet is probably to chase
down from IRIX media and install that.

Regards,
Steve
