It's OBP2 - both the "2.30" and the presence of zs in the device tree
indicate that.

Does prom patch fails for you?  I tested it on my OBP2 box.  Also I
don't understand the reference to F-code.  prompatch.c doesn't use
F-code (binary), it uses textual representation.

Try to break into prom and before booting NetBSD issue these commands:

    " /obio/su" open-dev d# 13 " interrupts" integer-attribute close-dev

(you can also add them to NVRAM).


OBP3 (which is OFW) is a different story.  Since PROM in those
machines lives at f000.0000 - the address where NetBSD kernel wants to
live, you cannot boot stock kernel (actaully, it needs a real a.out or
elf boot program, so you cannot use stock boot.net either).

My current work-around is to use a kernel that starts at e800.0000 and
skip the prom addresses when kernel is initialized.
