re: ofwboot versions and upgrading
ofwboot kernel status
3 3 works (my machine to be upgraded is fine)
4 4 works (another of my machines)
3 4 fails, kernel complains about bootinfo
4 3 ???
What I would like to know is:
If I put the netbsd-4 ofwboot in place on my netbsd-3 system, can I
still boot the netbsd-3 kernel (netbsd.ok) if I need to?
this should work. you can put ofwboot in as a different name as
boot that instead of the default. something like this:
ok> boot ofwboot.new netbsd.new
if new ofwboot can't boot old netbsd, that seems like a bug to
I have installed bootblk from the head of the netbsd-3 branch. Can
this load the netbsd-4 ofwboot? Answer: the files /usr/mdec/bootblk
are byte-for-byte identical on netbsd-3 and netbsd-4, so sure.
"bootblk" and "ofwboot" are separate. the former is a forth
bytecode program to load the latter, which is a normal ELF
file (32 or 64 bit.)
