Hi All,

So, can I say "Our all '030s get panic at reboot in NetBSD-3.1,

    How about IIci ?
    Does anyone know "my '030 can reboot without panic" ?

and, it's only in '030s, all '040 works fine at reboot." ?


I dislike to see that panicked (MMU fault) screen. It makes me
panic, too.

Yes, thanks to Bjarne and Hauke.
To avoid that, I do 'shutdown -h now' then push Reset or Power-off,
but ... it's not 'graceful'. ;)

Yes, that's a good idea, too.

NetBSD reads PRAM. When PRAM has correct setting, we don't need
INIT nor CDEV in MacOS, right?

How about 32-bit dirty machines ? IIx, IIcx or SE/30 for example,
we need MODE32 and Memory Control Panel in MacOS.

IIsi is 32-bit clean, a beautifu and interesting machine, I like =20
IIsi, too.

(again)

Very interesting. I'm expecting the next of NetBSD/mac68k.
