Booting on an iBook
Brian Dean
I'm trying to get an install going on my iBook, but am not getting
very far. Here's what I did:
I downloaded the macppc binary distribution for 1.4.2
Set up my FreeBSD box to respond to my iBook's BOOTP request
and tell it to load /tftpboot/netbsd (this kernel copied from
binary/kernel/netbsd-GENERIC_MD)
Reboot my iBook, holding down cmd-alt-O-F to get to open
firmware.
Issue 'boot enet:0'.
My iBook loads the kernel, but halts very quickly thereafter with the
following on the screen (typed in by hand):

I also tried this by first having my iBook load ofwboot.elf first, and
then send /usr/export/ibook as the root path. There, I had
netbsd-GENERIC_MD installed but named 'netbsd' so that it could be
found. The result was the same trap at the same instruction.
Additionally, I followed the procedures outlined at:
http://www.enchantedlearning.com/tech/netbsd_imac.shtml
which was linked to from the ppc FAQ (netbooting page) for setting up
an iMac to net-boot (ok an iBook is not an iMac, but it doesn't appear
to be too iMac specific). In this case, I extraced the full
distribution under the NFS export area, created the /dev area and so
on. In the end, the result was the same trap at the same instruction.
I saw on the macppc model support page that the iBook is supported
excepting that the built-in keyboard is not yet (as described by this
link: http://www.netbsd.org/Ports/macppc/models.html). So, I tried
booting with my iMac keyboard plugged in, but, not too surprisingly,
got the same result.
I'm hoping I'm just doing something dumb and the correct procedure for
installing onto an iBook is well-known. I'd really love to run NetBSD
on my iBook. Any and all help is greatly appreciated.
Thanks!

I can't tell you what that means, it's likely gibberish from a trashed
pointer. What is the load-size set to out of curiosity?

This doesn't matter, it's not to the point of detecting any of the
chipsets, NFS is useless until the kernel recognizes the Ethernet chip. You
should try ungzipping and booting the kernel from KERN.TGZ in the
distribution (without using ofwboot.elf) and see if it also traps. If it
does than there is likely a hardware change.

Is this the Special Edition iBook? It's possible that Apple changed some
hardware. I also believe that there have been one or two Firmware Updates
for iBook's on asu.info.apple.com that you should most definitely install if
you have not already.

No it's probably not you, it looks like Kernel issues.
