Hi Brad,
Thanks for the info. It inspired me to drag out one of the other macs in my collection to test this out. It's a Performa 637cd, and it booted the kernel just perfectly right up to the point of looking for a ramdisk or rootfs which, as there wasn't any on the floppy, it panicked. And I must say Tux looks quite nice on a CRT monitor compared to the LCD in my Powerbook ;-)
I wish I could test this on my Mac Classic II, but it currently doesn't have enough ram to boot linux (only 4mb). Also, I'm hoping to get a few more m68k Macs so I can continue testing. It looks like a couple people will be donating their old macs (two more different powerbooks and a Mac IIci). Now I just need more desk space. . .
Thanks,
J Silverman

Now I got some interesting news. I took Stephen
Marenka's config for
a 2.6.25.2 kernel and chopped out just enough to
squeeze the kernel
on a single floppy. And guess what? It actually
booted! Well, sort
of. The kernel messages started scrolling like normal
then the whole
machine spontaneously shut off. I seen this happen
once before when
I had the fpu emulation option turned on. So I turned
it off and
tried again. This time it didn't boot. It
stopped at the same
place as before.
The spontaneous reboot or shutdown on a PowerBook is
generally a
result of not having a good PMU driver. If the driver drops
a
message, the PMU considers the OS to have crashed and kills
off
the whole system. It's kind of a painful process. I
have done
all my work on desktop systems, primarily the IIfx. I think
Finn
has mostly been using Quadra systems for development.
