Dear Debian:
I am having troubles starting the Penguin-18 bootstrap installer on my
PowerBook 520. I start the Penguin booter, set the setting to point to
the 'linux' kernel and 'root.bin' ram disk file, set 'root=/dev/ram'
in the command line, save these settings as defaults, choose 'Boot
Now', and it stops on a white screen with black lettering (monochrome
screen) saying:
This error would appear to be the kernel trying to read from an
address that doesn't have anything. The address in question is
0x50f08000, which is in the block reserved from I/O devices.
This particular address would normally be the NCR5380 SCSI controller
registers, but I don't know if your machine really has that. The
different source trees I have laying around disagree. If your machine
doesn't have this chip, but the kernel thinks it does, that could
easily cause a problem just like this one. I really couldn't tell
you for sure what SCSI chip this model has, but that appears to
be the issue.
If I had the System.map for your kernel, I could look up the addresses
and see if it is the mac_scsi driver causing the problem.
