Hello all,
I'm trying to get squeeze up and running on an xserve G4 with a broken CD
drive. It doesn't seem to want to boot from an
extrnal firewire CD, but will boot OSX from an iBook set in target mode.
Oddly, it won't boot from a CD in said iBook.
Things tried so far:
Put the Xserve in target mode, install wheezy onto it via debootstrap (plus a
kernel), edited fstab and so on, ran ybin,
unmounted and rebooted. It gots to yaboot stage 1 OK, but when I press 'l', a
blue folder pops up in the middle
of the screen with the icon alternating between a question mark and the
happymac logo.
Eventually I got the bright idea of reading the ybin man page, and realized
that the iBook's Open Firmware path to the xserve's
ultra0 drive in while target mode is very different from the xserve's idea of
its own drive when booting normally. It would
seem fair to say that ofpath is 'failing', thus the necesity of specifying it
explicitly in the ybin command. I figured out the
appropriate values by booting the xserve into open firmware, corrected
yaboot.conf, and ran ybin with all options specified.
Same result.
Then I realized that in target mode, the xserve's drive is called /dev/sda by
the ibook, but to itself when booting, it's
/dev/hda, so I dug into openfirmware yet again to grab the self-referred drive
names, but with the same result.
Is my approach valid? Have I made some not-so-obvious mistake in the config or
ybin, or should I just give up and track down a
replacement CD drive?
