I just finished installing Gentoo on a Blue&White, so I can offer some
advice. Don't trouble yourself at first with the hardware (which bus
the HD is plugged in to, jumpers, etc.) Just install Gentoo to
/dev/hdc. Now once you boot into your kernel, more than likely the
devices will be ordered /dev/hda - hard drive /dev/hde - CD. So then
you have to chroot in again and manually edit yaboot.conf on the
bootstrap partition to point to /dev/hda. Also, don't forget to update
your /etc/fstab to reflect the fact that the hard drive is now /dev/hda.

Hope that helps!

Thanks for the heads up!

You might need CONFIG_BLK_DEV_IDE_PMAC_ATA100FIRST in your kernel.

Thanks to Michael and Nathan for your help so far. I've
tried /dev/hda,c and e as being root upon rebooting, and every time I
get a kernel panic. I'm not totally sure why, but I've been looking
into the config to make sure I have things enabled properly (already
found that I hadn't put support for my IDE interface, but that wasn't
the only problem) Any other gotchas? I'm completely new to the Mac
hardware, so this is kind of bewildering to me!

Writing in to give more details - I do have the
CONFIG_BLK_DEV_IDE_PMAC_ATA100FIRST set in the kernel, and hda is still
showing up as hda. I also do not see any lines in the boot reporting
that the hard drive has been detected (though they scroll by pretty
quickly and it's hard to tell - is there a way to see what the dmesg was
for a kernel that didn't finish booting due to a kernel panic?) The
panic is the famous "Cannot open root device "hda8" or
unknown-block(0,0)". Well, the cdrom doesn't have an hda8 of course, so
this isn't surprising. What I'm attempting to discover is what I am
missing in the kernel config to get my hard drive correctly supported.
Further suggestions?

Sorry I'm an idiot, that was supposed to read, "and the cdrom is still
showing up as hda."

Yes, netconsole as described in Documentation/networking/netconsole.txt.

OK - now I'm really baffled - I've tried again but this time I used
genkernel. However, even the genkerneled kernel can't seem to detect my
hard drive! This time I was allowed to drop to a shell and the only hd*
was hda, my cdrom. The thing that's killing me is that the gentoo boot
cd is obviously able to do it, and I even copied the config from that cd
over as per the genkernel instructions, still to no avail.

Nathan, you mentioned having just installed on a blue&white - I assume
that these machines are enough similar that the config that you used
should be good enough to work for me too - do you think you could send
me your .config off list so I can try that out?

Here is another clue that may be found to be interesting by you ppcers -
when I boot into the live CD and dmesg, hdc (hard drive) is the last
thing to be discovered, and of course happens right after the IDE
interface is discovered. I'm wondering why it takes the boot process so
long to see my IDE controller...

Can you please post the kernel output, which you gather using
netconsole, on an http server? I guess your kernel is missing some
option, but I'm not sure which. Did you only check /dev/hd* or also what
dmesg said?

You copied the actually running config from /proc/config.gz?

Michael

I think I may have found the problem --> CMD646! It turns out that I
had not enabled support for the IDE interface in the kernel. The lspci
output was kind of obscure in helping me with this, but the dmesg of the
live CD gave me the clue! Thanks to Michael and to Nathan for your
help! I am now inside a shiny new ppc environment on my shiny old G3 :)

> You copied the actually running config from /proc/config.gz?

Indeed. Thanks for your help!
