I ran gentoo on my iBook G4 with little issues. So recently I tried to install gentoo on my powermac g4. However yaboot cannot find the image file. I have tried different yaboot settings all to no avail. I reloaded gentoo three different times with no success. I am attaching my fstab and yaboot.conf file. Anyone have any suggestions?

Code:
## yaboot.conf generated by yabootconfig 1.0.8
##
## run: "man yaboot.conf" for details. Do not make changes until you have!!
##
## For a dual-boot menu, add one or more of:
## bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ

boot=/dev/hda2
device=hd:
partition=4
root=/dev/hda4
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enableofboot
enablecdboot

image=/boot/kernel-3.18.16-gentoo
   label=Linux
   read-only
   append="video=ofonly"
   initrd=/boot/initramfs-genkernel-ppc-3.18.16-gentoo
   initrd-size=8192


Code:
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency).  It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#

# <fs>         <mountpoint>   <type>      <opts>      <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#/dev/BOOT      /boot      ext2      noauto,noatime   1 2
/dev/hda4      /      ext4      defaults,noatime      0 1
/dev/hda3      none      swap      sw      0 0
/dev/hde      /mnt/cdrom   auto      noauto,ro   0 0
#/dev/fd0      /mnt/floppy   auto      noauto      0 0

I think I found a problem with the Gentoo netinstall image reading OWC IDE SSDs. I have been experiencing issues with Gentoo booting after the install completed. Yaboot could not find the image file. This seemed odd to me since Debian and Ubuntu worked fine on my machine with the same drive. One thing I noticed was Gentoo was seeing my disk as a hda instead of a sda. Just to be sure I reinstalled Debian and verified that it was reading my drive as a sda drive and yaboot was loading. Could this be the root cause as why yaboot could not read my drive? Who would I place a bug report with? I really would to have Gentoo working on my Powermac I already had it working on my iBook. Thanks!

I have a G4 imac.

Here is my yaboot.conf:
Code:
boot=/dev/hda5
ofboot=/pci@f2000000/mac-io@17/ata-4@1f000/disk@0:5
device=hd:
partition=7
delay=10
timeout=40
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot

image=/boot/kernel-3.18.11-gentoo
        label=Linux
        root=/dev/hda7
        read-only

image=/boot/kernel-3.17.8-gentoo-r1
        label=Linux.old
        root=/dev/hda7
        read-only

enablecdboot
enableofboot
It works, but I'm not using genkernel or initramfs

Do you have a SSD as your hard drive?

No, just the ordinary rotating one.

I also had a lot of trouble getting yaboot to automatically boot. I could still manually boot from the command line though.

I found some reports on the forums about yaboot not recognizing ext4, so I switched to ext3. It worked after that, but I made other changes also, so I cannot be sure that was the issue.

hda, hdb, etc is for IDE drives

sda, sdb, etc. is for SATA or SCSI drives

My CDROM drive is hdb, but my USB port is sda

running dmesg can be quite informative about your system

That is the only thing I could see that would cause this. I just installed Debian Sid and now the system see my HD as a sda. I have ran Gentoo on my iBook G4 with an ext4 partition with no issues. I may later try with ext3.
