Boot probs with Suse 10.1


Hi. I'm using the Suse 10.1 GNU/Linux distro on a PPC G4 iBook installed on a 250 GB external hd. The boot partition is sda9 (in HFS format because it's required by the machine), the root partition is sda11 in the reiser fs.

When they made the distro they forgot to include a bootloader installation program for the PPC version. They have documentation at the suse page but it doesn't seem to work for me. These are my configuration files starting with /etc/fstab:

/dev/sda11 / reiserfs acl,user_xattr 1 1
/dev/sda12 /home reiserfs acl,user_xattr 1 2
/dev/sda10 swap swap defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
/dev/fd0 /media/floppy auto noauto,user,sync 0 0

And this is yaboot.cnfg:

timeout = 200
default = linux
root = /sda11
initrd = /boot/initrd-2.6.16.13-4-default
image = /pci@f4000000/firewire@e/node@00063a2800095fdd/sbp-2/disk@0:11,/boot/vmlinux-2.6.16.13-4-default
label = linux
root = /sda11
initrd = /pci@f4000000/firewire@e/node@00063a2800095fdd/sbp-2/disk@0:11,/boot/initrd

I don't know why but the computer can't see sda11. The last message I get during boot is:
waiting for /dev/sda11 to appear...................not found
How can I get it to see sda11?

Thanx in advance for any advice you might have.

This may not be a problem of the bootloader but of missing kernel modules. The SUSE standard installation may not be properly configured to load the system from USB devices. I am not sure if there are any PPC-specifics, but have a look what this guy did: http://www.linuxquestions.org/questi...d.php?t=426099

Briefly, the following modules need to be included into initrd:

ehci-hcd
ohci-hcd
uhci-hcd
usb-storage
sd_mod

Otherwise the drive cannot be recognised at the early boot stage.

This is a firewire drive, sorry for not so stating before. Are there firewire specific modules? If there are, how do I edit initrd? I am an infant at GNU/Linux.

I checked for modules that are loaded when I attach my iPOD. These are:

ieee1394
ohci1394
scsi_mod
sbp2
sd_mod
sg

Don't forget to include the hfs driver as well, otherwise your filesystem won't be recognised.

You can create an initrd with mkinitrd -m "<space separated list of modules>" or list the modules in /etc/sysconfig/kernel (the parameter about mkinitrd) and run mkinitrd without parameters (recommended as this will allow kernel updates).
