Re: It won't boot - unknow or corrupted file system

Hello

I am trying to install 9.1 ppc on an Ibook.  The installation went fine, 
despite some problems with bootstrap (I created an Applet boot partition or 
something like that).  

When I try to boot the ibook, I first get a menu 

linux (l)
cdrom (c)
openfirmware (o)
If I choose ¨l¨ yaboot comes out.  When boot finally tries to load the kernel, 
the following error message comes out:

hd:8,/vmlinuz-2.4.21-0.13mdk: unknown or corrupedt filesystem.

What did I do wrong?

Many thanks

Ed

Ed,

My guess is that the Linux kernel is not on hd:8.

You will need to get your ibook booted (probably with the Mandrake CD) 
and then run as root:
pdisk -l /dev/hda

That should show you the partition table for your internal hard drive. 
You will have to determine which partition holds the kernel. Here is a 
sample of my pdisk ouput:

[EMAIL PROTECTED] root]# pdisk -l /dev/hda

Partition map (with 512 byte blocks) on '/dev/hda'

I have /boot on my powerbook as a separate partition. So my /etc/yaboot.conf looks 
like:
#yaboot.conf - generated by DrakX
init-message="\nWelcome to Mandrake Linux!\n"
boot=/dev/hda16
ofboot=hd:16
delay=30
timeout=50
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot
enableofboot
defaultos=linux
default=linux.ext3
image=hd:11,/vmlinuz-2.4.21-0.13mdk
       label=linux
       root=/dev/hda13
       append=" devfs=mount"
       read-only
So you can see that I am booting off of partition hda11 (aka hd:11) and then it 
switches to my real root which is on parition 13
You may be able to run Mandrake tools directly. I being a terminal kind of guy would 
use chroot and edit the yaboot.conf file directly.
I hope this helps,
