LinuxQuestions.org - Lilo and Multi-boot x86 / x86

Hi,

I decided that it was about time I tried out 64bit Slack today.

I've installed it beside my 32bit installation in logical partitions:

Code:

pwatk@laptop:~$ cat /proc/partitions 

major minor  #blocks  name



  8        0  312571224 sda

  8        1    995998 sda1    <--- swap

  8        2  20000925 sda2    <--- 32bit /

  8        3  134761252 sda3    <--- 32bit /home

  8        4          1 sda4    

  8        5  20972826 sda5    <--- 64bit /

  8        6  135837576 sda6    <--- 64bit /home

Everything has installed fine and boots using the huge kernel but I'm having a few issues with lilo and booting the generic kernel.

My first hurdle is amending my lilo.conf so I can boot both installations which is proving to be a task (I've never found lilo that intuitive anyway).

Here's my current config can someone tell me where I'm going wrong here because I keep getting a fatal error because lilo can't find the kernels from my other installation:

Code:

# LILO configuration file

# generated by 'liloconfig'

#

# Start LILO global section

# Append any additional kernel parameters:

append="vt.default_utf8=0"

boot = /dev/sda



# Boot BMP Image.

# Bitmap in BMP format: 640x480x8

  bitmap = /boot/slack.bmp

# Menu colors (foreground, background, shadow, highlighted

# foreground, highlighted background, highlighted shadow):

  bmp-colors = 255,0,255,0,255,0

# Location of the option table: location x, location y, number of

# columns, lines per column (max 15), "spill" (this is how many

# entries must be in the first column before the next begins to

# be used.  We don't specify it here, as there's just one column.

  bmp-table = 60,6,1,16

# Timer location x, timer location y, foreground color,

# background color, shadow color.

  bmp-timer = 65,27,0,255



# Standard menu.

# Or, you can comment out the bitmap menu above and 

# use a boot message with the standard menu:

#message = /boot/boot_message.txt



# Wait until the timeout to boot (if commented out, boot the

# first entry immediately):

prompt

# Timeout before the first entry boots.

# This is given in tenths of a second, so 600 for every minute:

timeout = 300

# Override dangerous defaults that rewrite the partition table:

change-rules

  label = Linux

  read-only

# Linux bootable partition config ends

My next issue is creating a initrd for the generic kernel, I keep getting a kernel panic regarding the root partition being unmountable.

I used a script I made ages ago to create the initrd (I've never had issues with it before). Again can someone help me track down the problem here:

Code:

#!/bin/sh



KERNEL=$(uname -r)

MODULES=usbhid:ehci-hcd:ohci-hcd

ROOTDEV=$(df | grep " /$" | awk {'print $1'})

ROOTFS=$(df -T | grep " /$" | awk {'print $2'})

SWAP=$(awk 'NR==2 {print $1}' /proc/swaps)            # Use first swap partition found

KEYMAP=uk



echo "

mkinitrd -c -k ${KERNEL} -m ${ROOTFS}:${MODULES} \\

  -f ${ROOTFS} -r ${ROOTDEV} -h ${SWAP} -l ${KEYMAP}

"

mkinitrd -c -k ${KERNEL} -m ${ROOTFS}:${MODULES} -f ${ROOTFS} -r ${ROOTDEV} -h ${SWAP} -l ${KEYMAP}

Thanks
