Summary

The goal is to boot Knoppix from the HDD using a bootloader (grub) and three files: the ISO, a swap file, and a persistent disk image (PDI).

v01: copy files from CD

• boot with knoppix from the CD

knoppix dma noswap vga=0 1

• if you modify the environment variables, you should be able to copy and paste straight into a terminal

# set environment variables
drive=/dev/hda
partition=/dev/hda1
mountpoint=/mnt/hda1
grub_partition="(hd0,0)"  # hda1 = hd0,0 -- format is (device,partition)

# clear the entire drive - yes, all information will be lost
{ seq -f d$'\n'%g 64 -1 1 
  echo "w"
} | fdisk ${drive} >& /dev/null                                                        
fdisk -l ${drive}

# Partition drive, creating a 1 GB partition that has the bootable flag set
echo -e "n\np\n1\n1\n+1G\na\n1\np\nw" | fdisk ${drive}
fdisk -l ${drive}

# create filesystem
 mkfs.ext2 ${partition}

# rebuild /etc/fstab
 rebuildfstab -r

# mount the partition
 mount ${mountpoint}

# install grub
 grub-install --root-directory=${mountpoint} ${drive}

# copy the files from the CD to ${partition}
 cp -a /cdrom/ ${mountpoint}/knx402
 ls -la ${mountpoint}/knx402/KNOPPIX/KNOPPIX

# create /mnt/hda1/boot/grub/menu.lst
cat <<eof > ${mountpoint}/boot/grub/menu.lst
timeout=5
default=0
title Knoppix 4.0.2 from ext2 hda1 ISO scan ramdisk=32MB
  kernel ${grub_partition}/knx402/boot/isolinux/linux ramdisk_size=100000 \\
    init=/etc/init lang=us apm=power-off vga=0 nomce quiet \\
    fromhd=${partition} knoppix_dir=knx402/KNOPPIX config=scan \\
    home=scan ramdisk=32768 noprompt noeject -b 1
  initrd ${grub_partition}/knx402/boot/isolinux/minirt.gz
  boot
title Memory test
  kernel ${grub_partition}/knx402/boot/isolinux/memtest
eof
wc -l ${mountpoint}/boot/grub/menu.lst

# unmount hda1
 umount ${mountpoint}

# boot from the HDD

 reboot

v2 - include a PDI
create a pdi on /dev/dha1.  So far, booting with this PDI hasn't worked.  Looks like theres a bug in /etc/init.d/knoppix-autoconfig.  The code has two RegExs for ext3 and none for ext2.  The solution is to boot using the -b cheatcode, modify /knoppix-autoconfig, and continue booting.  Then the PDI is recognized and mounted.
