This is an explanation on how to make two floppy disks to boot.

Also see: [[Ce Bit]]/

Boot Knoppix on a machine where it works from CDROM. Then execute these commands to create two floppies. Leave out the "$" when entering the commands, the "cat" commands goes over several lines, down to EOF, in between is what the file /mnt/floppy/boot/grub/menu.lst should contain afterwards.

#Floppy 1: grub + kernel
$ mkfs -t vfat /dev/fd0
$ grub-install --root-directory=/mnt/floppy /dev/fd0
$ cp /cdrom/boot/isolinux/linux24 /mnt/floppy/
$ cat >/mnt/floppy/boot/grub/menu.lst <<EOF
default 0
timeout 3

title Knoppix Floppies initrd
kernel (fd0)/linux24 ramdisksize=100000 init=/etc/init lang=ch apm=power-off vga=791 nomce BOOTIMAGE=knoppix
pause Insert floppy with miniroot and press ENTER
module (fd0)/minirt24.gz
EOF

#Floppy 2: miniroot
$ mkfs -t vfat /dev/fd0
$ cp /cdrom/boot/isolinux/minirt24.gz /mnt/floppy/

The Kernel 2.6 does not fit on the same floppy as GRUB. In that case, copy the initrd26.gz on the boot floppy with grub and the kernel on a separate floppy.

the menu.lst file will then look like this (noscsi added):

title Knoppix Floppies initrd
pause Insert floppy with kernel (disk 2) and press ENTER
kernel (fd0)/linux26 ramdisksize=100000 init=/etc/init lang=ch apm=power-off vga=791 nomce noscsi BOOTIMAGE=knoppix
pause Insert floppy with miniroot (disk 1 again) and press ENTER
module (fd0)/minirt26.gz

Obselete Document:

You make a KNOPPIX Boot Floppy by one of these procedures.

!It is not correct to just copy files onto the floppy.

• !!If you have KNOPPIX or a other linux distribution started:
  

Insert an empty, formatted floppy disk and the KNOPPIX CD.

K --> KNOPPIX --> Root Shell --> cd /mnt/cdrom/KNOPPIX --> ls

Now you should see a file name boot.img .
In some versions the file may have a language name attached.

Enter the following line from the shell:

dd if=/mnt/cdrom/KNOPPIX/boot.img of=/dev/fd0 bs=1440k

This will erase the floppy and the KNOPPIX boot disk.

Or for the lazy 

cat /mnt/cdrom/KNOPPIX/boot.img >/dev/fd0

• !!If you are in Windows:
  

Insert an empty, formatted floppy disk and the KNOPPIX CD.
Open a DOS Window, open the KNOPPIX directory on the CD.

d:

cd \KNOPPIX

create a boot floppy using the command:

mkfloppy.bat

* actual path on Knoppix 3.3 CDROM: /cdrom/KNOPPIX/mkfloppy.bat

Is this also possible in Knoppix 3.4??

At least with 3.4 2004-05-04, no. The file boot.img is not there, neither is the mkfloppy.bat or rawwrite2.exe. This might be due to the use of isolinux. I need this, badly enough to continue investigating it.

Hi, look here [[Ce Bit]]/ for a boot.img and makefloppy3.4.sh. Hope this helps. MTH

Two Bootfloppies for Knoppix 3.4

Check out the mkbootfloppy script (Knoppix->Utlities menu) thats on 2004-05-10 and newer. It wil create two bootfloppies with the currently running kernel.
