bootdisk for clusterknoppix

Is there a linux bootdisk available that tells the system to boot using the img file on the CD? I'm trying to boot clusterknoppix but the img file that's provided on the CD is too big to fit on a floppy.

Thanks in advance!

You could probably make you own boot disk if you know various parameters like where chain.b and all boot* files are along with where the img file is. Here is a small howto that I use to make a boot disk for system.;

Creation of a floppy with LILO on MBR:

Lilo is the "Boot Loader" for Linux which typically resides on the MBR of your hard drive. This may easily get wiped out on a multiboot system where a re-loading of the Windows operating system will reload the MBR. If the MBR is overwritten and LILO removed, there will be no way of booting to Linux. Thus it is wise to have a floppy with LILO residing on the MBR of the floppy which can point the system to boot off of the Linux kernel residing on your hard drive. Here is how it is created:

fdformat /dev/fd0 # Lay tracks on new diskette
mkfs -t minix /dev/fd0 # Create minix file system on floppy
cp -p /boot/chain.b /floppy # Copy chain loader
cp -p /boot/boot* /floppy
lilo -v -C /etc/lilo.floppy # Install lilo and the map onto floppy

Note that LILO sets the MBR to the settings as defined by the configuration file /etc/lilo.floppy.

Sample file: /etc/lilo.floppy
boot=/dev/fd0 - Floppy drive (Location of Lilo boot sector)
map=/mnt/floppy/map - Locations on hard drive where the kernel can be found for boot
linear - Specific to SCSI configurations
timeout=50 - Give the user time to decide (number of seconds) if there are multiple choices
image=/boot/vmlinuz-2.4.18-k7 - Boot this Linux kernel. This depends on your release of the operating system.
root=/dev/sdb6 - System instructed to boot from this drive. It is unique to your system. It could be /dev/hda4, it depends on your installation.
initrd=/boot/initrd.img-2.4.18-k7 - This is specific to systems using SCSI hard drives. This line is omitted for IDE.


Actual kernel name and version will depend on your Linux release.
Most of the information for /etc/lilo.floppy should be copied from /etc/lilo.conf
Actual names for the files to be used may be seen in the directory /boot
The file initrd-2.2.17-14.img is required by systems using modular SCSI support.
It is generated using the command: mkinitrd /boot/initrd-2.2.17-14.img 2.2.17-14
and should also be copied to the floppy.
