IHMO this would be the best solution.
Step-by-step setup would be:

* Boot Knoppix from CD

* loop-mount the boot floopy image from CD and copy kernel and
  miniroot.gz to /home:

  mount -t vfat -o loop,ro /cdrom/KNOPPIX/boot.img /mnt/test
  cp /mnt/test/vmlinuz /mnt/test/miniroot.gz /home
  umount /mnt/test

* Create a small ext2 partition for kernel, miniroot.gz, /dev and
  /etc (for EXAMPLE /dev/hda5, size 8MB):

  [use parted, cfdisk or whatever to create the partition]
  mke2fs -i 1024 -m 0 /dev/hda5

* Mount the partition and copy the necessary file to it:

  mount /dev/hda5 /mnt/test
  mkdir /mnt/test/dev /mnt/test/etc /mnt/test/boot
  cp -a /dev/hd[a-h]* /mnt/test/dev
  cp -a /boot/*.b /home/vmlinuz /home/miniroot.gz /mnt/test/boot

* Create lilo.conf:

  cat <<EOF >/mnt/test/etc/lilo.conf
  boot=/dev/hda5
  prompt
  timeout=50
  image=/boot/vmlinuz
    initrd=/boot/miniroot.gz
    append="ramdisk_size=100000 init=/etc/init noapic apm=power-off hda=scsi hdb=scsi hdc=scsi hdd=scsi hde=scsi hdf=scsi hdg=scsi hdh=scsi vga=791 quiet"
  EOF

* Run LILO in a chroot environment:

  lilo -r /mnt/test

* Unmount small LILO partition:

  umount /mnt/test

* Create linboot.img file for including into NT/2k boot loader and copy
  it to floppy disc:

  dd if=/dev/hda5 of=/tmp/linboot.img bs=512 count=1
  mcopy /tmp/linboot.img a:

* Boot NT/2k, copy linboot.img from floppy to c:\ and make the
  appropriate entry in c:\boot.ini

Beware, all untested! :)

bye,
  Chris
