booting lunix on "strange" machines (using one floppy)

Boot knoppix (on a machine with a bootable CD drive).
In a console format and create the boot floppy using the following commands:
mkfs.ext2 /dev/fd0
fsck -f -t ext2 /dev/fd0
mkboot -d /dev/fd0
That doesn't work.... Too big!!!

Build a kernel small by removing and configuring most drivers as modules.
ls -lt ./arch/i386/boot/bzImage
-rw-r--r-- 1 jfclere users 835540 2005-08-01 22:40

Do the job:
mkfs.ext2 /dev/fd0
fsck -f -t ext2 /dev/fd0
mount /dev/fd0 /mnt/test1
mkdir -p /mnt/test1/boot/grub
cp /home/jfclere/KERNEL/linux-2.6.10/arch/i386/boot/bzImage /mnt/test1
cp /home/jfclere/tmp/initrd /mnt/test1
cp /boot/grub/menu.lst /mnt/test/boot/grub
cp /boot/grub/stage1 /mnt/test/boot/grub
cp /boot/grub/stage2 /mnt/test/boot/grub

menu.lst contains:
color white/blue black/light-gray
timeout 8

title linuxtest
kernel (fd0)/bzImage root=/dev/hda1 vga=791
initrd (fd0)/initrd
title floppy
root (fd0)
chainloader +1
