Go to /boot and do a ls. You should see a vmlinuz-2.0.34 (or whatever your kernel version is). This is your bootable kernel image. Put a dos formatted floppy in your drive and type
      dd if=/boot/vmlinuz-2.0.34 of=/dev/fd0  
this will dump the kernel to the floppy and your system should boot from it. Try it out and if it works make as many as you want. You can also use mkbootdisk from within redhat.
Make sure your floppy disk has no bad sectors

i have a problem . i made the boot disk as you said but i have the following problem :
The computer reads the disk for bootup , loads it , starts booting Linux but then says:
Kernel panic and something for a mistake in partition or something like that . i suspect the kernel image is not the correct one  ... what do i do ????

You can also use the floppy to just 'boot' with loading the kernel still from the harddisk, a bit faster.

If you in /etc/lilo.conf enter:

boot=/dev/fd0
root=/dev/<where ever your root partition for linux is located>

Then you can list the images you wan't to chose from at boot time... if you need help with this gimme a howler.

Then just run lilo, with a floppy in the drive, and GO! =)
