You can stick GRUB on a floppy to boot, but it's much simpler to use mkbootdisk.
I am not looking for the easiest way, but the most elegant way.

That will build a bootable ISO image you can burn to CD using your favorite CD burning utility.
Making a GRUB bootable CD is no problem at all. What I can't get to work is installing GRUB on another medium, like floppy and harddisk, and then, after the system has booted into GRUB, being able to access a kernel and initrd that reside on a cd/dvd.
I would like to use a grub.conf like this:
---------------------------------------- grub.conf -------------------------------
default 0
timeout 10
title My Linux on harddisk
root (hd0,0)
kernel /vmlinuz ro root=LABEL=/
initrd /initrd.img
title My rescue on CD
root (cd)
kernel /vmlinuz ro text rescue
initrd /initrd.img
------------------------------------ end grub.conf -------------------------------
If I make a CD bootable grub with stage2_eltorito from grub-0.95, the (cd) directive is available. If I install the stage2 from grub -0.95 on floppy or harddisk, the (cd)-directive is not available. Further I can't find any documentation on how to incorporate the iso9660_stage1_5 image in the boot system.
I found a message describing the command to use in the grub shell is:
install (fd0)/stage1 (fd0) (fd0)/iso9660_stage1_5 (fd0)/stage2 p (fd0)/grub.conf
In this example all the stage files where installed in the root of the floppy filesystem.
Following this I had a floppy that after booting wrote the word "GRUB" to the screen endlessly.
Should I just replace stage2 with iso9660_stage1_5 in the install-command?
Any help is welcom.
