A rescue image made with "grub-mkrescue --diet -o grub.img" and booted as a cd can load a kernel and ramdisk from the CD.

When converted to a floppy image: cat grub.img /dev/zero | dd bs=1024 count=2880 of=2880.img
it cannot load files a CD inserted into the drive but only floppy or hd.

I wish to from floppy and then boot a CD - but not using a chainloader; I need to pass specific kernel options.

Can grub do this?

I decided to use kexec-loader, a small linux kernel loaded from a floppy which then uses kernel device drivers to load the next-hop kernel and ramdisk
