#2 Map ISO Image as CD Drive

[Anonymous]

Similar to what has been done for floppy disk images
and hard drive images, extend the GRUB map command to
permit mapping of an ISO image file as an optical (CD
or DVD) drive. This should then permit booting from
ISO images without having to burn ISO images on CD's, a
feature particularly useful when creating and testing
many ISO images.

Example:
map (hd1,1)/bootCD.iso (cd1)
map --hook
root (cd1)
chainloader +1
boot
