Raw image format

general
A raw image is just a simple, binary only, with no meta informations, flat, sector by sector copy of a data medium directly into a file.
grub4dos can boot those images for the real mode part. This means it's working well for any kind of DOS, Win9x and probable WinME. After the operating system switches to protected mode, rescans the devices and does try to load it's own device driver it will fail (feature request).
