This is the summary:
GRUB for DOS is a build of the GNU GRUB boot manager for DOS, and can be run under real mode DOS. It also has many new features. For example, it can be booted through BOOT.INI of Windows (grldr) and kexec of Linux (grub4lin). The disk emulation feature is another enhancement over GNU GRUB, and can be used to run legacy DOS/Windows9x systems with floppy or hard disk images.
