The syntax is different from Lilo's and so to scratch my own itch I'm creating this quick reference.

It will automatically create a /boot/grub/menu.lst file for the kernels in /boot/. It will also append a manually configured set for other partitions like the GNU/Hurd. +* grub-floppy is a **Debian specific** boot floppy creation script. +* mkbimage is a **Debian specific** boot disk image creation script. +* <http://khazad.dyndns.org/packages/grub-disk/> contains a Debian packaged makefile for creating CD & floppy images. Looks like it doesn't work properly. If you fix it, please send patches to the maintainer. +* essential GRUB commands & disk syntax + * root + * kernel + * module + * boot +* sample file + + title GNU/Linux + root (hd0,11) + kernel /boot/vmlinuz-2.4.18 root=/dev/hda12 ro + initrd /boot/initrd.img-2.4.18 + savedefault + + title GNU + root (hd0,15) + kernel /boot/oskit-mach root=device:hd0s16 -- + module /hurd/ext2fs.static \ + --multiboot-command-line=${kernel-command-line} \ + --host-priv-port=${host-port} \ + --device-master-port=${device-port} \ + --exec-server-task=${exec-task} \ + -T typed ${root} $(task-create) $(task-resume) + module /lib/ld.so.1 /hurd/exec $(exec-task=task-create) + savedefault + + title DOS + rootnoverify (hd0,0) + chainloader +1 + +-- [[Main/GrantBow]] - 01 Oct 2002 <br /> -- [[Main/GrantBow]] - 22 Dec 2002 + +Another example, just as good, but a lot easier to read.
