I have saved on my webserver a "dd" image of what I call my "Grub
Emergency Boot" floppy - works well when I must reinstall my Windows
partition and it toasts Grub out of my boot record - I can use it to
boot into Linux and eventually re-write Grub to the MBR. This
image is suitable for use with RAWRITE/RAWRITEWIN, which can be found
from most Linux distribution sites.
Also included is sbootmgr.dsk, which is a DD image of a Smart Boot
Manager floppy, allowing a system to be booted from CD even when it's
old enough that the BIOS doesn't support it.
