	From my experience the method you've described is the easiest way
provided you have a DOS boot disk with fdisk on it handy... As for a Linux
way to do the same... Speaking from Debian-ville, when you install LILO it
makes a copy of the the boot sector and stores it in /boot as
boot.<Major><Minor> so my boot sector for my first partition on my first
IDE drive is stored as /boot/boot.0301... If memory serves me right you can
copy this back to the drive using dd if you know the right command line
options... The file itself is 512 bytes...
