Gee, now that you've jogged my memory (it takes a few slaps
up-side the head now and again) I seem to remember you can do
the same with the RedHat rescue disk. You give it the command
"linux root=/dev/hda?" at the boot prompt. Personally, I've
just taken to making copies of the boot sector with "dd
if=/dev/hda of=/dev/fd0 bs=512 count=1". You just pop in the
floppy if something goes wrong and usually your right back in.
I keep an "emergency" LILO boot for my current kernel (it saved
me hours a few hours a couple of months ago when my boot sector
mysteriously got corrupted) as well as a couple older LILOs for
accessing old kernels when I upgrade. You can do the same to
save off DOS/WinNT boot sectors during a new installation of
Linux by switching VTs soon as the install boot image has
loaded.

I have one other suggestion to offer, which I use every time I
have to reinstall Windows (every six months or so). If you
download a suse boot disk image, write it on an msdos formatted
disk, and boot from it, thwere is an option under "Start
Installation" to "Boot installed system". You have to specify
the root partition, and it runs INIT, on the kernel already
loaded from the floppy. That gets you in to what's left of your
system. The rest is up to you ;-). Typing "lilo" will restore
the boot record. If more than that is gone, you're on your own.
Try under www.suse.de or www.suse.com
