Hmm its always good idea to keep your mbr on your linux boot disk
with a quick script to recover it. You will find the saved mbr record
in /boot/mbr.b usually. Then:
Create files /root/lilo-fd.conf and /root/fixmbr:
cat >/root/lilo-fd.conf <<EOF
boot=/dev/fd0
root=/dev/hda1
install=boot.b
map=map
vga=ASK
#append="mem=128M"
delay=10
compact
read-only
default=linux
image=vmlinuz
Label=linux
image=vmlinuz
Label=fixmbr
append="init=/fixmbr"
EOF
cat >/root/fixmbr <<EOF
#!/sash
dd if=/mbr.b of=/dev/hda bs=512 count=1
EOF
Of course /dev/hda1 replace with your root partition and
I suppose you replace master boot on primary master HD.
Then insert new floppy and proceed as root:
mke2fs /dev/fd0
mount -t ext2 /dev/fd0 /floppy
cp /boot/vmlinuz /boot/boot.b /boot/mbr.b /floppy/
cp /root/lilo-fd.conf /root/fixmbr /bin/dd /bin/sash /floppy/
mkdir /floppy/dev
mknod /floppy/dev/hda b 3 0
chmod 666 /floppy/dev/hda
cd floppy
lilo -C lilo-fd.conf
cd /
umount /floppy
I'd say that creating such floppy could save you lots of troubles in case
you want to play with installing windows on your computer, since it likes
to replace your masterboot in the worst possible moments and then again
don't work/install in case you won't give it its M$ masterboot ...
