Bootdisk + lilo prompt help ..

[^Mr^]

i've just installed redhat5.2 and at the end of the installation ,
it prompted me to create a bootdisk , so i selected yes  , and it
created a bootdisk ..
when i booted using the bootdisk , it would show a lilo prompt for
10 secs where i could type linux single if i forgot my passwd
.. somehow , i've lost my bootdisk , and i use loadlin from dos ..
. how can i create the exact bootdisk that'll have a lilo prompt ?
