lilo

[Samson . Pynadath]

         Now my linux installation(red hat) is over and works well but when
it boots it prompts LILO: there we have to type which os we want to boot
but I set the default as linux here the problem is it prompts only for a
few seconds withinwhich if I don't type dos  it automatically goes to
linux.I want to change ther time it prompts how to changeit
