lilo.conf
 

I`ve made a raid (1). I have 3 partitions md0, md1 and md2. md0-/boot, md1-/root, all is working fine, but I must put some corrections to the lilo.conf. I know where it must be, but I can`t find it... /etc/lilo.conf... I can setup lilo.conf at linux setup process, but if I didn`t do that, how can I find it after installation is complete without installing "lilo"? Please help me.

You only have lilo.conf if you have installed lilo. It should in most cases reside in /etc. Seems you haven't created one or lost it?!
You can try to find it (or any other file) with for example "locate lilo.conf" or
