What will you do if you forgot your ROOT PASSWD?
I've mounted the PASSWD file but it is in read-only mode.

How did you mount the password file?
To remove the root password to the following.

Boot Linux from disc and enter with root (not password needed). Mount the drive where the system is on. Enter the etc directory and edit the file passwd. Clear the password entry for root. Reboot your system.

I tried booting using the disc after that happened, i mounted the passwd using  mount <dev> <file/directory>, but i can't find a way to edit the passwd file -- pico, edit and joe didn't work.Is there another way I can't modify the passwd file?  is there an  equivalent function that works like edit or pico?

Start linux in singel user mode by typing
linux single
or linux 1

at the lilo prompt.
You don't need any password to start in single user mode.
Then just change youre password with passwd.

You can also try this:
1. boot from floppy
2. mount youre / partition on /mnt
3. Use chroot to change / to /mnt
4. Try vi or pico or some other editor now.
