It looks like I need to add to and rewrite to my /boot/grub.conf file.
I am new to Linux and
just want to be sure. My boot sequence starts with the floppy but I
don't know how grub decides which file to read.

I tried the rescue cd to see what the fc5 /boot/grub.conf file says
but I am new to the command line and could't bring it up.

can anyone help me?

thank you,
