HD Install :: fix grub

I have a DSL HD install that I've tweaked and have working very well. I love it. I put Fedora Core on another partition to check it out and it seems to have wiped out my grub entries for dsl. I have a dsl entry but it no longer resembles what it used to. Says something about chainloader+1. Anyway, what i want to do is edit this entry to boot up DSL. I can't figure out the command(s). Lastly, where do I go to fix grub? Will menu.lst be on the Fedora partition or DSL partition?
Thanks.

probably the Fedora install wiped out the grub menu.lst and added it's own. So you will find the one to edit in whatever is the new /boot/grub directory. The chainloader is normally what loads the bootable primary partition that Windows is on if you have a dual boot with Windows.
