which grub to edit?

[Thufir]

pardon if I posted this before.  I was working on grub last night.
Win2k and Fedora 7 are on sda (hda) while FC3 is on sdb (hdb).  The
MBR on sda is being used, I believe.

Which grub do I edit to get all OS's booting?  I tried a few
variations, mucking with the one in /boot/grub/... from FC3, but
wasn't able to hit on the correct combination.
