Multi-Boot Win. XP Pro. (SP2)

Hi,
I want to modify the boot.ini file in Win. XP Pro. (SP2) & Win. 2000 Pro. (SP4), & the file for Linux RedHat 9 to allow multi-booting.
Win. XP (SATA), Win. 2k (IDE) & Linux 9 (IDE) are all on separate HDDs. At the moment I have to select from BIOS.
Linux 9 is not yet installed, but would like the option under the Windows Boot Menu.
Also, which is “better” LILO or GRUB?
Any assistance will be greatly appreciated. Thanks in Advance.
