XP, Vista and 7 Triple Boot


I've got Windows XP Pro and Vista currently installed, each OS on a separate hard drive (and both 32-bit). I'm using EasyBCD to dual boot, and everything works great. Now I want to add Windows 7 64 bit (I don't want to get rid of either XP or Vista until I'm comfortable with 7), I'm going to install a 3rd hard drive, and install Win7 on that. Do I have to do anything first with EasyBCD? I'm hopingt Windows 7 install will automatically place an entry in the existing BCD, and everything will work fine, is that correct?
Windows 7 setup should do everything automatically. If it doesn't, use EasyBCD from within Windows 7 after setup.
