Triple boot FC3 intallation question

[Bob Brennan]

I have a Pentium III PC with Windows ME and Win2k Pro currently
dual-booting. For reasons not important to this question I want to
keep both current OS's and add FC3.

I am well practised in setting up the proper partitions for such an
installation but am wondering in advance if anyone knows if all 3 OS's
will now be available in the FC3 boot loader, which I usually choose
as the default Grub loader.

Thanks in advance for advice / warnings.
