bootable floppy for dual boot

I partioning a hard drive into sections and installing a different one on each. For example, WINME, WINXP, ETC. I want to create a bootable floppy that will give me the option of what operating system to boot. I thinking that autoexec.bat is my best bet. but I heard XP doesn't use it. The thing is that when it boots up off the floppy I want to be able to end a string a characters at the command line. Then the program does a simple caluclation to determine which OS to boot able.

Any help would be helpful.

Thanks,

AAron
