Creating a boot floppy

[piltdown]

I have 2 hard drives, one with Windows XP installed and the other is
empty, ready to install Ubuntu. I don't want to alter the MBR on the drive
that has Windows on it - I want to leave it untouched. I would like to
create a boot floppy so that when I want to use Ubuntu I simply boot from
the floppy disk. 

Is this possible? If so, can I create one during the install process?

Thanks.
