The only drive I do have that works is in the other half's PC. God knows why she wanted one. Another way of doing it is to put the floppy image onto a USB stick (or other mass storage device) and then use SYSLINUX to boot the image with memdisk. I used to do this at one of the places I worked at where they had about 5 different models of Dell PC which often had various different revisions of BIOS. It was handy enough to just stick the different BIOS versions on in different disk images and I could select which image to boot from (assuming that the machine would support USB booting, which IIRC they all did).
