I was wondering if you could use a virtual floppy disk as virtual media through, in this case, the Dell Remote Access Controller (HP calls it iLO).  I downloaded the virtual floppy utility found below and used the virtual floppy as virtual media to upgrade the BIOS on a Dell PowerEdge 2950 server.

Don’t know if anybody cares, I don’t even know if I care, but if you ever need a virtual floppy disk for Windows, it’s there.
