Change the Floppy Drive Configuration in the vSphere Web Client
You can configure a virtual floppy drive device to connect to a client device or to an existing or new floppy image.
ESXi does not support floppy drives that are backed by a physical floppy drive on the host.
NOTE You cannot use vMotion to migrate virtual machines that have floppy drives backed by a physical floppy drive on ESX 3.5 4. 0 and 4.x hosts that vCenter Server 5.0 manages. You must disconnect these devices before you migrate the virtual machine
8. (Optional) Select or deselect the Connected check box to connect or disconnect the device.
9. Select Connect At Power On to connect the device when the virtual machine powers on.
10. Click OK.
