Thanks for the response Michael! I understand now. Just wanted to let you k= now that Hyper-V Gen2 VMs do not have a virtual FDD. Not that we have FreeB= SD supported on it yet but the scenarios you describe may not work on Gen2 = FreeBSD virtual machines today. Thanks again for the feedback.

The scenario I see the most is a virtualized (HyperV, VMware etc.) FreeNAS = guest to which you pass a PCIe storage controller card to so that ZFS is gi= ven "bare metal" access to hardware disks yet has the benefit of the fast i= nternal backplane if you will for networking, rather than going over copper= or optical network interfaces. Because the FreeNAS guest may be one among many, it would not be desirable = to reboot the whole system and boot to a floppy to apply a BIOS update to a= PCIe controller card. Again, I have not tried anything like this but it is= a possible use case of what you describe. Also mind you I never want to se= e another floppy-based BIOS again but they are still out there.
