One nifty use of the floppy controller is for chain-booting. If you're building an application to instrument the process of creating a VM and installing an OS on it, chain-booting off the (virtual) floppy is often the best choice. I'd be happy to replace it with a programmatic API to control the boot sequence from outside the VM :-).

5 1/4" were 160kb when single sided DD, and went to 320kb when you notched then (double sided DD). Later they went to 1.2MB when they went to HD capacity (DD = double density, HD = high density).

Cheers,

Ben

Eli Juni -

Hyper-V has a programmatic API to change the boot order in the BIOS - if this is what you are looking for.

Cheers,

Ben

Never get rid of the floppy controller. We use it for shuttling CRLs from our offline Root/Interm VMs to the prod Sub Auth VM.

Very handy and quick!

I use a vfd to store the answer file required for a Small Business Server 2003 to Small Business Server 2008 migration install.

Copy protection. There are still applications out there (Rockwell Software is the biggest offender) that rely on installing a key from an oddly-formatted floppy disk.

The floppies I used most were Commodore 64 - a whopping 170K, doubled by using the notcher tool!

The VFD can be used to fill in the GAPING hole known as a virtual router... Nothing more simple than you build a Brazil Router on a VFD to enable routing between the various VLANs... Beats the heck out of building a full fledge server to host a simple routing device.

I still don't understand why you won't allow connection to physical floppy disk. Couple of useful scenarios

1. Add special driver (F6) during XP install as Hyper-V guest

2. Like another reader pointed out, Rockwell is another
