I'm aware of the floppy emulators that are installed to 3.5" bays where "disks" are stored on a flash drive. But what I need now is the opposite - essentially a USB dongle that emulates the floppy drive hardware with a disk inside. Something that older OS installers would recognize.
The need came up when I tried to install Windows XP on a laptop. The only way to load the AHCI drivers is via a floppy drive. I have a USB floppy drive, but no disks at the moment :( and obviously there is no 3.5" bay to install the typical emulator in a laptop.
I know I can always just buy some floppies, and in fact I have some on the way, but given the reliability of floppies over time, I still feel that what I'm describing would often come in handy.
Does anyone make/sell these?
