Use an external USB floppy drive.
If you MUST have internal.... if you're good and creative you -might- be able to disassemble an external USB floppy drive and mount it like an internal drive.
Alternatively, you could hunt down an old LS-120 "superdisk" drive. Its an IDE drive (40 pin connector, like your hdd or cdrom) that reads floppies (in addition to high-capacity proprietary disks)
The short answer is that you don't unless you can find an expansion card that has a floppy drive interface on it (which I doubt you will at this point). Your best bet would be to get a USB external floppy drive. You can find them easily enough through online means and probably in a local computer store.
It is possible to get a floppy to USB cable adapter. Use this to connect to the spare USB connections on the motherboard. You may need to get a cable intended for attaching forward USB sockets.
You would have to use a USB Floppy drive. Most of these cannot be easily mounted internally, however.
if your motherboard has pci or other types of expansion slots available you can buy a expansion card that allows you to connect an IDE device to your motherboard
There are two cables that connect to the floppy drive in a desktop computer.There is a four pin power cableThere is a ribbon cable that has a part twisted end (the twisted end connects to the floppy drive).
A floppy header is the interface used on motherboard to connect floppy disk drives. They are far less common on modern motherboards due to their limited usefulness.
A "Berg" connector.
There are several uses one could have for this port. I believe the original intention was to attach the front panel USB ports (if any) to it instead of to the motherboard. You could also use this to connect a USB floppy drive (which would be faster than the legacy floppy connector), a hard drive, or even a USB Flash drive for easy additional internal storage.
Simple, easy to connect, being internal means permanently and securely available
External floppy drives use additional hardware to connect to a computer, whereas an internal floppy drive uses a simple cable to connect to components already integrated into most motherboards until very recently. Another factor is that external USB floppy drives are a seldom-used item, whereas an internal floppy drive could be leftover stock from when they were a common commodity in every computer.
Floppy connectors are used to transfer data between a floppy drive and a computer via motherboard, in order to use a floppy disk. They are very similar to IDE cables, but are a little smaller, and are exclusively for floppy drives.
a cable from the power supply to the Berg power connector on the FDD a cable from the 20-pin ATX power connector socket on the motherboard to the Berg power connector on the FDD
it is a 34 pin connector
a cable for connecting a floppy drive to the computer motherboard.
One or zero, depending on the specific motherboard model.
Mini Connector
