Help, please! I am so far out of touch with the new hardware! I want to install a floppy drive internaly into my machine. There are 2 SATA controllers available but there are also 4 f usb ports (?) which seam to have 4 pins each! I can't seem to find any info on the f usb ports, ie: as to what they are. If I am not mistaken I can buy an internal floppy drive that has an SATA intreface, but I can also buy an internal floppy with a usb interface. What I need to know is just what is the f usb port and is it the correct on for use with an internal usb floppy drive? Or can someone point me to some information place on the web that will inform me (with pictures) just what an f usb port/interface is! TIA


Software gives me a headache.

There are no sata connectors for floppy drives
If you want to install a floppy drive you will have to make sure you have a port for it on the motheboard as newer ones are doing away with this type of unit.

floppy drives have a ribbon cable something like the old ide cables that were used on hdd and cd-rom drives etc
You will have to make sure your power supply has a floppy power cable as well

usb is for external devices mostly unless you are on about the usb headers on a mobo

HP Pavilion a4316f Desktop PC - support

Motherboard Specifications, M2N78-LA (Violet6)

* Motherboard manufacturer's name: Pegatron M2N78-LA
* HP/Compaq name: Violet6-GL8E

"...Pegatron is a division within ASUS. ASUS is spinning-off Pegatron completely and will be a separate company (partly owned by ASUS) that does the actual manufacturing. ASUS' branding will still go on the products that are marketed by ASUS, but not the products that Pegatron supplies to OEMs such as HP."

I see your mboard has no legacy floppy data header. Bogus.

I have never come across an internal USB connected or SATA connected floppy drive; the former might exist; I very much doubt that the latter exists. There is no such thing as a cable or adapter that connects a legacy floppy drive directly wired to a USB port connection - there has to be additional circuitry in between the two.
You could use an external USB connected floppy drive, but they cost at least $40 or so.

The F USB headers are probably the same as on Asus mboards - for two USB ports - and wired up the same way as for Asus mboards.

F probably stands for Front ?

Pin 1 is on the 4 pin side, on the other end from where the pin is missing.
In that 4 pin row, from pin 1, +5v, Data 1 -, Data 1 +, Ground
In the 5 pin row
The pin beside pin 1 is +5v, Data 2 -, Data 2 +, Ground, no connection to the fifth pin.

Each row is for one USB port.

You have two F USB headers, not four.
Use something to magnify the printing on the mboard if you need to.
NOTE that there is a F 1394 header - it has the identical pin layout as the F USB headers, upside down - DO NOT connect USB port wiring to that, or firewire port wiring to the USB headers - doing so will damage whatever you plug into the mis-wired ports in a very short time, and can damage mboard circuits as well.

OK thanks to tubesandwires I have discovered that the F USB connectors on my mobo are Front USB headers used to connect additional USB ports to the system. Instead of the USB PCI card that I am currently using! Cool! Thanks all!

You're welcome to use our help.

Are you going to get an external floppy drive, or what?
