Cannot boot floppy drive

When I attempt to boot up with the floppy drive plugged directly into the motherboard, I get a "Floppy drive error (error 40)" after the hhd boots up normally.

I noticed that there is a pin missing in the mobo's floppy drive port, so I set the cmos floppy a drive to none and plugged in a i/o card.  When I have the I/O card in the slot and have the a drive set to 'none' in the cmos, I get:   I/O conflict 378 3f8

What does this mean?  

Is there some way I can remove the I/O conflict when the I/O card is in?  I'm pretty sure the floppy drive is still in good working order...the light comes on during boot up.  Could the floppy drive itself be bad?

Does the fractured floppy drive pin totally screw up the mobo?

The fractured pin only screws the slot, not the whole mobo. The conflict sounds like your using a shared slot for your card. Check ur mobo manual to find which slots are dedicated and use one of those... Also try checking the drive with another computer to see if it's still operational.

I/O conflict 378 3f8 is a Com port 1 address conflict, caused by the I/O card you installed conflicting with the onboard Com port. The center pin on the top row of most floppy controllers is missing, so I doubt that has anything to do with your problem. Either your cable is bad, or the drive is bad, or both. Troubleshoot with a known working cable and drive from another PC.
Missing pin on the mobo floppy slot is not unusual (usually the 3rd one from the right, notch side).

Sounds more like a cable (bad or plugged backward) or drive problem. Try the drive on another system or another drive on this one and make sure the red strip is on the number 1 pin on the floppy.

Hmmmm....Did this work at anytime?

Still typing too slow.   : /

I'm looking at 3 mobo's right now, and they all are missing the 3rd pin. The IDE's are missing the middle pin.
There is a general failure of the floppy disk drive.
This generally means either an error message appeared at boot time saying that the floppy drive failed, or other symptoms and analysis has led you to believe that the floppy drive may have failed.
Normally the controllers won't go bad so in most cases it comes down to a new FDD.
Invest $5 for a new one.
Remove power.
Remove the I/O card.
Reset your CMOS.
Attach the FDD to the controller port, using the connector beyond the twist in the cable. Verify red stripe towards pin # 1 on port.
Connect FDD power.
Start up and get into BIOS setup.
Set FDD type to correct settings (1.44 M 3.5", presumably).
Save settings and exit BIOS setup.

Does the error still occur?
There is an apparent failure of the floppy disk drive

Explanation: There is a general failure of the floppy disk drive. This generally means either an error message appeared at boot time saying that the floppy drive failed, or other symptoms and analysis has led you to believe that the floppy drive may have failed. Failure usually means that the disk is not accessible or usable at all and does not respond to any attempts to use it. If the floppy drive is usable after booting the hard disk but just will not boot, look here.

Diagnosis: There are many different causes of apparent floppy drive failures. Floppy drives are very simple affairs and outright failure is quite rare--even in old drives. Most of the time it is simply a matter of incorrect installation or configuration.


    * First of all, if you have just installed this drive or have done any other work within the PC box, check this troubleshooting list of common problems.
    * Check to make sure that drive has power. Check the power connection to the drive. If possible, try a different power connector.
    * Make sure that the cable running to the floppy drive is connected properly and is not loose or crimped.
    * If you are just installing this floppy drive, make sure you don't have the cable connected backwards. It is easy with many 3.5" drives to connect the drive backwards because the cable is keyed but the connectors aren't always. Also, don't assume where pin 1 is on the drive, since this tends to vary with different hardware. If the drive's activity light comes on as soon as the PC is booted and stays on, solid the whole time the PC is on, this is a dead ringer for a floppy cable that has been connected backwards to the drive.
    * If you are using two floppy drives then you should try to debug them one at a time, otherwise they may conflict with each other and make debugging more difficult. If two drives work separately but not together on the same cable, this usually means you are either using the wrong kind of floppy cable (make sure it has a twist in it) or one of the drives has had its jumpers changed from the default.
    * If your floppy cable has five connectors, remember that these are in two pairs of two connectors (each pair being a pin header connector and a card-edge connector, to allow you to connect to either type of drive), one on each side of the twist in the cable. You cannot use both connectors on the same side of the twist in the cable. The A: drive is the one after the twist.
    * Make sure that the floppy disk controller is enabled in the BIOS setup.
    * Check the BIOS setup and make sure that the correct drive types are selected for the A: and B: drives. Choosing the wrong type of drives can cause a failure to be reported.
    * If you have a 5.25" drive that is not working, check the drive for physical interference. These drives are large and I have seen problems like cables hanging down into the mechanics of the drive and impeding its operation.
    * If you cannot get the drive to work, the best way to check it is to swap it with a similar drive in another PC. If your drive works in the other PC but its doesn't work in yours, then you likely have a configuration problem. If the opposite happens then your drive is either bad or misjumpered. It is often easier and cheaper just to get a new drive.
    * You may have a problem with the floppy disk controller. Try troubleshooting it here.

If you dismounted the floppy drive and also changed the BIOS settings then also checkout that you have removed the floppy cable from the motherboard. By the way if you are talking about one missing pin in the location where you insert the cable then that's the way it is. One
pin actually never existed there. Checkout again and if you're not sure then checkout with some other floppy drive. It should be fine.
I think way12go deserves some points just for the amount he has wrote, even if he is totally wrong, lol!

He wants an answer, not an essay. :)
Here is my own problem that no longer exists. Not exactly. It still is here and the link is below.
