This is a little bit like trying to hit a triple bank shot into the side pocket I guess (i.e.- a long shot), but is the floppy a usb 1.1 device? Check USB device support in the bios and make sure support for legacy devices is enabled. Nice mobo! - I almost bought one. Decided to wait till summer to upgrade.
If you are overclocking, go back to stock on everything and see if that fixes it. I'd try a different brand new floppy disk too.
All in the BIOS is good; there isn't much difference between this and the Maximus Extreme III or IV; just bells and whistles I never used anyways. This is the truth: without realizing it I upped the bckclk to 145 and CPU (i7 1366 970) ratio to 25, 12G [6*Corsair DDR3, 2000MHz 6GB (3x2GB) 8-9-8-24DOMINATOR GT] to 2000mz, 8-9-8-28 so that the system actually booted up no problem to 4.25G; scared the s**t out of me-and on air! I immediately rebooted back into the BIOS and am now running 3.35G, 25, mem at 1600mz 8-9-8-24. I'm not bragging; just trying to illustrate how solid this mobo is. It is really that good....and the Corsair GT Dominator is fantastic RAM.
..not so much although I like to have all my options; I mostly slipstream any drivers now and I use the ASUS update utility in the BIOS to do that, but, I use Terabyte for all my imaging/backup etc. and their apps are all very small, drive level; not worth a USB stick. Also, I have all my training records stored on floppy and want to transfer them using my computer. Mostly, though, it just really bugs the hell out of me when something doesn't work when it should...ya' know!?
Unfortunately, none of the OC thing worked and this is the only USB floppy in existance anywhere close, plus, it works fine on another system.
64 bit Win 7 doesn't support DOS system anymore, but 32 bit Win still works. That may be the reason why your floppy drive fails, I have thrown mine already!!!
I figured out the problem for read/write to floppy capability (on my system anyways)-Program Compatability Engine and Program Compatability Assistant must be turned on, I had the entire service disabled because I do not use any "old" apps and have had no concerns at all with any games or software/other hardware etc., so, I've been running with it turned off. The format problem still exits-I cannot, for instance, create a bootable floppy or install any of Terabyte's software to floppy. I believe the root of the format concern will be in that I am running RAID 0 and Win 7 loads up the sfloppy driver-SCSI-instead of the standard floppy.sys. I am not going to delete my RAID array just to prove that point. It is enough for now that I can read/write so I can get my tax and training records transferred...Also, on cold boot the BIOS hates it even though it recognises it correctly.
