Help - FL90 Bios Corrupt!

Please help me!
I've updated the FL90's bios and now the notebook doesnt respond. When I power up, only LED's light up for 2 seconds, and then completely nothing..
Is there any way I could fix it?
I know that there is a Crisis recovery disk for HEL80 somewhere that works, does it work for FL90 too?
And I don't have currently USB Floppy drive, only USB Flash and CD-ROM, does the floppy is required?

Please please help...

 

I read somewhere that you should try booting while you're holding Fn + B. I don't know what it does, but why don't you give it a try. Maybe it'll ask you to reflash .

 

thanks but thats only the part of the recovery mode, I need for that also a backup of working bios on a usb floppy drive, and I dont have a such drive, only usb flash and cd/dvd.
Im trying to find some other solution..
Does anyone know if FL90 has a battery for cmos/bios that can be removed for 5 minutes, and the bios resets automatically?

 

Are you sure you need a floppy drive?

 

well all the information about the recovery mode mentions that a floppy is required.
I tried to test it with usb flash drive, or a cd, and they didnt work.
So I guess it needs a floppy.
Im looking for the battery thing right now, maybe it could reset bios to factory defaults. but I dont know where the battery is located in FL90, and how does it look, not to mention how to remove it..

EDIT: I've heard that the battery thing wont do anything.
I'm forced to use only the recovery mode, I also now know that usb flash wont work, theres only chance with CD and USB FDD. With cd I've tested different combinations and it didn't helped, so I'm counting on the floppy drive, but I have to wait few days until it arrives.. hope it will help
