Dell Force10 S4810 Firmware Step Upgrading

Hi all,

I recently acquired a Dell Force10 S4810 second hand and it came with a really older firmware (8.3.7.0). I would like to try and upgrade the firmware to the newest version, however I am having trouble locating the firmware and U-boot files needed for the step upgrade. I believe I need FTOS0SE-8.3.12.0.bin and U-boot.1.2.0.5.bin.

I believe I found the most recent firmwares at: ftp://ftp.force10networks.com/releases/FTOS_Release/

If someone could provide a location to the needed step upgrade firmware it would be greatly helpful.

Also, this is my first time upgrading a Dell Force10 switch firmware, so if you noticed anything wrong in the above post, please feel free to point it out.
