    Just seems to be odd you can browse though your C drive but not flash off it thats all.

    The application (the flashing tool is dos) will not work without FAT32 - the wrapper that you navigate the USB stick with is able to read NTFS formatted drives.

    Hope that helps.

    I was able to Buy EZ Flash IV from a US seller zercath on Ecrater.com, As of 2014 Ebay does no longer allow the sale of EZ Flash IV carts or any Flashcarts, You could check that seller out and see if he still has any for sale,I received mine from this seller in a few days for a great price, good luck http://zercath.ecrater.com

    Hello

    Why would anything need to be purchased to flash the UEFI. Follow the instructions in the motherboard's manual and there will be no issue with EZ-Flash.
