updating gateway sx2855 bios to UEFI, size to large?

[evoker121]

i have a gateway sx2855 with a fresh UEFI install of windows 10 that i was trying to update the bios on, when i download the files from the gateway website and unzip it, its got a DOS, EFI , ROM, WIN folder and a readme doc

when i try to run the afuwinx64 program in the win folder it reads the bios file to 100% then says the file is larger than existing bios and closes the cmd window the current bios is P01-B2 and i am trying to upgrade to P11.A4,

the reason im trying to update the bios is so i can drop in a i5-2500S CPU which from what little ive found about this motherboard(its an acer-h61h2-ad), i5's with 65 watts or less will work with a bios update fine

Since the BIOS update file is compatible with Windows 7 it might not work from Windows 10.
Did you follow the any of the other methods (like updating it from DOS), outlined in the Readme file?
By the way there isn't anything related to CPU on the release notes.
