I'm trying to update the BIOS on my Acer Aspire S7, which is only running Ubuntu 12.04 LTS (no Windows), so that its fan would stop being so noisy. I followed the instructions on this person's post.
Specifically, it is an S7 391 and I was attempting to download BIOS version 2.18 which was described as "Improve thermal performance."
I ended up having the exact same problem:
C:\> FLASHIT.EXE ISFLASH.FD
Insyde Flash Utility for InsydeH2O
Error: This ROM file size isn’t correct.
Error: ROM size: 4728c0 Current BIOS size: 100000
I read somewhere that this was often caused by an incorrect BIOS, but I know for fact I have downloaded the right one. Does anyone have any suggestions? Thanks!
ISFLASH.FD
file appears to be an EFI executable, and can't be flashed directly like that. The expected size is0x100000
bytes (1 MiB), while the file you got has0x4728c0
bytes (~4.45 MiB).
