I'm trying to update my MSI MS 7740 (H61MA-E35 B3) BIOS (currently installed version is E7740IMS V1.2) to the latest version using the archive rar file provided by SVET (much appreciated). I got as far as running MEMTEST and no errors found there. I proceed to update and get a warning about not having enough flash memory. (See the attached picture) The USB is 2GB but somehow the warning says it's only 4096kb. I tried a different USB stick and different ports, but no luck. What can I do?
