Hello all, I have a Sony Vaio VGN-FZ31M and need to change the BIOS. I have the current BIOS (original ROM file) and also the new BIOS. Before doing anything drastic I want to take every precaution and I haven't yet found a place explaining exactly what to do should something go south. In the worst case scenario the laptop won't boot up after flashing the BIOS, so I would need to use the original ROM file to get things back to normal. Is this possible? How? I found that thread in the forum suggesting to boot from a USB stick but I can't really understand how that works or how to do it even, I am a bit of a newby when it comes to the BIOS. Does somebody know of a good place explaining how to do this? Thanks in advance!
