    I have two problems:
    Well, in first place, I have a Lenovo Z470, with a Intel HM65 chipset, and I need to access the advanced settings in the BIOS menu in order to increase my dedicated graphics memory. So, I need to mod my BIOS to unlock these options.
    The second problem is that there is no bios file to download from the manufacturer, so I took a backup from my current BIOS, but I read somewhere a backup is not good for flashing.
    If you need any more informations, I will provide them as soon as I can. I would be very happy if someone could do it for me, but I am willing to do it by myself, if necessary.
    Thank you

    What BIOS is it?
    If it is a Phoenix BIOS then you cannot re-flash the backup. You need additional data which are provided by the OEM at a BIOSupdate.
    At any other BIOS / EFI it should work to re-flash the backup (except some Intel boards, probably)....
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...
