    Hi, (I hope not to be offtopic)
    Should I reprogram the chip in the bios of an asus x53sv with a programmer because the chip is damaged, but as often happens, the extension of the file that I downloaded from the site is not in ROM or BIN but ends with a number. In the past I changed only the extension but now, seeing the size of the file, this is not how it should be. How can I convert this file into a BIN or ROM file?
    for example
    This is the file K53SVAS.208 size 2,560 KB but the chips have 4 MB capacity.
    in another model asus X53U the file K43BY.211 have 2048 KB and it's ok because the chip have the same size.

    Just flash it at the end of the chip. The first part of the chip probably contains the ME firmware, which is not updated and so is not present in the bios image.

    Edit: Oh, I just noticed that you say the chip is damaged. In that case you may have to find another laptop of the same model from which you can dump the ME part.

    (OP)
    :)Hi, confirm that the tool has generate a correct bios .rom file. (eset see the tool as good but norton delete it as trojan) I programmed the bios chip (after desolder from mobo and resolder) an all work fine.
    I think that this procedure delete or change a win8 key. Anyone can help me to check if a win8 key is present ?
    another problem is that the serial number of the card, the mac address, and other information shown on startup are different from the label on the notebook, with the hp I use a tool that allows you to restore this information, I do not know if there is a tool for asus. it is possible to identify the memory location on the bios and manually edit the file with a hex editor?
