    I was installing bios updates on my vaio when it froze and then stopped working and now I have nothing on the screen when I power it up and I am stuck. I have the Rom file and I have tried putting it on a usb and a dvd and pressing the ctrl + home button and it didn't fix it. I tried using floppy but the .Rom file is too large for the floppy disk and I am wondering How I can fix this

    So can I rename the .rom file to anything with .fd at the end? Also I tried a floppy drive but the .Rom file I have is 2 mb and the floppy disk is 1.44 mb

    the main problem is if bootblock works or not.
    best is to get CH341A programmer and thats if its SPI type soic8 clip. its a TSOP40 chip i think..so not SPI..

    where to find a copy of the chip .bin dump hmm i looked and i see its not SPI so nobody has a copy.

    try to make a backup of bad flashed chip to backup.bin post it and we can try to fix it in hex editor with the .rom by comparing

    fist identify bios chip, i think its TSOP40

    from what i see youll need to make cd with recovery.. if bootblock is ok.

    im not up to par with sony bios recovery so im not much help with it..

    otherwise you are out of luck if its not SPI chip type wont be easy.
