    Hello everyone.

    First of all I need to apologize for my bad english. If this is the wrong section (I think it is) please move my thread, I just couldn't find the right place.

    It's about a "ASUS PRO5MSV" Notebook, it's mainboard is a "N53SV".

    Somehow - please don't ask, I can't tell you - I crashed the BIOS / EFI (It's a EFI / UEFI) by updating it with ASUS EZFLASH (or how it is called).
    I don't have the file I used for updating - Sadly.
    Steps done from EZFLASH:
    1. Erase > 100%
    2. Copy > 100%
    3. Verifying > 100%
    (I think it was this order)

    Then the notebook shut down and wasn't reacting at all(no fan etc.). I already tried a lot to bring it back to life without needing to take out the chip.
    1. Take out CMOS Battery (several tries, between 5 mins to 24 hours)
    2. Looked for a reset hole, but there's none (suggested from ASUS)
    3. Spammed the TURN ON button for minutes (suggested from ASUS)
    4. Put in a bootable USB Stick (but no LED blinks)
    5. A lot of diffrent key-combinations to bring it into some "writing mode"; "zombi-mode". But non of them worked in anyway.

    The mainboard get's power and also some sound (no loud beep beep, but a silence beeeeeeeeeeeeeeeeeeeeeeeeeeeeeep as long as the DC Adapter is connected, hard to explain. It's also getting "warm" (not cold anymore, but not really hot))

    Some repair-service I brought the notebook to read the chip but didn't update the EFI / BIOS since he didn't know where to place it. (4x2 PIN Chip; 32 MBit; 4 Mbyte; BIOS size is about 2,5 MByte)
    He also "read" the chip and saved the file:
    www . mediafire . com/?egl6dddtzv6odad

    BIOS from ASUS:
    www . mediafire .com/?1t0hn21papwk51s VERSION 206
    www . mediafire .com/?z6qxg0x55narh7w VERSION 209
    www . mediafire .com/?nd48re1o1qx0v5t VERSION 213
    www . mediafire .com/?w7xrmmiar6t5sd5 VERSION 214
    www . mediafire .com/?4dtqtjfo7d8m2bl VERSION 215

    There's no problem read / writing things into the chip, but as I was told it's messed up totally.
    I already contacted ASUS, but they aren't giving out the "full code", only things shown in the download tab from their page, but they aren't helping.

    I'm not sure what I'm asking in general? Can someone get a working code we can paste into that chip? Some universal - EFI?

    I'm thankful for everything that helps bringing this notebook back...

    Thank you a lot for your time and efforts in advance

    usualy with SPI programmer he dumps it and compares bios dload then merge when begining and end match. then flash that to chip.

    i seen this happen to a few asus newer boards.. bad winflash x64.
    i do dos

    test the ram as i see discrepancies that point to ram issue. (i might be wrong)

    however it uses no module compression in chip.. while bios file does
    Phoenix mod tool 2.11 says

    EFI / Insyde BIOS
    Finished Extracting
    No module compression used in CHIP.BIN

    EFI / Insyde BIOS
    Finished Extracting
    LZMA compression method used
    Recovery filenames are:

    dloaded bios.

    do u have the original Asus disk that came with pc ? they usually have the recovery bios in it

    with EFI it uses compress in file. but not same in rom.

    please dont msg me as whatever i have to say i posted already... im not sure if this one is recoverable by hexedit the files.
    the G73 i did worked. but this looks different. EFI ?

    2nd link looks promissing!
