    Retting BIOS Chip by a short

    Hi,

    I am currently trying to remove the BIOS Password. I have a W25Q128JV chip which stores my BIOS on.

    I have checked the manual online and it says that pin 7 is a /HOLD or /RESET.

    If I shorted pin 7 out by adding it to a ground would it remove the BIOS Password?

    4.6 Reset (/RESET)
    A dedicated hardware /RESET pin is available on SOIC-16 and TFBGA packages. When it's driven low for
    a minimum period of ~1µS, this device will terminate any external or internal operations and return to its
    power-on state

    4.4 HOLD (/HOLD)
    The /HOLD pin allows the device to be paused while it is actively selected. When /HOLD is brought low,
    while /CS is low, the DO pin will be at high impedance and signals on the DI and CLK pins will be ignored
    (don't care). When /HOLD is brought high, device operation can resume. The /HOLD function can be
    useful when multiple devices are sharing the same SPI signals. The /HOLD pin is active low. When the
    QE bit of Status Register-2 is set for Quad I/O, the /HOLD pin function is not available since this pin is
    used for IO3. See Figure 1a-c for the pin configuration of Quad I/O operation.

    This doesnt work on newer mb's. So better take out the chip from mb and read it with a spi bios prorammer. This saved bios dump you can post in "Bios Section" for help in removing password.
