    Bios read help fot HP 830 G5

    Hello,
    I would need help for reading a bios on 830 G5 .

    No desire to retire the chip and I tested with wires on TL866II

    but I can’t read it . this is a MX25L25673G

    It’s not recognized by the programmer.
    Chip id not correct and Full FFFF in read .

    I took the advice here with the charger but no better.
    https://www.badcaps.net/forum/showthread.php?t=79911


    He didn’t make it.

    An idea, an advice please

    I don't think 256Mb chips are supported by that programmer.

    I used raspberry pi + latest flashrom for that size.

        The MX25L25673G is in the support list. I have the older tl866cs ,i get errors like that when a chip isn`t seated properly in the adapter or zif socket.

          Ok, this is the clip that falsely reads, I solder directly


          This is why, you must always control its reading.
          I really don't like the eprom clamp

              What sort of clip do you have,a cheap one or a pomona.Its always more reliable desoldering the bios

                      the chip was soldered directly to a programmer support, I no longer use the clamp
