    I have flashed firmware on other devices (not laptops) where the chip could not be unsoldered from the unit. There are "glomper clips" that can attach to SOIC package on the motherboard that contains the BIOS. You would need to work out the communications method and copy off a good BIOS from another laptop or use a BIOS package to push code back down to the chip.

    Years ago, when that was my job I could accomplish such a feat in an hour or two on a system that I had no previous experience with. These days I lack the hardware and software tools to recreate it. The task would take me several days to scrounge together the pieces-parts and to work it all out. It is not outside the capabilities of an engineer or a talented technician to recreate the process.

    At the worst, you could use solder-wick and some skill to remove the SOIC chip from the motherboard; Or use a hot-air system and tweezers. Then you could pop the chip in to a programmer and push a new BIOS on to the chip.

    I have even done the same thing with FPGA devices, those are much more complicated than a simplistic BIOS memory device.

    As has been said; this is not to break or bypass passwords. I would suggest that you go through the BIOS and copy down every value that is in there because you will need to build it back out after you replace the BIOS with a different version.

    The M22 bios is the problem,I had 3 former US Navy units with the same bios and sad to say ,it is impossible to fix. A PCMCIA wifi card will work but usb wifi will not.

    3.01L23

    3.01L16 M22

    The M22 indicates a custom BIOS. Wifi and BT are more than likely permanently disabled in the custom BIOS.

    Does BT of wifi show up in BIOS?
    Are they enabled?

    Usually not with the custom BIOS. Panasonic has them locked out from updating.
    PCMCIA wifi will work. Also if you do the pin 20 mod on the wifi card, it may work.
