      Panasonic CF-54 MK3 Bios Password

      After copying another similar machine BIOS, I was wrong about not booting-simply had forgotten to replace memory. Even though I searched/replaced serial number, the donor BIOS machine serial number showed up. Additionally, the ME Firmware was not present. When I tried to run the batch file to write ME Firmware, it would fail. I fiddled with batch file to bypass checks with no sucess and I also ran update exe from cmd. Maybe with more time, could get this to take but I went back to the PW removed BIOS provided to me by @peste. Same as before:

      "Have tried again the L25 BIOS update, same behaviour with stopping at update screen.

      These two updates worked:
      -Embedded Controller V3.00L13 to V3.00L14
      -ME Firmware 11.8.60.3561 to 11.8.82.3838

      Also, I notice under Panasonic PC Setting Utility / PC Information Viewer / Setup:
      ...
      BIOS V3.00L17
      BIOS Configuration 0014-FFFF-00D5
      Sample ID ÿÿÿÿÿÿÿÿÿÿÿÿÿÿ < Do not see this line on similar machine
      Embedded Controller V3.00L14
      ..."

      I'd appreciate any suggestions to correct the L25 update issue. Thanks again.

                        Re: Panasonic CF-54 Bios Password

                        Hello Guys,

                        i have a Toughbook CF-54 Model No. CF54CY004EG and Serial No. 6ATCa41920..

                        After a "load setup defaults" in bios, the toughbook surprises me with a bios password, which was not used before. Unfortunately the setup defaults switch my boot devices, so I can boot only via USB Stick. For this reason I can dump bios via freedos programm only. I tried some afudos vesions without success. Flashrom asks for the right Flash-Chip, have no clue how to find this out.

                        I read this hole thread and the "how to" thead carefully.

                        My question is:

                        How can i dump the bios?

                        Thank you!

                        Greets. Sebi





                        I read all the bios stuff ca

                            Did you tried already to remove the password, or it was someone else's job?

                                No, it's not the old one. I saw, I saw that someone tried already.
                                Well, it wasn't a very successful attempt, but he still tried. That's why I asked if it was you, or someone else.

                                          Seems like you used a software utility to read the BIOS, so file is empty (FFh) from 0h to A00000h (first 10MB), in this address range is where the Descriptor, GbE and ME Regions are located. So basically your file is just a dump of the BIOS Region.

                                          We use a software utility to read a BIOS when the password can be recovered from it, for a CF-54 you need a FULL bios backup obtained using a SPI programmer.
