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:...

Re: Panasonic CF-54 Bios Password
@AAAC or other expert, can you please explain “clean ME region”? On my cf-54 mk3 (which password was removed but cannot update bios), I will attempt to copy updated bios from similar machine, changing serial number and cleaning ME region. Thank you....Leave a comment:

Re: Panasonic CF-54 Bios Password
Have tried the L25 BIOS update three times, 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 the line :
...
BIOS V3.00L17
BIOS Configuration 0014-FFFF-00D5
Sample ID ÿÿÿÿÿÿÿÿÿÿÿÿÿÿ < Do not see this line on similar machine
Embedded Controller V3.00L14

Re: Panasonic CF-54 Bios Password
Thank you, the password is removed. I do not know if related but appears the BIOS update (from L17 to L25) is hanging at reboot from Windows. Getting longer than usual pause before Aptio Setup BIOS update screen, warns about not shutting down and then does not proceed update nor reboot. Any ideas?Leave a comment:

Panasonic CF-54 MK3 Bios Password
I'd like to ask forum experts to help with another password removal. This is BIOS from CF-54 MK3 using CH341. Machine will not boot to disk, only asking for password. Thank you.Last edited by SMDFlea; 04-03-2023, 09:34 AM.Leave a comment:

Re: Panasonic CF-54 Bios Password
Hi, can I use one of the bios files with password already removed or is it necessary for someone clear mine? File is from CH341. Thank you.Last edited by SMDFlea; 04-03-2023, 09:34 AM.Leave a comment:
