Re: Panasonic CF-51 BIOS Password
@gius0161
Seems to me that this Panasonic Toughbook CF-51 (mk2) is an old model, that still haves a parallel port, so one solution is to build the "Password Skipping Plug". Unfortunately this only seem to work just for the USER password.
In old models the password used to be stored in EEPROM, did check your files. My suggestion is to look for an eeprom near the EC/KBC (check on both sides).
Did some Google searches and found a link to AllService forum and to laptops.shoutwiki.com, you may be able to follow procedure posted at AllService to reset the password by updating the EC/KBC and BIOS.

When "Enter password" is displayed, use "Password Skipping Plug" in order to skip the user password.
1) Connect the parallel plug to the parallel port.
2) Connect the PS/2 mouse plug to the mouse port.
3) Power on the computer.
The wiring of the parallel plug is described below.
Connect pins 2-5-6-8-11-13-15-18-19-20-21-22-23 to Shield GND (PS/2 mouse plug pin 3.)
Connect pins 3-4-7-9-10-12 to VC5 (PS/2 mouse plug pin 4) with 4.7KW each.
