Panasonic CF-48 Bios Problem

Try a BIOS Reinstall

I have a cf-48X4 1.8 ghz that I sucessfully removed the password from.
Backup all of your data that may be important. Be certain to have a charged battery and the charger plugged in, as a power interuption will likely cause irrepairable harm during a bios operation. If you are not reasonably confident in performing this operation you stand the real risk of messing up your computer. It is also wise to double check any information I have supplied here for accuracy. The Flash program doesn't work with every mother board.
GOOD LUCK! If your computer won't access the floppy during startup because of bios settings and it starts windows instead.... remove your hard drive and it will acess the floppy.

First copy a new release of uniflash from http://www.uniflash.org/download.htm.... download uf138.zip.
Get a floppy disk and format it for dos booting right click on a: in my computer select format then select create ms-dos disk. Make careful note of the bios, mine was v4.00L10 it can be seen during startup if you look quickly. If you need the same copy as I have I will be glad to mail it to you free. After disk is formatted unzip uf138.zip and paste the unzipped copy on the floppy.
Now install floppy in your cf-48 turn on your computer at the a:/> propmt and type "uniflash" it will ask if you want to copy the bios to a backup file on your floppy. say yes. mark your floppy and store it safe, it will at least bring you back to where you were.

Now go to http://tcc.toughbook.com/pcsc/tcc/tgportal.nsf copy the latest bios and pay close attention to the model numbers mine is cf-48X4KNUQM and be certain to select the correct bios. Otherwise you may end up with a dandy looking door stop. The new BIOS program you'll download and open will need to create another floppy so have another floppy blank handy. To install the new bios install the new bios floppy in the computer and turn it on. It will self install. The new bios was useful and it worked in my case to clear the password, however i found out that the product recovery CD no longer worked with the NEW BIOS It may only be a problem with my model only however. Install the new bios see what happens. It may not effect your product recovery CD's at all. It erased the password okay in my case and I reinstalled the bios from an identical unit that did not have a password. You may reinstall your old bios (if you need or want to) with the first disk you made and it may leave out the password data. I did all of this today and it worked for me. It was my first time copying BIOS from one computer and putting it on another, both had the same chipsets. It was pretty easy. Be certain to have a charged battery and the charger plugged in as a power interuption will likely cause irrepairable harm during a bios operation.

Christian,

I attempted to follow your instructions above, got as far as downloading the uniflash file, but never got to use it because I could not get an updated BIOS file from Panasonic. There is just nothing for the CF-48 as far as the BIOS is concerned.
So, I just kept searching and searching the internet and came across this link:

http://www.tech-faq.com/reset-bios-password.shtml

The back door password that worked for me was: CMOS

Can you believe that? I even called Panasonic support and they said the only option is to send it in to get reset ($130), or use a third-party software.

Well everybody, I hope this works for you!
